Putin signs law legalizing Bitcoin & other cryptocurrencies, lifting them out of Russian legal 'grey-zone'

Digital financial assets, including cryptocurrencies, will be permitted to сirculate legally in Russia soon, but if you're planning to go shopping with bitcoin, or other variants, forget it. They won't be legal tender.

Private by design decentralized p2p marketplace

Hi fellas, this is my first ever post on privacy.
I recently wrote about the existence of an open source DLT-based decentralized marketplace with a mission to enable free and private trade of goods and services. The marketplace description was posted on another subreddit but I think it's worth posting the description here too. Tbh I cant think of anything that qualifies more as "The intersection of technology, privacy, and freedom in a digital world"
I hope my own description of the marketplace and its technology bellow will fuel your interest to read more about it. My even bigger hope is that some of you will decide to become first-hand beta testers as soon as the upcoming v3.0 of the marketplace hits the testnet (eta: a few weeks).
You can also use the existing version (currently 2.3.5) of the marketplace to buy or sell products on the publicly accessible single community market there (or just play with it).
The marketplace:
It is called the Particl Marketplace and its ground breaking V3.0 is set to be released after 3 years of hard development work. The V3.0 will be the first version aimed at a wider public (normies and not only tech geeks). It will allow anyone to create easily decentralized personal storefronts or community markets or simply buy/sell goods on existing markets. The user-created markets/storefronts on the marketplace can be public if the access key is publicly announced on the Particl network or absolutely invisible to anyone that doesn’t know the access key (held by the creator). This is an intentional privacy feature and simply put, if you dont have the market access key (essentially a decryption key) there is absolutely no way to see/detect that some market exists.
The marketplace is private by design and decentralized, with no middlemen or intermediaries whatsoever. The trades are protected by a two-way automated escrow via smart-contracts that de-incentivize and penalize dishonest behavior on both sides. In particular, the buy-flow forces the buyer to deposit 1x item value + payment and the seller 1x item value (+ sends item) into a common smart contract. If the buyer receives the product/service and its all good, then he unlocks the escrow so both can get their 1x item value deposits back and the seller receive his payment.
The marketplace takes no sales commissions from the storefronts/markets and charges only a tiny listing fee (<0.01$) to prevent product listings spamming. All the marketplace generated fees go to the staking nodes that provide the hardware infrastructure for the p2p network to operate. The network nodes can be public or you can run them as Tor hidden services.
The technology:
The Particl Marketplace is crypto-agnostic and currently supports payments in BTC, PART, ZCoin (XMR, DAI, NIX, USDC, USDT are next in the pipeline and many more to come). It uses as a settlement layer its native coin PART and own blockchain, which is an up-to-date Bitcoin codebase with added privacy features like CT, RingCT (up to 32 mixins), Stealth addresses, etc. These privacy features are used in combination to keep the financial data, like escrows and transactions, private and most importantly un-linkable to the actual market buys/sells.
For the users and markets related data exchange like posted listings, buy/sell flows, encrypted user communication, built-in cryptocurrency exchange, etc, the marketplace uses a DSN, currently its a custom Bitmessage variant called SMSG, which allows metadata stripped encrypted p2p data exchange (no sender, no receiver)
Last but not least the marketplace desktop app (Particl Desktop) has a built-in option for using the Tor network via proxy.
The important people:
The cypherpunks behind Particl Marketplace have been OGs freedom advocates and pioneers in the privacy DLT field. For example, they were the first ever to implement features like RingCT, Bulletproofs, PoS, cold staking, etc on a Bitcoin codebase. Their privacy features implementations have been audited successfully by several respectable academics and security R&D providers, like QuarksLab.
The team behind the project has been so far focused on building without any marketing/awareness efforts and thus have remained intentionally in the shadows. The latter is planned to change with the v3.0 release. One of the steps towards that will be the initiation of several long-planned awareness campaigns, like the Vendor Onboarding and Outreach Program, the Particl Academy (an easy to understand and learn about the technology portal) and many more.
Me:
I am a passionate freedom and privacy advocate that discovered the project 1.5 year ago and since then has become a member of their small but like-minded community ([email protected]/discord).
My personal belief is that the Particl Marketplace provides a game-changing/breaking usecase to the world. At the minimum, due to the open source nature of the project, it will be a proof of concept that is bound to shift the global eCommerce paradigm.

Open Marketplace by Particl

Hi fellas, this is my first post on the darknet. I read today about the Empire Market and decided to post here about a tech that might help to end this charade of constant exit scams.
My post is about a DLT-based open source decentralized marketplace that will hopefully initiate a paradigm shift in the free and private trade between individuals and ends the exit-scams and leaky databases problem once and for all.
It is called the Open Marketplace V3.0 and is set to be released after 3 years of hard development work by Particl Project, including one year of public beta testing.
My personal belief is that they are releasing to the world a game-changing/breaking product. At minimum, due to the open source nature of the project, this is a proof of concept that is bound to shift the global eCommerce paradigm into DeCommerce.
I hope my own description below of the marketplace and its technology will fuel your interest to read more about it. My even bigger hope is that some of you will decide to become first-hand beta testers as soon as the Open Marketplace v3.0 hits the testnet (eta: a few weeks).

The marketplace:
The Open Marketplace is designed to be private by default and decentralized with no middlemen/intermediaries whatsoever. The trades are protected by two-way automated escrow via smart-contracts that de-incentivize and penalize dishonest behavior on both sides.
The Open Marketplace takes no sales commissions and charges only a tiny listing fee (<0.01$) to prevent listing spamming. All the marketplace generated fees go to the nodes that provide the hardware infrastructure for the p2p network to operate. The nodes can be public or you can run them as Tor hidden services.
The V3.0 that is set to be released will be the first version open to the wider public. It will allow anyone to create easily a decentralized personal storefront or a community market or simply buy and sell goods on the already existing markets. The user-created markets/storefronts can be visible on the marketplace if the access key is publicly announced or absolutely invisible to anyone that doesn't know the access key (held by the creator). This is an intentional privacy feature and simply put without going into many technical details, if you dont have market access key there is absolutely no way to see/detect that some market exists.
The technology:
The Open Marketplace is crypto-agnostic and currently supports payments in BTC, PART, ZCoin (DAI, NIX are next in the pipeline and many more to come). It uses as a settlement layer its native blockchain, which is an up-to-date Bitcoin codebase with added privacy features like CT, RingCT (up to 32 mixins), Stealth addresses, etc. These privacy features are used in combination to keep the financial data like escrows, transactions, etc private and most importantly un-linkable to the actual market buys/sells.

The three things that keep me up at night.

Tonight I read this article and while it doesn’t get too deep into the technical weeds, I thought I could do better by breaking down some of the IT threats and concerns that keep me up at night into more of a non-tech person’s language while giving real world examples why this stuff really does matter to everyone, not just the uber nerds, naysayers, and tinfoil hat wearing conspiracy theorists.
https://nakedsecurity.sophos.com/2020/09/18/a-real-life-maze-ransomware-attack-if-at-first-you-dont-succeed/
Security (both digital and physical) is something most people don’t understand and as a result they act like an ostrich by burying their head in the sand; if I can’t see it, it can’t see me. Until recently I was an IT consultant and would frequently bring this up to my clients. The usual reply I hear is along the lines of “but my company doesn’t have much money, isn’t a bank, doesn’t do anything interesting, etc. so they aren’t going to target me and I don’t have anything to worry about.” Sadly, this isn’t the case. These crooks “spray and pray” and will victimize anyone who gets caught in their snare. They will send out hundreds of millions of emails, compromise thousands of websites, and make tens of thousands of robocalls all with the expectation that they are only going to be able to victimize 0.0001% of their attempts.
For years there have been two big threats in the IT world that literally keep me up at night; regulatory compliance and ransomware. There is now a third, extortionware.
Regulatory compliance is an area business owners and executives commonly overlook because they don’t think it applies to their company because they’re not in health care or banking. PCI (Payment Card Industry), PII (Personal Identifiable Information), HIPAA (Health Insurance Portability and Accountability Act), and HITECH (Health Information Technology for Economic and Clinical Health Act) are the most common compliance standards and now cover just about every company in existence in the United States. If the company takes credit cards of any kind there are some levels of PCI compliance that they need to be adhered with. PII covers most HR information like social security numbers or driver license numbers. HIPAA and HITECH both cover information related to health records. This is one that most companies overlook because they don’t realize things like workmen’s compensation claims, HR records that discuss health related issues, etc. are all covered by these standards. Fines from the governing bodies that cover their respective compliance standards are usually preventable because they have general guidelines that cover what needs to be done to be in compliance on the logistical, physical, and digital fronts. If your company does anything with the European Union, then GDPR (General Data Protection Regulation) is a new regulation that has some pretty serious consequences if not followed properly.
Ransomware is a genre of computer virus that is just evil. It encrypts your data and give you a very short period of time (typically only a couple days) to pay the ransom using untraceable funds transfers via cryptocurrencies like Bitcoin. If you don’t pay the ransom in time they will delete the decryption key thus destroying all your data. If you do pay the ransom then chances are you will get your data back however you are likely very literally funding terrorism and/or some other kind of organized crime. These ransoms are also meant to be payable but be painful to pay. The newer ransomware variants will scan your network to get an idea of how big it is then adjust the ransom accordingly; the more devices, the higher the ransom. Typical ransoms start around a few thousand dollars and work their way up hundreds of thousands or even millions of dollars. If you’re infected with these viruses then the best course of action to remove it is to wipe your entire network (all servers, workstations, firewall and switch configs, etc.) and rebuild it from scratch while restoring your important data from backups into a separate clean environment, scanning it for any traces of the virus, then moving it into the newly rebuilt network. While this is typically more expensive than paying the ransom it is the only way you can be sure the virus is no longer on your network and thus capable of infecting everything all over again and repeating the ransom process.
Extortionware is similar to its older sibling ransomware in that the virus typically does all the same things however it adds an even more sinister twist, it copies your data offsite to a server only the criminals can access. They do this because of the increased number of companies that have opted to not pay the ransom and just rebuild their network. Using extortionware the criminals now have the company’s intellectual property (usually proprietary), HR data, internal memos, financial data, emails, etc.. Did someone say something unflattering about someone else in an email, did HR have a spreadsheet with every employee’s SSNs, hire dates, etc., or are there private financial records relating to an upcoming acquisition that your competitors shouldn’t know about? All of this and more will be used by the criminals to extort money from the company. This means that even if you have a rock solid backup of all your data, you still need to pay to prevent your data from being released to the public and/or press.
While this post just scratches the surface, it does cover the highlights on why I push for stronger passwords (longer is better than higher complexity https://xkpasswd.net), keeping non-company owned and unmanaged devices off internal networks, multiple factor authentication on everything, never sharing your passwords with anyone, running regular security related exercises, using unique passwords on everything, and using a reputable password manager to keep track of all your passwords.

Have anyone tried his decryptor?

https://www.youtube.com/channel/UCaXG3Ihua8weOkYOrvLgZTA
I am infected with lalo ranswomware and I came across this youtube channel . I have an olnie key and people say that decryption is imbosible. But I wrote to his email and sent him some of my infected files to try. And I found out that he can succesfully decrypt photos, videos and audio files.He sent me a preview with the real content of te video or photo that I had before it got encrypted. I asked him to sent me his decryptor and he told me that he will send me his decryptor If I donate him, but I can't becase I don't have neither debit or a credit card r bitcoin. I am not sure If I donate him eventually in the future that he will send me a decryptor. He has a decryptor that works for every new variant of STOP/ DJVU. It just contain 3 files - dec.bat, dec_util.dat and dec_util2.exe and you just click on dec.bat and it magically decrypts your file. If decryption is impossible, how does he do it? How is his decryptor done? I want a decryptor like this!
Did anyone have contacted him, dontated him? Did he sent a decryptor? Did it work for you?

Please recommend me a seedbox - large-ish storage on good network

Recommendation form
Are you OK with direct message offers from vendors?
NO but you can reply here and ask me for DM 
What are your main reasons for getting a seedbox?
I run rtorrent, plex, sonarr, a couple of other things 
Do you have any specific requirements?
The seedbox I am looking to replace (price jump) has 32GB of RAM and 32TB disk. I am not hurting for ratio so I could go to 16GB RAM and give up the pagecache. I'd like to compare options between 32T and 16T 
Are you looking for a shared or dedicated solution?
Dedicated. 
Are you looking for managed or unmanaged solution?
Unmanaged. I want to do everything - starting with installing the OS - myself. A slight plus to a hoster who can advise on seedbox tuning (advise me ... not do it) 
Please describe your Seedbox experience:
Good? 
Currently with a provider or used one before?
Yes - down to two seedboxes and this would be to replace the deep-storage one. I've had up to 4 going at a time with different providers in the past. Consider my post as a 'market check' from somebody who understands this space but hasn't looked around in a year or two. 
What is your Linux experience?
Scale of 1 to 10 - I'm 11 
What is your monthly budget?
could pay 100 USD but would prefer 50 
Payment preferences or requirements?
Nothing strong - cc, paypal, bitcoin fine. Would like to avoid monthly toil to pay - automatic billing is good. I am ok with quarterly or annual if I trust the provider. 
Do you need support for public trackers?
No. 
Routing: Tell us your continent:
North America 
What kind of connection speeds do you need?
1GB is fine 
How much monthly bandwidth is needed?
I can fit in 100TB 
How much disk space do you need?
32 would be equivalent to current box. 24 might be sweet spot but would look at 16 
List some features you are looking for:
Dedicated server in europe - 16g 16t minimum - prefer 24 or 32 full control from os install up - assume I'm using a non-debian variant 
Anything else you think we should know?
I think I got it all - so summary: This box isn't for racing - it's deep storage. It only joins torrents that I've already completed on another seedbox, or sonarradarr wishlist items which are ok with a little delay to join.

I'm playing this game since patch 0.2 (yeah, one decimal ) and the game came a very long way (Appreciation Thread)

Recently I'm playing at Star Citizen, it's the second game that I'm opting in at Alpha status (yeah, when I joined in 0.2, Game was Alpha, not for much tough) and considering they had the same length of development, and you can sorta say they are SORTA similar in scope, I have to say the devs in EFT put way more effort into bug squashing to make the game enjoyable for everybody at any point. And this is a post to Thank them and Nikita, but also to go a bit down memory lane and remember how the game was

I was there 2000 years ago, here are a few things that I remember made the game miserable, so you can put it in perspective for any means and purporses :D


-When you bought the game in Alpha, you had 50% to being selected to play, otherwise, you had to wait for the beta (I was lucky to get selected)
- Only 3 armors: Paca, 6B43 Zabralo-Sh 6A Armor, back then called Fort by everybody and the rarest Gzhel
- Basically 9 weapons: M4, Ak74 (and u variant), AKM, Kedr, MP5, Sv-98, Saiga, Mp 133 and 155, maybe AsVal but I don't remember and variant
and 4 Pistols Makarov, TT, Mp-443 and P226R
-Ammo? 1 or 2 types of ammo for weapon at best. Shotguns had bucketshots and slugs, that's it
-Blunt Damage inserted in, SLUGS were THE BEST ammo you could use, at any range.
-You were forced into door opening animation for all doors, even not locked ones
-Bug of doors opening without animation and suddenly, giving the opener a big advantage
- No Jager, No ragman, No Mechanic
-No FleaMarket (Fence was "the fleamarket")
-One NVG
-Only 3 rigs, Scav vest, AVS, Blackrock, the latter 2 basically being a commando Vest in dimensions, neither of them being armored
-No hideout
-Instaheals, spamming meds while in combat
-Insta bullet drill, basically you could go in raid with just a scav vest and 2 magazines
-Trash net code, like 2 seconds of advantage peak, trade killing was very often
-Desyinc, the game was BASICALLY unplayable at points, too many disconnections, too many servers going haywire (like 2 out of 3 games)
-Flying cheaters (YES, NOCLIP)
-Factory, Woods and Customs only maps
-Then came Shoreline, first new map, only half of it, the extract was at tunnel and the military bunker just before the sanitarium, people fought basically in the swamp and in town -NO SCAVS in the first Iteration (also happened for Interchange, no scavs)
-Scavs changing from: loot pignatas, to terminator, to loot pignatas a lot of times
-Scopes? you mean PSO
-most coveted item being: Physical bitcoin, and roler watch
-At around 0.5 you could stack armored rig on top of your armor, imagine a 6B43 with a TacTec on top, armor stacking :), and of course no weight limits
most recently: Head going through wall and noclipping the area around bug

If you too are a player of long date, you can expand this list if I missed something.

It's been a few years, and the game is greater than ever and is only going to get better, keep up the good work boys

EDIT by Community ;):
-Woods map was in at the time
-Everybody spawning at the same side of the map
-Quests had a time limit, and you could lose your progress (and items) in the quest
-Quest were very few, like 4 or 5
-No partial turnover of items, you need to give all the items togheter, unless they are separated. i.e: delivery 2 fort armor and 2 ghzel, you needed to have 2 fort armor in your inventory if you wanted to give them
-At one point, If you had a map equipped you could choose which side of the map to spawn
-If you had one black limb, touching barbed wire meant death
-Beign shoot at one blackd out limb would mean sure death
-Roubles used to stack at 50k, you had no money case and no doc case, the only way to store them was with wallets
-You could level up vendors by selling them rigs of backpacks full of stuff, skier was the most exploited since he doesn't buy guns, you can just put stuff inside you backpack and sell everything to him
-Similar to the precedent point, you could sell bag full of stuff when fleamarket was first introduced, a lot of scams and mistakes were made in that time
-(recent)You had to wait an entire 1 minute to revoke a flemarket posting, if you did a mistake it was basically gone
-(recent) you could sell your gamma container on fleamarket, after wipe people usually sold them
-Backpacks? T-Bag, DuffleBag, Scav Backpack, MBSS, Trizip and Pilgrim
-Customs had only one choke point, the wall at checkpoint that goes on until gas station and dormitory was the outermost part of the map, no derailed train, no power pole maintenance area
-Scavs position were much more predicable overall, you could always found them in specific places if you were the first to get there
-No scav bosses at all
-(Very Early) No Peacekeeper
-(Very Early) no group spawn
-(Very Early) sticky grenades
-(Very early) No time selection
-The only way to finish "what's on the flashdrive" quest, was with USB flashes spawning on the tent in woods
-Only one head hitbox, an helmet would cover the whole face
-There was a brief period where some helmets were completely broken (after face hitboxes), skull facemask
-(recent)No possibility to restore blacked out limbs, a black stomach would most likely mean death in a few minutes if you didn't bring any water in

Common sites with HIGHEST payout and STABLE income << 04/10/2020 >>

This is a long post, but please try to read it all and select the most suitable one for you. When you see any sites with good payout and good potential, feel free to create a post. Also when you know site that is scam, please create a post to alert everyone as soon as possible.

There're 4 main and common types of task you will encounter when using beermoney sites. You can use all the sites or just pick the most suitable type and site to work with. Using a number of sites is recommended, as the number of tasks on one site is not high enough, and the tasks will not appear continuously.

I. MICRO-TASK (also know as Crowdsourcing task)

The task is vary from article assessment, information collection, search-query classification/answer relevance, taking or collecting photo/video, to object identification,... The number of tasks will increase as you complete tasks.
Pros:
- The number of tasks is higher and more stable than other type of beermoney.
- The payout is appropriate to your time and effort. You can even make stable income with them.
Cons:
- Sometime you will need to pass the training test to access the task.
- Your work may not be accepted if it does not meet the guideline.
- It can be a little hard in the beginning. There's also not many tasks for you, but BE PATIENT, because they haven't been able to fully assess your ability yet.
1-Toloka Yandex:
This is one of my favorite micro task sites, and is the first on the list when I make beermoney site suggestion.
The tasks are mainly in English and Russian. They also have task in your mother language too, depend on your setting and location. Don't worry about the language, as you can easily have it to be translated with google translate extension or any translation site and the task is easy enough to understand.
The minimum withdrawal is $0.02 if you request to withdrawal once a week, and it will be $1 if more than once a week. You can withdraw the money to PayPal, Payoneer, Skrill or papara. But to be able to withdraw with PayPal, you will need a verified PayPal account.
Here are registration links: ref-link and no-ref
2-Clickworker:
One of the most popular micro task sites, you can find many recommendations and good reputation about them. But to make the most if it, you will need to unlock UHRS, as describe here.
You can receive payment with PayPal.
No need to say anymore, here are the links: ref-link and no-ref
3-Neevo DefinedCrowd
Another micro-task site you should take a look. The tasks is quite similar to other micro-task sites, with good payout. The tasks can be transcription, image collecting and verification,...
You will need to do some language test to be able to access task. The tasks are list on dashboard, but usually they will invite you through your email.
You also will receive payment via PayPal.
Note: in order to receive as many tasks as possible, when you're asked to input languages you can use, make sure to input languages together with it variants. For example, you can use English, and it has English for American, English for Australian,... then you will select all that variants
Here is registration link: no-ref
4-Remotasks
You will need to take part in training and pass the test to be able to access a large number of tasks here. The tasks are categorization, text highlighting, image annotation, semantic segmentation,... and well-known Lidar Annotation and Segmentation.
With enough training, you will make stable income with this site, and the payment is sent to your PayPal account.
Here are registration links: ref-link and no-ref
NOTE FOR MICRO-TASK:
  1. It's high recommended to use all those sites, and maybe other sites if you want, because the tasks are not shown continuously.
  2. Make sure to fully understand the guideline, as you will not be credited if you work fails to meet the requirement, which will waste your time and effort.
  3. If you find any task with really low credit but require a lot of time and effort, don't do it. If the requester still be able to find worker, they will always offer that price. It's not worth your time, just going to other tasks or going to other sites to see if there're any available tasks for you.

II. OFFER WALL TASK

Another way to earn beermoney online is to complete Offer wall tasks. You will be asked to installing app on your smartphone, signing up, playing game and reaching determined level, or watching video,.... Doing survey can also be listed here, but it will be shown in separate section.
There're many offer walls for you to choose, with different payout level. Usually each beermoney site will list many offer walls, one offer can appear in more than one site/wall, so make sure to surf around and compare the credit to find the best and highest payout wall/site to complete that offer.
Pros:
- Easy to do
- Can complete offer many times if you have different kinds of phone (mostly Android and iOS), or using another phone as the tasks are listed on many different offer walls.
- Can earn money while playing and relaxing, as mostly the offered apps are games. Some apps only requires you to install and open, make it really quick to have some beermoney.
Cons:
- The payout is not very high. Especially when that offer is going through many walls and sites to reach you.
- Some offer take much time to complete.
- The number of offer is not high enough to do daily.
1-RewardXP
RewardXP has surpassed GG2U to become the highest payout site. They have leveling system, the higher level you reach, the more offer walls you can access and the more benefit you can get.
With the minimum of $5, they provide a variety of withdrawal methods for you to choose, like PayPal, Amazon, Steam,...
You definitely should try this site. Here are your registration links: ref-link and no-ref. Registration with referral link, you will be given a 5000XP (~$0.5) bonus.
2-GG2U:
This is also my favorite site. Their paying rate is one of the highest in the market (if you find any other site which is higher, feel free to suggest :D THE HIGHEST ONE NOW is RewardXP, see above). Aside from installing and registering app, they also have many survey walls for you.
The most attractive part is that they will give you $1 bonus right after signing up, and after 5 withdrawal requests, you will have a chance to earn up to $7 bonus. With bonus, it's hard to say which is better, RewardXP or GG2U.
You can withdraw money to your PayPal account or Coinbase (crypto wallet), with the minimum of $7.
Here are your links: ref-link and no-ref
3-Cointiply
One of the most popular sites, with great community.
They will pay you with cryptocurrency like Bitcoin or Doge. You will have many chances to earn coins, by doing offer walls task, rolling the faucet every 1 hour, testing your luck with multiplier or by activating in their really crowded chat room.
You can also earn some coins by clicking Paid-to-click ads. Most of the time, those ads are from Cointiply user with their referral link embedded, so if you register sites when viewing those ads, they will earn some commission. You can try this strategy too :D
With their mobile app, it will be much easier to do mobile offers. Make sure to check your email and mobile app to get the user-limited Promotion Codes regularly.
Registration links: ref-link and no-ref
4-Swagbucks
Sometime you can earn money by spending less. Swagbucks offers a big number of sites where you can receive cash back when you shop online. If you shop online a lot, it's worth to take a look
Here are registration link for shopping: ref-link-shopping and no-ref-shopping
Beside the cash back program, Swagbucks also provides offer wall, however the paying rate is not as high as those 2 sites above. Anyway, if you want to try, here're your registration links: ref-link and no-ref
5-EarnCrypto
If you're into doing offer walls task and earning crypto currency, try take a look at this site too.
Their paying rate is quite lower than 3 sites above, but they have Data entry task, which is daily, for you to earn some coins. By ranking high on their daily leader board, you will be rewarded with a great amount of coins (can even be higher than your earning from doing the data entry task itself :D).
There are many different kinds of crypto currency for you to select.
Just take a look if you have time: ref-link and no-ref
NOTE FOR OFFER WALL TASK:
  1. Every offer wall has a place to track your activity history, like what offer you clicked, what offer you completed and did you receive credit or not. Every time you're about to do an offer, after entering that offer (usually when you click an offer, a small panel about what offer is, there will be a button name 'continue' or 'go to offer', after you click that button, you're entering the offer), make sure that offer appears in your history tab of the offer wall. This will enable you to request support in case you complete the offer and have not received credit yet. If it have not appear in the history list, you will not be credited for that offer, so try to click it again.
  2. To find the history tab, after entering offer wall, you will need to find a button named 'My coin', 'My history', 'Support', or button with question mark,... That button should be easy to be found.
  3. Try to surf around the find the offer wall and site having the highest paying rate for the offer, as the same offer will appear in many offer walls and sites.
  4. When you're about to start to do an offer of installing app (especially game), try to read the comment in appstore/playstore to see whether the offer's requirements can be easily to fulfill or not. For example, the requirements are: 1. install game, 2. open it, 3. reach level 30; and you find some comment about cannot reach level 25, or it takes months to reach level 29, then skip that offer, it's not worth the try.

III. PAY TO SEARCH

You can earn nearly passive income from this type of task. They will give you some query, you will search with that query, entering determined site, leaving that site opened for couple of minutes.
Pros:
- It's super easy to do.
- While leaving the site open, you can do any other thing you want, like doing some micro-tasks.
- The paying rate is quite good, especially when you will not need to do much.
Cons:
- The number of queries is not very high.
1-SerpClix
In order to receive more queries to search, make sure to leave the site open and allow the notification.
Even though SerpClix recommends you to click on the page, don't do that, just using scrollbar. SerpClix will automatically navigate to sub page of that page. Another suggestion here is to install adblock extension, because SerpClix will ban you if you click on any ads on the page, so blocking them before hand is a good move.
Here your registration links: ref-link and no-ref

IV. SURVEY

Probably all offer walls have some kind of surveys there, some surveys are only available through offer walls, some have their own sites. By using their own sites will not guarantee that you will have higher payout though.
Make sure to be honest when doing survey, despite the fact that you will sometime be disqualified from the survey. There's many reasons why you are disqualified, like because your job is not suitable, your demography is not their target, your answer is not persistent,...
BE CAREFUL, they will keep track of you, even if you clear your cookie, so being dishonest can lead you to be banned from their sites. Again, BE HONEST, and there will be suitable surveys for you.
There will be two types of survey for you: the first one is filling form and selecting answer from their suggestion, the second one is to talk with them directly or via Video call apps. The second one has much much higher earning but the requirement is also higher too.
Pros:
- Easy to do, just being honest
- High payout, especially with the second type of survey.
- Some survey only need 5 minutes to complete with good payout.
Cons:
- Some survey can take about 30 minutes to complete, so make sure that you have enough free time.
- You will be disqualified if your information is not suitable to their survey's target. BUT ALWAYS BE HONEST.
1-SurveyTime
One of the best sites out there, my favorite one. They will instantly sent you $1 or $0.5 (depend on survey) to your PayPal or Coinbase account when you complete the survey. You will not need to meet the minimum to withdrawal. The survey you will do here is the first type, filling in the form and selecting answer.
You can register with SurveyTime through some offer walls, as they will give you some coins when you complete the survey.
Make sure to turn on Browser notification and Email notification so that you don't miss any survey.
Registration links: no-ref
2-Toluna
Also a popular survey site you can take a look. The type of survey is also filling in the form and selecting answer. They will send you notification email when there're surveys suitable to you.
You can select payment via PayPal or mobile card, with the minimum of about $2.5
Registration links: ref-link and no-ref
3-Mobrog
This is one of the highest payout survey sites. They also notify you via email when there're surveys suitable to you. They will send you payment via PayPal with the minimum of $6.25
Registration links: ref-link and no-ref
4-Respondent
You will need a microphone and/or webcam (built-in or external) as the survey in Respondent is conducted via video calls, phone calls, in-person discussions. Of course, you will receive a huge credit for doing survey here, from $5 up-to $1000.
They will recommend suitable survey for you, but if you want to view all available survey, make sure to uncheck the 'Recommended' option in Filter panel.
Here're your registration links: ref-link and no-ref
NOTE FOR SURVEY TASK:
  1. sometime, they will provide the must-select answer in the question to test if your attention. Make sure to read the question carefully. For example, the question is "Do you agree that 1 + 1 = 2? Select option [I do not agree] in the answer", if you select [I agree], you fail.
  2. BE CAREFUL - BE HONEST
  3. When you're doing the first type survey (filling form, selecting answer), be careful not to install any app, or download any thing, or upload your social data file when asked. In that case, just contact survey site support and report it.
  4. It's better to use many different survey sites to maximum the number of surveys you receive.

Last word, BE PATIENT - earning online can be a little hard in the beginning.

Feel free to share your experience when using beermoney sites (and your referral link too if those a new sites :D) or ask question about any beermoney sites by creating new post. Also creating new post when you know that any site is scam or becomes scam.

P.S 1: In case you need a Crypto wallet, you can use Coinbase, registration links: ref-link and no-ref, or Binance ref-link and no-ref. You can read here for the comparison between Coibase and Binance
P.S 2: You can add some email addresses to PayPal account, so you can use many email address to register to beermoney sites if you want
P.S 3: If you're confident with your English, and have a computer, microphone and webcam, you can try Usertesting site, you will using the request-to-test site, while talking about your experience.

RiB Newsletter #16 – Secure Enclaves à la Crab

For the last few months we’ve been following new zero-knowledge proof projects in Rust. This month, with Secret Network upgrading their mainnet with secret contracts, it seems like a good opportunity to explore Rust blockchains that are using a completely different privacy-preserving technology: secure enclaves.
Secure enclaves are processes whose environment is protected from inspection by other processes, even the kernel, by special hardware. This protection particularly involves the encryption of a process’s memory. Software that wants to compute in secret can put those computations inside a secure enclave and, if everything works as expected, neither a local user, nor the hosting provider, can snoop on the computations being performed. The most notable implementation of secure enclaves is Intel’s SGX (Secure Guard Extensions).
Secure enclaves are an attractive way to perform private computation primarily because they don’t impose any limitations on what can be computed — code that runs inside SGX is more-or-less just regular x86 code, just running inside a special environment. But depending on SGX for privacy does have some special risks: software that runs in an SGX enclave must be signed (if transitively) by Intel’s own cryptographic keys, which means that Intel must approve of any software running in SGX, that Intel can revoke permission to use SGX, and that there is a risk of the signing keys being compromised; and it’s not obvious that secure enclaves are actually secure, there have already been a number of attacks against SGX. Regardless, as of now, hardware enclaves provide security features that aren’t feasible any other way.
There are two prominent Rust blockchains relying on SGX:
Outside of the blockchain world there are some other Rust projects using SGX, the most notable being:
Whether it’s secure enclaves or zk-SNARKs, Rust blockchains are walking the bleeding edge of privacy tech.

Its core is a computer program written in Java distributed on several hundred computers, as of September 2006, so-called YaCy-peers. Each YaCy-peer independently crawls through the Internet, analyzes and indexes found web pages, and stores indexing results in a common database (so called index) which is shared with other YaCy-peers using principles of P2P networks. It is a free search engine that everyone can use to build a search portal for their intranet and to help search the public internet clearly. Wikipedia

VPN

If you need anonymity and privacy online use Tor instead, if you are looking to bypass a geo-restriction, don't trust public WiFi, or are looking to Torrent, a VPN will help you.

Mullvad

Mullvad is an open-source commercial virtual private network (VPN) service based in Sweden. Launched in March 2009, Mullvad operates using the WireGuard and OpenVPN protocols. Mullvad accepts Bitcoin and Bitcoin Cash for subscriptions in addition to conventional payment methods.
No email address or other identifying information is requested during Mullvad's registration process. Rather, a unique 16-digit account number is anonymously generated for each new user. This account number is henceforth used to log in to the Mullvad service.
The TechRadar review notes that "The end result of all this is you don't have to worry about how Mullvad handles court requests to access your usage data, because, well, there isn't any." Wikipedia

ProtonVPN

ProtonVPN utilizes OpenVPN (UDP/TCP) and the IKEv2 protocol, with AES-256 encryption. The company has a strict no-logging policy for user connection data, and also prevents DNS and Web-RTC leaks from exposing users' true IP addresses. ProtonVPN also includes Tor access support and a kill switch to shut off Internet access in the event of a lost VPN connection.
In January 2020, ProtonVPN became the first VPN provider to release its source code on all platforms and conduct an independent security audit. ProtonVPN is the only VPN to do so, even though experts say this is a crucial factor in deciding whether to trust a VPN service. Wikipedia

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

A trading system based on indicator CCI

A trading system based on indicator CCI
Wikipedia Commodity channel index
Commodity Index indicator is very simple in fact, though it has such a fancy name. Indicators in TSLab are based on C#. For those who have programming skills we provide API and indicator code samples at our Forum. CCI is available in TSLab as other indicators as well, but I would like to demonstrate a self-made one built according to wiki formulas. It is very easy to build new indicators by means of TSLab. CCI consists of Typical Price and Simple Moving Average. TSLab already has all to create CCI, but I showed in the indicator how to create Typical Price and Simple Moving Average. I urge you to study indicators. Making changes to indicators you get a chance to create a better one. Here is a customized CCI indicator. I applied adaptive moving average instead of simple moving average. And I applied exponential average instead of typical price. The chart in the middle shows the original CCI and the self-made one. As you may see their values are identical, as CCI in TSLab is done as it is described in wiki.

https://preview.redd.it/qyo63qnda5q51.png?width=1128&format=png&auto=webp&s=01c60fb93ad72dc72d024fb83aec4ec0d99b40ab
The lowest chart shows the customized indicator. It has clearly seen divergences.

https://preview.redd.it/f3c8vruha5q51.png?width=1913&format=png&auto=webp&s=e8a7aac86d88575907d8792e45e108e1bacb0cfb
Though it is not so unstable as the original one, it seems to be more flat. Wiki offers 2 types of strategies, saying that there are different points of view on this indicator. To build these strategies I am going to use my customized indicator instead of the original one. Some people think that in case with long positions we should buy, when CCI is higher than 100 and sell, when it is lower than 100. And for short positions – Sell when CCI is lower than -100 and close a short position, when CCI is higher than -100. For example this strategy doesn’t seem to be profitable with bitcoin at all.

https://preview.redd.it/xpgqp5xla5q51.png?width=1919&format=png&auto=webp&s=49fa5366938ef780d95c227ec1d549f6a8047077
Other people recommend using zero value as a signal calling this strategy Zero CCI. It means - buy (open a long position or close a short position), when Commodity Index is higher than zero or sell (close a long position, open a short position), when CCI is below zero.

https://preview.redd.it/gyisxbiqa5q51.png?width=1917&format=png&auto=webp&s=1885c903401b9eae93e58772ea46145a2605e47f
Let’s build a script which comprises both variants and resolve the dispute by means of optimization. If we think a bit we can see that there is one more strategy besides these two, this is to use average of CCI instead of signal lines. And we can at least combine all three strategies together. For example, we can enter a position at about zero point. And close long positions when CCI crosses its average, when the indicator is higher than 100 and lower than -100 for short positions. My customized indicator won’t do for this strategy because of divergences. The original one won’t do either as it is not stable and there can be many false signals. Try to create an indicator as flat as mine or even better but with fewer divergences.
Good luck to everyone!

One thing that this game can really benefit from. Heat me out.

Daily and weekly quests that promote PVP.
Right now, there is little incentive to PVP in this game because its high risk and little reward. Its so much easier to just rat and rush loot spawns to make money. People suggest to increase dogtag value to promote pvp, but that will just promote team killing or queue sniping with your friend. Here is an example of what I suggest.
Daily:
kill 10 pmcs with ak variants = 500k roubles
Kill 10 pmcs with 556 variants = 500k
Kill 20 pmcs while wearing class 5 or 6 armor = 1mil
Kill 4 pmcs in a single raid = 1 mil
Etc etc
Weekly
Kill 50 pmcs = 1 mill
Kill 25 pmcs > lvl 40 = 1 mill
This might have some adverse consequences to the economy but it can always be adjusted. Maybe instead of rubles, you could award armor, or a random rare item like a pestily mask or bitcoins.

Building an Ethereum Mining Rig - Part 2

First update to the guide "Building a 6Gpu Mining Rig for Ethereum" - Let's talk about Claymore.
This update supplements and does not replace the Guide to Build a 6GPU Mining Rig for Ethereum published on our site.

The substantial differences are due to the installation of the latest version of the Windows 10 Operating System, the mining on the Ethermine pool (in our opinion simpler than Dwarfpool) and the use of the XFX RX 580 8gb GPUs.

The first variant is found in Part 4 of the guide: the environment variables are not to be entered as they will be integrated directly into the bat file to start mining.

The second variant is found in Part 7 of the guide and leads us to "mine" on a different pool using the Claymore software.
Download the latest version at the following link: https://github.com/Claymore-Dual/Claymore-Dual-Miner

Once downloaded, unzip everything on a folder on your desktop and open the start.bat file with notepad. Clear the contents and copy the following command:

start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker"
EthDcrMiner64.exe

Where instead of "your wallet address" you will have to put your Ethererum wallet - obviously without the quotes - and instead of worker you will put an identification number in case you build more RIGs (such as RIG1, RIG2, etc ...). We opted for the eu1 pool even if some on the discussion forums believe that the us1 is more profitable.

At the following link, many other useful commands for your Rig:
https://github.com/Claymore-Dual/Claymore-Dual-Miner


The Ethermine pool offers a very well crafted and descriptive interface. In the Payouts section, after only 5 minutes of mining, you can decide the minimum amount of Ether to be transferred to your wallet by simply entering the IP address of the RIG.

We have decided to mine directly on the Ethereum address of our Exodus wallet. It is not recommended to mine directly on Coinbase, as reported on the site itself. Sin.

Nothing should be left to chance when you decide to build a mining rig for Ethereum.
The third variant is the most difficult of all. Once you have reached Part 5 of the guide, you can decide whether to continue or follow this update / variant. If you are here it is probably because you have run into some problem that the guide does not allow you to solve.

With the latest version of Windows 10, you may run into a kernel conflict between the operating system and AMD's Radeon Software Crimson ReLive Edition Beta for Blockchain Compute drivers. This conflict will prevent you from using Atiflash after installing the drivers.

Important: Before making any changes to the BIOS, please backup each GPU.

Important: first of all flash the GPUs with the original bios if for any reason you are forced to reinstall the operating system.


Still on Atiflash.
The advice would therefore be to flash the GPUs and then install the AMD drivers. Let's say it would be because you may run into another problem this time related to the GPUs themselves. Since each video card is different from any other, the bios mod of the GPU could crash the operating system showing the classic blue screen and displaying an error related to the Atimkdag.sys file.

This could be due to the fact that some GPUs have significantly higher performance in the calculation phase than others. We could call it a factory overclock but not using them for gaming we cannot say it with absolute certainty.

Having assessed these two drawbacks, the only safe solution is to flash all the GPUs, disconnect them except for the first one, install the Blockchain drivers (plus Atimkdag patch) and launch the mining command verifying that the operating system does not go into crash in the next 5 minutes.

Turn off the rig again and connect the second GPU so on up to the sixth. In the event that one or more video cards should crash the system, disconnect them. After that, it uses DDU from the provisional mode and flashes these GPUs with their original bios. At this point, connect them again, reinstall the Blockcain drivers (plus Atimkdag patch) and start mining definitively.

All the operations related to the use of Atiflash, DDU and driver installation are reported in Part 5 and Part 6 of our guide.
A little bit of Overclocking.
You will certainly find significant differences in performance between the GPUs.

At this point all that remains is to "operate" with an overclocking software. We opt for OverdriveNtool. Our constantly updated guide is available at the following link: https://www.cryptoall.it/2019/10/12/complete-guide-to-overdriventool/

Link to the official YouTube channel for verification: https://www.youtube.com/channel/UCdE9TTHAOtyKxy59rALSprA

GPUs with modified bios will not leave much room for modification. You will have to proceed with the most extreme overclocking on those that mount the original bios; obviously always in small steps by saving the profile for each GPU. Our guide explains in detail how to do it.

Hoping to have been of help, we give everyone an appointment for the second part of the update on how to build an Ethereum mining rig in which we will explain in detail the dual mining on the Ethermine pool.

See you soon.

Cafe Casino Review

Cafe Casino provides an unrivaled level of service in the online gambling industry. The site hosts a large selection of online casino games including slots, blackjack, video poker, and table games. Boasting a progressive combination of traditional and cryptocurrency payment options, funding your account at Cafe Casino has never been easier. Exciting promotions, free spins, and perks points are just some of the things that await you.
  • Traditional and cryptocurrency payment methods accepted
  • Enjoy a variety of promotions and benefits
  • Available for players in the United States

Cafe Casino Bonuses and Promotions

Cafe Casino has attractive bonus offerings for its new players. There are a few different options available depending on exactly what you’re looking for, but we think most players will find that at least one of these promotions is worth taking.
Let’s start our Cafe Casino review with everyone’s favorite reward: free stuff! When you first sign up for an account here, you’ll get the Cafe Casino no deposit bonus. In this case, it's free chips that you can use in the lobby. You can use this money to play on any game you want, but it does come with some wagering requirements. Also, you’ll only be able to keep a maximum amount from this promotion, meaning that you can’t dream of winning a jackpot while on this promo. Still, it’s a free offer, so even with its restrictions, we imagine many players will want to give this one a shot.
Next up in our Cafe Casino review is a 500% matching bonus worth as much as $5,000. This is a cashable bonus, meaning that you’ll be able to withdraw not only your winnings but any bonus funds left over once you’ve cleared the promotion. In this case, there is a playthrough requirement on the combined bonus and deposit amount, and your cash out will be limited depending on the amount you’ve deposited.
The final welcome offer we’d like to discuss in our Cafe Casino review is their Bitcoin exclusive deal. This massive 600% match bonus can only be claimed when making a deposit through the popular cryptocurrency. Much like the previously mentioned 500% offer, there are playthrough requires as well as cash out limitations.
That maximum cash out clause is a growing trend and not one we’re a big fan of. However, this site gives you a way around it via their No-Max Welcome Bonus, which is also cashable. This version of the promotion only offers a 100% match of up to $1,000 but comes with no maximum withdrawal. As an added benefit, there’s also only a smaller playthrough requirement than the larger offer.
We should note that not all games contribute equally to these bonuses. While all slots, scratch cards, keno, and other “specialty” games count for their full amount, other games contribute smaller percentages of their bets towards your wagering requirement.

Cafe Casino Software and Other Games

Speaking of games, it’s time to take a closer look at what's available to play at Cafe Casino. You’ll find a mix of online gambling games from various providers, most notably Rival and Realtime Gaming (RTG). These two software providers offer up very different styles of gaming
As at most online gaming sites, slots make up most of your choices here. However, the use of RTG software means that you’ll be able to play a great number of table games and other selections as well. For instance, you don’t just have blackjack as an option, but several different variants of the game, including Single Deck Blackjack, European Blackjack, and a version with the Perfect Pairs side bet.
Plenty of other opportunities exist for table game players as well. Barracat, Craps, American Roulette, Tri Card Poker, and Pai Gow are just a few examples of the extensive list of table games available at Cafe Casino.
Plenty of video poker options are offered up as well, including classics like Jacks or Better, Deuces Wild, Bonus Poker, and Joker Poker. Many of these games are presented in a variety of different formats, ranging from single-hand machines to those that allow you to play 52 hands at once. You can also find scratch cards, bingo games, keno and more as you work your way through the software.
Most play on this online casino is conducted through an instant play, no download software platform that you can access directly from your web browser. No special software is necessary; it’s always best to keep your browser up to date to ensure compatibility, however. The site is also mobile-optimized, and easy to navigate on smartphones and tablets. Our Cafe Casino review team found it to work perfectly on both iOS and Android devices.

Cafe Casino Banking and Cashouts

If you’re ready to make your first deposit here, you’ll find that common options are provided for, most notably the use of Visa or MasterCard credit cards. You’ll also be able to make deposits by Bitcoin, a cryptocurrency that offers a level of security and anonymity you won’t find in traditional payment methods. Our Cafe Casino review team finds Bitcoin is a fast and easy withdrawal method, though alternatives are available and are promptly processed.
Our review of Cafe Casino’s withdrawals reveals the same options available as deposits, with the addition of check by courier and bank wire. Bitcoin withdrawals are almost instant, and other methods can take between 4-7 business days to arrive. Regardless of your online gambling needs, Cafe Casino has a payment method that will see your earnings returned to you in a safe and timely fashion.

Support at Cafe Casino

If you ever have any questions when you play at Cafe Casino, the site comes equipped with a detailed FAQ section. Here you’ll find helpful answers to reoccurring questions, such as what countries are restricted, mobile compatibility, and withdrawal times.
Should the FAQ section not have the answer to your inquiry, we recommend contacting Cafe Casino’s qualified support staff. They are available 24/7 on phones, live chat, and email. We found their staff to be professional, polite, and informative whenever we required their assistance.

Our Verdict of Cafe Casino

Our Cafe Casino online review team found that this online gambling site has a lot of incredible elements. With good game selection, great bonus options, and the backing of a well-known network, this casino has established itself as a key player in the market. If you’re looking for a new site to add to your rotation or a place to get started with Internet gaming, we’d recommend giving Cafe Casino a shot.

4 ways to invest in cryptocurrencies

4 ways to invest in cryptocurrencies

https://preview.redd.it/c11khudhmwl51.png?width=700&format=png&auto=webp&s=ebc5ec6628285a889993086971664faddab80830

Investing in crypto is a super popular variant of making money nowadays. It’s pretty hard to avoid hearing about the cryptocurrencies market and its opportunities.

This is an attractive topic for 2020. But how to invest in cryptocurrency correctly? Let’s figure it out together.

1. Deep research.

Conduct a global market research for investing in crypto. This way you can learn more about the coins you are going to invest in and how promising they really are. In 2017, there was a serious drop in bitcoin and altcoins, which led investors to great doubts about the future of the cryptocurrency.
Make a decision carefully, it is better to conduct a good analysis than to lose your Deposit.

2. No hype and noise.

Making decisions during a hype can be risky. It is best to consult with experts and calculate the risks. Often, the price of a coin increases because of rumors. When the wave of popularity subsides, the price may suddenly collapse, which may lead to complete liquidation.

3. Be prepared to lose.

Taking financial risks is an important decision that should be made independently. Decide what you want to invest in.
Investing money in cryptocurrencies should be easy if it makes you nervous. Be prepared to lose what you invested. Invest only free money.

4. Diversify your portfolio.

Splitting investments into cryptocurrencies is a great strategy for reducing risks. There are some difficulties, but this is still a better option than investing in just one coin. Cryptocurrencies are extremely volatile, but it is unlikely that they will fall all at once.
The market is rich in altcoins, bitcoin is not the only cryptocurrency. Study the coins, analyze their potential, and then distribute your finances based on the calculated risk. This will help reduce the probability of losing most of your funds.

Launched in 2019, Unikrn is an online casino, sportsbook and esports site that welcomes players from Canada. Esports is clearly the focus of this gaming platform, however, its casino section features a nice selection of slots, table games, as well as live dealer tables, which you can play using the Unikoin Gold cryptocurrency besides other commonly accepted online casino payment methods. In this Unikrn review, we'll focus on what this online casino can offer to Canadian casino players in particular, by examining the welcome bonuses, game selection and other features that distinguish it.

Unikrn Casino Bonus

Unikrn Casino welcomes new players with a bonus that's made up of two parts: i) a free spins bonus, and ii) a cool deposit match bonus that triples your first deposit amount!

Unikrn Casino Free Spins Bonus

The Unikrn free spins bonus is dedicated to slot players out there, as it consists of 100 Free Spins on Better Wilds slot. The 20 Free Spins are awarded on a minimum deposit of $10 or more, but winnings must be wagered 45 times on casino games before players can make a withdrawal.

Unikrn Deposit Match Bonus - 300% Match

Besides the free spins bonus, new players who deposit at least $10 with Unikrn will also be entitled to a match bonus that triples the deposit amount up to $300.

How to withdraw the Unikrn Casino Bonus

In order to withdraw your winnings generated from the Unikrn bonuses, you need to complete the wagering requirements. The wagering can be completed either on sportsbook or on casino games. If you decide to wager your bonus on casino, you would need to do so 45x, whereas on sportsbook bets, the turnover would be just 3x.

Unikrn Casino Offers - Spend $25 & Get $25

Unikrn Casino runs different offers on its products, with most of them being specific to sports betting. However, it seems that casino players can still claim a bonus of $25 every week if they make over 3 deposits of a cumulative value of $100. This applies to players' first session in Casino every calendar week from Monday to Sunday.
The casino also claims to have ongoing deposit offers for existing players. The best way to find out about such offers as they arise is by opting-in to Unikrn's marketing communications via your profile page.

Unikrn Loyalty Program

We have been unable to find any information on a VIP or loyalty program run by Unikrn for its casino players. Its Connect rewards scheme seems to be restricted to those who play top esports games.

Unikrn Casino Games

The casino selection at Unikrn may not be the biggest one around, but the platform has partnered up with a few leading developers to offer a decent selection of online slots, table games and live dealer tables. Let's take a look at what you'll encounter under each category.
>> Get Your Free Spins Now <<

Online Slots

Unikrn hosts online slot games by the top providers Playtech, Pragmatic Play, Habanero and others. Unfortunately, it does not feature any titles by some of the most loved providers in the slots industry, such as Microgaming, Netent and Play N Go, and we hope that this will change in future. That said, it's certainly worth having a look at its Instant Cash Drop games, which include the popular Pirates Gold and Wolf Gold.

Table Games

At Unikrn you'll find a small selection of classic RNG table games, which include Premium Roulette and Blackjack, as well as Baccarat. However, if you truly enjoy playing these games, we recommend going for the live casino category instead, where you'll find a greater selection of tables.

Unikrn Live Casino

The live casino at Unikrn was launched only this year, but still features some of the most popular live dealer games by Playtech.

Live Roulette

Unikrn sports multiple variants of the popular Roulette wheel, allowing players to take a seat at the following tables:
  • Live Roulette Lobby
  • Live French Roulette
  • Quantum Roulette
  • Age of the Gods Roulette

Live Blackjack, Baccarat and other card games

Blackjack players will be delighted with the selection of variants at Unikrn Casino. As for Live Baccarat, at the moment the live casino only features 7-seat Baccarat.
  • Live Blackjack Lobby
  • Grand Blackjack
  • Quantum Blackjack
  • Unlimited Blackjack
  • All Bets Blackjack
  • 7-seat Baccarat
  • 3-card Brag

Live Game Shows

Those who'd love to try something totally different while leaving everything down to luck can play the below live game shows, which are also brought to you by Playtech:
  • Live Sic Bo Deluxe
  • Spin a Win (money wheel)
  • Buffalo Blitz Live Slots

The choice of cryptocurrencies accepted is vast, and includes all major ones like Bitcoin, Dogecoin, Tether and Litecoin.

Unikrn Casino Site Features

It is super-easy to navigate the casino lobby at Unikrn. Games are divided into categories, under 'Premium Games', 'Top Games', 'Live Casino', 'Most Popular' and 'Daily Cash Drop' games. You can also locate other games by typing the name in the search box. The neat layout and white backdrop give an impression of neatness and clarity, doing away with the clutter that characterizes certain online casino platforms.

Unikrn Mobile Casino

Of course, Unikrn casino is also mobile-friendly and accessible directly from your mobile browser, where games will launch instantly without requiring any downloads. There is a Unikrn mobile app, however this seems to be tailored to its esports product.

Responsible Gambling

Like all other casinos we recommend for Canadians, Unikrn respects Responsible gambling standards and has also implemented different tools to help its customers play more responsibly. These include:
  • Session limits: reminders to make players aware of how long they've been playing
  • Deposit limits: Upon registration, player's accounts will come with set default daily, weekly and monthly deposit limits. Players can decide to lower or increase this limit.
  • Wagering limits: players can also set wagering limits on a weekly basis.
  • Self-exclusion: this can be temporary or permanent, and must be requested through customer support.

Unikrn casino uses SSL encryption to protect its players' identity and transactions. All the games on offer at Unikrn are owned by licensed developers who cater to hundreds of other online casinos. These games have been tested by independent agencies with regard to fair play, to ensure that outcomes are totally random. You can access its full Privacy Policy on its website to find out what kind of data it collects and how this may be shared.

Unikrn Casino Review - our Conclusion

Unikrn's online casino product is relatively new, and for this reason its game collection is not the biggest you can find. That said, we fell in love with its user-friendly platform, and we like the selection of daily cash drop games and its live casino offering in particular. The possibility of playing with cryptocurrencies is definitely one of the main highlights of Unikrn casino, and we think this platform has done a great job of simplifying crypto gaming. And now, why not check out this casino for yourself and claim those free spins?
