Provably Fair

Provably fair is the future of gambling and every casino that is not provably fair will eventually stop working. You should not trust every site because many of them are not provably fair and they manipulate bets’ outcome. In the simplest way possible, we will explain what the provably fair system is and how it works.

You hear the term Provably Fair here and there, but you are not really sure what it means when it comes to online casinos. We will explain everything to you before you start gambling.

Most of the players think that they can be cheated on an online casino, they are right in most cases. It is, technically, very easy for an online casino to “cheat” on you.

That is why in the Bitcoin gambling world we have a solution called “Provably Fair”. When the casino is provably fair, it allows you to verify every single bet, to make sure you’re not being cheated.

“Provably Fair” system provides a way for both the casinos and players to contribute to number randomization, which removes any possibility of cheating (explained below).

You can use our verifiers as an easy way to verify your bets:

How Provably Fair algorithm works?

There are a several Provably Fair methods, we will describe the most common one.

With this method, each result is determined by these 3 variables:

1. Server seed (provided by the site)
2. Client seed (provided by your browser and adjusted by you)
3. Nonce (A number that increases with each bet you make)

You will get an encrypted hash of the server seed from the site in advance, so there is no way for the site to change it afterwards. It is, however, encrypted and you cannot calculate your own roll results in advance (only after you change your seed).

As far as client seed goes, your browser will generate a random client seed. You can adjust your own client seed if you want to make sure the site does not know your client seed in advance.

Nonce is the number which increases by 1 with every bet you make. Nonce can either start from 0 or 1, it depends on the website.

Bitcoin Casinos

Beginning right from ancient times, humans have actively participated in gambling, one form or the other. The adrenaline rush that one gets when gambling is like none other. This is the reason that even kings and monarchs used to challenge odds and try their luck. To this end, Dice was a popular gambling game that both Romans and Indians have played throughout history.

There are numerous tales where fortunes were made or lost during gambling. While a good gambler is the one who knows when to stop, you do need to start somewhere. Earlier, you had to travel all the way to a casino hub to try your luck. However, the current internet age has made it relatively easier to do that.

All you need is an internet connection and some bitcoins to your name, and you are good to go. Yes, bitcoin casino is the latest take of the gambling world. Also, if you like to play the odds in the game of dice, you can even go ahead and gamble on bitcoin dice or try your hand at blockchain poker.

What are the pros and cons of playing at provably fair bitcoin casinos?

It is true that bitcoin dice and blockchain poker has got a new makeover because of various bitcoin casinos. They bring along many benefits like quick transactions, transparency, etc. However, some might argue that it has taken the thrill off the game. While it is for you to decide whether this bitcoin culture in the world of gambling is good or not, let’s look at some of its pros and cons.

Pros of playing at provably fair bitcoin casinos

Quicker transactions

You might get lucky and win a fortune in no time when luck turns in your favor. But you will need more than luck to withdraw that fortune when you are playing at traditional online casinos.

Most service operators take up to a week to transfer your winnings to your account. It is also provided the casino doesn’t put a halt on the transaction claiming faults in your winnings. On the other end, they won’t take a second while processing your payment.

Bitcoin casinos have changed the way the transactions were traditionally taking place. The fund transfer, whether you are receiving or sending the payment, has never been quicker. All you need to do is link your account, and the transactions will happen in a matter of minutes.

Safety of funds

When you want to start playing on one of the online casinos, you need to input your debit or credit card details. All of us know how risky it can be, considering all the cyber threats that we currently live under. The websites might store your data, or a hacker might break into your account.

When you play through bitcoin casinos, there is no such threat. All you need to do is link your account with your bitcoin wallet, and you’ll be all set to play.

Privacy and security

Most of the players who are involved in casino games prefer to be anonymous while cruising the online casino world.

This decision is very well understood. However, you need to clear the know your customer (KYC) and other legal requirements before you can start playing. This process can be long, and you might end up losing the will and interest to play.

However, there are many bitcoin casinos US that just need your email account and a bitcoin address. Once you provide these details, you can start playing right away.

Clarity and transparency

There is a saying, ‘House always wins.’ It is a fact when it comes down to the traditional online casinos, which have an edge. Also, because these casinos operate on private networks, there is not much that you can do about it in case the casino chooses to rob you of your money.

However, bitcoin casinos are empowered by blockchain that offers a transparent record of transactions. This ensures that you will never get cheated.

Cons of playing at bitcoin casinos

Bitcoin Volatility

Bitcoins are volatile and undergo extreme daily changes in their value. This volatility can be attributed to the low supply and ever-increasing demand for bitcoins. Many players prefer using money over bitcoins because of their easy availability.

A new form of currency

Bitcoins are the currency of the future. It was just recently invented. So, it is yet to take its final form.

Untraceable

One of the biggest controversies around bitcoin gambling is that the source of the funds is untraceable. Some people argue that bitcoin casinos are the most convenient way of laundering money and illegitimate channel funds.

There are both pros and cons of using bitcoin, just like two sides of the coin. However, we believe that its pros outweigh the cons.

Is bitcoin gambling legal?

The legality of bitcoin gambling hasn’t reached a final verdict yet. There are various schools of thought and opinions around this. Here are some points regarding bitcoin gambling that you must be aware of.

Neither legal nor prohibited

There are no specific governing rules around bitcoin gambling. While there are no laws that legalize this aspect of gambling, there are no criminalizing laws either.

Same laws as online casinos do not imply on bitcoin casinos.

Technically, bitcoins are not a currency. Yes, it is a medium of exchange and has properties similar to another currency, but still, it is far from it.

Because bitcoins are not a currency, the rules governing online casinos that transact in money do not apply to it. But, the world of bitcoin is rapidly advancing and taking a new form every day. We are still to find out what various governments decree about it in the future.

Be cautious of the country-wise laws and accepted practices.

In countries like the USA, where gambling is a crime under law, authorities might not take kindly to bitcoin casinos as well.

So, if you are planning to visit a bitcoin casino US or any other for that matter in the countries that frown upon gambling, it is advised that you remain cautious at all times.

Anonymity is the key.

The world of bitcoin casinos prefers to stick to the shadows and place high weightage on anonymity. And, various tools like Thor have helped this new world of gambling to make their activities and transactions even more anonymous than before.

Regulatory bodies

In some countries like the United Kingdom and Curacao, there are regulatory bodies that are issuing licenses to bitcoin casinos as well. These bodies claim to regulate the functionality of these casinos. So, if you are looking for a safe place to try your luck, you might want to head to one of these countries.

Bitcoin Casinos – what is the key takeaway?

In the world of gambling, bitcoin is the new arrival that has already made space for itself. More and more thrill seeking gamblers are making their way to these casinos to try their luck because of the many benefits that it offers.

However, whether it is through money or through bitcoins, you are still gambling. So, it is advised that you be careful when playing against the odds and while choosing the casino to play at.

Additionally, we need to wait and see how governments respond to this new culture of bitcoin casinos. Till then, you can head to one of the few who have already obtained some license.

WANT TO WIN $7500?
IT’S NOT TOO LATE!

HOW DO I PLAY BITCOIN LOTTERY?

“What is bitcoin lottery? How to play the lottery? How to enter the bitcoin lottery?”
These are some questions that might be racing through your head right now. We’ll answer them all.

What Is Bitcoin Lottery?

The FreeBitco.in Bitcoin lottery is a provably fair online lotto that takes place every week on the FreeBitco.in website. Where 10 lucky users stand a chance to win up to $7,500 in free bitcoins every week.

How to Play the Lottery?

Entering the lottery is easy – all you need are one or more lottery tickets that make you eligible to participate. There are several ways to get yourself those lucky tickets, and once you do, the system automatically enters you into the draw.

What Time Is the Lottery?

Every Monday, the weekly lottery starts at 00:00 UTC. All the lottery tickets you earn or buy after that are eligible until the lottery ends on the following Sunday at 23:59 UTC. The provably fair system picks 10 winners at random and the corresponding BTC prizes are directly transferred into their FreeBitco.in wallets.

Where to Buy Lottery Tickets?

You can choose to earn or buy your bitcoin lottery tickets on FreeBitco.in. There are 4 ways to get your hands on them:

FREE SPINS

On the Free BTC page, you get free spins for free bitcoins every hour. All you have to do is solve the captcha and hit roll. For every free roll, you get 2 lottery tickets. These lottery tickets are automatically added to your ticket total and you’re entered into the draw.

FREE SPINS BY REFERRALS

FreeBitco.in has a comprehensive referral program, and one of the benefits of referring your friends to the website is that you get 1 lottery ticket for every free spin your referrals roll on the Free BTC page. The tickets you earn from your referrals are automatically added to your ticket total and are eligible for the draw as well.

WAGERING IN THE BITCOIN DICE GAME

The Multiply BTC page takes you to the in-house HI-LO dice game, where you get 1 lottery ticket for every 1000 satoshi bet or 0.00001000 BTC you wager on the game. This is the easiest way to get a massive amount of lottery tickets on-the-go.

BUYING LOTTERY TICKETS

If you’d like to add to your ticket total further, you can buy lottery tickets on the lottery page on the FreeBitco.in website. A ticket costs 1 satoshi or 0.00000001 BTC, and there are no limits to the number of tickets you can buy.

How to win the Free Bitcoin Lottery?

Once you start accumulating lottery tickets, you can check your ticket total on the Lottery page on the FreeBitco.in website. Here’s how it looks:

The ‘Your Tickets’ section, of course, tells you your personal lottery ticket total. The ‘Total Tickets’ section tells you the total number of tickets that are actually in the pot, and the ‘Win Chance’ section calculates your chance of winning in the bitcoin lottery. To have a better chance at winning, accumulate the highest number of tickets possible for you during the week. The higher the number of lottery tickets you have, the higher your chances of winning the bitcoin lottery.

How Does Bitcoin Lottery Work?

This lottery is provably fair. What that means is that there is no way the site can cheat you by picking a lottery winner who we favour. All winners are picked randomly and the method for picking the winners is described below.

1. At the beginning of each round, we generate a server seed for that round and show you the SHA256 hash of this seed.

2. When a lottery round has concluded, we make a list of all user id’s and their lottery tickets and sort it in ascending order of the user id’s.

3. We then use this list to assign ticket numbers for all tickets. For example if user id 1 has 10 tickets and user id 2 has 20 tickets, then user id 1 will have ticket numbers 0 to 9 and user id 2 will have ticket numbers from 10 to 29. This is done for all users.

4. Then the list containing the user id’s, tickets held by each user and their ticket numbers is published in a text file. This file also contains the total number of tickets issued in the round and the server seed for that round.

5. A MD5 hash of this text file is calculated.

6. Then the current bitcoin block number is recorded and a block number that is 12 blocks into the future is decided on. The block hash of this future block is used as a “client seed” ie. a seed that we are not aware of when the list in step 4 has been published.

7. Then a tweet is made via our twitter account (https://twitter.com/freebitco) containing the link to the file generated in step 4, the MD5 hash of the file and the future bitcoin block number as determined in step 6. Since tweets cannot be edited, only deleted, this will provide a timestamp for when the list in step 4 was made, which can be compared to check that the bitcoin block determined in step 6 is in the future ie. we do not know the block hash of this block when the list is generated.

8. The winning ticket numbers will be calculated as described below:

A string (STRING1) is created – “[SERVER SEED]:[BLOCK HASH]:[WINNING POSITION]”.

The SHA256 hash of STRING1 is calculated and the first 8 characters of this hash are taken (STRING2).

STRING2 is converted to a decimal which gives us a number between 0 and 4,294,967,295 (NUM1).

NUM1 is then multiplied by the (total number of tickets minus 1) and divided by 4,294,967,295 to get a number (NUM2) between 0 and the total number of tickets less 1.

NUM2 is then rounded off to the nearest whole number which is the winning ticket number.

The [WINNING POSITION] starts at 1 and is increased by 1 for picking the 10 winners. The user having the ticket with the lowest [WINNING POSITION] wins the first prize and so on.

If a user wins more than 1 prize, the number is discarded and [WINNING POSITION] is increased by 1 and the calculations are run again to pick a new user. This is to ensure that a user cannot win more than 1 prize in a round.

A string (STRING1) is created – “[SERVER SEED]:[BLOCK HASH]:[WINNING POSITION]”.

The SHA256 hash of STRING1 is calculated and the first 8 characters of this hash are taken (STRING2).

STRING2 is converted to a decimal which gives us a number between 0 and 4,294,967,295 (NUM1).

NUM1 is then multiplied by the (total number of tickets minus 1) and divided by 4,294,967,295 to get a number

(NUM2) between 0 and the total number of tickets less 1.

NUM2 is then rounded off to the nearest whole number which is the winning ticket number.

The [WINNING POSITION] starts at 1 and is increased by 1 for picking the 10 winners. The user having the ticket with the lowest [WINNING POSITION] wins the first prize and so on.

If a user wins more than 1 prize, the number is discarded and [WINNING POSITION] is increased by 1 and the calculations are run again to pick a new user. This is to ensure that a user cannot win more than 1 prize in a round.

How is the system Provably Fair?

The system described above that is used for picking the winners is provably fair because it has multiple safeguards in place to ensure that winners are picked randomly and fairly.

1. We provide a SHA256 hash of the server seed when a lottery round starts. If we change the server seed at any time, the SHA256 hash of the new seed will not match the hash we provided earlier. After a round has ended and we provide the server seed that will be used to pick winners, the hash of the seed we provide can be checked against the hash we provided originally and both should match.

2. We use a future bitcoin block hash as the “client seed” ie. a seed that we do not know of. All bitcoin block hashes are unique and nobody knows what the block hash of a future block will be until the block has been mined.

3.We use twitter to publish the future bitcoin block number, the list of users and their ticket numbers and the MD5 hash of the user list. It provides a timestamp to check if the block hash that we use is indeed in the future. Since tweets cannot be edited, only deleted – if we delete the tweet after the future block has been mined and publish a new one, it would be easy to catch us cheating by comparing the timestamp of the tweet and that of the bitcoin block. The timestamp of the tweet should always be lesser than the time timestamp of the bitcoin block whose hash is used as the client seed.

4. We provide a MD5 hash of the text file containing the list of users and their ticket numbers. If even a single character in the text file is changed after the MD5 hash in the tweet is published, the MD5 hash of the edited file will not match the MD5 hash provided in the tweet.

How do I check the Lottery Results?

At the end of the week, at 23:59 UTC on Sunday, all your lottery tickets will be entered into the draw. The process mentioned below will determine 10 random winners, with the top winner earning up to $7,500 in BTC.

Scrolling down on the Lottery page, you’ll find the leaderboard that shows the top 10 winners of the week. Currently, Lottery Week Number 258 is in process, and below you can find the leaderboards for all previous weekly lotteries with their corresponding winnings. Scroll through them and see what you are in with a chance to win every week!
