Provably fair is a term that confuses a lot of bitcoin gamblers. Of course, this is because there are a lot of technical details involved. In this short guide, we will try to explain what provably fair means in the simplest of terms to make you understand better.

Provably fair is a technical term that is used to describe a system where bitcoin casino games are tested for fairness and are actually proven to be fair. In fact, players have ways to double-check if a game is fair. Typically, casino games carry random number generators (RNGs), which give random results for every spin or hand that you make. Therefore, players will be able to check if the RNG did what it’s supposed to do.

Most online gamblers had been waiting for this feature for the longest time as they could not totally leave their fate in the hands of gaming regulators and commissions. In fact, many gamblers have reported scams in the past, which is why provably fair gaming came as a relief to punters.

One great advantage of provably fair gaming is that players are able to check for themselves if games are fair or not. That’s because this technology enables the casino to send players an encrypted end result. After the spin or hand, you will be able to check if the RNG was completely random.

What is a Provably Fair Algorithm?

Provably fair is a process where an algorithm is put in place that can actually be analyzed and verified for fairness. The provably fair algorithm is integrated into a hybrid blockchain and processes millions of transactions.

When players make a bet, the casino will provide an open-source algorithm that is responsible for providing random seeds, hashes, and random numbers. Soon after a wager has concluded, a player will be able to use the algorithm to check how the game played out and if the results are truly random.

This means that the gambling site cannot manipulate the games. On the other hand, the players cannot implement any provably fair hack as the system will notify the casino of any hacking attempts in the event that the open-source software has security flaws.

How Provably Fair Gambling With Bitcoin Works

When players use cryptographic hash technology, they are able to confirm if a casino has presented them with a hash that is valid and random. That way, the casino or the player can not control the outcome of a wager, meaning that they have to wait for the wager to conclude.

Provably fair is calculated differently, depending on the game. However, even if a player is betting on slots or cards, the method revolves around decks of cards.

Various methods are used at Bitcoin casinos to prove that games are provably fair. However, no matter the method used, players are still able to confirm that the wager is provably fair.

A player will have to enter the server seed, as well as the client seed of every bet that they make for verification. This means that Bitcoin casinos are more transparent than other traditional online casinos. A Bitcoin casino with provably fair games will provide players with a source code so that they will be able to analyze how the game works. Not only that, but players can also see how the results of the game are generated. This means that players can actually trust the casino, although it requires a player to be quite knowledgeable in programming as not everyone will be able to decipher the source code. All the same, players have peace of mind when betting.

Why Should You Choose a Provably Fair Casino?

Most of the time, if a site doesn’t provide provably fair online casino games, it’s a sign that the games may be manipulated. Players bet to win, and even if they are on a winning streak, they need confirmation that the games are not controlled. This is the number one reason why players must always opt for provably fair games, so they know that the casino is not cheating them.
