The Role of Provably Fair Gaming in Crypto Gambling

In the world of online gambling, where players are often skeptical about the fairness of games, provably fair gaming has emerged as a solution to this problem. Provably fair gaming is used by online casinos to ensure the fairness and transparency of their games. It is a method of verifying that the outcome of a game is truly random, and has not been tampered with by the online casino or any third party. The system allows players to independently verify the fairness of a game by checking its cryptographic hash and seed value. In this article, we’ll take an in-depth look at provably fair gaming, its role in crypto gambling, its advantages, and limitations.

What is Provably Fair Gaming?

Provably fair gaming is a term used to describe a set of cryptographic algorithms that ensure the fairness of online casino games. It is a system that allows players to verify the fairness of games, and it works by using complex mathematical algorithms that are virtually impossible to hack.
In traditional online gambling, the outcome of the game is determined by a random number generator (RNG) that is controlled by the online casino. The problem with this system is that players have no way of verifying that the RNG is truly random, and that the online casino isn’t manipulating the results to favor the house.

How Does it Work?

Provably fair gaming works by using cryptographic algorithms and blockchain technology to ensure that the outcome of each game is truly random, and cannot be manipulated. When a player starts a game, the online casino generates a random seed value, which is then encrypted and sent to the player. The player can then use this seed value to verify the game’s randomness.

The emergence of cryptocurrencies like Bitcoin has made provably fair gaming possible. Since cryptocurrencies use blockchain technology, which is decentralized and transparent, it’s much easier for players to verify the fairness of games. Many online casinos that offer provably fair gaming only accept cryptocurrencies as payment.

How do I Verify that the Games Played were Really Fair?

It is important to note that the specific steps for verifying the fairness of a game may vary depending on the online casino and the game in question. However, most online casinos that offer provably fair gaming will provide detailed instructions on their website on how to verify the fairness of their games.

To check the fairness of an online casino game using provably fair gaming, you will need to follow these steps:

Step 1: Check the game's cryptographic hash - The cryptographic hash is typically provided by the online casino before the game begins. You can copy this hash, and use a hash calculator to verify that the hash matches the one generated by the online casino.
Step 2: Check the game's seed value - The seed value is usually provided by the online casino at the end of the game. You can use this value to verify that the outcome of the game is truly random by inputting the seed value into a random number generator, and comparing the result to the game outcome.
Step 3: Check the game's random number generator - You can use the seed value provided by the online casino to verify that the random number generator is truly random by inputting the seed value into the same RNG used by the online casino, and comparing the result to the game outcome.
Step 4: Check the game's payout percentage - The payout percentage is displayed on the online casino's website. You can compare this percentage to industry standards to determine whether the game has fair odds for players.
