Provable Fairness in Online Gambling: Ensuring Fair Play

Online gambling has gained immense popularity, but concerns about the fairness of games have persisted. Provable fairness is a technological solution designed to address these concerns by ensuring transparency and fairness in online casinos. In this article, we will explore the concept of provable fairness, how it operates, and its significance in the online gambling world.

Understanding Provable Fairness

Provable fairness is an algorithmic system that verifies the fairness of online casino games. It is predominantly used in Bitcoin and cryptocurrency-based casinos, offering players assurance that they are not being cheated by online gambling platforms.

How Provable Fairness Works in general

Provable fairness relies on three key elements:

1. Server seed: Provided by the online casino.

2. Client seed: Generated by the player's browser, often adjustable by the player.

3. Cryptographic nonce: A number that increments with each bet placed.

The process begins with the online casino generating a seed number, which is then hashed and shared with the player before they place a bet. Hashing involves converting a lengthy data string into a shorter one, making it difficult for either the operator or the player to manipulate the seed.

Simultaneously, the player's browser generates a random client seed. Players are encouraged to modify this client seed before placing bets. Once both seeds are in place, they interact with one another to produce the outcome of the bet. The cryptographic nonce, which starts at 0 or 1, increases with each bet, and the algorithm uses these seeds and the nonce to select a random action within the game.

After completing their gaming session, players can receive the unencrypted version of the client seed and verify the game's fairness. This verification involves inputting the unhashed seeds into a verifier, which checks if the outcome matches the one displayed in the game.

YummyGame's Unique Multiplayer Game Fairness System

YummyGame has implemented a unique multiplayer game fairness system that enhances security and fairness compared to standard fairness systems. Here's an overview of how their system works:

1. Secure Server Seeds: YummyGame generates server seeds in advance and stores them securely using the AES algorithm.

2. Public Server Seed Disclosure: They publicly disclose the last server seed on the Bitcoin community and their forum, ensuring transparency.

3. Salt Value Enhancement: To further enhance randomness and fairness, YummyGame designates the hash value of an undisclosed Bitcoin block as the salt value. This salt value is also publicly announced in the community and forum.

4. Random Number Generation: When the specified Bitcoin block is generated, YummyGame uses the pre-created server seed and the block's hash value (salt) to generate the random number used in the game.

5. Sequential Seed Disclosure: YummyGame discloses their server seeds sequentially. For example, if they pre-created 100 server seeds, they publicly reveal the 100th seed first. The 99th seed and salt value are used for the first random number.

6. Immediate Disclosure: The random number and server seed used in the game are disclosed as soon as the game ends, ensuring transparency.

7. User Verification: Users can independently verify the fairness of the server seed by hashing it with the pre-announced 100th seed.

8. Random Number Verification: Users can also verify whether the correct random number was used by hashing the disclosed server seed and the disclosed salt value.

This system provides an added layer of security and transparency, allowing players to verify the fairness of the games they participate in.
