How honest are bitcoin casinos and online casino games? With provably fair games, crypto casinos have become game changers in ensuring the randomness of each bet’s outcomes. Read on to discover how the provably fair technology works and explore the top 10 provably fair casinos. Here are the provably fair Bitcoin casinos that you won’t want to miss!
In traditional online casinos, bettors cannot check the randomness of the game outcomes. Since most casinos need access to the source code of the games they offer, they cannot confirm unbiased results. To address players’ concerns about being cheated, reputable casinos reach out to independent testing laboratories to audit their Random Number Generator (RNG) software.
Crypto casinos have reimagined the gambling experience. In a provably fair game built with Blockchain technology, you can verify the randomness of each outcome and rest assured that the game is unbiased. Since provably fair casinos store all information about gaming sessions on the decentralized ledger, all results are public and thus easy to check. So, there is no need to rely on the certificates of verification from third-party testing laboratories anymore.
Does it mean that provably fair casinos offer only provably fair games to play? Not necessarily. As a rule, the selection of games in a crypto casino includes custom-made titles built on top of the provably fair algorithm and popular games from licensed providers.
Let’s see how the games referred to as provably fair work. Here are the main components that determine the fairness of the results:
Before the game starts, a gambling site generates a server seed, hashes and encrypts it, and sends it back to a player. After that, a Bitcoin casino cannot interfere with the server seed or change it in any way.
The browser generates a random string known as the client seed on a player’s side. Together, the server seed and client seed produce the result of the gaming session. To prevent an online gambling site from seeing your client seed in advance, you can modify it before making a bet.
Along with the two seeds, a provably fair algorithm uses the nonce — the value that reflects the number of bets made. With each subsequent game session, the nonce number increases by 1.
By the end of a provably fair game, players get their initial client seed which they can use to check if the game was honest. The verifier feature in the game interface enables you to compare your initial seeds with the actual bet’s result. Getting the matching values means no manipulation of the game outcome.
Random number generation — aka, producing a sequence of numbers that is hard to predict reasonably — is essential for online casinos. To generate random numbers, the online casino software has a built-in RNG that replicates the processes in a physical casino.
Why do RNGs in provably fair games give players more peace of mind than traditional online casinos? First, provably fair Bitcoin casinos ensure random game outcomes through the cryptographic hash function. When hashed, seed numbers undergo an unbreakable encryption process preventing any manipulation of the data strings.
Second, with the provably fair algorithm embedded into a crypto casino game, players can easily double-check if a bet is fair. Blockchain technology and smart contracts bring transparency to casinos: stored in a decentralized ledger, all transaction records are public and thus easy to verify.
