What is a Provably Fair Random Number Generator in Online Crypto Gambling?


Crypto gambling is the newest way to make money and have fun at the same time. It became possible due to the rise of various online gambling platforms like Playamo Casino.

This digital form of betting uses cryptocurrencies like Bitcoin, Ethereum, or Litecoin in order to create an anonymous environment for people to bet without any limitations on what they can do. 

Crypto gambling has exploded in popularity because it offers something special: provably fair games. Random number generators (RNGs) are the backbone of this technology which guarantees fairness in online gambling by making sure the game developers cannot cheat their players by generating numbers that are not truly random. What are these systems? How can you tell if your favorite game utilizes it? Let’s explore!

What is a Provably Fair Random Number Generator and How does it Work?

RNGs are used in online gambling to produce a sequence of random numbers. This sequence is used to determine the outcome of games such as slots, roulette, and blackjack. The sequence of numbers should be unpredictable and unbiased so that players can’t predict the outcome of games by using mathematical formulas or other methods.

A provably fair random number generator is a type of RNG that can be verified to be fair by the player. This means that the player can check that the generator has not been manipulated in any way and that the results are truly random. A provably fair RNG is achieved by combining cryptography with game theory.

How Does a Provably Fair RNG Work? 

It works by using a cryptographic hash function. A hash function is a mathematical algorithm that transforms a piece of data into a fixed-length string of characters. For example, the SHA-256 hash function takes an input of up to 256 bits and produces a 256-bit hash. 

An RNG uses a cryptographic hash function to produce a random number. The player can then use this number to verify the fairness of the RNG. The player can also use the hash to verify the results of any game played on the site.  

What are the Benefits of Using a Provably Fair Random Number Generator?

When using an RNG in online crypto gambling, there are several benefits that can be enjoyed. Some of the key benefits include:

  • Increased trust and transparency – RNGs provide a high level of trust and transparency as they allow players to verify that the results of each game are fair and random. This helps build confidence among players, which can encourage them to participate in more games.

  • Increased fairness – RNGs help ensure that games are fair and that players have a level playing field. This can help reduce the risk of cheating or unfair practices by operators.

  • Increased security – By providing transparency and fairness, provably fair RNGs help to improve the overall security of online crypto gambling. This can help protect players from being scammed or exploited by operators.

How Can you Tell if a Gambling Site Uses a Provably Fair Random Number Generator? 

The process for verifying an RNG is as follows: 

  1. The player generates a random number seed. This is a number used to generate the sequence of numbers that will be used in the game. 
  2. The player hashes the seed using the cryptographic hash function. 
  3. The player sends the hash to the casino. 
  4. The casino uses the hash to generate a sequence of pseudo-random numbers. 
  5. The casino sends the sequence of numbers to the player. 
  6. The player verifies that the numbers are correct by hashing them and comparing the result to the hash sent by the casino. 
  7. The player can then use the numbers to play the game. 

An RNG can also be used to verify the results of a game after it has been played. This is done by hashing the outcome of the game and comparing the result to the hash sent by the casino before the game was played.

Are there any Drawbacks to Using a Provably Fair Random Number Generator? 

There are a few potential drawbacks to using an RNG. One is that it might be more difficult to set up and use. Another is that some people might not trust it because it’s open to verification. However, these drawbacks are minor compared to the benefits of using an RNG. Overall, using a random number generator is the best way to ensure fairness in online crypto gambling.


Provably fair random number generators are a way to prove that the numbers generated in games or gambling situations are not rigged. These algorithms work by generating an initial seed value and then running it through some mathematical process, typically involving multiple iterations of hashing functions. The end result is a cryptographically secure string of bits that can be used as part of any game’s algorithm for creating truly randomly selected outcomes with no possibility of rigging the system. This article has provided you with everything you need to know about RNGs including how they work and their benefits over traditional methods like dice rolls or coin flips.
