provably fair casino

Perhaps only the most desperate people can decide to play for money in online casinos. It is impossible to check the outcome of a “random” event, the probability of winning inherently in the algorithm is unknown, it is not clear who is behind all of this, and in general, will the winnings be given back? There is too much uncertainty, do you agree? After all, online casinos are virtual at their core, these are just bits and bytes on some remote server that can be simply manipulated to fit the “randomness” into your business plan.

With the advent of cryptocurrencies, freedom has come unprecedented. Now you can easily transfer any amount from point A to point B, the bank is not able to block the account at the request of the clerk, and transactions are public and irreversible. The revolution was supposed to come to the world of gambling because, with freedom and anonymity, with crypto appeared new opportunities for fraudsters of various stripes. The casino works with chances and probabilities, and question is, how could gambling sites show their own transparency and convince gamblers of the independence of random processes? The answer to this question is given by cryptography.

Minimum Foundations of Cryptography

Bitcoin technology is based on cryptography. It ensures the impossibility of forging wallets and transactions. Cryptography is the science of hiding information using ciphers. One of the side effects of the development of encryption algorithms was the invention of hashing functions (hash functions, or simply hashes).

In simple terms, a hashing function is a kind of digital signature. The original text is not entangled, as in the case of encryption, but undergoes a series of irreversible cryptographic transformations, the output of which is another text, often also called a hash. Basic properties of hashes:

  • the original text cannot be obtained from the hash
  • for the same text, the hash will always be the same
  • the slightest change in the original text will entail the calculation of a new hash
  • hashes are also unique for two unique texts

Thus, we can say that the hash “signs” the source text, uniquely identifies it. And the main further of bitcoin casino provably fair that you can check hash. Hashing is at the heart of Internet security. For example, the service in which you store your correspondence stores your password, as a rule, in the form of a hash. It is impossible to get the original password from the hash, which means that when the server is hacked, your password will not “float away” (another thing is that hacking the server usually automatically means free access to your correspondence, bypassing your password, but this has nothing to do with cryptography). When you enter a password to access your mailbox, the server calculates a hash from the entered password and compares it with the hash of the original password in its records, and if the hash matches, you are given access, if there is no match, the entered and original passwords are not equivalent.
