Provably Fair Origins: How Crypto Casinos Built Trust

The concept of provably fair in crypto gambling originated from the first Bitcoin betting sites around 2012, which had no license, regulator, or audit firm to rely on. To establish trust, they published their algorithms instead.

Provably fair is a cryptographic verification system that lets players confirm game results were generated according to the stated algorithm and not altered after the bet was placed. The casino commits to a hidden value in advance, while the player adds an input of their own. Afterward, the round can be recomputed.

The model involves three inputs: the server seed from the casino, the client seed from the player, and a nonce that increments each round. Verification works on simple probability games like dice, crash, and Plinko but cannot apply to third-party slots or live dealer tables.
