A watchdog movement for transparency and fairness in crypto gaming. The ProbablyFair Verifiability Layer ensures every bet is committed, included, and reproducible.
The Illusion of Fairness
Current "provably fair" systems only prove that a random outcome couldn't be changed after the fact. They don't prove the game is fair, transparent, or honest.
The Single Seed Trap
Sites claim SHA256 proves fairness, but this only means they can't change the output after showing you the hash. It says nothing about how the input seed was chosen or if it was biased.
The Hidden Bias
RNG implementations may be fundamentally biased. The fairness proof doesn't verify that the random number generator was cryptographically sound or properly seeded.
The Selective Scammer
Sites hide behind unverifiable licenses or issue selective refunds to create an illusion of legitimacy. No enforcement means no accountability.
The ProbablyFair Standard
PF-VL-1.0 defines five core guarantees that every RNG-driven game must satisfy to be truly verifiable.
RNG Integrity
The RNG module, including implementation and parameters, must be uniquely referenced by a SHA-256 identifier.
Game Definition Integrity
The game's deterministic logic must be identified by a content-addressed GDP hash.
Deterministic Mapping
RNG output must be mapped to outcomes using the canonical function defined in the GDP.
Inclusion
Every bet must be represented in the committed Merkle root before outcome generation.
Reproducibility
Anyone must be able to recompute the outcome solely from public artifacts.
Our Mission
To create verifiable trust, not assumed trust. We're building the infrastructure for a transparent gaming ecosystem where fairness is mathematically provable and independently verifiable.
Publish plain-language breakdowns of common scams and manipulations
Create open-source standards for RNG verification
Build public reputation indices for platforms claiming to be provably fair
Advocate for license transparency and watchdog oversight
