Introduction

RandProof Network documentation: Proof-of-Fair-Randomness (PoFR), the universal on-chain standard for verifiable, tamper-proof randomness.

RandProof Network is decentralized, permissionless infrastructure implementing the Proof-of-Fair-Randomness (PoFR)™ standard across 17+ blockchain networks. Every PoFR event produces a RandProof, a permanent on-chain proof artifact, verifiable by any party at any time.

Any industry. Any chain. Any selection. Proven fair by math.

Three Ways In

Integrate RandProof

Add verifiable randomness, automation, compute, or oracle data to your contracts in four steps.

Run a Keeper Node

Operate infrastructure, stake, and earn 70% of network fees as a keeper node operator.

The Three Layers

The documentation and whitepaper are organized around three layers:

Layer 1: RandProof Core: the protocol itself, EntropyAttestation, KeeperCoordinator, RandProofRNG, Automation, Compute, Sentinel, Forge, Oracle, Identity, Audit, and Custody Proof, plus the keeper network that operates all of them. Any party can integrate Layer 1 with no prior relationship to the RandProof team.
Layer 2: Production Deployments: real-world usage of Layer 1. The genesis client is BIT5050, a multi-chain Web3 raffle ecosystem spanning 17+ chains.
Layer 3: General Market: everything Layer 1 can serve, DeFi liquidation triggers, DAO governance, AI inference verification, supply chain, reserve attestation, and more.

Network Properties

Chain-agnostic, 17+ supported networks: Base, Optimism, Arbitrum, Linea, Ethereum, Polygon, BNB, Avalanche, Moonbeam, WorldChain, HyperEVM, Solana, TON, Cardano, Sui, Polkadot, and Bittensor.
Ten chains live, KeeperCoordinatorV8 is deployed on Base, Optimism, Arbitrum One, Polygon, Linea, BNB Chain, Robinhood Chain, and Arc (USDC-native fees — the first dollar-denominated deployment), with the V8A variant on Avalanche C-Chain and HyperEVM (chains without the EIP-2537 BLS12-381 precompile — the drand anchor is committee-attested rather than verified on-chain). One committee, the same 12 keepers, secures every chain.
No token required, clients pay per use in USDC via the x402 micropayment rail. No governance token, no LINK-style dependency.
Transparent economics, 70/20/10 fee split: 70% to keeper node operators, 20% to the network treasury, 10% to the gas reserve pool.
Entropy at scale, designed to aggregate fifteen independent entropy sources across seven entropy domains, targeting a $100B+ attack cost at full Phase 4 deployment.
