RandProof6. RandProof Network: Architecture Overview
RandProof Network is a standalone, permissionless, decentralized keeper protocol implementing the PoFR standard across 17+ blockchain networks. BIT505
6.1 What RandProof Network Is
RandProof Network is a standalone, permissionless, decentralized keeper protocol implementing the PoFR standard across 17+ blockchain networks. BIT5050 is the genesis client, proving the protocol works at production scale across 17 chains.
6.2 Network Mission and Positioning
| Dimension | RandProof Network |
| Mission | Universal cryptographic fairness proof |
| Protocol standard | PoFR™ (coined and owned) |
| Revenue model | 20% protocol fee from every PoFR event |
| Node operators | Anyone who stakes earns 70% of fees |
| Token | None, USDC or native assets |
| Clients | Enterprises, governments, DeFi, DAOs, gaming |
| Chains | 17+ (EVM + non-EVM) |
6.3 Five-Layer Architecture
| Layer | Component | Function | Trust Model |
| 1: Application | Integrating contracts | Emit PoFR requests, receive outcomes | Smart contract logic |
| 2: Coordination | KeeperCoordinator.sol | Stake registry, BLS verification, fee distribution | Immutable on-chain |
| 3: Randomness | RandProofRNG | 15-source entropy aggregation, BLS threshold signing | Cryptographic |
| 4: Automation | RandProofKeeper | Event detection, signing, fulfillment | Economic incentives |
| 5: Computation | RandProofCompute | Off-chain computation with on-chain proof | Multi-keeper consensus |
6.4 PoFR Event Lifecycle
Contract emits DrawRequest(eventId)
Keepers detect event via RPC WebSocket
Each keeper fetches all 15 entropy sources: DRAND round, NIST beacon, chain-native VRF, commit-reveal XOR, block timestamp, Ethereum RANDAO, Bitcoin Merkle root, multi-chain block hashes, ANU QRNG, Tor consensus hash, BABE VRF, drand Quicknet, RandProofVRF, Autonomous Beacon, and Epoch Entropy Pool
Each keeper computes M = keccak256(eventId || drandRound || **nistBeaconValue ||** blockVRF || **block.timestamp**)
Keepers generate BLS partial signatures σ_i
First keeper with t=3 signatures aggregates: σ_agg = σ_1 + σ_2 + σ_3
Keeper calls KeeperCoordinator.fulfill(eventId, entropyInputs[15], entropyBlock, σ_agg, signers[])
Coordinator verifies BLS aggregate on-chain (BN254 pairing) against M = keccak256(abi.encode(chainId, address(this), eventId, entropyInputs[0..14], entropyBlock))
Coordinator verifies on-chain entropy sources (Layer 1): DRAND BLS sig, PREVRANDAO opcode, block.timestamp, RandProofVRF, Autonomous Beacon VDF, EpochPool contract
Coordinator verifies multi-keeper attestation (Layer 2): at least 2 independent keepers submitted matching values for off-chain sources
24-hour challenge window (~43,200 blocks on Base) opens (Layer 3): any keeper or observer can submit fraud proofs for unverifiable sources
If no fraud proof after 10 blocks: Coordinator calls back IntegratingContract.fulfillRandomness(eventId, seed)
Coordinator calls back: IntegratingContract.fulfillRandomness(eventId, seed)
Contract computes outcome = uint256(seed) % totalEntrants
Coordinator distributes fees: 70% to keepers, 20% to treasury, 10% to gas pool
RandProof stored on-chain, permanent, public, verifiable
No Centralized Path: No party can control, delay, or influence outcomes. No admin key on fulfill(). Four-layer entropy verification ensures submitted values are independently verifiable, not just signed by 3 keepers. Fraud-proof challenge window allows any observer to invalidate fabricated entropy.
