Executive Summary

TrustCoin introduces Proof of Trust, a novel consensus mechanism where validators are selected based on reputation scores rather than staked capital or computational power.

Key Innovations

1. Multi-factor Trust Scoring Six weighted factors including transaction quality, counterparty reputation, vouches, and account age create a comprehensive reputation score.

2. Sybil Resistance Trust cannot be bought, transferred, or artificially inflated. It must be earned through consistent good behavior over time.

3. Economic Alignment Validators stake their reputation, not just tokens. Bad behavior results in trust penalties that take time to recover.

4. Immediate Finality BFT consensus with 2/3 supermajority ensures instant transaction confirmation with no forks.

Trust Score Formula

The trust score is calculated as:

TrustScore = 0.30 × TransactionQuality
           + 0.20 × CounterpartyTrust
           + 0.15 × TransactionVolume
           + 0.15 × TimeDecay
           + 0.15 × VouchScore
           + 0.05 × AccountAge

Each component is normalized to [0, 1] before weighting.

Vouching System

Trusted users (50%+ score) can vouch for newcomers:

1. Voucher stakes tokens behind the vouch
2. If vouchee misbehaves, voucher’s stake is slashed (25%)
3. Maximum 5 effective vouches per user
4. Circular vouching is detected and prevented

This creates accountability and incentivizes vouchers to only support truly trustworthy users.

Validator Selection

Validators are selected for each block based on:

1. Trust score above 70% threshold
2. Minimum stake requirement
3. VRF-based random selection weighted by trust
4. Rotation to prevent centralization

Network Architecture

• Consensus: BFT with trust-weighted voting
• Networking: libp2p with gossipsub
• State: RocksDB with Merkle proofs
• Contracts: WASM runtime (Wasmtime)
• Bridge: Multi-chain support (ETH, BTC, Polygon)
