Analogy
Proof-of-Trust is like a credit score for network nodes—consistent good behavior and endorsements increase your trust rating, which then grants you more responsibilities.
Definition
A consensus or reputation mechanism where nodes earn influence by accumulating trust scores derived from historical behavior and peer endorsements.
Key Points Intro
Proof-of-Trust secures networks by:
Key Points
Reputation scoring: Aggregates performance and feedback.
Endorsements: Peers vouch for reliability.
Adaptive weighting: Trust influences consensus power.
Sybil mitigation: New nodes start with low trust.
Example
A decentralized oracle network uses Proof-of-Trust to rank data providers; high-trust nodes have their feeds weighted more heavily in aggregate price oracles.
Technical Deep Dive
Each node maintains a trust vector updated per epoch: trust_new = α·trust_old + β·behavior_score + γ·peer_endorsements. Consensus algorithms sample proposers weighted by trust. Misbehavior triggers trust slashing via on-chain governance votes.
Security Warning
Collusion on endorsements can inflate trust maliciously; require diversity in endorsement sets.
Caveat
Initial trust bootstrapping is challenging; poor initialization can centralize power.
