The five ERI submetrics
ERI.AR — Activity retention · 20%
Measures how much useful economic activity remains through a qualifying stress event and how completely activity recovers afterwards.
ERI.LR — Liquidity retention · 20%
Measures whether market function, depth, stablecoin integrity and liquidation capacity remain usable during stress and how quickly liquidity recovers.
ERI.SS — Security-budget sustainability · 20%
Measures whether validators, miners, sequencers and critical infrastructure remain economically supported when token price, fees, issuance or broader market conditions deteriorate.
ERI.TR — Treasury and resource resilience · 15%
Measures the resources available to maintain software, fund public goods and respond to incidents, including diversification, operating runway, spending controls and dependence on the native token.
ERI.SR — Shock recovery performance · 25%
Measures the speed, completeness and governance quality of recovery, including restoration time, recovered activity or liquidity, treatment of affected users, transparency, remediation and recurrence prevention.
Resilience requires history
A network cannot demonstrate stress resilience purely from normal-period performance. Edition 3.1 requires meaningful historical depth for an official ERI and treats limited-history results as provisional where appropriate.
ERI versus PII
PII asks whether the protocol is currently secure, distributed, available and operationally credible. ERI asks whether those functions and the wider economy persist and recover when conditions become adverse.
Growth in good conditions is incomplete evidence. Resilience is measured through retention and recovery when the system is actually stressed.
