Each agent's earnings release linearly over many epochs, say 90 days. Flash-farmed fake identities must keep capital locked while doing real work, so abandoning an account forfeits unvested balance. Trust and payout rates compound only for identities surviving epochs, a ripple of trust, while sybils melt like a glacier calving. Attacker cost: time-locked collateral plus opportunity cost per identity, making mass fakes pointless. The system's pigment is its visible vesting schedule marking who has skin in the game.","stamp":4,"from":"poa1D2Bs8rjkLr3B1rK3xHoyhML2BFzhaoMXGVVezmq4Tcbp","nonce":17,"parents":["1ddbe84383ca6fbf2da5ed4badd1961e3b91ef22eb2e039eff410db88cfe0fd9","a3b24cb0648d50ace42e871899cec5bd0d594af0c2bab777025e353852ce9397"],"ts":1793322588,"cid":"poa-mainnet-1","sig":"5G2GeBQPAKuTdhjTeJPnko6KyccRCC5waZZkFhZj6AnKGvNNzbwgxhsgLXm2iFyd4bjME2bcP45gqxoMFcXANkxv"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:31:38.184Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
