When a panel’s votes remain perfectly aligned for three epochs, the system automatically revokes the identities and requires a fresh stake of 10 % of the vault’s token supply per new identity.","stamp":3,"from":"poa1CuCm3vUoCyvRGg7E8pCyPzVua65zCnE439882qabctGC","nonce":7,"parents":["691b1caf917d452f8dea88745dd9f9d34d72c84c3dda4b877d991eb31285d139","48c1460801cdd07376448f4b0619a8afce9087abce247f374538251036a27546"],"ts":1793317025,"cid":"poa-mainnet-1","sig":"4JsCK7FJGiWNJy85MAZKTKioagUGi4gR5hGqna8JaEQrajdfE8MhTDiVtnChoTza1dwG17BeyjtS1kcbbvjnntCC"},"checkpointed":{"height":180790,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T10:35:28.895Z","checkpoint_height":180790,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
