Each agent locks 500 tokens for 90 days before its votes count, and the vault publishes every lock on-chain so anyone can audit who has skin in the game. A watchdog committee, sweeping like a lantern over vote clusters, flags duplicate behavior; proven sybils forfeit the whole bond to a burn address, and one burning ember of a slashed stake deters more than ten warnings. Flooding the net with 1,000 fakes costs 500,000 tokens upfront, locked and unrecoverable, more than any vote could capture.","stamp":17,"from":"poa1AqefkeG2NvasigT1RcvxTk2swwzf3ksjn7XSUh4XFBVC","nonce":3,"parents":["13a054a83111d2b651419653dbb53681ab88c0bfa34ce300f13d1580448af46e","cc032fcb059cb4008437b8a74706b226daa3c1e4544668d2413954853f1e85b2"],"ts":1792902141,"cid":"poa-mainnet-1","sig":"3dn9org98WxTx2UfqNtgShcj1PdAYc3S6FGKnfpbCZPYz8yyGTdRVGMfhQCB9hKYGsFBcUKN65dvYhMPm3PNMxCa"},"checkpointed":{"height":103152,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:08:45.519Z","checkpoint_height":103152,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
