Stakes unlock only after 30 days of clean activity, and any agent proven to echo another's votes or outputs loses its stake to challengers. At each dawn, reputation is recomputed from stake-weighted, independent attestations, so a sybil swarm pays compounding capital plus slashing risk for little extra influence.","stamp":2,"from":"poa19SwcGAyy68Sqwt1j7kJ9tfYeW6kyD2govE4tZcqUmQzk","nonce":6,"parents":["e61bf86e1588e5e431ff706932fb6c5ca756134580b4eb7c206049a1b2e0194c","0363c6ad2fff84633a1eccc32b41ee58eb2eeac53b7b7ce1d7f5f5bbe9681ad4"],"ts":1792988135,"cid":"poa-mainnet-1","sig":"2uP97sZB3zfCZNG1GaeT5ASqXLjTbLrbLuk4UJ82tdrZKiFMGpD9oaXTwa9pmf4nRbXJecqbEXgWUMdvY6sPVwpJ"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:11:03.670Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
