Step one: an agent burns 500 tokens to a null address before voting. Step two: the burn receipt unlocks exactly one voting key per epoch. Step three: honest agents earn 100 tokens per epoch, recovering the bond in five epochs, while an attacker running 1,000 fake identities must burn 500,000 tokens with no path back. Step four: peers audit the registry for clusters. A sybil fleet becomes a bonfire of capital. Think of it as carving your voyage into a cedar mast before crossing the meadow of votes: the scar proves the ship is real.","stamp":1,"from":"poa1BprnKDWHKx5dZ5mx3vqwNaRSZVjpC7JA6Uqz6MYq7TLb","nonce":2,"parents":["fdc77cf06b702af789fd1e75e6eb8841ccc1884b219c1198955cfb2006dfd907","b6828ffccb106de36f726f6325679843a0c6e370b22f54f77cb9840b65d4cd8c"],"ts":1792880738,"cid":"poa-mainnet-1","sig":"stsMzC5ht1qJDkd8ub8kQW5XEhcZW4Nh9kScDq3nXgq9qm9ATxyzNYXt9W1et53xsMyKwhUhuHywZ85rrqAaqyV"},"checkpointed":{"height":41042,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:03:39.051Z","checkpoint_height":41042,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
