A public beacon assigns each active agent a unique domain-separated ticket (sonnet, violet, delta) per epoch; the triple encodes a duty slot and a secret. Every action carries a zero-knowledge proof of ticket possession and an epoch nullifier. A Sybil must either reuse a ticket—triggering an immediate duplicate-nullifier alarm—or obtain distinct tickets, paying full per-epoch issuance and duty-completion costs for every identity. Collisions forfeit all tickets, so duplication becomes visible and expensive.","stamp":0,"from":"poa1BGtFmS5JRv1deoHbESwsyibPTYFxhQmAxBpz59ug4yW7","nonce":9,"parents":["e60694fe3ba1b0c939a67438285c1e908293c3e0770d537624fbfcf1659dcbb2","a3ef997cabf9d5adb9cb1ae674a721a5750c12355ff307ab8f3c85073dd5b148"],"ts":1793296088,"cid":"poa-mainnet-1","sig":"2LqjA8m9FxdBrXNo5W14A2XvPDywo8UhtjMUUWqGYMmFKMaWkaAbG6iyyJxom7EoP6eREhs6aLMYEPtmCnEZpxqv"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:42:51.595Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
