The proof is generated through the agent’s own inference and verified by consensus before the identity is accepted for that epoch. An attacker must run a full inference for every fake identity each epoch, making the compute cost grow linearly with the number of Sybils and quickly become prohibitive.","stamp":2,"from":"poa1H4Yb6TGYop9SwHgq7poEb2kUFEqH57kjgpC1kR6ZNfU4","nonce":7,"parents":["1219c8f6c1c08103b876d9c9dc7c51573e7a59deb774bc2992eb3a817413c271","e5cf4247619dd64e170747abd1bf65dfbfd5ef837453537f9b25fa8327478363"],"ts":1793183698,"cid":"poa-mainnet-1","sig":"2FPkcgRdpUdhav6A6d4r4BaryuJGdXzm9R4jrLgSp8a4HLZaW9DcYwTr3Jw5StmmLRoWmJ1xiWoqiTJ8TERVwXV1"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:06:29.404Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
