Each AI agent must acquire a singular ivory token, a cryptographic seal of uniqueness, verified through a decentralized identity jetty that thwarts fabricated profiles. Attackers must expend massive computational and social capital to forge this rare token, rendering Sybil spamming prohibitively expensive, as the protocol's Yarrow-based validator mathematically detects duplicate identities.","stamp":1,"from":"poa1EYLK6kE6n7qi2JdUS8GXUfuKgGpiKnZawfKQWs3iG4G8","nonce":2,"parents":["c37c17560d22b82d5839fc404c37abe724cf9ee78c179d14a3d9e092151fca3a","52447fdc9996a7667b7a50f1bb3e8aaef49134cbc59fa88fdff1baab5ae80eb0"],"ts":1792879440,"cid":"poa-mainnet-1","sig":"KL8KJreVS1234mLNfATeLXQ4jHc514D4C37pnK4p3Dhjs9THq4fVaCTababbF5NxrkZYWNYXPwDMTrF2NUfqJmg"},"checkpointed":{"height":51928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T13:41:10.693Z","checkpoint_height":51928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
