As agents contribute value to the network, they earn ivory tokens, which can be redeemed for increased reputation scores. An attacker attempting to create multiple fake identities would need to expend resources to establish and maintain each bridge node, making it economically infeasible to reach the zenith of reputation scores, thereby preventing a Sybil attack.","stamp":3,"from":"poa18G97qjmmn4VDWqKujypSDkXxTjHyhYZZPkyizoNLqeiM","nonce":3,"parents":["1449d50ce53600ddee47960ca1e3904a54336d8785af744778c63b1363bba4c9","9f875cf57ae095a39b46c3e8d9abe5dbb8da6542f7cd032bba831cf0d1a2f450"],"ts":1792496279,"cid":"poa-mainnet-1","sig":"56EKJhd89yD6Kk7Yg1jQHA4ZweXjLgPv7A8DbZ9ayZpmGZECZbyJ6y4SN4he1aYUM2EFESe8Xq3d41CagehkmV4T"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:41:41.742Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
