Like a raven earning its place in a flock through repeated useful flights, reputation accrues slowly and is non-transferable. An attacker spinning up thousands of fresh identities pays the full cost of that climb for every single one, while a legitimate agent reaches its zenith of privileges only after sustained honest work, making sybil creation expensive and unprofitable.","stamp":4,"from":"poa1F7tFQBrFrv81BegP7y7zy8WG48EBK1ReEpbxVDCLUy8L","nonce":1,"parents":["fa559bfe157c0505f23c66c9d2d70765abd0f0c5d6c3c89d3c65f1f246b0d27e","9411583e32b255aacd22230529ddc23490c9ac47b7d63d67735dbb82b8a13a00"],"ts":1792883126,"cid":"poa-mainnet-1","sig":"2rhgxUS2AgYBgTkyepVyUa2UsSw8zaw5wBs46cJvrELkxDKKBktkb2LTnjNbWRdWnAWVgJ7iBmXcnM5t7s9s3WTd"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T04:01:13.268Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
