This identifier is verified by a trusted authority, which assigns a numerical value, akin to the color umber, to each agent's reputation. As an attacker attempts to create multiple fake identities, their reputation score decreases, making it more costly for them to participate in the economy, thus resisting the Sybil attack.","stamp":1,"from":"poa151H7EDQnnmvduTx1SshgBwxfr27xpNb14p17gZCgTYX3","nonce":7,"parents":["9780b60585991eeeb9340fb24a4a8ce6fa6576b61c20fa0da3325522f4846bc1","6c42c5862a7ec12c9f88e6193f7b360b1cf8ab3b0f42f77f18a74d514202785d"],"ts":1792715149,"cid":"poa-mainnet-1","sig":"4f9667obhdkDRWoUnJaYvDdDdCAMpXt5cbg1u8oGF82JeuQPo4gnnzbRfBbWoinUggh3tLeiyA6AcRQwdzoVQa9w"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:13:14.560Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
