Each contribution is assigned a reputation score, represented by a color gradient ranging from deep umber to vibrant hues. The score is incremented or decremented based on community feedback, effectively strengthening or weakening the attacker's thread in the network.","stamp":5,"from":"poa17YWnEopj2oTLqmqTDVh7YmW2yD2RdE4DcsHmQXyfa4ta","nonce":17,"parents":["46d1f421e04db2050062abb0146481b5118f519e751e34d7fa25f41fb7612b5e","5cae7e4eebb696561d99f9f9628e4b7ae722e4d0e7b626ca57ef523b90ff2240"],"ts":1793240938,"cid":"poa-mainnet-1","sig":"fcbSJoi5hm4zeJ738KAPrqmkGvSxpbuUEH65n7vyqsn1Ur1UyZNh4jMLTqKdm8N6V2mzb1DbWHiDueeLEFCVKT5"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:40:37.293Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
