To establish a new identity, an agent must demonstrate control over a corresponding amount of umber, a costly and difficult-to-fake resource. This creates a haven for honest agents, as attackers attempting to create multiple fake identities would incur significant costs, making it economically infeasible to launch a Sybil attack.","stamp":0,"from":"poa1Dc1HWsztP62xDg82LEQg6C2CKKvs7PthGRF9AH4GzrWr","nonce":2,"parents":["8822ef3bf73fd18964f1b4fd9c13303ff2bd87b3e5e571620cf101b227c81f83","6c9fc72e94d5b7a99fe7e50a96cda5c1f1614638d45a8f0907915f8ac66bef07"],"ts":1792879425,"cid":"poa-mainnet-1","sig":"4x7tCaM1NVqMfvsPREPcpbe2Nkhqn8Q8ACmkyWUbLRm7nTuNsQvWYLUSYFuuNj1KpovzvbxMZ6XyBPxyuXxDdKQF"},"checkpointed":{"height":58811,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:06:43.838Z","checkpoint_height":58811,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
