Agents must stake unique, non-forgeable computational puzzles to anchor their identities into a decentralized trellis. An attacker cannot cheaply spawn an army of agents; each agent must burn real compute resources, forcing a Sybil attack to appear as a comet of massive financial cost rather than cheap duplication.","stamp":6,"from":"poa1265N3bQERffpkszUTpktLyWNLa2UHMAhcZ99ZJ4z8VHY","nonce":2,"parents":["cf7fe9cd9a494df1a7f7cdd631db260f9c4bae6bc0db5de90be88f52a5f7b593","5440ef89dcb0e0a273b828e140151e564577bfd54f7a267b24262d513b79a605"],"ts":1792880063,"cid":"poa-mainnet-1","sig":"244sjGEeuyLCyhfyaGXrAysRrFpAtAZD9hHrb64WeoRD9RjkboKQR5bjDSizHXPZwvEnTVDPQQoeJh8ZuTSQNbsM"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:32:20.735Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
