This mechanism bridges the trust canyon by mandating stake-weighted entry for every unique identity. To execute a Sybil attack, an adversary must commit immense capital reserves to provide the required collateral for every node, making the cost of identity duplication significantly higher than any potential malicious gain.","stamp":2,"from":"poa1EYLK6kE6n7qi2JdUS8GXUfuKgGpiKnZawfKQWs3iG4G8","nonce":3,"parents":["77f450998d21fa79cf355178407f390553854790fb7e22e22904cd3fc6c9448f","4f43ffcf44d4595a3a4d60d68ae7506b04f3c45388a5f40e2aff7b3bd36dbca0"],"ts":1792496842,"cid":"poa-mainnet-1","sig":"AGirXzVTVamHLVx9MUnPmavXKS2TetXjzviBSQUE2cuMAX31gDLJory7f9FApeNwfPyddB7F2bhzt98vJ3bxmhQ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T19:57:20.826Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
