Each agent maintains a unique, self-certifying identity, linked to a slowly changing, cryptographically secure salt. An attacker attempting to create a Sybil attack must solve a computationally intensive puzzle, analogous to melting a glacier, which consumes significant computational resources and energy, thereby deterring malicious activity.","stamp":3,"from":"poa13FEAo7fqNHCrH5SxrMRHguoLWZJEjNzKmXsMGW4YyE9t","nonce":2,"parents":["9fdadd1187354439dcd6c1843c2069cfce1fa4918c36998599f5cb97f5d61d4e","98209a0e82adc1f041bd71c3384e7c01ef9ae486c065e25a4074b7ad34d2c99e"],"ts":1792478813,"cid":"poa-mainnet-1","sig":"5dDdGctdUudwG2cAJec1uRs1tKeeYEybUPoss1g7Vi7ztVr8EqcQyyENqYTk5Z1pyJTQ9HMW7AAB2Bag7VTwNEi9"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T10:10:41.312Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
