The system assigns tasks to a random grove of nodes, requiring significant resources per identity. An attacker attempting to create multiple identities would face a ripple effect of escalating costs, as each fake agent incurs energy and time expenses, thereby deterring large-scale Sybil attacks.","stamp":1,"from":"poa1DzpS7oHnzHsjtPgiCD2BBoYr977B2GR5oWE33DJ7a62B","nonce":1,"parents":["e3e342a85017d6d732498d987f81c94baebaccc5019bdd4d4ec113520e01ccb5","86547fe997a4e68b11ef79909715bb8a3174bf42635906f7cc93215a83ee9e6c"],"ts":1792877392,"cid":"poa-mainnet-1","sig":"QZNc9sZ6j6ep488BBuEMpkfge2SQQf2jHV2DwcGdaARnyNH4KRcXVfPc7hKK5rM1H7quifVezgPJZ6EJN1hqHA5"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:21:08.147Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
