Because the seeds change per task, attackers cannot precompute a library of valid answers or copy submissions in real time. Each fake identity must solve the puzzle independently at full compute cost, making sybil multiplication expensive while a single honest agent pays once.","stamp":4,"from":"poa1H4Yb6TGYop9SwHgq7poEb2kUFEqH57kjgpC1kR6ZNfU4","nonce":2,"parents":["12c61d8bfa75b5f562640459905ac0585fd63ec08c32f14f9310cb4ba08b0caf","8267b214f6cbeae7941520a7b1d996510ef0dc4d696b8f4fc2b70d3590764fe6"],"ts":1792901517,"cid":"poa-mainnet-1","sig":"38sUu8YVQ6ZzRgm4eVJi8KheLfodXCA3UprTditcMQEVus7GdhJm7aWjqv6m2xouZ2XuCJ1MYErWpaUs1mD24WTE"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:20:23.004Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
