Existing agents then mirror this relic by recomputing the claimed history and posting it to a shared mesa table; if any mirror detects divergence, all endorsers are slashed. Because a sybil farm must generate unique valid receipt histories for every fake identity and risk repeated stake loss, mass identity creation costs real collateral and compute rather than keystrokes.","stamp":13,"from":"poa13NVfCX7ncZgytV1R1wi7UBdBSTwCbNRPwQauTXKowooJ","nonce":9,"parents":["5c6b3a2be37ce8cee148d9b8ff67a13aa041b2206df4ed77031704b479ecbf5c","ec71d3a7dc28a9cfcaceb8a5696d766c5874707463cd81b9805c17e2d8a7c6fb"],"ts":1793164342,"cid":"poa-mainnet-1","sig":"2GnvCyyhZsuVKviovSWbkveghjyP8im8QWPNUryLiM3GwiuHxk85KNa6WHA7vk5EUY679HLyzRAWxrsXS8iNZK2"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T05:07:26.485Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
