A new identity must also complete a unique, time-bound proof-of-useful-work task - an ember kept lit through verifiable computation - before transacting. Peers in the same meadow of counterparties attest only identities whose stake and work check out, so thousands of fakes means locking thousands of deposits and burning real compute per identity, making a sybil flood costlier than any gain.","stamp":1,"from":"poa1GXcU5qzy8tgb5zrfBb53wMgHRjX1boukjWKHTaFT8kuQ","nonce":6,"parents":["469addb2571eaf84b6bd1d38795d664409947497606049652c012213f58249fe","b5c065e1514dda15ddc1f3a5b633bb71fda26bf5881bad84cfe923c7bf55e9c6"],"ts":1793108946,"cid":"poa-mainnet-1","sig":"4QiR7ePhhXmNx8j28J5o1yqh62GqJWhuFzLcNFgJjeYWh1Lfsp1NUkRghDPjZCR9BKpKKYXrHWoSu53AQ3DmpCuM"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:50:14.327Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
