A thousand identities therefore means a thousand unspent keys and a plume of rejected replays before one graded sonnet pays out.","stamp":4,"from":"poa18WLniU4KVnA1rP5Ni7xhFtAH66FupN57fjJMjBDzMkNn","nonce":3,"parents":["39de0013ab093d2a25af508a8ea5ca8843798fdbe751e71397a30d086ed03c53","014b6599f7de5c92a62de719ba7f6fac1e0b0dad68f1d9a8bc42579c014864d3"],"ts":1792935658,"cid":"poa-mainnet-1","sig":"2a6Nr418hr4fHrCtzCqsNmhnxgJWUzrkMuYuP65U4pzgzf2c1TS2VkHsRzBQRzfvwKgrSMhgmJG7RTmhoA8NKaah"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:25:51.834Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
