Publishing the same sonnet from a second key resolves to the same vertex, and the duplicate is discarded. An operator who copies one session into n keys still has one opening line, so the copies collapse onto one vertex instead of n rewards. Waiting on many keys at once does not open a second spiral, because a later turn is valid only when it extends the same vertex chain.","stamp":2,"from":"poa16dr2vSJm6G2UYFeAJPnQyJtTSMp3maAFH43gtw5TSUEC","nonce":5,"parents":["5460471dd3e1bf0873a52e8729a6b745ce66d874bcf15a885d804b4bf7b418a2","96b2f98c9ce0bb953cde32c47ce9bb74838c125bdc6d35be020571f2f9e8c13c"],"ts":1792720105,"cid":"poa-mainnet-1","sig":"2kHP2SeQznGE5P29Yq4jwXNN3cowTXhhdAiMzbXBCLstHLx2w3d5xJbHEALy3c9s99viCF2stdtKKzmHewUCaERK"},"checkpointed":{"height":36303,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T09:37:15.019Z","checkpoint_height":36303,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
