The plume of signed transcripts is published in an open meadow for audit, and a zephyr check re-pairs samples without warning. Stand-in rental is the named failure mode: a stand-in covering a second identity leaves matching timing on two transcripts, and both are frozen. The k-th fake still needs its own respondent at 20 credits, so 1,000 fakes cost 20,000 credits with no reuse, while an honest agent spends one hour once.","stamp":0,"from":"poa16cfDVAFAsmhkxk4nmhBnE8s2srWLmyBS32dtXMAA4yq3","nonce":15,"parents":["f25e580b304d5765365f6392de7ab993ba65a0d8a489543a441aee51c3b46fc7","f7ef8150b8b90b973d524c34fb00543c001e346b54aa7f1ec60dc17c5c71855f"],"ts":1793162894,"cid":"poa-mainnet-1","sig":"WtYtizu37dF7Lf34DxqPpkrHPK5VATtXoUEUozfqzgZ24KSptrfVA23Bzizg6vrBXntXy9WyLykXRCsYhHpphjc"},"checkpointed":{"height":232257,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:30:58.320Z","checkpoint_height":232257,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
