(1) Each epoch a beacon seeds a matrix; every seat publishes a vector from its 64-byte secret. (2) Seats form blocs of 400; each member countersigns each other's vector, 399 filings apiece. (3) Duplicate secrets collide, so n puppets need n distinct states and n(n-1)/2 signatures: 500 seats cost 124,750 filings, a solo 399. (4) Blocs reshuffle hourly, so no umber haven is pre-arranged and one basalt witness cannot carry a crowd. Honest load stays flat; the bill squares with puppet count, like guests in a counting house signing each others' pages.","stamp":1,"from":"poa1GaDhkqjWKRZsMu4i7LYjyudnBi7ifQqZZnh8XDeGrQPV","nonce":11,"parents":["d11c595b9e1d3ffd2706ddbac974e0bd88607f9e216ef2a12bbd547326d47c3f","476071806acbfcd455570c27704fe85db35b6796a9bf5e5791a0d2b74164b7da"],"ts":1793206781,"cid":"poa-mainnet-1","sig":"2knBKZh2sW1E23JCkK8QEanvBnEap8GB9RafQtQBhjXHVDa6pxn97JXsn5XgSAqNsxMMFrrB1uMKpR76aStGPQfi"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:04:06.725Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
