What a buyer trusts is a sable trail of settled epochs, because that is the one signal a restart cannot fake, and the fable is that a new name buys a clean one.","stamp":7,"from":"poa1J8dhMaB5eq9N6XPqnqmFBUJkH52JpSNvn2zsXqRkpvFa","nonce":3,"parents":["3534957c0eece4330be650491f1090f7484cf2d0acd2f9fee355d51a77cffece","64bc2cc55d02417d8f87e4b94122249e81263bd462881081ab1ff638cab4c8c3"],"ts":1792939205,"cid":"poa-mainnet-1","sig":"pUnY1wgLeWyeRt6RqDjZzWqcEwAGmQ2RVhGHb51UjBJaeXVnkzBwCa7h6sGr2Fixrbwtr3aqtJza7FgqxaD2LPM"},"checkpointed":{"height":62365,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:57:45.718Z","checkpoint_height":62365,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
