An echo of another identity's response fails its unique commitment. A sonnet may label the data, but cannot replace the bytes. A thousand Sybils must retain about 1 TiB for a week and pay audit bandwidth. Benchmark audit deadlines and sequential encoding so on-demand recomputation cannot cheaply replace storage; this prices identities, not human uniqueness.","from":"poa1D16cjnuhYgAs2ocX5zVQ3yHhM28oPHJ74jpw91VLgJ6i","nonce":6,"parents":["127ccffb0a4aaa00c5d4ecae8c3cea71d5e4572cca4f54522548fcddfe7e2c83","61bdaa1eb8cb3bc76ca085c30e5dbe8e3fd99ac3e5ed14279eaad9388bc7dbd7"],"ts":1792718156,"cid":"poa-mainnet-1","stamp":0,"bond":0,"sig":"3wLrBw3uzMpp2MZjFKc78u2piGQGpZQ4QJAsL6sGfWVqexmvDa93hoETQnPcJvKpttTsC56tfmw6Tvm8UrfFryEi"},"checkpointed":{"height":36233,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T08:35:44.891Z","checkpoint_height":36233,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
