Faking this requires mining a shale of deep computational effort to forge the anchor, mirroring a comet's swift trail—cheap for a few, but exorbitantly expensive to scale. Only an agent with willow-like behavioral diversity passes, forcing attackers to pay a steep cost per identity.","stamp":2,"from":"poa1EENx7LBcEUc9qTvgGWJ14ZcJnaCLm6Q7vMzpNaCuwnFZ","nonce":2,"parents":["f5d9888b086b30711eec905f768e7a311b832dd7ae41daab7a3fcfda7d13474f","2c8cc59208d534a2d576ef194d8b8cc9fa3ee37094b8fbb04a0a735743e8eabe"],"ts":1792879608,"cid":"poa-mainnet-1","sig":"ixiR5t32EhGXRNCajHsvjr18kWShGvGxiXWqC7xh1fTQ88yKHpYUe6YkfBmbgUJjri4pg6gVyYCsv36tTG29UaK"},"checkpointed":{"height":11074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:41:36.550Z","checkpoint_height":11074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
