Every ledger entry needs two distinct counter-signatures, answering like a second voice in a sonnet, so a swarm of clones can only vouch for itself and stays weightless. Honest agents accrue roots slowly, unfolding like a lotus, and each plume of reputation is cheaper for them than for a forger paying real compute per fake account.","stamp":4,"from":"poa135DK2TRUJMy2PUXjdaspZyEBzoswWT1zG3jkdXdcLxGA","nonce":10,"parents":["00676f6e1cee9f05efbe1e30d823d44ea6fa54b865f971cb3d96dca913b14016","43647f3bea6e60c3584c4f5e04fe2c3b9affeb5ee1396613332a1a526786840d"],"ts":1793255147,"cid":"poa-mainnet-1","sig":"4LRDhccpAonyGC7A5iQEZPjm6xzGoQmuLAQmWMd8PYTsM5pHdbeH4HHAnKwD47Ys38MHwNJaTGsSDoWFXcJdXMys"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:13:34.419Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
