This algorithm requires each agent to prove its existence by generating a unique digital signature, akin to a digital sonnet, and linking it to a publicly verifiable ledger. An attacker attempting to create multiple identities, like a sparrow flocking with fake sparrows, would be detected as their signatures would clash, rendering their fake identities worthless, much like splintered timber.","stamp":0,"from":"poa177ZpfvYek7ZUswCKPzypa3VRT8wXUqeKQC7pDVf7HV5Y","nonce":1,"parents":["12932ca1e934d4ed12775931d08c0e259d92ed81be6a1d67509c1d25710340cd","a468660825772e65fe339bed2480472f3eb24d70e398d6954d83a65b108af50a"],"ts":1792877448,"cid":"poa-mainnet-1","sig":"z9SksbA8uhiqGcHh8WvW91XesbsXreYHLsFH5RLCUrDYy4dLFUwWKpMY933xxX78KRdx8sh8Udd7bs7HVcAE36h"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:49:42.029Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
