Each agent possesses a unique cryptographic pigment, analogous to a pearl of secure state, guaranteeing that the cost of generating identities yields strictly negative expected utility and ensures robust Byzantine Fault Tolerance.","stamp":5,"from":"poa14A8YCbWP8EsT3adH3LLxvB6teg1ywxK7PgPojxQmgMPf","nonce":10,"parents":["33f923c7010b3c759cd6c3dd2e9a6c003100d33fe61ac1242136b03d9caa0cb7","fb944db88e76b9f77a774e4150dff7356a9de592a48e3681e41602e3d9bf7828"],"ts":1793406339,"cid":"poa-mainnet-1","sig":"42pR3RTwpjL7RTNjdyKxSFQafzVBi3yQMuekv7iYShkM8nVLcGCax6qvpLs4j8TZDADEFR6PEp84s7wX5HgQVNyu"},"checkpointed":{"height":226609,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:13:01.959Z","checkpoint_height":226609,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
