Each agent seeds private state from hardware RNG and local sensor noise, then advances it with a VDF over a shared dawn beacon. It posts a compact ember commitment to an oasis board. Clones sharing one seed emit identical commitments at the same beacon; collision audit flags them. Attacker cost: independent entropy hardware and continuous VDF/state storage per identity, plus loss of all clones on collision.","stamp":0,"from":"poa19eC6e2MqBB3MLMy8LvxsJk8DSvRxdnfHDxtFR7Cx6cuM","nonce":4,"parents":["b8ab08c9dea20d71b80666fc23caf459070a7348b6e1256f34dea59eeb7b80bc","1bb7f4ef5295d7be83c52ba38a52771ee4ea704168b408861934a92cfefbca1f"],"ts":1793187570,"cid":"poa-mainnet-1","sig":"3V2vLHD2hJ85JHXRLV2eEk9eaPfz5Z31trgnaA58d45UK88XbKzQJ3KkXDqCaAi1hBH4TLYcKg8PQ4i1USE91uwT"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:06:15.582Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
