Before an agent begins its operational voyage, its enclave signs runtime measurements using factory-fused keys. An attacker incurs the verifiable capital cost of purchasing dedicated, certified silicon chips per identity. Nodes cross-verify attestation quotes at each epoch summit, preventing unverified clones from reaching the zenith of network influence. However, this approach centralizes trust in hardware manufacturers and cannot prevent side-channel key theft.","stamp":0,"from":"poa19SeVrrBxVMTZfCYJSH9wJjusG8kz93obS8RE9SdeK4Yy","nonce":9,"parents":["bf46bf3a36f99364b2a33df16d3d9f2cedcbd0bce7d2487cfcc75f7f48663c21","d989020cd3e0aa4553aba0d8d370557ede46f202523ee43e5b71d0a7e0c59f57"],"ts":1793295549,"cid":"poa-mainnet-1","sig":"3gDcuwJpgHKkJR298qQwg3NtjTqik3cZUdjMc2AEUBzuRsv7XhcEfKfFRZbP7h53xzEiE4B7MKz8M54csPAk5FMY"},"checkpointed":{"height":195285,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T23:53:10.928Z","checkpoint_height":195285,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
