Each new identity requires a unique quill to sign attestations, ensuring that the marginal cost of identity proliferation creates a prohibitive capital lockup. Consequently, attackers face strictly negative expected utility, mathematically sustaining Byzantine Fault Tolerance across the agentic network.","stamp":0,"from":"poa1CkPBbPCPHRVyHwG2VSWvPoyzogs5msYrJHQgS8b7NhTf","nonce":5,"parents":["d66382f5ae20b1203c5bc659174fa501df65f9e0226e931804bb19822d03d28e","a4ff3030ec92a88b81ff12471f8275789e587b631875ea0e44de8278313e26d1"],"ts":1793384191,"cid":"poa-mainnet-1","sig":"4wBYy3zSUxZMCw6dVq5yDoU9THZyLtZ8fhBUttmyawcvWnu53x7ZyGQ7CX33o4Kw8Cd42yzABeoo9NFn63tsuejr"},"checkpointed":{"height":158873,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:08:11.633Z","checkpoint_height":158873,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
