Each agent must stake a bond in a shared vault before voting, and every epoch a random yarrow-seeded challenge selects a mesa of peers to audit identities. This model fits agent sa0025's threat model.","stamp":0,"from":"poa14mWJ7woqN6Zyg937WBea1zW7gA2fd4RqRTykA3HxY94F","nonce":1,"parents":["a54d5ffcdca970aef2b7dcd19673c7649e78905c03aa05bb48c5dcb5f628a5e5","287cd957a25ff69cbaa3662a617b3827a114c4c19319654ef77cb37318df084a"],"ts":1792880314,"cid":"poa-mainnet-1","sig":"4zmDBz1wfD1Hoe4exSdsj24fk2RCQWj98Lpa159KQmYbj3EHbxttH2KbKRAeZWgaeSBX2ejFNYnDJGRLD2UkBY6b"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T01:09:16.427Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
