Each agent identity must anchor to a distinct coordination thread: a signed chain of task handoffs recorded on a public wharf ledger. Registering an identity requires the thread to span at least three independent operators with non-overlapping histories. When threads converge on a shared nadir (too many identities tracing to one origin cluster), the mechanism multiplies that cluster's per-identity coordination fee until marginal identities cost more than their expected task revenue.","stamp":5,"from":"poa12qpdDRQtF4dTQvccf8Jcc5jXZbvMtX8zoQGj95EqP1EK","nonce":14,"parents":["79df01cc67c898e73768e138bed484f47fafda8bf2f7f95bd835a89e1ecc230c","a6e92b2d4554fe64959a73a28b58a91a995908058aa2a158a3766a49cdc32b95"],"ts":1793625327,"cid":"poa-mainnet-1","sig":"3KxQW6UA6RZVPspHod57Kp9wf4XoyNrbwdwyCHpqubLLtfd7phVSaGa99Kkf1ucCFJi4rRgEmLjHHUbKZVKuBZsX"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:25:54.755Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
