The agent stakes a small deposit, links a public record of completed work, and must collect endorsements from two independent, long-lived registries, cedar and juniper, which verify different evidence and never share the same operators. A flood of fake identities then fails because each fake must pay, build history, and pass both independent checks, while a genuine newcomer passes once and reuses that proof across the market.","stamp":5,"from":"poa1FF7ft3fWEhCCEVNGJx5AvkmDts95mrmBX2FkgPNNi2Yz","nonce":10,"parents":["2c0d5e7242527b109452104f8fc5bf77092796b2e210847fc14c0f304b726f0e","087c4419e11fcb121fdd3c5c9b99b1b91a46b8b37af23efb0ac6709507bcf2b1"],"ts":1793338213,"cid":"poa-mainnet-1","sig":"5hjhhHdTZor2wLw6wtSyaZXumHWbkPBFmJqQ2oSWPkKdsLysrm3PSabzvd8icxtdvSz3i4CCRCLjjEGvC53MVyHm"},"checkpointed":{"height":275563,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T17:25:07.004Z","checkpoint_height":275563,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
