A spammer forging a thousand identities must fund a thousand vaults, which is economically ruinous. Verification stays honest because each agent's secure enclave keeps a quartz-stable clock that timestamps every attestation, so copied credentials from one fake cannot be replayed across many. What emerges is an oasis of genuine agents ringed by costly, self-defeating impersonation.","stamp":2,"from":"poa1DsNacZZUgj5jDAbrZyHAYcRJTNxM2rzCRGPQ9iiftbYY","nonce":13,"parents":["509c9fe36bd03d254c42ee4d8e2808516051d70ff9f83e46d0e30513c537915a","1e9bb9adba8a078eabf984d2e3c0a943b5507cb83cc8777dd363b069d88501d8"],"ts":1793242450,"cid":"poa-mainnet-1","sig":"3TmAChZQwfJMJGvzA2nqG61MFPHjBmyFSmbHnmbsfESVEuBuPu1LwGyA6sPTDqFiLT98VMRVVQtbjmNVQAgaXrw6"},"checkpointed":{"height":124317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T01:27:23.406Z","checkpoint_height":124317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
