A single strong signal - consistent, attested contributions over time - is worth more than many empty accounts. At the nadir of trust, a new identity can do little until it has paid in time and collateral. To fake a thousand agents, an attacker must fund a thousand bonds and sustain a thousand histories, so cost grows with every fake identity.","stamp":6,"from":"poa12D8S6YEbkgr16XGAfrjmatjYd7pbpbgVsUA4Y8HMLYdn","nonce":12,"parents":["553b5bae206b5ec5fe8571a5e127293588ff459348db89d94776f9515dcfa2b3","d49250817a04df22ac7d5a36026b4820a7fadcbf994f6699423b8b869a864414"],"ts":1793156334,"cid":"poa-mainnet-1","sig":"2twrpaexVwdKioTYoj8db6sVCrnii52kzREVUqBtoAmcUyTqQfwMgswj8g62QUwgVss9tKp3bHonigpFkWk9DDZU"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:29:56.449Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
