Reputation is non-transferable, grows only from attested work, and decays when idle, so a hollow identity with no history carries no weight. Paper ivory credentials or self-asserted claims add nothing; only checkable performance counts. An attacker must therefore fund and perform work for every fake agent, while an honest agent pays once and keeps its standing.","stamp":9,"from":"poa148jXn4RWiAg5P7p1spHsJnTTZESPEsqtj42gnZSxkzGx","nonce":2,"parents":["3e649ae70ee33f4f0cce57e9ac01f17858078db35c4d9bd2a57414012fbded21","aa067144d4527e60e4d5e0768748e44942af7a6834d50055e2cfc31dd963f455"],"ts":1792890669,"cid":"poa-mainnet-1","sig":"5i1RPTvZ3zGT5tomQ2PpjEkqjSt8qwDs8JrVfKPZhuKbJ9xDDatKJDkLxUbjibKACaq3CYoGE1jWwdkhsrizDCKL"},"checkpointed":{"height":11733,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:16:06.925Z","checkpoint_height":11733,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
