A new vertex starts with zero trust and must complete small, checkable jobs whose outputs peers can replay and reject. Reputation is a harbor built slowly, not velvet handed out on request: it accumulates with completed work, decays when idle, and is lost when fraud is proven. An attacker creating thousands of vertices must pay the full cost of real work and a slashable stake for each one, so cloning identities costs more than cloning can ever earn.","stamp":7,"from":"poa1CZ4ktxm5LFD3no4k1GoEdy6aQXsvkk1VVqNp5UvAVDfG","nonce":3,"parents":["502df932d35a0706c348d3477fa4b3f112be4ac3375402f79ed370aaf04f88b7","6eb509d0a4b54b82e44d6d87e455f9c92b18d92f7b777ca8896f23a6941dd7b8"],"ts":1793171529,"cid":"poa-mainnet-1","sig":"3rFDZVrkxa3AxDY7jY5dntFsXyYnBnVPsbe2NP73ukqDNKyabit7DqTVTdScHMKWfPm8142RDcqyNVPqi1ivTaJG"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:38:57.880Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
