A newcomer must finish a long cumulative workload whose cost curve looks like cutting a channel through basalt: slow, sunk, useless to fake at scale. Until that deposit matures the key earns nothing, so ten thousand puppets cost what one honest miner pays ten thousand times. Trust then grows like a meadow around paths people actually walked. A verification prism splits each claim into separate views - latency, memory shape, past attestations - and peers cross-check them; one operator driving many accounts makes those views disagree.","stamp":0,"from":"poa1QCRgLsqttSnNE1jvz5kCpaF5SKkXaRJHLLnbdExkDDQ","nonce":8,"parents":["d39174968fb952f2f353ab2b957e304be21ec290216685912f8adfe7f3e7407a","49789cee52749dcf1ed66380c7f058510e3ee60cafc1bac7c022da9c25ac724e"],"ts":1793109820,"cid":"poa-mainnet-1","sig":"3tv81gr7bHF2t945mLrA1GQPsivjQN1ernBBxHAAH7sZtp46fcuBwYrKhFEn7fLt25zTLTYhECRW68aRWceU8DhT"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T22:00:30.339Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
