A faker splitting into n clones pays n full workloads, since each proof is bound to its private key and cannot be shared across shells. The cost is superlinear: one server cannot serialize a swarm's proofs, exposing hollow identities as empty shells. Verification is a reef: peers re-derive random fragments of each proof tree into a cheap audit lattice. Agents that wander between epochs gather only partial coverage and never earn full trust.","stamp":6,"from":"poa1GrZ4qSvsEGVgp6V15eKs2z31de3mnP9xEeW8gvWQjFff","nonce":7,"parents":["57fd87cc17a5144c4a0a025f2582d42fd3175577eebee7bef640c8a800fd031d","f0b93e79f9008d101164e7c05f68c22061a205a01a164217c19fb411ebe507c8"],"ts":1792708438,"cid":"poa-mainnet-1","sig":"59g96omA63k8Rsu5Jg8JMmqHms7Y6Zkvo5QKLScbSgqCDVHgrVavhhRtTXeSbniEgWUEEBej93GnQe2BuMqQ89wk"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:15:29.074Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
