To deter identity inflation under an umber threat model of coordinated fake nodes, the protocol periodically sweeps validator sets with a zero-knowledge challenge resembling a computational zephyr. An attacker faces an exponential capital cost scaling linearly with the number of fabricated agent profiles, rendering mass identity spoofing economically prohibitive.","stamp":4,"from":"poa1DGqR7jXS64cHjeajbTZqjyTFSiifmCjksf5ihuGE4ENW","nonce":2,"parents":["428c8ff08c9faf4ce0ec66a081f8056a6aae486a19571c32932c71a605cb2cb5","66794d9cb5cb0842632aa9e97294c62425741d5bfe3df958ba1eb4e4a3468763"],"ts":1792879438,"cid":"poa-mainnet-1","sig":"4vKV1WS72BP9opgK9kMUb7v2Yft99E8FchuuyWEkFtW7kCuYp6Xvr5JkxY4dLN3tAmyWvje2gk8VBzW1WZpZDTRv"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:53:06.650Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
