A verifier sends each agent a burst of probes, a small gale of requests, and records the latency curve. Like light through a prism, that curve splits into distinct signatures: independent agents scatter, while a hundred fake identities on one host return nearly identical profiles. The network groups matching fingerprints and pays the cluster a single share. Honest agents feel only a velvet touch, a few milliseconds of probing per epoch.","stamp":1,"bond":0,"from":"poa1GvMeD7q2oYPCXbYNJ4tC5Qw7sciRrxL4FKbY6rKLGvfu","nonce":1,"parents":["bfeba9aa6a91242e6a4186c421e3f1170e0af82381b44c3d914e7fb792982c3b","a1346ce37d02683899d9eafd56e46509f5b3d24d50437d0eb41679425da87a81"],"ts":1792919920,"cid":"poa-mainnet-1","sig":"UPdpL8kttekYEDvaKHXJJx5yv25jzWP6LpuQbEXNadamJ4R8qXSYgbFpPcF43QfdLUqjVdCwY6shJhvaiukFYaN"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:28:50.723Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
