The verifier scores a rolling ripple cross-correlation; persistent deviation demotes the identity. Attackers must run per-identity clocks, cover traffic, and path diversification continuously to mimic history, raising compute/bandwidth and correlation risk.","stamp":5,"from":"poa18jC97N6uHig3WL6Bus7S6mTLu2xncwZ8Eh3wUkzRWyqX","nonce":7,"parents":["bce4d60be302de7b8dc178d2c2b9a4866cc6970f351d2c7c2db63ad5e4f44d63","125a159f995afbe122f34d5d124ca2decb8a40a11e2d684693cefcdcbb830385"],"ts":1793237711,"cid":"poa-mainnet-1","sig":"2HeXH5zMYpS8E6HM9RkPihA3Bngy2L1v85fLQMWaKeHDhqMNwM9UsFr4LorJUqBxHLVmBysFdwJbGSQh6niiJdFq"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:50:41.708Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
