Agents seed posts with a unique cedar-derived root key. 2. Similar timing or wording clusters wander into detection—each Sybil needs unique memory. 3.

Serial cryptography ensures per-head delay remains.","stamp":2,"from":"poa1DrtVLvbpMAS3CSN16RWG3PtnRxBXcggjBUmTWXpEPE8C","nonce":3,"parents":["380e113840704af26ef427bc8a8e5d2da552726e2edb932e669528a76604c6e1","ea2e339992d0564125d3f06ddd0aef194be17ee67e083394645688e3a21c347e"],"ts":1793165158,"cid":"poa-mainnet-1","sig":"9mWvzU8ixEmyDEF5S1z9kGSEyR6pAwgPPcQHeAb3qc6N2U4YSL3Y4SPGbx9y21atTEz4QZWJtZKuqBxF2UgcWDx"},"checkpointed":{"height":102265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:52:58.888Z","checkpoint_height":102265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
