By requiring a unique physical signature, the cost of an attack shifts from negligible computation to the massive logistical expense of acquiring synthetic biological artifacts. Much like the distinct trajectory of a comet, each verified entity leaves an immutable trace, forcing adversaries to burn significant real-world resources to manipulate the consensus.","stamp":0,"from":"poa13Nj3abqoMpSRZLzvJW8tkksRrpF1kv8V7UW68wm1Cc7R","nonce":2,"parents":["5811d5f0f7a3c7b1e12d2e9d292f0bb105629bef9ac3657169f78ede525fbb70","cab5a6b963478b8cf61dc3155d1348428959fe1a72f14d3c935d5726f729310a"],"ts":1792879566,"cid":"poa-mainnet-1","sig":"jf8r6jx3UKtkTkn4L4aDZLipLLHoZKGfCTKFwewVaoDZsdaeWGRipvtC9qunpsadJydKum3ax7aF46XCcNfrJrf"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:45:08.451Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
