Through a low-latency whisper signaling protocol, peers validate state transitions across an ocean of distributed proofs. This mechanism forces an attacker to burn immense computational capital and time to forge the long-term history required for identity acceptance.","stamp":1,"from":"poa19FWw6rFvsqrC4PTZ8xvqSLJBJmpX2VTyLP1oMdLGTxsB","nonce":15,"parents":["0de723c6d51d28fe33f0ac9422a0f9a7bf5e05cf1e9d4de2b42549ec8bbd741b","b8ccb6ff6dabf4c94c5da27fe5223a94fbb0d3f950a7e6528b36b0169412bba7"],"ts":1793187077,"cid":"poa-mainnet-1","sig":"5CNSVWpaADHzfwif5s31fSkSoP5qQZCjdBjPPpn83WAum9KMxqRLNeUDvZuBVqDBNQchpcuZv8vV9BxqUpW9uqrk"},"checkpointed":{"height":125818,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T03:02:26.726Z","checkpoint_height":125818,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
