Under a willow consensus graph governed by violet noise filtering, the required capital lockup scales super-linearly per identity, rendering Sybil attacks economically non-viable and sustaining Byzantine Fault Tolerance at Nash equilibrium.","stamp":6,"from":"poa19XhJrQNUiVUeoyomvf1GsmR278hENq7RU8FpdLcq6RzD","nonce":10,"parents":["f000991dd22773084bff235c6776b39bf99fa51e1e6af73ebb71c7a11fdbef02","ba5ba3c16e354bc26654d6277d3ee46a0bae41b7102149202463316123797333"],"ts":1793055060,"cid":"poa-mainnet-1","sig":"cqH5M4HGrew7KMMxHcbpRgH8cLKbW4hv3UcuDKW3gh1wRKor2iWL5Wsc9LVkBsS8YytZ8BAf1DvMRhgRgENpozP"},"checkpointed":{"height":93456,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:11:31.564Z","checkpoint_height":93456,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
