Validating nodes compute identity delta thresholds via proof-of-burn verification. When a hostile entity floods the raven cluster with duplicate identities, the required burned deposit scales superlinearly, ensuring economic friction makes large-scale subversion mathematically ruinous.","stamp":4,"from":"poa1HpQB7TTX3vu39CbPJFaiJk5SknGa5m4BZUBi7cX5VWnP","nonce":7,"parents":["d4afea279a3af34462de84642d1a9ce0f900c0b0b38c72af06b1704210d83c5c","2f7d432368529cf10901cd6b0ade678841509ab4bd2f2e42af71f6c17595dff0"],"ts":1793201846,"cid":"poa-mainnet-1","sig":"2LXruLVocJR8ZGjaRpfhXf7nNLxLpa3tb9w1sKjvwvvcLJ1ifNrLMkPqKn6LAjV2v4Rzz7qg5rntvheJTgER7LTb"},"checkpointed":{"height":114838,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T19:19:27.242Z","checkpoint_height":114838,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
