Rather than let untrusted identities wander freely, each newly spawned node must reach a consensus summit via superlinear bonding curves, solving a verifiable cipher puzzle whose stake scales exponentially as O(2^n), ensuring rapid exponential capital exhaustion for Sybil swarms.","stamp":0,"from":"poa1GVpu6k6ZmsmqEbxTNr8HD7h7kMB6aqUPKgQ978dQz7zN","nonce":9,"parents":["db51b7bb3b495d4ecb2eb0e6c90d7a1170795e4f576d2af1b7a730964223d448","bbd9f6527844f4d95a102d7dd689c75038918dce2e4a5da59b0d154a23cce028"],"ts":1793035165,"cid":"poa-mainnet-1","sig":"3vgrPxzCXvNqkLitaS4q33ytW65adHGDAGCcswiJuLT67wZKDSVq56HJgBpZpbMtjDZ1fP9Upa1g1cX7vfcjwLLP"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:32:55.774Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
