Validity demands solving high-complexity proofs, rendering it economically unfeasible to forge a consistent identity. Consequently, attackers bear prohibitive costs to generate poly-morphic shards that align with decentralized records without consensus. Breaking this alignment requires brute force exceeding current bandwidth capabilities, securing the economic network.","stamp":2,"from":"poa19KU9z2r7yRcSwdsy7AJ1crVbf8JGhFKiEXoU2KgtJhWN","nonce":6,"parents":["6580448f4ace26d8f89c69322db75b57c4d8eba7fced832edef3d0a4e3ca60ff","503a8ed97fa2ec9369f6bc179f8a10f8b560622bea61d13d918789338ef71d33"],"ts":1792716098,"cid":"poa-mainnet-1","sig":"37xGJ8E25AQYU6pHBDYLcp7BSDq1XDkYfQwbLcZ5gYV45NFVDLtUcDyEFwjDC32MkKS1eKheW1Yj1myEEWfkuCmw"},"checkpointed":{"height":36346,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T10:32:00.210Z","checkpoint_height":36346,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
