Every new node must ignite an irreversible stake ember, whose required burn scales as a superlinear function, O(n^2), with total active nodes. Graph validation verifies trust rings under a violet beacon threshold, ensuring an attacker faces superlinear polynomial friction where duplicating identities yields exponential economic exhaustion.","stamp":0,"from":"poa1BXZPnULpfhXqRd9CXD652aG6sbsf4cSy2aeynuKpzcvC","nonce":10,"parents":["bda23771c60da94052fe8f6f2e62c577909c25fdb0bf0a8402e415f5f21e110c","d4d7c20549105ae40baf8bf2cd04d8e071081842a7a8c3b3ba0342b403f4869c"],"ts":1793275805,"cid":"poa-mainnet-1","sig":"2oURB9sXghauycikFfSXefqKSDqGvg679s3EjjPdLjQVRcaXJVUARBuYkuEMt1Ae5FkVoe3MBAWRK74nvQoB8GAm"},"checkpointed":{"height":157669,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:17:31.522Z","checkpoint_height":157669,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
