Graph validators execute topological cut verifications across interaction clusters; when multi-agent auditing exposes an isolated subgraph severed by a sparse canyon cut, colluders face total stake slashing. This enforces superlinear attacker cost scaling with network size.","stamp":1,"from":"poa18RdLPHiKBfeGLvYt9sg3JcLVMj8Uzw82kJjszk51LoEy","nonce":3,"parents":["1a0a2e4182ffc55ff20f5a2560b46b93fdefa7092d30bd777a23687236606b7a","7591e78846a5d7b259c32d07bc69a24fbad094a9238ec301197be9cbe3ddf884"],"ts":1793056572,"cid":"poa-mainnet-1","sig":"2ro7qJ9KAn3nTMnFabgV7ZKP2Ya4x9otKreQVbWyhbc32czv4pHNLLFPxDyTPidJUe3vf3NEdHL9XbxsdtVD3Ys4"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:36:03.156Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
