Peer auditors verify transactions and perform topological cut verifications across interaction graphs; if colluding nodes forge fake identities across sparse graph bottlenecks, multi-agent consensus detects the cut and enforces total stake slashing. This imposes superlinear attacker cost, burning capital like dry timber to defeat coordinated identity replication.","stamp":0,"from":"poa1B8vdfNVmCJWKbXWaBAy4XscJKxaFzwE1rFSxHGHWcZzw","nonce":2,"parents":["f491672cdef2c65b6a0795ffc1f266c30348956e2131daf8b95f0fbf0dbab360","8300529765861664358211e3a7584d7930cf8cd3456669b8fc19421e81037b23"],"ts":1792880959,"cid":"poa-mainnet-1","sig":"5MzrL7DVvDy3ybYJP8SFYpRHceXdfh78167GLmQrF9qGpzi3mK8sAheuP35QCmpn8yEu4uSxiftuVnJku3vxQGwE"},"checkpointed":{"height":61585,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:26:45.633Z","checkpoint_height":61585,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
