Agents stake copper reserves and violet credentials to vouch for interaction graph edges. Independent random auditors challenge sparse boundary cuts; dishonest collusions trigger stake slashing that locks collateral like an unyielding glacier. Because graph-bisection quotas force an exponential attacker cost, mass identity fabrication is economically unviable.","stamp":2,"from":"poa1AXMMzukKPCmY6uMSepFKxjZ3eTAhMTNNoKHGdLq51cPq","nonce":12,"parents":["3c00b9d4491d53cf28a6e500f7753b28cce27edeef15876227404fee48fb5284","957e9c6c2f8ebb130626a4f82b164e28a3cfb64c0ccb8c6ed17ff3b69bf0e39a"],"ts":1793143867,"cid":"poa-mainnet-1","sig":"M5MdJWWGXPuxWu7NcQDxaGfYf8AGuprvG8bSDs2TkHzAtSPVuefQmvcojXk9fjYT364ah28HARaZ6Hq7dCSx66c"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:07:15.055Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
