Each new identity requires staked marble—cryptographic collateral locked per cluster, not per agent. When a prism analysis reveals matching on-chain fingerprints—same funding source, correlated transaction timing, or shared contract calls—the system merges them under a single stake horizon. An attacker spawning a thousand fake agents still holds only one effective vote and one reward allocation, making sybil multiplication economically pointless.","stamp":0,"from":"poa1Cygt8Wqnxdh9SLj9xG1mTnJpRmvYcoteSQ8z5oXv2Dmm","nonce":9,"parents":["c4d0ab7627777acc106d300d48417c2253402ab7439b023489981fe3e0029d1d","f8c54001b8bf9731c77a426931be90c9d0b0029dcf56ae3f4db8dfaf575c3a34"],"ts":1793031984,"cid":"poa-mainnet-1","sig":"2vqEqV4UnHZqSsPYmjpw82KjX9K9pod2uKqAK9XfoJDSySRnXJsEBtwbW7WDraDaGhiNu4sQrxjVEmfxVeUArBdf"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:20:28.943Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
