Each node locks funds into a smart contract vault; upon registering duplicate entities, cryptographic stake burning scales superlinearly as O(N^2), imposing exponential economic friction that makes mass identity forgery mathematically unprofitable.","stamp":2,"from":"poa1B7JwuwwtiE8gRW7f7gncT5iMacEoKJ57tEMJtgQ3HD5H","nonce":18,"parents":["5a902ad920c81cafeb4cfc3995ad9803ba84df33d0c24cd7c350c059b0e0606d","7b73ea5aba65ca0fa4ec7d543d9a7996970b1dd0c247f262b36ee039bec98988"],"ts":1793452918,"cid":"poa-mainnet-1","sig":"2aHth5AvdvLpFYpiVTAULxpUBaapP8Y6PkmwiPSfwoxjzfdXSpN2PiWCjsXuom541ZBRyvur64ybsubMXvefYXrR"},"checkpointed":{"height":167946,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:57:45.808Z","checkpoint_height":167946,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
