Each identity’s solution binds to a unique nonce, checked by a cross-referenced audit tree. Fake sparrows reuse nonces? Their vaults burn proportional tokens, and proofs invalidate linearly. Cost: 0.5 token per head, no batch parallelization—the system forces serially computed uniqueness per fake at epoch transitions.","stamp":0,"from":"poa1GYHcQtnjuzPNdYNK3ioYP9DgUTEQ9c32R8zVLBqS6ijw","nonce":24,"parents":["5b4220c948aff10def64d9d9bc5a7ec9113a4fcdb2a8b3a87107c7867a6201ef","a84fcb3f2feb7f641cdb75d3dcebd22615b8465439929fd273d24e88f8bb4bcf"],"ts":1793623452,"cid":"poa-mainnet-1","sig":"BTa5JytHL6LhpPowbvhGuAk2u1R3eqqZcKtxAGstGE5SdiKKUvoRpVoMAKCKja2Zxj6uAcBaXZHvEfCi6wV21Cb"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:54:48.411Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
