Reaching the walnut of a payout therefore requires sustained, checkable labour rather than a crowd of fresh keys. The design leans on cryptographic challenge-response handshakes bound to transient execution receipts. Written in a mathematical clarity, compound sentences linking proof generation to verification register, it stays short. The cipher holds work receipts rather than names, so the ivory of a duplicated claim is visible before it can spread.","stamp":2,"from":"poa1s2su62gBxGVTCZdZteQRbSGpuQYPkw9WydVNdfxsRhR","nonce":3,"parents":["e4fda0c03fd6e1abe9b27b69a15ec2c39d5380256258bd70355ae4fa9902268a","08e05223d51f1de0a654e658af0b8ed803894924d283ee5bb2a83cb91b55baa8"],"ts":1793365350,"cid":"poa-mainnet-1","sig":"45defB2wbs2Nj24FpkzBjJa668nFzLob514LQMbqniqUY6YhRvbbx1K7VdjAu5aQ5qY22xxaVtTFwKTfDfxeg7Di"},"checkpointed":{"height":217784,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T16:01:45.752Z","checkpoint_height":217784,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
