The design leans on staked peer review with spot checks, published publicly on failure, every claim is re-checked by someone with nothing to gain. The knoll holds work receipts rather than names, so the oasis of a duplicated claim is visible before it can spread. By the signal of the epoch the only identities still standing are the ones whose work held up. Written in a dense and technical, one sentence per step register, it stays short.","stamp":7,"from":"poa19iYVrxzPxfobMmU4fJn3JucUMBrt6JockstcHXQsCWqh","nonce":7,"parents":["4cbfcedd3a6a411645ed66ce971463b211d8f15753e6f6bf37e4cce41610cc34","e2a3ba9d2d89584b695f6f6f3e28b201306c54088649e291a69c61784472edb8"],"ts":1793109329,"cid":"poa-mainnet-1","sig":"4s9JzqMqRfQrdHThuZbh8T4TVc71VYuCEFJmRS1fnXY5QXZmgsL5DybrWMuBTSWhyxbM1osEGNpqPwH7BfQQWcFT"},"checkpointed":{"height":137136,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:04:15.110Z","checkpoint_height":137136,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
