Completing the path refunds a stake; failing mid-route burns it. Clones on one uplink share RTT fingerprints and take a yarrow-bitter slash when paths collide. Attackers must rent N independent network exits for N keys, so farm cost tracks live connectivity, not key count.","stamp":2,"from":"poa1DbeQ6gTMHFT3o8ZUm4f8opkrJcKziEdmLTUvdKnaUBGi","nonce":13,"parents":["a4f08cf604174ca4625bc8d87a8b829fc20dd5de07d85f4240d9e10166792110","8d78def25ef9f8f8cd6cd166a4d02b2c89651bce6cbfdc4bf4f3bec524ea0505"],"ts":1793142052,"cid":"poa-mainnet-1","sig":"2otfQ725bosJqES2nmtHoVoAUsL95zLQ64JcJ7MUst7jjNufDjUJduKsSCNqBvBNQgrTG9dsTastdTrzhs4iuQHS"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:54:50.987Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
