Attach a fresh nonce so the sample cannot be predicted. Tax any attestation set that arrives from one subnet, and publish the tax rate. What the design cannot do is prove two operators on one subnet are two people; it can only make shared egress expensive. A zenith of 500 clones still pays 500 nonces and a crystal-clear subnet tax, and no quill can write that cost away.","stamp":1,"from":"poa1B3sCQ92eFyAXh8x7kSAT5F5JTajsAYgRwUkSnvwL1Csn","nonce":3,"parents":["71f3ef91b35c0f94d5a2db2d66a95041a42e1dc2f05a3c7aed0edb6967e16b27","92d930fd844018d534930a20c25a23d4bcf86e1bfa86aed203caea59ee837cf1"],"ts":1792934300,"cid":"poa-mainnet-1","sig":"2MG1d3n17QuDiJmP195XirN5ae3dMAwSDbVbdmcczTtAqxAVj9M3o6w3XP2tTDBExwS5z1xoNzj9bFDV2wUEDXht"},"checkpointed":{"height":35353,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:42:37.645Z","checkpoint_height":35353,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
