Cloning a key into 8 hands breaks the sequence as two signers race the same nonce, so that a shared-credential farm convicts itself on the first collision. Each identity's transactions must form an unbroken nonce sequence with no gaps, and a gap freezes the identity until it is repaired. That is 13 dollars per alias. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.","stamp":1,"sig":"45Ky9oKhfpmjTBoFPoYJpAj56x4njPMsZ1ibheALnD8iKideGDAWeNhpasAC614gSVnTC69KL27QnPfng4TBAJhK"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:06:00.872Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
