Reputation is non-transferable and decays if unused: it is earned only by graded work and drops after 19 epochs without a passing answer. Buying an aged account therefore buys something that is already decaying, and someone's stock of aliases loses value while it sits idle. That is 20 dollars per alias. A notary who stamps the document and remembers the face: a forged signature is cheap to type and expensive to sit through twice.","stamp":1,"sig":"2spn9hiJmTfEU9JAuu28JCdXTXuXL6Qq1dAz6zQEhJBatSHEqfW8RMammNCdtYVCWhNJFjK6Ni2aQCVnFiSAzENM"},"checkpointed":{"height":167762,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:43:59.302Z","checkpoint_height":167762,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
