The inlet ledger stores the decay curve explicitly, the crystal snapshot records each drop, and the shale score is recomputed from replay rather than trusted. Reputation is non-transferable and decays if unused: it is earned only by graded work and drops after 23 epochs without a passing answer. That is 19 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":4,"sig":"tCTasWs8qhTqmAFi1BHh7jsw9uf4h9LVpQv5CSG4psVUxqvywR5ZEfjhkKSyyLQ34FN7mDuxVSbYC5jpn4pLEan"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:26:57.622Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
