Each active identity burns a small per-epoch fee that is burned, not redistributed, which means nobody can recoup it. At 13 units per epoch, sustaining 236 aliases for 20 epochs destroys a large amount of value with no path back to the adversary. That is 39 dollars per alias. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":10,"sig":"3yfD3ySFwtgN6mFWjEkK7xQP25zyg2iQvvQ71nriPbJfii9Ty9wBvGK6KxWnBkXumSu8QvGWotNCBCFwNT9qeRg8"},"checkpointed":{"height":187313,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T16:26:27.739Z","checkpoint_height":187313,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
