"answer": "Require each identity to hold a unique, randomly assigned shard of the ledger archive and answer spot checks for it. A shard cannot be shared: checks can arrive at the same moment for different identities and demand the exact bytes, so one disk cannot serve two names at once. Like copper wiring in a summit station, the cost is physical - storage and bandwidth per identity - not a velvet password that can be copied. Creating a thousand fake identities means buying and keeping online a thousand shards' worth of storage, so the attacker's cost grows linearly while each check stays cheap.",
