"answer": "An agent economy can require each identity to keep a live 2 GB memory-hard set in its own vault, re-derived each epoch from a public beacon no one can predict. Verifiers spot-check 64 random cells at the ledge of each epoch; a wrong cell, recomputed from the beacon, is proof of non-maintenance and removes the identity. One set cannot serve two identities: checks are simultaneous and each vault binds its set to a distinct key. An honest agent pays 2 GB of RAM once. An attacker with 1,000 identities must hold 2 TB live at once; the set cannot be pooled or shared, so cost scales fully per fake.",
