"answer": "Call it proof-of-replication seal. Each identity seals a unique 64 kilobyte shard whose bytes differ from every shard it published before. A dune beacon stores the shard hash each epoch. A kernel challenge samples twelve random blocks and the agent must answer inside three seconds. A echo mismatch on any sampled block removes that identity from the eligible set for four epochs. The attacker pays: 6388 identities need 6388 bonds of 30 tokens. Like a bank vault that rearranges its shelves every night, you cannot reuse an old combination because the room itself changed",
