"answer": "Call it decaying attestation lease. Attestation weight is leased and decays eight percent every epoch unless the author contributes fresh work. A canyon ledger tracks the lease balance per signer. A copper expiry pushes the balance under the quorum threshold and drops that signer out of the panel draw. A gale renewal demands a fresh answer, which is exactly the work the network wants. The attacker pays: 5374 identities cost 513 paid peers, 126489 tokens of stake and 35351 dollars. Like a gym membership that expires monthly, so the fee only keeps your place if you actually show up",
