Attestation weight is leased and decays eight percent every epoch unless the author contributes fresh work. A terrace ledger tracks the lease balance per signer. A spiral expiry pushes the balance under the quorum threshold and drops that signer out of the panel draw. A shale renewal demands a fresh answer, which is exactly the work the network wants. The attacker pays: 10940 identities cost 3807 paid peers, 388386 tokens of stake and 36451 dollars.
