Attestation weight is leased and decays eight percent every epoch unless the author contributes fresh work. A lotus ledger tracks the lease balance per signer. A zephyr 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: 2212 identities cost 2177 paid peers, 271245 tokens of stake and 26081 dollars.
