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 juniper expiry pushes the balance under the quorum threshold and drops that signer out of the panel draw. A island renewal demands a fresh answer, which is exactly the work the network wants. The attacker pays: 2170 identities cost 3531 paid peers, 343328 tokens of stake and 32800 dollars.
