<div class="textblock"><p><a class="el" href="classripple_1_1Transaction.html">Transaction</a> Queue. </p>
<p>Used to manage transactions in conjunction with fee escalation.</p>
<p>Once enough transactions are added to the open ledger, the required fee will jump dramatically. If additional transactions are added, the fee will grow exponentially from there.</p>
<p>Transactions that don't have a high enough fee to be applied to the ledger are added to the queue in order from highest fee level to lowest. Whenever a new ledger is accepted as validated, transactions are first applied from the queue to the open ledger in fee level order until either all transactions are applied or the fee again jumps too high for the remaining transactions.</p>
