Translations: Coin Shuffling/70/en
Once started, the Shuffler monitors the blockchain state for transactions relevant to the specified shuffle, and automatically submits the required transactions on behalf of the user, performing shuffle processing, verification, or cancellation as needed. To do this, the Shuffler is required to keep the users' secret phrase in memory, same as when forging. And just like with forging, restart or a crash of the node requires restarting the shuffler manually. The shuffler remains running for 720 blocks after a shuffling either completes successfully or cancelled to make sure it is still active in case of an (unlikely) blockchain reorder.
