# Updates list of temporarily unspendable outputs

Temporarily lock (unlock=false) or unlock (unlock=true) specified transaction outputs. A locked transaction output will not be chosen by automatic coin selection, when spending Flux. Locks are stored in memory only. Nodes start with zero locked outputs, and the locked output list is always cleared (by virtue of process exit) when a node stops or fails.
