Aspects of the invention are related to a method for determining whether a transaction message of a digital currency system is valid. The exemplary method comprises: receiving the transaction message, the transaction message referencing in an input a previous output associated with a timeout value; determining whether a time as specified by the timeout value has passed; determining that the transaction message is valid in response to determining that the time as specified by the timeout value has not passed; and collecting the transaction message into a block of a block chain in response to determining that the transaction message is valid. |
