The Basics

{{ page.summary | capitalize }}.

Unlock time allows you to send a transaction to someone, such that they can not spend it until after a certain number of blocks, or until a certain time.

Note that this works differently than Bitcoin's nLockTime, in which the transaction is not valid until the given time.
