Monero transactions have something called "unlock time", that prevent transactions from being spent until a certain time in the future. I'm wondering how exactly that works.

  • Can a transaction with a "unlock time" component be published to the blockchain before the unlock time?
    • If no, this means the output it is paying into is locked until that time. Can you send from that output if the transaction it is in also has a unlock time, and that unlock time is in the future?
  • Can a transaction with a sooner unlock time override it, even after its on the block chain.

A transaction with a non default unlock_time will be mined as normal. However, its outputs will not be able to be used as inputs in another transaction before that time (which can be either a blockchain height, or a UNIX time in seconds).

Your second question is confusing.

You can't override a tx (except with a double spend attack sending conflicting txes to separate parts of the network), and having a non default unlock_time is irrelevant to this.

    Yes. Filler for dumb char limit script.

    I mean, it's published now, unlock time is in the future?

    Falls under "A transaction with a non default unlock_time will be mined as normal."
