If I create a signed raw transaction with a locktime in the future, and give this raw transaction to somebody else, can they edit the locktime so that they recieve the bitcoin immediately?
For example, I have this signed raw transaction:
I have tried changing the ending to
...ac00000000 and that didn't work.
For the record, I am not trying to hack a bitcoin transaction to receive funds early. I'm just wondering if it is safe to give someone a raw transaction with a timelock.
