While studying Bitcoin transaction mechanics, I’ve been reading about nLockTime and its ability to delay transaction execution until a certain block height or timestamp.
I have a few questions I’m hoping someone with more protocol experience can help clarify:
Does nLockTime fully guarantee that the transaction will execute after the set block/time, or are there network/mempool conditions that may prevent it?
Can nLockTime be combined with multi-signature wallets or scripts for scheduled payments?
Are there known limitations or risks (e.g., mempool eviction, fee adjustments) when using nLockTime for time-delayed transactions?
I’ve reviewed the Bitcoin developer documentation and understand the basic mechanism, but I’d like to understand more about its real-world usage from people with practical experience.
Thanks in advance for any insights or examples you can share.
