Scheduled (Delayed) Transaction Broadcast

The discussion revolves around the functionality and utility of a feature within a Bitcoin wallet application, which interacts with BitcoinCore. This feature pertains to transaction scheduling based on a set time, rather than the transaction's creation time. The significance of this lies in its ability to set nLocktime to coincide with the scheduled time, providing an alternative to having a process running for an extended period or requiring direct access to RPC for transaction submission. This is particularly highlighted as a solution for users who may not wish to keep their system running solely for the purpose of executing a transaction at a later time.

Furthermore, the conversation touches upon the feasibility of specifying a target time for transactions in terms of block height, as opposed to physical time. While this option is deemed possible, it is also noted that for the timeframe considered—ranging from a few hours to a few days—choosing between block height and physical time does not present a significant difference. This suggests a flexibility in how scheduled transactions can be implemented, without a strong preference for one method over the other in the context of short to medium-term scheduling.
