Yes, it is possible to scan multiple addresses simultaneously with your own node using the scantxoutset command in Bitcoin Core. Instead of querying each address independently, you can provide a list of addresses as an argument to the command.

Here's an example of how you can scan multiple addresses simultaneously using the scantxoutset command:



Replace addr1, addr2, and addr3 with the addresses you want to scan. You can add as many addresses as you need, separating each address with a comma.

By providing multiple addresses in a single command, you can save time and speed up the scanning process.
