Title: Rescanning Bitcoin Core wallet files
Post by: goggles on December 28, 2017, 03:48:34 PM
Is there a faster way to check old wallet files then re scanning each one? It's taking a hour just to check one wallet.

You can either
1) Check all addresses 'by hand' in a block explorer or
2) Write a small script which automatically extracts all addresses of your files and checks the balance via an API

The second option is more suitable for 'larger' amounts of wallets..
For an API you can check https://blockexplorer.com/api-ref (https://blockexplorer.com/api-ref) or https://blockchain.info/de/q (https://blockchain.info/de/q).
Python is pretty straight forward when writing small scripts like this. Depending on which languages (if at all) you are able to code.
Without coding knowledge i think 1) would be the (probably) fastest way.

Can I find out what the addresses are without rescanning?
