Ratimov's Russian translation,
FontSeli asked how this can be useful for a normal person (thanks Google Translate). I'll answer this here.
I can think of several other uses:
- Say you have a list of your old Bitcoin addresses and want to know if they hold any balance. But you don't want to let any block explorer or Electrum server know which address you're looking at. By downloading all addresses, you can easily do a local search without anyone else knowing which address you're looking for.
- I've also seen cases where someone has an incomplete Bitcoin address, and wants to know if it's worth to pursue recovering the private key. Block explorers don't let you search for incomplete addresses. As a rediculous example, thoese are all funded addresses that contain "Loyce":
