The story is confusing some people.

Claude found a file on the computer that the wallet owner had not found. Claude didn't crack a password or do anything magic, it just searched for a file that the wallet owner had not thought to search for before.

So, where the wallet owner had previously only tried to access /Users/example/wallet.dat, Claude thought, "why don't I check if there is another wallet.dat file elsewhere on the system?" which it did.

The outcome is the same, it is great that Claude tried something that the wallet owner hadn't tried, but this is more an example of how dumb humans can be rather than how smart Claude is.

The trillions of passwords are a red herring and unrelated to the solve.
