Difficulty in verifying bitcoin-core signing keys How can I verify bitcoin0.19 signature bwith gpg?
I read I should use gpg --recv-keys signingkey, but I don't understand where is the file signiggkey. I tried to download Bitcoin Core Release Signing Keys v0.11.0+ but what I got is a .asc file, which I don't know how to use
With the .asc file, you can do

gpg --import &lt;asc filename&gt;
