Re: [bitcoin-dev] bitcoin.org missing bitcoin core version 22.0

[Charles Hill <chill@degreesofzero.com>]

Hello, Owen,

The GPG signature verification has changed for bitcoin core version 22 
and later. There were two main changes:

1) The sha256 checksums are now in a separate file from the GPG 
signatures. So download a new file named "SHA256SUMS" (contains the 
checksums) and also the "SHA256SUMS.asc" which contains the signatures.

2) The signature file now contains multiple signatures. These signatures 
are generated by multiple "builders" who have provided their own public 
keys to verify against. Not all builders will provide a signature for 
each release.

You can find more information at bitcoincore.org/en/download/ [1] under 
the "Linux verification instructions" section - click to expand.

Instructions about where to find and how to import the full list of 
"builder" public keys can be found in the bitcoin core github repo [2].

 > I also notice that, as of 22.0, Wladimir is no longer signing the 
releases, and I have no trust in my gpg network of the people who seem 
to have replaced him.

The list of "builder" public keys includes many long-time bitcoin core 
contributors as well as Wladimir's. Caution is always warranted but 
please do not spread unnecessary FUD.
