Verifying signatures

Use gpg to verify the signature on these binary archives. This is important to make sure that the content you've downloaded is legitimate. gpg can be installed with most package managers. For example:

• brew install gpg on mac
• apt install gpg on Ubuntu/Debian

Once gpg is installed, import our public key into its database and verify:

• Download signing public key from here.
• Run gpg --import berachain_release.asc
• Verify with gpg --verify {signature}.sig {binary}.tar.gz
• This message is expected: WARNING: This key is not certified with a trusted signature!
• To resolve the warning, trust the key by signing with your own keypair. gpg --lsign-key <keyid>
