I usually only install on like a Raspberry Pi or VM for these toy distros

Are any distros using block chain for this ?

I am used to using code signing with HSMs

I’d install it as a VM maybe,

I don’t think so, but it’s always struck me as a good idea - it’s actual decentralised verification of a value that can be confirmed by multiple people independently without trusting anyone other than the signing key is secure.

Me too, but that requires distributing the public key securely which… is exactly where we started this!
