Could you expand on what you mean by a variation of Signal? To me, Signal’s main feature is just that it’s a reliable E2E encrypted messaging app, implying two ends to communication. A blog post interface implies one-to-anyone communication, so I’m confused what part of Signal you want to emulate.
I am aiming for a decentralised-FB like experience on Signal. And I honestly think it is feasible.
On FB, you tag a post with intended recipients(default:All "Friends"), people log in and get fed these posts with FB fiddling along the way.
Signal with a redesigned UX could show a doom scroll of posts that friends send you. Not that I think this is great, but user adoption for familiarity.
Signal E2E delivers the message, the new UX displays the posts. You apply heuristics as you want, all without ads or data gathering by a MITM.
But... public posting is a thing. I am hoping that IPFS combined with cryptographic signing for authentication, could fill that role.
Hence my comment that IPFS could hopefully lead to democratization. Although, I am also concerned that IPFS will also lead to "undeletable" content, but that seems to be almost a thing anyway.
Scuttlebutt is the software you're looking for. Check out the patchwork client. Posts are public by default but you can make them encrypted so only your friends can read them.
There's also cabal chat which is based on the same underlying technology but is chat focused rather than Facebook like.
