Matrix is probably something worth looking at, at least from an intellectual standpoint, for you.
It uses shared message state and a DAG, plus some fancy perfect forward secrecy (using Signal’s Double Ratchet algorithm), which is at least interesting.
There’s also Tox (chat/protocol) if you want totally distributed chat.
Personally, I really like distributed models from a theoretical standpoint; but for end-user applications they pose very difficult constraints, we live in a world with ⪅50% publicly routed IP for one, they fundamentally require immense data replication, latency in peer-finding, bandwidth constraints, and ultimately sub-par UX. I thought IPFS with a way to pay nodes to pin content was a really neat idea, but hasn’t caught on, for example. Not to discourage you, if you think it’s workable then have at it, but I think it at least explains the current state of things.
