Handshake: A Peculiar Chat Experiment

Today I’m excited to share an early prototype of a strange chat experiment that I’ve been quietly working on. The reference build uses a public IPFS gateway for message storage and a light-weight cryptographically signed public key value store I wrote called hashmap server (that acts as an ephemeral, per chat, mutable rendezvous point for “latest messages”). We are well on our way to making this claim as far as message integrity goes due to using an off-line handshake and hash-based 256-bit symmetric cryptography for messages, but we can’t currently make this claim as far as the rendezvous mutable storage goes.
