About

Cwtch (/kʊtʃ/ - a Welsh word roughly translating to “a hug that creates a safe place”) is a decentralized, privacy-preserving, multi-party messaging protocol that can be used to build metadata resistant applications. Decentralized and Open Participants in Cwtch can host their own safe spaces, or lend their infrastructure to others seeking a safe space. There is no “Cwtch service” or “Cwtch network”. The Cwtch protocol is open, and anyone is free to build bots, services and user interfaces and integrate and interact with Cwtch. All communication in Cwtch is end-to-end encrypted and takes place over Tor v3 onion services. Cwtch has been designed such that no information is exchanged or available to anyone without their explicit consent, including on-the-wire messages and protocol metadata.

About

Solarium is a fully decentralised, end-to-end encrypted, censorship-resistant instant messenger based on the Solana blockchain. Solarium is currently in alpha phase, running on the Solana devnet. All messages in Solarium are end-to-end encrypted using the XChaCha20-Poly1305 symmetric encryption algorithm, using a 256-bit content encryption key (CEK) that is shared for all messages in a given channel. The message content in Solarium is not directly signed, i.e. the data itself, once decrypted, does not contain details about the sender. Instead, the blockchain transaction that adds the message to the channel is signed by the sender.
