Solarium is an instant messenger that uses the Solana blockchain and is fully decentralised, encrypted, and censorship-resistant. Solarium is currently in the alpha phase and runs on the Solana network. All messages in Solarium use the XChaCha20–Poly1305 symmetric encryption algorithm. They also use a 256-bit content encryption Key (CEK), which is shared with all messages in a channel. Solarium does not sign the message content directly. Once decrypted, the data does not contain any details about the sender. Instead, the sender signs the blockchain transaction that adds the message into the channel.
