Privacy in online communication is a fundamental right of every person. Exchanging private E2EE instant messages securely over the internet without data mining, ads or tracking should be easy and accessible to all. Blockchain technology proposes the ideal foundation to enable this solution. Up to now, on-chain instant messaging deployment would be hard to achieve due to slow blockchain network speed, congestion and transaction cost. With the arrival of the Solana blockchain on-chain, instant messaging is becoming a reality. To address this issue the 4thTech developed a Solana-based dChat, which leverages blockchain trust to provide end-to-end encrypted immutable on-chain messaging.
