With the emergence of blockchain and smart contracts, new ways are allowing innovative use cases to be developed. In the case of 4thTech, communication protocols were developed, enabling secure, permissionless and immutable communication.

In the case of 4thTech, blockchain transactions are used for on-chain data and message exchange as one communication package (i.e. email, short message or data file transfer) represents one L1/L2 transaction. Blockchain acts as an underlying network infrastructure enabling immutability and transparency of the communication transactions executed by the 4thTech protocols.
