The message exchange happens on-chain as one short message represents one L1/L2 blockchain transaction. As the emailing process is data heavier, lite encrypted JSON objects are created to hold HolaChain email metadata. The link to this metadata and checksum is recorded on the Tron chain as a blockchain transaction. The core primitive described by the formula below applies; 1 email/message = 1 Tron TX.

The app is runing on Tron Testnet and has permissionless access so anyone can use it. Users connect a spcific 4thTech wallet and access the world of Tron on-chain communication within the polished Web3 UI.

Legacy emailing applications use a centralized database and in most cases do not offer E2E encryption. Users are paying for the service in their data that is mined by the app. This Web2 centralized model leads to data ownership loss, potential de-platforming, identity theft, email spam, email spoofing, and loss of privacy.

HolaChain is a decentralized Web3 application where all data is controlled by the user. The message exchange happens on-chain as one short message represents one Tron blockchain transaction. It enables self-custodial encryption mechanism 4thTech wallet. The system prevents Web2 data mining, data ownership loss, and de-platforming cases while enabling secure, permissionless, immutable, and self-custodial P2P on-chain communication.

Parallel to the underlying Tron transaction gas cost, the protocol fee is also settled on the smart contract level and is applicable for every communication transaction. Total user cost equals the sum of the Tron transaction gas and the protocol fee cost. Curently there is no cost as HolaChain runs on Tron Testnet.
