Protocol

The Tron protocol adheres to Google Protocol Buffers. Protocol Buffers serialize structured data for communication protocols, data storage, and more in a language-neutral, platform-neutral manner using structured data.

(1) Protocol Buffers

Protocol Buffers provide a flexible, efficient, and automated mechanism for serializing structured data. They are similar to JSON or XML but are much smaller, faster, and simpler. Using Protobuf (.proto) definitions, one can generate code for languages like C++, Java, C#, Python, Ruby, Golang, and Object-C using official code generators. Additionally, there are many third-party implementations available for various other languages.

Protobuf integrates API definitions and optimizes data transmission to facilitate client development. Clients can integrate by fetching API.proto from Tron's protocol repository and using the automatically generated code libraries. Protobuf generates data access classes that are 3 to 10 times smaller and 20 to 100 times faster than XML. It creates unambiguous and programmer-friendly data access classes.

(2) HTTP

The Tron protocol provides a RESTful HTTP API instead of Protobuf API. While using the same interface, HTTP API can be easily utilized in JavaScript clients. The Tron network offers over 60 HTTP API gateways to interact with the network through Solidity nodes extensively.

Moreover, TronWeb is a comprehensive JavaScript library that enables developers to deploy smart contracts, alter blockchain states, retrieve information about the blockchain and contracts, and trade on DEX, among other API functionalities. These API gateways can be directed towards a local private network, the Shasta testnet, or the Tron mainnet.

Tron has both a mainnet and a Shasta testnet. Developers can deploy nodes, interact through TronStudio, or connect to the network using API through TronGrid services. TronGrid services consist of load-balanced node clusters hosted on AWS servers worldwide. As DApp development expands and API call volumes increase, TronGrid successfully handles the increased API traffic.
