## What it is
java-tron is the official Java implementation of the TRON Protocol, a DPoS blockchain with an EVM-compatible virtual machine (TVM). It runs as a full node that syncs the TRON network, validates blocks, and serves gRPC/HTTP APIs.

## Use cases
- run a TRON full node
- query TRON blockchain data via API
- deploy and execute TRON smart contracts
- operate a super representative witness node
- build blockchain explorers or wallets on TRON data

## When to choose
- you need to run or operate TRON network infrastructure
- you want to build services on top of TRON with direct node access
- you need an EVM-compatible chain node in Java

## When to avoid
- you only need to send transactions and can use a public API service
- you want to build on Ethereum or another chain
- you need Windows support, which is not offered

## Facets
- artifact type: application
- maturity: active
- function: blockchain, cryptography, networking, rpc, http-server
- domain: blockchain, microservices, developer-tools
- platform: jvm
- tags: tron, dpos, smart-contracts, tvm, evm-compatible, full-node, cryptocurrency-node, cryptocurrency, linux, macos
