## What's TRON? TRON is a project dedicated to building the infrastructure for a truly decentralized Internet. The Tron Protocol, one of the largest blockchain based operating systems in the world, offers scalable, high-availability and high-throughput support that underlies all the decentralized applications in the TRON ecosystem. TRON enables large-scale development and engagement. With over 2000 TPS, high concurrency, low latency and massive data transmission, TRON is ideal for building decentralized entertainment applications. Free features and incentive systems allow developers to create premium app experiences for users. TRON Protocol and the TVM allow anyone to develop DAPPs for themselves or their communities, with smart contracts making decentralized crowdfunding and token issuance easier than ever. # How to Build ## Getting the code * Use Git from the Terminal, see the [Setting up Git](https://help.github.com/articles/set-up-git/) and [Fork a Repo](https://help.github.com/articles/fork-a-repo/) articles. In the shell command, type: ```bash git clone https://github.com/tronprotocol/java-tron.git ``` * For Mac, you can also install **[GitHub for Mac](https://mac.github.com/)** then **[fork and clone our repository](https://guides.github.com/activities/forking/)**. * If you'd rather not use Git, [Download the ZIP](https://github.com/tronprotocol/java-tron/archive/develop.zip) ## Prepare dependencies * JDK 1.8 (JDK 1.9+ are not supported yet) * On Linux Ubuntu system (e.g. Ubuntu 16.04.4 LTS), ensure that the machine has [__Oracle JDK 8__](https://www.digitalocean.com/community/tutorials/how-to-install-java-with-apt-get-on-ubuntu-16-04), instead of having __Open JDK 8__ in the system. If you are building the source code by using __Open JDK 8__, you will get [__Build Failed__](https://github.com/tronprotocol/java-tron/issues/337) result. ## Building from source code * Build in the Terminal ```bash cd java-tron ./gradlew build ``` * Build an executable JAE ```bash ./gradlew clean shadowJar ``` * Build in [IntelliJ IDEA](https://www.jetbrains.com/idea/) (community version is enough): 1. Start IntelliJ. Select `File` -> `Open`, then locate to the java-tron folder which you have git cloned to your local drive. Then click `Open` button on the right bottom. 2. Check on `Use auto-import` on the `Import Project from Gradle` dialog. Select JDK 1.8 in the `Gradle JVM` option. Then click `OK`. 3. IntelliJ will open the project and start gradle syncing, which will take several minutes, depending on your network connection and your IntelliJ configuration 4. After the syncing finished, select `Gradle` -> `Tasks` -> `build`, and then double click `build` option. # Running ## Running a Private Testnet ### Running a full node * In the Terminal ```bash ./gradlew run ``` * Use the executable JAE ```bash cd build/libs java -jar java-tron.jar ``` * In IntelliJ IDEA 1. After the building finishes, locate `FullNode` in the project structure view panel, which is on the path `java-tron/src/main/java/org.tron/program/FullNode`. 2. Select `FullNode`, right click on it, and select `Run 'FullNode.main()'`, then `FullNode` starts running. ### Running a Witness Node * In the Terminal ```bash ./gradlew run -Pwitness=true ```
Show Output ```bash > ./gradlew run -Pwitness=true > Task :generateProto UP-TO-DATE Using TaskInputs.file() with something that doesn't resolve to a File object has been deprecated and is scheduled to be removed in Gradle 5.0.

* Use the executable JAE ```bash cd build/libs java -jar java-tron.jar --witness true ``` * In IntelliJ IDEA
Open the configuration panel: ![](docs/images/program_configure.png)
In the `Program arguments` option, fill in `--witness`: ![](docs/images/set_witness_param.jpeg)
Then, run `FullNode::main()` again. ### Running multi-nodes To run TRON on more than one node, you need to specify several seed nodes' IPs in `config.conf` in `seed.node.ip.list`: For private testnet, the IPs are allocated by yourself. ## Running a local node and connecting to the public testnet ### Running a Full Node It is almost the same as that does in the private testnet, except that the IPs in the `config.conf` are officially declared by TRON. ### Running a Witness Node It is almost the same as that does in the private testnet, except that the IPs in the `config.conf` are officially declared by TRON. # Quick Start Read the [Quick Start](http://wiki.tron.network/en/latest/quick_start.html). # Community * [Slack](https://join.slack.com/t/tronfoundation/shared_invite/enQtMzAzNzg4NTI4NDM3LTAyZGQzMzEzMjNkNDU0ZjNkNTA4OTYyNTA5YWZmYjE3MTEyOWZhNzljNzQwODM3NDQ0OWRiMTIyMDhlYzgyOGQ) * [Telegram](https://t.me/tronnetworkEN) # Links * [Website](https://tron.network/) * [Documentation](https://github.com/tronprotocol/java-tron) * [Blog](https://tronprotocol.github.io/tron-blog/) * [TRON Wiki](http://wiki.tron.network/en/latest/) # Projects * [TRON Protocol](https://github.com/tronprotocol/protocol) * [Wallet Client](https://github.com/tronprotocol/wallet-cli) * [Wallet Web](https://github.com/tronprotocol/wallet-web)
