nile-testnet is a project for developers to quickly access the tron nile testnet and use the tron nile testnet.

Nile Testnet status is Tron's Nile testnet official website. You can find resources for quick access to the Nile testnet.

Nile Testnet faucet is the faucet for the Nile Testnet. You can claim test coins on this page.

Nile Testnet proposal status You can view the nile proposals opening situation.

Nile Testnet proposal plans You can view the nile proposals discussions and plans.

Clone the repo and switch to the master branch

$ git clone https://github.com/tron-nile-testnet/nile-testnet.git
$ cd nile-testnet
$ git checkout -t origin/master

then run the following command to build nile-testnet, the FullNode.jar file can be found in nile-testnet/build/libs/ after build successfully.

$ ./gradlew clean build -x test

Make sure you operate on Linux or MacOS operating systems, other operating systems are not supported yet.

Requires 64-bit version of Oracle JDK 8 to be installed, other JDK versions are not supported yet.

Requires 64-bit version of JDK 17 to be installed, other JDK versions are not supported yet.

Get the nile testnet configuration file: nile_testnet_config.conf.

Minimum:

• CPU with 8 cores
• 16GB RAM
• 150GB free storage space

Recommended:

• CPU with 16+ cores
• 32GB+ RAM
• High Performance SSD with at least 200GB free space
• 100+ MB/s download Internet service

Full node has full historical data, it is the entry point into the TRON network, it can be used by other processes as a gateway into the TRON network via HTTP and GRPC endpoints. You can interact with the TRON network through full node：transfer assets, deploy contracts, interact with contracts and so on. -c parameter specifies a configuration file to run a full node:

Memory Tuning

• For 16 GB RAM servers: JDK 8 use -Xms9G -Xmx12G; JDK 17 use -Xmx9G.
• For servers with ≥32 GB RAM, suggest setting the maximum heap size (-Xmx) to 40 % of total RAM.
