Build Status License Maven Central Sonatype Nexus (Snapshots)

See our web site for details on the project.

Tuweni is a set of libraries and other tools to aid development of blockchain and other decentralized software in Java and other JVM languages.

It includes a low-level bytes library, serialization and deserialization codecs (e.g. RLP), various cryptography functions and primatives, and lots of other helpful utilities.

Tuweni is developed for JDK 11 or higher.

Build Instructions

You need to have Gradle and Java installed.

Tuweni requires Gradle 5.0 or higher.

Java 8 should be used for building in order to support both Java 8 and Java 11 at runtime.

Clone along with submodules

git clone https://github.com/apache/incubator-tuweni.git tuweni
cd tuweni
git submodule update --init --recursive

First bootstrap and download the wrapper

gradle setup
