Ev-node is the basis of the Evolve Stack. For more in-depth information about Evolve, please visit our website.

⚠️ Version Notice: Do not use tags or releases before v1.*. Pre-v1 releases are not stable and should be considered abandoned.

Evolve supports multiple sync modes:

• Hybrid sync: Sync from both DA layer and P2P network (default when peers are configured)
• DA-only sync: Sync exclusively from DA layer by leaving P2P peers empty (see Configuration Guide)
• P2P-priority sync: Prioritize P2P with DA as fallback

The easiest way to understand how to use Evolve is by exploring our example implementation, TestApp.

Requires Go version >= 1.22.

TestApp is a CLI tool that demonstrates how to run different kinds of nodes using the Evolve framework. It serves as a reference implementation and helps you understand how to build your own Evolve-based blockchain.

To install the example testapp, simply run the following command at the root of the ev-node repo:

make install

The latest TestApp example is now installed. You can verify the installation by running:

testapp version

You can spin up a local TestApp network (powered by Evolve) with the following command:

testapp start

Evolve is the first sovereign application framework that allows you to launch a sovereign, customizable blockchain as easily as a smart contract. TestApp serves as a reference implementation to help you get started with your own Evolve-based blockchain.
