docker inspect --format='{{index .RepoDigests 0}}' <image_name>

The output must show the image digest, and then you can copy that output in the FROM tag inside the Dockerfile

Test

If you want to run the Nethermind or Ethereum Foundation tests, then:

dotnet build Nethermind.sln -c Debug
dotnet test Nethermind.sln

dotnet build EthereumTests.sln -c Debug
dotnet test EthereumTests.sln

IDE

• JetBrains Rider
• Visual Studio Code

Contributors welcome

At Nethermind we are building an open source multiplatform Ethereum client implementation in .NET Core (running seamlessly on Linux, Windows and MacOS). Simultaneously our team works on Nethermind Data Marketplace and on-chain data extraction tools and client customizations.

Nethermind client can be used in your projects, when setting up private Ethereum networks or dApps. The latest prod version of Nethermind can be found at downloads.nethermind.io.
