Nimbus: an Ethereum 2.0 Sharding Client

Building & Testing

Prerequisites

Please install a recent version of Facebook's RocksDB following the instructions here:

https://github.com/facebook/rocksdb/blob/master/INSTALL.md

Currently Nimbus requires the latest development version of the Nim programming language. Follow the installation steps or use choosenim.

Obtaining the prerequisites through the Nix package manager

Users of the Nix package manager can install all prerequisites simply by running:

nix-shell nimbus.nix

Build

You can build the package and run the tests using nimble test. You can run the example using nim compile --run examples/decompile_smart_contract.nim.

You can run the official Ethereum JSON tests for the EVM this way:

create a ./build directory with mkdir build in your cloned repository.

Run

nim c -r --nimcache:nimcache -o:build/test tests/test_vm_json.nim

The executable will be put in build, and nim compilation cache will use nimcache.
