This repository contains a proof of concept for a sharding implementation on Ethereum by Vlad Zamfir. The project was built during ETHBerlin, over 2 days, and should not be considered final nor production grade. There are probably major bugs/issues.
The dependencies of the simulation (run with python simulator.py), are satisfied by this Dockerfile:

I build it with sudo docker build --tag py3web3mpl . , then run the container from the ethshardingpoc repo, mounting it as a docker volume with the command:
sudo docker run -it --net=host --env="DISPLAY" --volume="$HOME/.Xauthority:/root/.Xauthority:rw" --volume "$(pwd)":/ethshardingpoc py3web3mpl
Note that it uses X11 to display matplotlib, so please use it at your own risk, maybe by running the simulation in the container:
cd ethshardingpoc && python simulator.py
