Mana-Ethereum is an open-source Ethereum blockchain client built using Elixir. Elixir runs on the Erlang Virtual Machine, which is used for distributed systems and offers massive scalability and high visibility. These properties make Elixir a perfect candidate for blockchain network development. In the current Ethereum ecosystem, a majority of active nodes on the network are Geth or Parity nodes. Mana-Ethereum provides an additional open-source alternative. Our aim is to create an open, well-documented implementation that closely matches the protocols described in the Ethereum yellow paper.
