-- This project aims to be a full port of the original C# `NEO project <https://github.com/neo-project>`_
-- Run a Python based P2P node
-- Interactive CLI for configuring node and inspecting blockchain
-- Compile, test, deploy and run Smart Contracts written in python or any Smart Contract in the ``.avm`` format
-- `NEP2 <https://github.com/neo-project/proposals/blob/master/nep-2.mediawiki>`_ and `NEP5 <https://github.com/neo-project/proposals/blob/master/nep-5.mediawiki>`_ compliant wallet functionality
-- RPC Client
-- RPC server
-- Notification Server ( for viewing transfers of NEP5 tokens )
-- ``Runtime.Log`` and ``Runtime.Notify`` event monitoring
