Highly Available Ethereum Nodes with N-version design

As with all software, Ethereum nodes are exposed to faults in their underlying execution stack. Unstable execution environments can disrupt the availability of blockchain nodes' interfaces, resulting in downtime, and losses for service providers and users. This talk introduces the concept of N-Version nodes. This type of configuration relies on simultaneous execution of different Ethereum clients, in the line of Avizienis' N-Version programming vision.
