Mineplex is a distributed consensus platform with meta-consensus capability. Mineplex not only comes to consensus about the state of its ledger, like Bitcoin or Ethereum. It also comes to consensus about how the protocol and the nodes should adapt and upgrade. For more information about the project, see https://mineplex.io.
Instructions to install, start using, and taking part in the consensus are available at https://github.com/mineplexio/Plexus-Pool.
