Abstract: A novel computing appliance uses network-bound listening events to enable automated peer discovery to establish secure connection tunnels to a peer-to-peer (P2P) blockchain network. The appliance employs a zero-trust framework, ensuring secure and reliable communication between peers which creates a native, zero-trust P2P network between all nodes. By automating P2P networking for blockchain nodes through the preconfigured appliance, operators are able to connect and participate in specific blockchain environments, from an infrastructure level, with little to no experience or technological knowledge, improving the scalability and decentralization of blockchain networks.
