My main goal of the "Part 4 post is to have one section on the

stratum protocol to the blockchain-to-peer protocol. We use the extended Blockchain network (extended Bitcoin networks) to refer to all the overall network structures that contain blockchain-to-peer protocols, mining pool mining protocols, stratum protocols, and other protocols that link blockchain system components.6.2 Node types and division of laborAlthough each node in a blockchain peer-to-peer network is mutually equivalent, each node may have a
