Node network architecture
P2P network
Each computer/server running HPB's public chain program represents a single node in a connected Peer-to-Peer (P2P) network.
Nodes provide network connection, database storage and processing capabilities such as mining and consensus, as well as executing smart contracts.
4 types of node
4 different types of node support HPB's MainNet:
High-Performance Node (hnode) These are elected from candidate nodes for the job of processing and verifying transactions and writing blocks to the chain.
Pre-Node (pnode) Also known as "candidate" nodes, these nodes are available for work and voted in by HPB's community.
Boot Node (bnode) A boot node's job is help a new node to access the network and make the connection with other nodes in the network.
Sync Node (snode) Sync nodes synchronize the network database and do not participate in elections and block generation.
Both High-Performance and candidate node servers must have a BOE accelerator card installed.
