The Pi node is an important part of the Pi network, allowing ordinary users to participate in the transaction verification and consensus process of the blockchain. Pi nodes run through desktop applications using the Stellar Consensus Protocol (SCP) mechanism rather than traditional Proof of Work (PoW). Nodes are divided into three participation levels: computer applications, nodes, and super nodes, each level having different responsibilities and functions. The goal of the Pi network is to gradually achieve decentralization, where in the future, users can not only verify transactions but also contribute computing resources to participate in network construction. Although there are currently no direct rewards in the Testnet phase, Pi nodes provide users with a simple way to participate in blockchain development, with reward mechanisms expected to be introduced in the future.
