Pi Network Advances Roadmap with Protocol v19.9 Completion and v20.2 Plans
- Pi Network has completed the Protocol v19.9 migration and aims to complete v20.2 by Pi Day 2026, when node upgrades will be necessary to remain connected.
- Pi Node employs the Stellar Consensus Protocol, quorum slices, and security circles to verify transactions.
Pi Network has successfully upgraded to Protocol v19.9 as part of its current Mainnet development roadmap. According to the Pi Core Team, Protocol v20.2, the next upgrade, is expected to be completed before Pi Day 2026. The node operators have been encouraged to keep their software up to date and to follow additional instructions via the official Pi Node portal.
The most recent update is part of Phase 2 of the network’s mainnet protocol upgrades. The Core Team had already established March 1 as the deadline by which the required updates needed to be made by the operators of the Mainnet nodes. Nodes not upgraded to meet the required standards will be at risk of losing connectivity. The gradual migration strategy will keep the operation running as the technical aspects of the network change.
The Pi Network’s node system is still based on desktop software. In contrast to proof-of-work-based schemes like Bitcoin, Pi Node is based on the Stellar Consensus Protocol (SCP). Under SCP, nodes form trusted groups called quorum slices that authenticate transactions by collective agreement. The trust model combines the security circles formed by mobile miners into a larger worldwide trust graph.
Pi Network Node Participation and Testnet Development
Pi Network’s node software supports three levels of participation: Computer App, Node, and SuperNode. The Computer App interface allows users to access Pi-related services on desktop devices, including balance checks and chat functions. To become a blockchain validator, a user must apply to become a Node or SuperNode through the node interface within the software.
The applicants must install and maintain the network’s technical packages. The Core Team then uses uptime, internet reliability, device performance, past community input, and trust metrics in security circles to evaluate their eligibility. Selected participants will be required to undergo the Know Your Customer (KYC) check before assuming the roles of Nodes and SuperNodes in the Testnet.
The Testnet roadmap is divided into Selection, Revision, and Live Testnet stages. In the Selection phase, the Core Team scales participation parameters based on the data on node reliability and connectivity. In the Revision Stage, the team repeatedly tests scenarios and adjusts the consensus algorithm. At this stage, stress testing and simulation are conducted by a temporary centralized layer, which will be removed for the project to become fully decentralized.
The Live Testnet stage allows Nodes and SuperNodes to process real-world test transactions using data from security circles. This phase focuses on validating network performance under real participation conditions.
Moreover, as we reported, Pi Network marked the first anniversary of its Open Network with an updated strategy from founders Chengdiao Fan and Nicolas Kokkalis. As per the founders, the roadmap includes ecosystem token development, identity services, and artificial intelligence integration.
With the upgrade complete, the Pi token has broken out of the bearish trend. At press time, PI was trading at $0.1717, up slightly after testing support at $0.1681.
