Pi Network allows tens of millions of users to tap a button in a mobile app once per day to receive PI tokens. The daily tap confirms that the user is a real, active human and keeps the user eligible for token rewards.

The network uses the Stellar Consensus Protocol, a Federated Byzantine Agreement system. Each participant selects a set of trusted nodes, called a quorum slice. Overlapping trust relationships form a global trust graph that the protocol uses to reach agreement on transaction validity. The process does not involve computational work or electricity consumption.

Pi assigns four participation roles. Pioneers are users who open the app daily and tap the button, confirming presence and maintaining reward eligibility. Contributors add trusted individuals to Security Circles, supplying trust data for the global graph. Ambassadors refer new users to the network and may receive a higher earning rate. Nodes run software on computers that perform consensus calculations and validate transactions, using the trust graph created by mobile users.

The token emission schedule is designed to decline over time, with the base rate halving at user milestones and decreasing as the network scales. Earnings are adjusted by multipliers related to role and contribution. Critics note concerns about reliance on trust relationships for security, the degree of decentralization of the node network, and referral mechanics that resemble multi‑level marketing. The project’s centralization and the maturity of its node infrastructure remain under discussion. The token’s ultimate value depends on the network’s ability to deliver utility and achieve decentralization, and the information reflects the project’s status as of June 28, 2026.
