What is Pi Network (PI)?
Pi Network (PI) is a social cryptocurrency and developer platform that lets ordinary people earn digital currency through a smartphone app. Pi Network states that its aim is a widely distributed currency used for real-world goods and services rather than purely speculative trading.
Pi Network was founded by Dr. Nicolas Kokkalis and Dr. Chengdiao Fan, both holders of doctoral degrees from Stanford University, and the project is managed by Social Chain Inc. The Pi app launched on March 14, 2019 according to the project, and its mobile-first approach, which does not require specialized hardware, helped drive early adoption.
Pi Network moved to its Open Mainnet on February 20, 2025 according to the project's announcement, removing the firewall that had blocked external connectivity and allowing PI to be transferred outside the Pi ecosystem.
How does Pi Network reach consensus?
Pi Network operates on the Stellar Consensus Protocol and a Federated Byzantine Agreement, in which participants reach agreement by trusting specific groups of chosen peers. This Pi Network design avoids the large-scale computational competition associated with proof-of-work systems.
Pi Network security is maintained through a global trust graph assembled from security circles, small user groups whose members vouch for one another. Earning in the Pi app is a reward allocation tied to participation rather than a process that consumes the phone's computing resources.
What roles and ecosystem does Pi Network have?
Pi Network users participate in four primary roles as pioneers, contributors, ambassadors, or nodes, each supporting the network's decentralization and trust structure. The Pi Network distribution model is described as rewarding consistent engagement and network growth rather than financial wealth or computing power.
The Pi Network ecosystem includes a native wallet, a dedicated browser, and a platform for decentralized applications. The PI token is used for peer-to-peer exchange and transaction fees, and is also positioned as a means of paying for goods and services within the ecosystem.
Pi Network lists a maximum supply of 100 billion PI according to the project whitepaper, and mined balances are migrated to mainnet in phases, starting with users who have completed KYC identity verification.
What are the strengths and risks of Pi Network?
Commonly cited strengths of Pi Network include a low barrier to entry, a large user base, and a consensus design that does not require competing mining hardware. The stated focus on practical payments and an application ecosystem is also noted as a defining characteristic of Pi Network.
Balanced against that, observers of Pi Network point to the long enclosed mainnet period, transfer restrictions tied to KYC and mainnet migration progress, the effect of scheduled unlocks on circulating supply, and the fact that real-world usage is still being established. Details of Pi Network such as circulating supply and unlock schedules are best verified directly in official documentation and on aggregators such as CoinGecko.
