Pi Network is a blockchain mining project based on mobile devices, founded by a team of Stanford University doctoral students in 2019. Its core innovation lies in achieving low-energy mining through the Stellar Consensus Protocol (SCP). As of the beginning of 2024, the global registered users of this project have exceeded 45 million, with an average of over 8 million daily active mining users. The user base covers more than 230 countries and regions. Compared with the traditional Proof of Work (PoW) mechanism, Pi’s mining energy consumption is reduced by up to 99.99%. Users only need to click once a day to participate. This nearly zero-cost participation model is the key factor for its rapid expansion. According to data from the mobile application analytics platform SensorTower, the Pi Network application has been installed over 100 million times on the Google Play Store and has remained among the top five financial application downloads in Southeast Asia for 18 consecutive months.
The growth momentum of this project mainly comes from its multi-level social promotion mechanism and ecological construction. Pi Network adopts an invitation-based viral growth model. Each user can form a security circle of up to 5 people. When the number of invited people reaches 10 or more, a 25% mining rate bonus can be obtained. This model enabled the project to achieve an average monthly user growth rate of 12% in 2023, especially in emerging markets such as Indonesia and Vietnam, where the peak number of new users per day once reached 150,000. In terms of ecological applications, over 200 DApps have been deployed since the mainnet was launched, covering areas such as e-commerce, gaming, and social networking. Among them, the Pi Mall e-commerce platform achieved a GMV of 12 million US dollars in the fourth quarter of 2023, and the number of merchants supporting Pi Coin payments exceeded 120,000.
Economic model design is also an important engine for promoting growth. Pi Network adopts a three-stage issuance mechanism: the first stage is free mining, the second stage is the issuance of 100 billion tokens on the testnet, and the third stage is the gradual halving and release on the mainnet. The current circulation volume is approximately 29 billion Pi, and the inflation rate is controlled within 5%. It is worth noting that the project controls the proportion of real users through the KYC authentication mechanism. The global proportion of users who have completed KYC authentication has reached 58%, among which the authentication pass rates in countries such as the Philippines and Nigeria exceed 75%. Although this strict identity verification led to a 35% loss of users, it effectively enhanced the value density of the network.
Despite its rapid growth, Pi Network still faces many challenges. The mainnet transaction throughput is currently limited to 50 transactions per second, which is significantly lower than the 30,000 transactions of Ethereum. In terms of regulatory compliance, the US SEC has listed similar mobile phone mining projects as key objects of observation. In 2023, a total of four similar projects were sued. Community research shows that users’ satisfaction with the mainnet transaction speed is only 65%, but their long-term value belief index for the project remains at 82 points (out of 100). According to the assessment of the Stanford Blockchain Research Center, if Pi Network can solve the scalability problem and be listed on mainstream exchanges in 2024, it is expected to enter the top 50 cryptocurrencies by market capitalization.
