Pi Network 是什麼: Blockchain Explained

Pi Network represents a significant shift in the cryptocurrency landscape, aiming to make digital asset mining accessible to anyone with a smartphone. Unlike Bitcoin, which requires specialized hardware and high energy consumption, Pi Network utilizes a lightweight consensus algorithm that leverages social connections to secure its blockchain. With tens of millions of active users known as "Pioneers," the project has evolved from a simple mobile app into a multi-layered ecosystem featuring its own browser, wallet, and decentralized application (dApp) platform.

Pi Network Origins and Development Team

Launched on March 14, 2019 (Pi Day), Pi Network was founded by a team of Stanford University graduates: Dr. Nicolas Kokkalis and Dr. Chengdiao Fan. Their vision was to create a peer-to-peer ecosystem and online experience fueled by Pi, the world’s most inclusive peer-to-peer marketplace.

The core team focused on solving the "accessibility gap" in early blockchain adoption. According to official project documentation, the founders applied their backgrounds in social computing and human-computer interaction to design a mining process that doesn't drain battery life or require technical expertise. By early 2024, the network reported over 55 million engaged users globally, making it one of the largest crypto communities by head count.

Core Technical Mechanism

Stellar Consensus Protocol (SCP)

The technical backbone of Pi Network is the Stellar Consensus Protocol (SCP), originally developed by David Mazières. Unlike Proof-of-Work (PoW), which relies on computational competition, SCP allows for fast, energy-efficient transactions by reaching consensus through a network of trusted nodes. Pi adapts this by allowing mobile users to contribute to the network's security without performing heavy calculations.

Security Circles and User Roles

Pi Network's security is built on "Security Circles"—groups of 3 to 5 trusted people built by each member. These circles form a global trust graph that helps the network determine who can be trusted to execute transactions on the ledger. Users are categorized into several roles:

• Pioneer: A mobile app user who confirms they are not a "bot" daily.
• Contributor: A user who provides a list of pioneers they trust.
• Ambassador: A user who introduces others to the network.
• Node: Users who run the Pi node software on their computers to support the underlying blockchain.

The Three-Phase Roadmap and Mainnet Transition

The project follows a structured roadmap designed to ensure stability and security before full public exposure.

Phase 1 & 2: Beta and Enclosed Mainnet

Phase 1 focused on distributing tokens and growing the user base. Phase 2, the "Enclosed Mainnet" period (2021–2024), allowed the network to run on its own live blockchain but restricted external connectivity. During this time, the network focused on "Mass KYC" (Know Your Customer) to migrate millions of users to the mainnet while preventing fraudulent accounts from claiming tokens.

Phase 3: Open Mainnet

The transition to Open Mainnet (targeted for 2024–2025) signifies the removal of the firewall, allowing Pi to communicate with other blockchains and enabling users to exchange Pi for other cryptocurrencies or fiat on external exchanges. As of mid-2024, the Core Team set specific milestones for this transition, including the requirement for 10 million Pioneers to have passed KYC and the development of 100 real-world Pi utility apps.

Tokenomics and Mining Logic

The total supply of Pi is capped at 100 billion tokens. The distribution follows an 80/20 split: 80% of the total circulating supply is allocated to the community (mined by Pioneers), and 20% is reserved for the Pi Core Team. To maintain scarcity, the network employs "halving" events, where the base mining rate drops by half every time the user base grows by a factor of 10.

Comparison of Mining Mechanisms

As shown in the table above, Pi Network prioritizes accessibility and low environmental impact, making it an entry point for users who may have been priced out of traditional mining. However, the value of the token remains speculative until the Open Mainnet is fully realized.

Market Status and Trading on Bitget

Before the full Open Mainnet launch, several exchanges listed "IOU" (I Owe You) versions of Pi. These represent a promise of the future token and are not the actual Pi tokens held in the Pi mobile app. For users looking to participate in the broader crypto market while waiting for Pi's full decentralization, Bitget offers a robust platform for trading verified assets.

Bitget is a top-tier global exchange supporting over 1,300+ coins and maintaining a Protection Fund exceeding $300 million to ensure user security. On Bitget, users can enjoy competitive trading fees: 0.01% for makers/takers in the spot market (with up to 80% discount for BGB holders) and 0.02% maker / 0.06% taker for futures. For Pioneers looking to transition their gains into established assets like USDT or BTC, Bitget provides the most secure and liquid environment.

Controversies and Risks

Despite its massive following, Pi Network has faced scrutiny. Critics often point to the long development cycle and the extensive personal data collected during the KYC process. Others have questioned the referral-based growth model, though the Core Team maintains that no initial investment is required from users, distinguishing it from typical pyramid schemes. Investors should note that until the Open Mainnet firewall is removed, the "value" of Pi remains largely theoretical in many regions.
