#PI# Technical Positioning: The Core Basis of L1 Public Chain **

1. **Consensus Mechanism and Underlying Architecture**
- Pi adopts the **Federated Byzantine Agreement (FBA)** combined with the **Stellar Consensus Protocol (SCP)**, and independently optimizes it into the **PIOS consensus mechanism**, which supports high throughput and low energy consumption for transaction verification.
- Unlike traditional PoW/PoS, its mobile mining model lowers the participation threshold, aligning with the positioning of L1 public chains as a "decentralized infrastructure."

2. **Completion of the Four Core Technologies**
- **Cryptography**: Asymmetric encryption and multi-signature wallets have been implemented;
- **Consensus Mechanism**: The PIOS mechanism supports cross-chain interoperability (such as the connection between Web2 and Web3);
- **Distributed Storage**: After the mainnet is opened, a global node network will be enabled to achieve truly decentralized storage;
- **Smart Contract**: Under development, will support dApp ecosystem in the future.

### 🌐 **The Milestone Significance of Open Mainnet**
- **Global Access Opens**: On August 9, 2025, Pi Network officially enters **Phase III Open Mainnet**, removing firewall restrictions, allowing users to freely engage in P2P transactions and access external dApps and Web3 services.
- **Technical Verification**: The mainnet launch marks its upgrade from a "test chain" to a fully functional L1 public chain, capable of independently running smart contracts and decentralized applications.

### 📊 **3. Market Response and Controversies**
1. **Community Support**
- Some users believe that being classified as L1 is a "technical naming", emphasizing its equal status with Bitcoin and Ethereum (as heavily discussed in the Gate community).
- After the mainnet launch, trading volume surged, with a 24-hour increase of 10%–15%, reflecting short-term market optimism.
