$PI Pi Network Protocol V20.2 Core Features (Launch Date: 2026.3.12)

1. Underlying Architecture and Node Upgrades

- Full Mainnet Transition: Shutdown of Testnet2, complete shift to mainnet production environment
- Mandatory Node Upgrades: Nodes that do not upgrade will be disconnected from the mainnet
- Automated Upgrade Mechanism: The core team will no longer manually intervene; protocol executes automatically
- Performance Leap: Significant improvements in transaction throughput, response speed, and stability
- Security Reinforcement: Multi-layer protection, enhanced consensus, and attack resistance

2. Core Functions and Ecosystem Capabilities

- Open Network Activation: New toggle in the app supporting interoperability with external chains/systems
- Dual Balance Display: Mainnet balance + pending migration/verification balance, transparent asset status
- Cross-Chain Bridge Integration: Supports interoperability with assets on chains like Stellar, enabling cross-chain liquidity
- Pi DEX Launch: Built-in decentralized exchange supporting P2P trading and AMM market making
- Rust Smart Contracts: Supports complex on-chain logic, paving the way for DeFi and DApps
- KYC Verifier Rewards: Launch of review rewards to accelerate KYC and mainnet migration
- Mainnet Migration Speed-up: Complete unlocking and migration for all KYC-verified users

3. Economic and Governance Upgrades

- Fixed Pricing Mechanism: Economic model embedded into the protocol, reducing manual intervention and uncertainty
- On-Chain Value Circulation: Pi shifts from static balances to a tradable, liquid, and stakable store of value

In summary: V20.2 marks a milestone for Pi, transitioning from the “testing phase” to a “mature public chain,” with full implementation of the four core capabilities: mainnet, DEX, cross-chain, and smart contracts.
