Polygon Launches Rio Upgrade: Near-Instant Finality and 5K TPS for Global Payments
**Polygon's Rio upgrade is now live on mainnet**, delivering major improvements for onchain payments infrastructure.
**Key Features:**
- **Near-instant finality** with zero risk of reorganizations
- **Lightweight nodes** reducing costs for validators and builders
- **Path to ~5,000 TPS** supporting higher throughput
- **One-block finality** optimizing speed and stability
**Technical Innovation:**
Rio introduces **Validator-Elected Block Producer (VEBloP)** - a new architecture where validators elect a single producer per span with stateless block validation.
**Real-World Impact:**
- Payment service providers get increased capacity
- Exchanges can reduce asset availability delays
- P2P payment apps benefit from elimination of reorgs
This upgrade represents Polygon's biggest payments enhancement to date, positioning the network as a reliable foundation for global payments and real-world assets (RWAs).
Rio marks a significant milestone in Polygon's **gigagas roadmap**, continuing the evolution of core architecture to meet enterprise-scale payment demands.
