Scalability Roadmap

Splendor’s scalability plan includes several phases:

1. Current (Tokio): ~1,000 TPS with 2-second block times
2. Next Update: Implementation of parallel transaction processing
3. Future Release: Layer 2 solutions with rollup support
4. Long-term: Sharding implementation for horizontal scaling

This technical specification represents the current state of Splendor v3 (Tokio) and is subject to enhancements through protocol governance.
