When it comes to blockchain scalability issues, this topic always revolves around the dilemma of the "Impossible Triangle." By 2026, in this cycle, we see Rollups becoming quite mature, and sharding technology also evolving. But do you know? In scenarios requiring extreme throughput, this old technology Plasma still has some tricks up its sleeve.

**Why is Plasma still worth paying attention to?**

Simply put, Plasma is not just about speed; it also aims for "wide" coverage. Its approach is somewhat similar to MapReduce in computers—building a layered sidechain tree structure, offloading complex computations and data storage to off-chain processing, and only periodically submitting the final state commitments to the main chain. What are the benefits of this? Transaction processing capacity can increase exponentially, theoretically reaching hundreds of thousands of transactions per second.

**Fraud proof mechanism is the key**

The fraud proof system introduced by Plasma is even more critical. If any node dares to submit an invalid block, any observer can submit proof to the main chain to report it. This design guarantees the system's security while maintaining scalability. That’s also why, in certain application scenarios, Plasma still demonstrates an irreplaceable technical resilience. The XPL project is a practical implementation based on this architecture.
