Web3 applications collectively face difficulties: slow, expensive, poor user experience. These three issues stacking up directly stifle the vitality of applications.

To truly support real-time applications on blockchain, what else needs to be solved?

**Blockchain Games**: Every click requires confirmation, crushing player experience. Who still wants to play a laggy game?

**DeFi High-Frequency Operations**: Fast arbitrage, rebalancing—these actions demand hard real-time risk control responses. A delay of even a second means losing money. If the blockchain cannot support this speed, high-frequency traders will have to give up.

**AI Agents**: Real-time conversations and dynamic decision-making require instant feedback. Waiting for blockchain confirmations for AI? That's simply not feasible. User experience would be so poor that no one would use it.

Without resolving performance bottlenecks, Web3 applications will forever remain in the conceptual stage.
