#以太坊行情技术解读 【⛓️ From the Perspective of Technology Stack: The Two Layers of the Crypto Ecosystem】

If we imagine the crypto world as a layered system, each layer has its own tasks. The bottom layer is Bitcoin, and the upper layer is stablecoins—they function like complementary roles, each doing its part.

**The role of Bitcoin: The Basic Settlement Layer**
Bitcoin is like the hardware of the system. Its core responsibility isn’t speed, but ensuring data cannot be tampered with and that ownership of value is absolutely secure. This forms the trust foundation of the entire crypto world. Even if transactions are slower, that irreversible nature and decentralization cannot be replaced by anything else.

**The role of stablecoins: The Application Efficiency Layer**
Stablecoins like USDD serve another purpose—they provide usable liquidity on top of a secure foundation. They shield users from the volatility of underlying assets, enabling DeFi, payments, and trading applications to operate in a stable "environment." Developers and users can work more efficiently on this layer.

**The Power of Division of Labor**
The benefits of this layered approach are clear:
- Bitcoin focuses on ultimate security and consensus, without compromising for speed
- The stablecoin layer concentrates on optimizing liquidity and cross-chain applications
- The entire ecosystem forms a trust chain: security at the bottom seamlessly transmits utility upward

**What’s the Next Key Layer?**
The current question is—what’s missing from the tech stack? Is it decentralized identity authentication, data privacy protection, or standardized compliance access solutions? Each option relates to the next development step of crypto finance. What’s your view?
