Let's talk about the concept of Layer 1 Crypto, because it really is the foundation for understanding the entire blockchain ecosystem.

Simply put, Layer 1 is the underlying infrastructure of blockchain networks, responsible for processing transaction validation and block creation. Bitcoin was the earliest implementation of Layer 1, pioneering decentralized digital currency. Later, Ethereum emerged, upgrading this concept by not only supporting transfers but also running smart contracts and various DApps. Today, new projects like Cardano and Polkadot are also Layer 1 protocols, attempting to solve longstanding issues like scalability and energy efficiency on top of Bitcoin and Ethereum.

Why is Layer 1 so important? Because all DeFi, NFTs, and even Web3 applications are built on these underlying protocols. Without the security and consensus mechanisms of Layer 1 (such as PoW or PoS), the applications above have no foundation. These foundational layers maintain network security through decentralization, allowing strangers to trade with confidence—something traditional finance cannot achieve.

From a market perspective, the performance of mainstream Layer 1 crypto assets varies greatly. Bitcoin's circulating market cap is currently around $1.5 trillion, Ethereum is about $280 billion, and Cardano is around $9 billion. These figures reflect the market's recognition of different Layer 1 projects—Bitcoin, as the oldest, still holds an absolute position.

Recent innovations in the Layer 1 space mainly focus on a few directions: sharding technology, sidechain scaling, improved consensus mechanisms, and increased attention to energy efficiency. Everyone is thinking about how to boost transaction throughput while maintaining security—an eternal topic.

If you want to trade these Layer 1 assets, there are many options now. Whether mainstream or emerging Layer 1 projects, major trading platforms support them all. I personally believe that understanding the role of Layer 1 is crucial for judging the entire crypto market because they are the foundation of this ecosystem.
