Layer 1
The base blockchain protocol (e.g., Bitcoin, Ethereum, Solana). Layer 1 solutions focus on improving the underlying blockchain itself.
Why It Matters
Layer 1 refers to the base blockchain protocol, where transactions and operations occur directly. Recognizing Layer 1 is significant for understanding the foundational structure of cryptocurrency networks and their scalability.
Example
For instance, Bitcoin and Ethereum are both Layer 1 blockchains that handle all transaction processing independently. Any changes directly affect how these networks function and can impact overall user experience.
Beginner Context
For beginners, grasping the concept of Layer 1 helps you appreciate the foundation of a cryptocurrency. Understanding how these systems work lays the groundwork for exploring more advanced topics like Layer 2 solutions.
