.
Layer 1: Overview of Blockchain Diversity
There are over 1,000 active blockchains, each with unique strengths and weaknesses.
Ethereum and Solana are highlighted as Layer 1 blockchains with distinct features.
Layer 2: Introduction to Layer 2 Protocols
Layer 2 protocols aim to enhance decentralized networks' efficiency without compromising security or decentralization.
Examples of Layer 2 tokens like MATIC, IMX, ARB, OP, and LRC are mentioned.
Layer 3: Types of Layer 2 Scaling Solutions
Layer 2 encompasses various solutions such as sidechains (e.g., Polygon), parachains (e.g., Polkadot), ZK-rollups (e.g., Matter Labs, Starkware), and optimistic rollups (e.g., Arbitrum, Optimism).
Layer 4: Significance of Layer 2 Solutions
Layer 2 inherits security from the underlying main chain, offering higher transaction speeds and lower fees.
Specific applications can be optimized through Layer 2 solutions, improving user experiences.
Layer 5: Considerations and Other Layer 2s
Potential drawbacks include liquidity shifts and inheriting vulnerabilities from Layer 1 networks.
The article briefly mentions the Bitcoin Lightning Network as a Layer 2 solution for Bitcoin.
