Layer 2 solutions are already tackling one of the biggest issues of blockchain technology: scalability. Learn what they are and why they matter.
Layer 2 blockchains provide a solution to tackle layer 1 blockchains’ scalability
As more dapps joined the Ethereum network, the layer 1 blockchain suffered from congestion, resulting in high transaction fees. The invention of layer 2 offers a viable solution to the scaling of layer 1 blockchains.
Summary:
- Layer 1 is the underlying main blockchain architecture. Both Ethereum and Bitcoin are layer 1 blockchains.
- Layer 2 refers to the scaling solutions to reduce congestion through secondary blockchains. Examples of layer 2 chains are Optimism, Arbitrum, and StarkNet.
- Layer 2 blockchain addresses scalability through rollup technology, mainly Optimistic rollups and Zero-knowledge rollups.
Due to the unique architecture to guarantee decentralization and security, pioneer blockchains like Ethereum and Bitcoin cannot handle massive…
