The Evolution of Layer 2s: From Idea to Reality

Layer 2 的演变：从想法到现实

The concept of Layer 2s has evolved significantly over the past decade. Initially conceived as a theoretical solution to blockchain scalability challenges, they have now materialized into fully functional networks that have transformed the on-chain landscape. Layer 2s have emerged as the driving force behind the explosive growth of blockchain applications, empowering users with faster, cheaper, and more versatile transactions.

Layer 2 的概念在过去十年中发生了显着的变化。它们最初被认为是解决区块链可扩展性挑战的理论解决方案，现在已具体化为功能齐全的网络，改变了链上格局。 Layer 2 已成为区块链应用爆炸式增长背后的驱动力，使用户能够进行更快、更便宜、更通用的交易。

The Role of Layer 2s: Enhancing Scalability and Security

第 2 层的作用：增强可扩展性和安全性

Layer 2 networks operate by leveraging the security of their parent chain, such as Ethereum or Bitcoin, while executing transactions on a separate, purpose-built blockchain. This unique architecture enables Layer 2s to process vast volumes of transactions at significantly reduced costs compared to Layer 1 blockchains. Moreover, the security of the parent chain ensures that Layer 2 transactions remain immutable and tamper-proof.

第 2 层网络通过利用其父链（例如以太坊或比特币）的安全性来运行，同时在单独的专用区块链上执行交易。与第 1 层区块链相比，这种独特的架构使第 2 层能够以显着降低的成本处理大量交易。此外，母链的安全性保证了第2层交易保持不可变和防篡改。
