ABSTRACT
Layer 2 blockchain solutions improve scalability and transaction efficiency while preserving the security and decentralization of base blockchains like Bitcoin and Ethereum. These solutions enable faster and more costeffective transactions, making them crucial for Decentralized Applications (DApps). This paper explores the fundamentals of Layer 2 technology, its various implementations, and its impact on blockchain ecosystems. It also examines the benefits and challenges of these solutions, emphasizing the different approaches adopted across blockchain networks.
Layer 2 solutions address blockchain scalability issues by reducing the reliance on the main blockchain, which traditionally suffers from slow transaction speeds and high costs. Unlike Layer 1 solutions that alter the core blockchain infrastructure, Layer 2 solutions process most transactions offchain, using the main blockchain primarily for security and final settlements. By reducing congestion, Layer 2 solutions ensure smoother operation for blockchain applications, allowing them to reach their full potential in real-world use cases such as decentralized finance (DeFi), gaming, and enterprise solutions.
Key Words: Layer 2 Blockchain Solutions, Blockchain Scalability, Decentralized Applications (DApps), Off-chain Transactions, Rollups (Optimistic and Zero-Knowledge), State Channels, Sidechains, Transaction Throughput, Latency Testing, Interoperability Issues, Security Vulnerabilities, Regulatory Compliance, Decentralization Risks, Smart Contract Security, Cross-chain Communication
