Layer 2 Scaling Solutions: Technical Implementation Guide for Ethereum
Ethereum’s transition to proof-of-stake solved energy concerns but scaling remains the blockchain’s biggest challenge. With Layer 1 throughput limited to ~15 TPS and gas fees frequently exceeding $50 per transaction, Layer 2 solutions have become critical infrastructure. This technical guide explores the implementation details of major L2 scaling approaches, analyzing their trade-offs and providing practical code examples. The Layer 2 Scaling Landscape Layer 2 solutions process transactions off-chain while inheriting Ethereum’s security guarantees. The current L2 ecosystem processes over 3.2 million transactions daily across major networks, with combined TVL exceeding $45 billion. ...
