What Are Layer 2 Solutions in Blockchain? ⚙️ Layer 2 Solutions As blockchain networks grow, scalability becomes a challenge. Layer 2 solutions are built on top of existing blockchains to improve speed and reduce transaction costs. 1️⃣ Examples of Layer 2 Solutions: Lightning Network (for Bitcoin): Enables faster and cheaper transactions by creating off-chain payment channels. Optimistic Rollups (for Ethereum): Bundles multiple transactions into one to improve Ethereum's scalability. 2️⃣ Why They Matter: Scalability: Improve blockchain efficiency without compromising security. Speed: Faster transaction processing for high-demand applications like gaming and finance. ⚡️ Interesting Fact: The Bitcoin Lightning Network is capable of processing millions of transactions per second, a far cry from Bitcoin's base layer speed.
