【Understand blockchain L1 and L2 in 1 minute🌟】
🌱 What are L1 and L2?
- L1 (first layer): the "foundation" of blockchain, such as Bitcoin and Ethereum.
Function: bookkeeping and data storage, but slow (like a main road with traffic jams🚗💨).
- L2 (second layer): "fast track" built on L1, such as Rollups and Lightning Network⚡.
Function: Help L1 share the pressure, transactions are faster and cheaper!
🔧 How does it work?
1️⃣ L1 is responsible for security: all transactions will eventually return to L1 for evidence storage (like depositing in a safe🔒).
2️⃣ L2 is responsible for acceleration: pack 100 transactions into 1, and then pass it to L1 (express delivery packing and dispatching📦🚚).
🌰 For example
👉 L1 = supermarket checkout counter, slow checkout queue;
👉 L2 = self-service checkout machine, 10 people scan at the same time, and finally report the bill together!
💡 Summary in one sentence
L1 is the basic big ledger, L2 is the smart assistant, working together to make blockchain faster and more cost-effective!
