Here’s a quick breakdown of blockchain layers and how they work together: 💠 𝐋𝐚𝐲𝐞𝐫 1 (𝐋1): Layer 1 refers to the base blockchain architecture like Ethereum, Bitcoin, or Solana. These networks handle all transactions, security, and decentralization on-chain. However, as usage increases, L1s can face issues like slow transactions and high gas fees due to their consensus mechanisms. 🌐 💠 𝐋𝐚𝐲𝐞𝐫 2 (𝐋2): Layer 2 solutions build on top of L1 to enhance scalability. L2 networks like Polygon or Arbitrum process transactions off-chain and then bundle them back into L1, reducing the load and improving efficiency without compromising security. 🚀 💠 𝐑𝐨𝐥𝐥𝐮𝐩𝐬 (𝐀 𝐓𝐲𝐩𝐞 𝐨𝐟 𝐋2): Rollups are one of the most popular L2 scaling solutions. They “roll up” hundreds of transactions into a single batch, which is then verified on the L1 blockchain. There are two main types of rollups: 𝐎𝐩𝐭𝐢𝐦𝐢𝐬𝐭𝐢𝐜 𝐑𝐨𝐥𝐥𝐮𝐩𝐬: Assume transactions are valid by default and only check them when challenged. 𝐙𝐊 (𝐙𝐞𝐫𝐨-𝐊𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞) 𝐑𝐨𝐥𝐥𝐮𝐩𝐬: Use cryptographic proofs to ensure transaction validity without needing to re-execute them on L1. Together, L1 and L2 layers (with rollups) aim to make blockchains more scalable, affordable, and accessible without compromising on decentralization or security. Exciting times are ahead for blockchain tech as these solutions mature! 🚀🔗 Cyfrin Updraft Muskan Jain LearnWeb3 Ciara Nightingale Santiago Trujillo Zuluaga Bianca Andreea Buzea Maggie Love H.E.R.
