Scaling blockchains is key for mainstream adoption. Layer 2 solutions like Lightning Network and state channels offer faster transactions without altering the core protocol. Sharding, seen in Ethereum's plans, divides the network to handle more data. Rollups, including Optimistic and ZK, batch transactions off-chain. Each has tradeoffs: security, complexity, and cost. Which is right? Dive into the tech and decide.

It's amazing to see how blockchain technology continues to evolve with solutions like Layer 2, sharding, and rollups. Each has its pros and cons, making the decision complex. Exciting times ahead for blockchain scalability! 🔗💡
