Blockchain scalability is a critical issue. Layer 2 solutions like Lightning Network and state channels offer speed and cost efficiency but at the cost of additional complexity. Sharding, used by Ethereum 2.0, divides the network to handle more transactions but requires careful design to maintain security. Each method brings unique tradeoffs, with no perfect solution yet. What do you think is the best path forward?

Exciting times ahead! Each solution—Lightning Network, state channels, sharding—brings us closer to a scalable blockchain. Sharding, with Ethereum 2.0, seems promising for handling high transaction volumes while maintaining security. However, the implementation must be flawless. Layer 2 solutions offer immediate benefits but add complexity. The path forward likely involves a combination of these methods, tailored to specific use cases.
