Scaling solutions aim to improve the performance of blockchain networks, allowing them to process a larger volume of transactions without compromising speed, security, or decentralization. These solutions can be classified into two main categories: Layer 1 solutions, which involve protocol-level changes to enhance the blockchain's capacity, and Layer 2 solutions, which operate on top of the existing blockchain to offload transactions and reduce congestion. Examples of scaling solutions include sharding, which splits the network into smaller segments; state channels, which allow for off-chain transactions; and rollups, which bundle multiple transactions into a single one for on-chain verification.
