Multi-layer sharding is a scaling solution designed to enhance the efficiency and performance of blockchain networks. It involves dividing the network into multiple layers, each responsible for different functions or types of transactions.The first layer typically handles the consensus mechanism and ensures the overall security and integrity of the blockchain. The second layer focuses on executing transactions and confirming them more quickly, allowing for faster processing times.Sharding, in general, involves splitting the network into smaller, manageable parts known as shards. Each shard processes its own transactions independently, which significantly reduces the load on the entire network. By incorporating multiple layers, the system can achieve higher throughput without sacrificing security and decentralization.This approach allows the blockchain to scale effectively, accommodating more users and transactions. As transactions are processed in parallel across different layers, the overall efficiency increases, making the network more responsive and capable of handling a larger volume of activity.
