Horizontal shard scaling is a method used to enhance the performance and capacity of blockchain networks. It involves splitting the network’s data and workload into smaller, manageable pieces, called shards. Each shard operates independently and can process transactions simultaneously, allowing for greater throughput.This approach addresses the limitations of traditional blockchain systems, which often struggle with scalability as the number of users and transactions increases. By distributing data across different shards, the network can maintain efficiency and speed despite a growing volume of activity.In practice, horizontal shard scaling allows nodes to only handle the transactions relevant to their specific shard, reducing the computational burden. This not only increases the overall capacity of the network but also minimizes latency and improves user experience.Overall, horizontal shard scaling is a promising solution for achieving high scalability in blockchains, making them more efficient and capable of supporting a larger number of transactions without compromising security or decentralization.
