Lightweight Shard Consensus refers to a method used in blockchain networks to enhance scalability and efficiency. Instead of processing all transactions on a single chain, it divides the network into smaller segments called shards. Each shard operates independently, allowing for parallel processing of transactions.In this model, consensus mechanisms are applied within each shard rather than across the entire network. This reduces the overall workload and speeds up transaction times while maintaining security and decentralization.Lightweight Shard Consensus is designed to ensure that nodes in each shard can reach agreement quickly and effectively, often using less resource-intensive algorithms. By limiting the number of transactions that need to be validated at once, this method minimizes latency and makes the network more responsive.Overall, this approach aims to improve the user experience by increasing the throughput of the network while still protecting it from fraudulent activities.
