How does sharding technology solve the problem of Ethereum expansion?

Solutions: 1. Process transactions in parallel; 2. Reduce the burden on nodes; 3. Improve consensus efficiency, etc.

Shashing technology solves the problem of Ethereum expansion through the following aspects:

1. Parallel transaction processing: Split the Ethereum network into multiple shards, each shard can process transactions independently. Just like expanding a busy single-lane road into multiple lanes, vehicles (transactions) can drive in parallel on different lanes instead of queuing up on one road, which greatly improves transaction processing efficiency.
2. Reduce the burden on nodes: In traditional blockchain networks, each node needs to process and store all transaction data. Sharding technology allows nodes to process and store part of the data in the shard, reducing the storage and computing pressure of a single node, allowing the network to accommodate more nodes and improve overall performance.
3. Improving consensus efficiency: Each shard has its own consensus process, and the consensus of multiple shards can be carried out at the same time. Compared with the entire network, it greatly shortens the time for reaching consensus, thereby increasing the speed of transaction confirmation and increasing the network throughput.
