Why is Ethereum facing scalability issues?
Main Reason Why The Ethereum Blockchain Has Difficulty Scaling
1 Discussion
The primary cause of Ethereum's scalability issues is that each node in the network must process each transaction. Remember that nodes are responsible for validating the miners' work. They play an important role in the network because they are the primary check on miners who choose to act maliciously. Similarly, each node maintains an accurate copy of the current network state, eliminating the need for a third party to confirm the balance of each account and smart contract. Simply put, the more transactions that occur on the network, the more work that nodes must perform. This work is not easy; node operators incur high fixed costs to purchase the equipment, and setting up and maintaining a node requires a high level of technical know-how.
