Ethereum node as a service
-
Running an Ethereum node as a service can be profitable for those who are able to scale their infrastructure. Those who offer this service can charge higher fees than those who do not, which can lead to a larger share of the network’s transactions. Additionally, those running nodes can help to secure the network by validating blocks and committing transactions.
