Abstract

Develop a connector that provides both synchronous and asynchronous modes of interacting with a running Hyperledger Besu node. The connector would act as an interface between an enterprise application and the Hyperledger Besu node for data ingestions and it could provide event subscription options.

The scope of the project would also include an end-to-end test on a sample network.
