Validators currently expose a gRPC endpoint for clients to access the Libra blockchain, and the Libra Core team is interested in receiving feedback from the developer community about gRPC. For example, is gRPC easy to work with? Would you prefer JSON-RPC, REST, or something completely different? What APIs would be valuable for your use case? What API endpoints have been valuable in other blockchain projects?
Please provide your feedback and let us know 1) which API protocol you would like an endpoint on nodes and 2) what use cases you are trying to support. Thank you for your input and we hope to learn more about how to serve the community!
