I have a private blockchain based on EOS. I would like to know, know how to secure all access to the EOS blockchain using an account. I'm talking about access to APIs that could give information or modify the blockchain configuration.
API that changes configuration : http://localhost:8888/v1/producer/pause
API that get information :http://localhost:8888/v1/chain/get_info
So I would like to secure my blockchain, only companies that have an account in the blockchain can have access to these APIs.
