how exactly blocks are created in hyperledger fabric

Question

I am going through hyperledger fabric V1.0. Need to know the internals of hyper-ledger.

1) How and where the blocks and transactions are saved in hyperledger internally.

Answer 1

Kostas answer for one and two are phenomenal. For question 3, the documentation has come along pretty far since March and the best setup I have found is here https://github.com/hyperledger/fabric/blob/master/docs/source/getting_started.rst It gives explicit instructions on switching to couchdb for the endorsers, a good explanation of the configuration files and tools and the script for the chaincode deployments serves as a great scaffolding to add your own deployments to. Another hidden gem in there is the docker-compose-e2e-template file which includes the certificates authorities. Pay close attention to the fact you need to edit that file, not the docker-compose-e2e.yaml file to be included when you do a./network_setup up. Also, if you look at the top of ./network_setup.sh it has the reference to the "copied" docker-compose-e2e.yaml that is commented.
