Re: a doc describing data flow is needed

meng <qsmeng@...>

Hi Baohua,
   Yes, that document is really needed. I am here waiting for that.  
   I know one github project
   There should be one short chapter describing the whole dataflow with some details on main api/function used. after this it is easy to read other chapter.
   Thank you.
  Best regards,

hi meng

For a quick answer:
1. peer node will use the ProcessProposal() method (see core/endorser/endorser.go) to handle the proposal.
2. orderer will use the Broadcast() method (see orderer/server.go) to handle the tx.

Maybe we need to add more details in the coming documentation.

Hi Baohua,
  Thank you very much for the dataflow. It helps me a lot.
  Further, if there exist answer to the following questions, that would be great! 
  1. APP/SDK use what api/function to form tx proposal and use what api/function to send tx proposal to peer, 
   2. peer use what api/function to receive the tx proposal and use what api/function to deal with the received tx proposal, and do what work on the proposal.
  3. similar questions for other steps.
  Maybe I expect too much.
  Thank you again.
  Best regards,

Hi everyone,
  The  fabric is more complex than permissonless platforms, like Ethereum, Bitcoin.   As there is no detailed document describing the fabric, people aiming to modify fabric code has to  read the source codes. This is also difficult.
  It is better if someone could provide a document describing  in detail the data flow from one component to another component in the following procedure: client application invoke a transaction, and finally query the state after the transaction.  Here "component" refers to client application, ledger, and something like.
 Thank you.
