I have fabric network setup with 2 organisations, install the fabcar chain code and I am able to create the transaction.

  1. I am able to get the blockchain info using the below cmd inside docker, work well. I want get blockinfo using fabric sdk is it possible? If yes, how, any example would be help full.

  1. Is it possible to get the blockhash or blockchain info using chaincode?

  2. I am creating multiple transactions it works well, just wanna know does the transaction created by user have any sequence number/none. If yes from where it is fetched.

  1. Yes, check SDK API. This can be helpful: https://fabric-sdk-node.github.io/release-1.4/Channel.html#queryBlock__anchor . It makes you query by block ID.
  2. You can use SDK too for this.
  3. Every transaction has a unique identifier ID which is the TxId, it is an hash string. Transactions does not have an index but blocks does.
