How can I traverse the blocks of transactions in hyperledger fabric

Question

I want to get a list of all transactions in the ledger. I want to do this using chaincode. Is there any API that will help me do this?

Answer 1

For hyperledger fabric you can use query system chaincode and you can query starting from block 0 to block H where H is the ledger height that you can obtain using the QSCC call GetChainInfo.

Hope this helps!

Traversing through the Blockchain will be complex. An easy way to get the list transactions from the World State. The world state holds the current value of the attributes of a business object as a unique ledger state so it's easier than traversing through the Blockchain.
