How to get the transaction history data in block chain?

[huhaiqing]

Could you help us how to get the transaction history data from block chain?

For example, I onced executed below transaction. transaction 1: a= 100, b=200, c=300 transaction 2: a=90, b=210, c=300 transaction 3: a= 80, b=210, c=310 ...... Now I want to get the history transaction, the blockchain should return the total ledger to us, such as a= 100, b=200, c=300 a=90, b=210, c=300 a= 80, b=210, c=310

Is there any function to be called to query the total chanincode's information?

Thanks in advance.

@huhaiqing - we do not currently store historical state information. For the key/value store (aka the state stored for each chaincode), we only store the latest value of any given key. For the "ledger" we actually store the entire list of "transactions" but they do not include the state at each point in time.

A proposal for a new ledger architecture has just been started and this is one of the requirements being considered.

Could you tell me how to get the entire list of "transaction" ? Thanks

Hi @huhaiqing

I am trying to understand the difference between what you're asking for here and in issue #1735.

It seems to me, that you're looking to retrieve a list of transactions in each block as we currently do in the REST API (see below). Could you please clarify what you're looking for? Thanks!
