What if I change Chaincode state in invokeChaincode

Question

I have two chaincodes. I want to know what will happen if i change the chaincode state of one chaincode using the invokeChaincode() method from another chaincode and then calling putState() method.. Will this cause any race condition? What the best way to achieve this?

Answer 1

The chaincode state is not changed when you invoke a chaincode.. 
You can follow the below steps to achieve this:

1. Client sends transaction proposal to the peer
2. Peer simulates transaction sign the results and put them into signed transaction proposal
3. Client has to repeat step #2 based on expected endorsement policies
4. Once client collected enough endorsements he send them to the ordering service
5. Ordering service cuts the block and order all transaction
6. Block delivered to the peers
7. Peer validates and eventually commits the block
