If a different chaincode deployed a world state variable is it still accessible by another chaincode

Question

Are variables in the World State access protected?

If it is not possible, how can I make a chaincode read the variables from another chaincode? I need it for my use case please help.

Answer 1

No, variables stored by some chaincode (A) can only be accessed by the same chaincode (A). So if another chaincode (B) tries to access the variable, access will be denied.

If you wanted to access such variables (because your use case requires interconnection between chaincodes) you can invoke/query chaincode A from chaincode B.
