问题 We want to invoke one of the functions from go language chaincode itself. The reason for doing so is that we want to create separate transaction blocks for some logics based on flow. For example, if we have a function named ' transferFund ' and within that, we are reading balances of two persons (let it be a function named ' readBalance '). We want 3 blocks to be created: 1 for ' transferFund ' and 2 for ' readBalance ' 回答1: To invoke another chaincode within your chaincode you can use stub
