问题 I am executing ../bin/cryptogen generate --config=./crypto-config.yaml command following build your First Network in Hyperledger Fabric tutorial. I see that the Admin and User .pem certificates are created in "signcerts" directory (in msp dir) but they are not copied in "admincerts" directory. What is the configuration to solve this? 回答1: For a workaround you can downgrade your cryptogen version to 1.4.2 as you must be having 1.4.3 version of cryptogen binary.

问题 I have a network set up that is based on the fabcar example. Customized the chaincode and the folder structure, and it all seems to compile and fire up just fine. But now, I am trying to find out whether I can use function Contract.submitTransaction() (found in invoke.ts and covered in the docs) or a more applicable function to pass somewhat more complex arguments for custom type Shipment which is based on type Car of the original example. In the example, Car is simply a flat type of string s

问题 Looking at securing confidential information in Hyperledger Composer If assets and transactions in a business network have ACL's to prevent a competitor participant (non-owner) from viewing confidential information, what access can the competitor have to assets and transactions owned by another participant? Can the competitor access the underlying Fabric ledger to view assets/transactions? Can the competitor view the transaction processing function? Can the competitor view the logs of the

问题 With consideration of existing functionality, developer productivity (assuming minimal experience in each language), support within the Fabric community, and roadmap for enhancements, is there any chaincode development language that should be preferred as the short-term and, perhaps separately, as the long-term choice? Prior question Node.js or Go for Hyperledger Fabric's chaincode development? did not address Java as an option, and does not account for recent Fabric 1.4 platform release. 回答1
