问题 I am trying to build a Block chain application for distributed image sharing and copyright protection. I am using image as an asset. So now I want to upload an image on Hyper ledger Composer playground. How can I do that? 回答1: You can store your file data into the IPFS. IPFS is a protocol and network designed to create a content-addressable, peer-to-peer method of storing and sharing hypermedia in a distributed file system. For IPFS I recommend you to follow the link In your application, In

问题 I want to write a query in HyperLedger Composer that returns me the count of assets that I have in hyper ledger. I have thousands of records. I don't want to fetch them all and calculate count. Data transfer will be slow I want the query to return the count. 回答1: Unfortunately there is no count in the composer query language.

Network Setup: Host1: Orderer, Peer1.Org1, Peer2.Org1, CLI Host2: Peer1.Org2, Peer2.Org2 When it comes to the Fabric setup everything appears to be ok. I'm able to start the network, join the peers from the second host, and update the anchor peers (one for each organisation). The Composer installation starts with
