问题 I will ask you thought Endorsement Policy example below peer chaincode instantiate -C <channelid> -n mycc -P "AND('Org1.member', 'Org2.member')" My understanding(Promise) Org1.member or Org2.member refer to Peer. The example means that Org1.member and Org2.member should have to get the same result as instantiating mycc. Question If Org1.member and Org2.member have same chaincode, could their result be different? Are Org1.member and Org2.member refer to one peer of Organization? (2-1. If so,

问题 I am having HLF network with two orgs (one peer each) and 3 order nodes with order type as a raft. For the first org joining and the peer, updates work without any problem, but for the second org I am getting some troubles in the peer update Here is the command i've used for the peer update peer channel update \ -o orderer1.base.order:7050 \ -c basechannel \ -f ./channel-artifacts/BaseRightOrg.tx \ --tls \ --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations

问题 I'm using fabric tools provided for composer to deploy fabric network as it deploys 1 peer, 1 orderer, 1 couchdb, & 1 fabric-ca. I am able to install chain code on peer but instantiation fails with following error. I am using command on fabric-peer. peer chaincode instantiate -o orderer.example.com:7050 -C composerchannel -n test -l node -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' Error: could not assemble transaction, err Proposal response was not successful, error code 500, msg

问题 I have a single-org setup running with one Fabric CA. CA Server is running with MySQL. I'm using NodeSDK to connect and issue transactions to chaincode. I'm able to set Country, State, Locality, Organisation and Organisation Unit attributes for the peers and orderers. However, when I register and enroll "users" with the Fabric, not all attributes are being set. Only the Common Name and Organisation Unit attributes are set as seen from the certificate file. Following is my snippet for

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. You would have to create a query to select all the assets then check the length of the results. For example with the Basic Sample Network: query selectAssets {

问题 I've been experimenting with Hyperledger Fabric, deployed over 2 VirtualBox Ubuntu images with docker swarm. But I have some issues when it comes to the Composer installation. 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
