README.md

build

  • Get source
$ go get -u github.com/cendhu/fetch-block
  • Get govendor
$ go get -u github.com/kardianos/govendor
  • build
$ cd $GOPATH/src/github.com/cendhu/fetch-block/src

Edit config

  • Edit config.yaml for peer, msp, tls
peer:
    #id denotes the name of peer
    id: peer0
    #event-address denotes the ipaddress-of-peer:eventPort.
    #Each peer's eventhub listen on port 7053 which is the default
    #port given in fabric/sampleconfig/core.yaml
    event-address: peer0.org1.example.com:7053
msp:
    #path contains the absolute path to the msp configuration files such
    #as key, cacerts, rootcerts. For dev mode, use peer0-msp-for-dev
    path: /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp
    #localMspId denotes the MSP identity. For dev mode, use DEFAULT instead
    #of Org0MSP
    localMspId: Org1MSP
tls:
    #disable tls for dev mode
    enabled: false
    cert:
        file: /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/tls/server.crt
