You can follow this tutorial to
download blocks from the blockchain on the peer.
1. Connect to the peer container and setup membership variables:
$ docker exec -it peer0.org1.example.com bash root@aedfd08717a5:/opt/gopath/src/github.com/hyperledger/fabric# cd root@aedfd08717a5:~# export CORE_PEER_LOCALMSPID=Org1MSP root@aedfd08717a5:~# export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp
2. Get information about the blockchain of the "mychannel" channel:
root@aedfd08717a5:~# peer channel -c mychannel getinfo Blockchain info: {"height":1, "currentBlockHash":"X9wYVYmoD4HoXkWVlm1n2n9L2gJEa2PYa8AwAN9CdA4="}
3. Get information about the blockchain of the "mychannel" channel:
root@aedfd08717a5:~# peer channel -c mychannel fetch 0 first.block root@aedfd08717a5:~# ls -l -rw-r--r-- 1 root root 9235 Apr 1 02:52 first.block
As you can see, the channel only has one block, the genesis block. We downloaded a copy to a file.
