fabric v1.0 区块数据结构：
详细结构
Fabric 打开blockfile
-
1.docker exec -it peer节点名 bash , 比如：sudo docker exec -it peer0.org3.wisedu.com bash
-
2.cd /var/hyperledger/production/ledgersData/chains/chains/mychannel
-
3.注：里面的文件比如blockfile_000000可以删除： rm blockfile_000000
-
4.将blockfile拷贝出来：
#exit
#sudo docker cp 31bf8b2e6374:/var/hyperledger/production/ledgersData/chains/chains/mychannel/blockfile_000000 /home/shirly/projects
其中，b81a1d1d8064是对应peer0.org3.wisedu.com的容器ID，可根据root@31bf8b2e6374:获得
那么是不是可以先把blockfile文件拷贝出来进行修改，将/var/hyperledger/production/ledgersData/chains/chains/mychannel目录下的blockfile删除，将修改过后的拷进去达到修改区块的目的
