Clone the fetch-block repo to $ $GOPATH/src/github.com/hyperledger/fabric/ using git clone https://github.com/cendhu/fetch-block
To compile the fetch-block tool, run the following command
$ cd fabric/fetch-block
$ go build
If compilation fails, make sure that fabric/ is placed in $ $GOPATH/src/github.com/hyperledger/fabric
After successful compilation, we can run the tool using $ ./fetch-block
Default configurations are given in config.yaml. Update config file as per the need. Make sure that the peer and fetch-block use the same MSP configuration.
When we start executing transaction on blockchain, each block is stroed in a file (with name ChannelId_blk#.json) as JSON format. In order to collect read/write set for each transaction, please replace fabric/events/producer/eventhelper.go with fetch-block/events/producer/eventhelper.go and recompile peer.
Refer to https://blockchain-fabric.blogspot.in/ for understanding the block structure.
