I’ve written a few blog posts about setting up local networks for BitCount, BitMessage and Hyperledger Fabric, and I started out with the intent to write a similar post for Ethereum. I’ve found that for Ethereum, with the use of Make and Docker, it’s a pretty straightforward process.
The first step is to check out the Ethereum codebase and build the tools:
mkdir -p $GOPATH/src/github.com/ethereum cd $GOPATH/src/github.com/ethereum git clone https://github.com/ethereum/go-ethereum.git cd go-ethereum go install -v ./... cd $GOPATH/bin ./geth
./geth --pprof http://localhost:6060/debug/pprof/
To run unit tests, just (for example) do the following:
go test -v -cpu 4 ./eth
This is all explained in the git repo’s readme file here.
Setting up a local network is equally straightforward. You can read up on it here. I won’t go through all the details but if you’re interested in some makefiles and Docker build images just send me a note.
One interesting aspect of Ethereum is that they expose their P2P protocol, so you can use Ethereum to build your own peer-to-peer networks. This can be useful for example for building distributed services that need to run in conjunction with the Ethereum network (but don’t necessarily need to make use of the Ethereum blockchain or EVM). You can read about Etherium’s P2P capabilities here.
(This will be the subject of a future blog.)
