Ethereum

If we want to change geth source code by our requirement , first we have to setup go-ethereum repository on our machine.

Ethereum

There are no of following changes can be done by go-ethereum source code

a) block difficulty

b) reward

c) fast mining

d) memory space changes for an unlock account and extra

There are the following step to configure go-ethereum on our local machine.

Step 1.

a) Open Terminal
b) Take clone of go-ethereum by following command
git clone https://github.com/ethereum/go-ethereum

Step 2.

  Download go compiler and installation step
   a) wget https://storage.googleapis.com/golang/go1.7.4.linux-amd64.tar.gz
   b) sudo tar -xvf go1.7.4.linux-amd64.tar.gz
   c) sudo mv go /usr/local
   d) Create .go directory in home. (It is easy to install the necessary packages without admin privillege)
      mkdir ~/.go
   e) Set up the following environment variables
      GOROOT=/usr/local/go
      GOPATH=~/.go
      PATH=$PATH:$GOROOT/bin:$GOPATH/bin

   f) Update the go command
      sudo update-alternatives --install "/usr/bin/go" "go" "/usr/local/go/bin/go" 0
      sudo update-alternatives --set go /usr/local/go/bin/go

   g) Test the golang version
      go version

   h) sudo apt-get install -y build-essential golang

Step 3.

  Last step for check , is go-ethereum configure successfully, by runing following command
  cd go-ethereum
  make geth

After successful setup of go-ethereum , we can change their source code and run the geth by following line of code

~/go-ethereum/build/bin/geth --datadir first --networkid 1100 --rpcport 8454 --port 30306 --rpcapi eth,web3,personal,miner,admin,txpool --rpc --rpcaddr '127.0.0.1' --rpccorsdomain '*' --nodiscover console

I hope this will be helpful
Thanks
