Blockchain By Example

Option 1 – editing the Ethereum client code

To explore this option, you'll need to do some Golang hacking! Don't worry; there's nothing complex.

In Geth's code (the consensus.go file at; https://github.com/ethereum/go-ethereum/blob/master/consensus/ethash/consensus.go), there is a function called CalcDifficulty that represents the difficulty adjustment algorithm. It returns the difficulty that a new block should have when created, given the parent block's time and difficulty. To fix the difficulty, we need to fix the returned value as follows:

func CalcDifficulty(config *params.ChainConfig, time uint64, parent *types.Header) *big.Int {    return big.NewInt(1)}

Afterwards, compile your new Geth client following the instructions presented in the ...
