# Blockchain Miner

A simple package to understand how blockchains work.

## Installation

```shell

go get github.com/s4m-mo/blockchainminer

```

Then, import it with...

```go

import (

	m "github.com/s4m-mo/blockchainminer/miner"

)

```




## Usage

The bulk of the API is here. More detail is on [pkg.go.dev](https://pkg.go.dev/github.com/s4m-mo/blockchainminer)

```go

package main

import (

	"fmt"

	"github.com/s4m-mo/blockchainminer/hash"

	"github.com/s4m-mo/blockchainminer/miner"

)

func main() {

	transactionString := "\nAlice->Bob->20\nBob->Charlie->10\nCharlie->Alice->5\n[PrevBlockHash]\n%v"

	m := miner.NewMiner(

		transactionString,

		hash.SHA256,

		10000,

	)

	m.SetSearchSize(100000000000)

	m.SetDifficulty(6)

	m.SetHashTimes(1)

	m.SetOutputLevel(1)

	solution, hasFound := m.ThreadedMine()

	if hasFound {

		fmt.Println("\n\n", solution, "\n", hash.SHA256(hash.SHA256(fmt.Sprintf(transactionString, solution))))

	}

}

```
