Blockchain in Go

Blockchain

This work-in-progress project is writing a simplified cryptocurrency (mostly following Bitcoin) blockchain in Go.

The desire to do so is two-fold:

1. To learn more about the nuts and bolts of crypto
2. To learn more about Go!

While the result is not intended to be production-level quality nor used for actual transactions, the hope is to create enough realistic features on it to mimic the flow of real transactions.

Getting started

Clone the repository:

git clone [e-mail]:neil-berg/blockchain.git

Build the binary:

go build main.go

Use the CLI (more to come!):

./main addblock --data "Paying Jane .0005 BTC for coffee"
./main printchain

Database

This blockchain utilitizes the NutsDB as a fast and simple key-value store. /database contains the custom wrappers around various NutsDB methods.

Resources

This project largely follows an excellent tutorial on building a Blockchain in Go. The main differences are project organization and the use of NutsDB instead of BoltDB.
