Hi,

Could you, please, add the practical guide for building a blockchain from scratch in Go

I've developed a blockchain from scratch in Go with gRPC for learning purposes. I've also written the guide that explains the design of the blockchain along with practical usage examples. I hope the guide will help to effectively learn the blockchain concepts and progressively build a blockchain from scratch in Go with gRPC
