Proof-of-Work blockchain using SHA-256 hashing algorithm, created in .NET (C#).

.NET-Blockchain

Introduction

I have created a blockchain (code found in Program.cs) using the .NET infrastructure and C#. In addition to setting up classes for the blockchain and blocks, I have created methods to add blocks, find SHA-256 hashes, and carry out computational work to find a nonce such that there is one zero at the end of the hash (proof-of-work).

You can set up your own chain by:

1. Creating a blockchain object with Chain blockchain = new Chain();
2. Initializing the head node by using blockchain.init_chain(messaage, difficulty);. The difficulty is the amount of zeros you want at the end of each hash which can be set this in the main function of the Program class.
3. And last but not least, adding some blocks using blockchain.add_block(prev_hash, index, message);
