NBlockchain

NBlockchain is a .NET standard library for building blockchain applications.

This project is currently in alpha status and any contributions are welcome.

The idea is that the developer would only need to focus on the data and rules for a blockchain and not worry about having to build all the infrastructure to facilitate a blockchain.

The developer would need to

• Define the schema of data / transactions they would like to store on the blockchain
• Define the rules for a valid transaction
• Select or create an appropriate local database
• Select or create an appropriate network implementation
• Select or create one or more peer discovery implementations

Beyond this, it is meant to be highly customizable, you can switch out the default services for

• Address encoding
• Signing
• Hashing algorithm
• Block verification
• Block consensus method (eg. proof of work, etc...)

Installation

Using Nuget package console

PM> Install-Package NBlockchain -Version 0.5.0-alpha

Using .NET CLI

dotnet add package NBlockchain --version 0.5.0-alpha

Samples

• Digital Currency

Local database stores

• LiteDB (Default built-in)
• MongoDB

Networking implementations

• In memory (mostly for testing & demo purposes)
• Tcp sockets

Peer discovery implementations

• Static (from a config file, etc...)
• Multicast (for finding peers on the local network)
• More to come....

Key features

• Automatic chain fork detection and resolution
• Open, flexible transaction schema
• Customizable transaction level rules
• Customizable block level rules
• Peer discovery
• Proof of work management
