C# blockchain implementation

Blockchain

An extensible and flexible C# blockchain implementation, the main purpose of which is to demonstrate basic blockchain concepts.

Key solution elements / concepts

Node

The core element is the node, responsible for the basic blockchain functionality (e.g. add, retrieve, validate etc.)

Chain store

Every node needs to use a storage provider to store the blockchain, there are currently two chain store implementations, InMemory (default) and Redis.

InMemory

Blockchain is stored in application memory. This is the default and easiest option to use although doesn't provide any persistance between application restarts (although a function of a node is to "persist" a chain to file as a method of backup that can be easily restored on application restart). A node connector can also be used to replicate your blockchain between applications should one of your node quit unexpectedly.

Redis

Blockchain is stored to a specified redis instance, a high performance in memory data store. see https://redis.io/ .

Node host

Using a node host is optional, you can always use a node directly in your own codebase. A node host acts as a wrapper for your node exposing its blockchain functionality in different way.

HTTP

The "http" node host exposes an HTTP API with basic "GET", "ADD" and "COUNT" functions.

Node connector

A node connector connects two or more nodes for purpose of replication to aid scalability, resiliency and redundancy. There are currently no completed connectors.

Future developments

Additional chain stores:

• MongoDb

Additional connectors:

• P2Pconnector
• Mirror

Other:

• Dockerised blockchain node with HTTP node host
• Improved documentation
• Nuget package
