A quick example of setting up a basic P2P blockchain in dotnet core. This is purely a basic example and is by no means complete. Potential issues/improvements will be listed below
To run this project you will need the dotnet core 2.1 SDK installed. If you haven't use this SDK before, see here for instructions on how to get started.
You will also need an instance of Consul for P2P to work. I personally use Docker to run this.
- Build the application to a DLL using
dotnet publishin the root directory. - Optionally start your Docker Consul instance with
docker run -d -p 8300:8300 -p 8301:8301 -p 8302:8302 -p 8500:8500 -p 8600:8600 --name=dev-consul -e CONSUL_BIND_INTERFACE=eth0 consul - Start as many instances of the application as you like by running
dotnet BlockchainExample.Server.dll -o Node:Port={YourPortNumber}in the publish output directory (using seperate console windows)
You must run 3 instances of the app. The ports/instances are hardcoded and they all need to be there when you mine a new block as it will try to update the entire network- Added service discovery- If you close the app too quickly after stopping the server, it will sometimes give you an "ObjectAlreadyDisposed" Exception
Add service discovery so that new nodes can be detected as they are added. This would remove the need for hardcoded nodes- Done- Non-local IP addresses. Currently it's hardcoded to 127.0.0.1 but it would be nice to be able to access it externally so that each instance could be run in a container or on another machine
- General code clean up
- Tests (I didn't put any in since it was just a quick example but if I expand it any further I will put tests in)
- Currently blocks are created without any data which makes them a bit pointless. This needs to be expanded so that they contain transaction data
