I need a C# implementation of the Ripple Consensus Algorithm as described below.  In other words I only need a way to build consensus among peers as described in this video:

Consensus Video: https://www.youtube.com/watch?v=pj1QVb1vlC0

What are they making consensus on? For my use case, it's not "ripples", instead, all nodes have to agree that random number X in the range of 1 - 10,000 equals random number Y.

NO Cryptography is needed in this project.  
NO Networking code is needed in this project.  

Instead of networking, the code will spawn a new thread that simulates each node class.
- There will be 100 classes of type node in memory (configurable).  
- As each node starts, the constructor will use a lock to add a reference to itself in the static dictionary
- A random wait time from 1-30 seconds will occur
- Each "node" will locate 5 random other nodes from a C# static dictionary.

At this point we have 100 nodes in RAM that create a mesh network.

The Main program will have a console prompt that asks me to type in a node number (in this case I type in a number from 1 to 100).  
The Main program grabs an object reference from the static dictionary.

Next the console application will ask me what variable "X" is.  I input an integer.  
Next the console application will ask me what variable "Y" is.  I input an integer.  

It's up to you to implement the consensus algorithm in a way the ensures all in-memory nodes get updated.

Part two of this project is to randomly poison the in memory nodes so that they
- Don't replicate the value (ignores it)
- Replicate a wrong value
- Delay the response in a FIFO queue

It's for several things

- Classroom simulation and learning
- An experimental general ledger I'm experimenting with

I don't envision it being too hard, but I haven't read the original source.

Because this code will be reviewed by PhDs and such, I need it to feel like a professional wrote this code (Unit tests, etc)

It seems straight forward enough. C# has lots of TCP/UDP (https://gist.github.com/leandrosilva/656054) and websocket libraries (I've used some myself (https://github.com/statianzo/Fleck)). I think you should be able to get it done within 2 days (with the share amount of opensource libraries around). Give it a try.

You're right, I could do it myself, but I have a deadline and need to push other code first. This can be delegated. 

LMK if you know anyone
