Extending Rchain

Rust is quickly becoming one of the most popular languages in the blockchain industry. It is also equally important to understand how different components of a blockchain work. So to knock two birds with one stone your group will be extending Rchain.

Getting started

1. Understand and familiarize with the Rchain codebase
   • Learning Rust [1][2]
2. Run Rchain as per example
   • Multiple users on the network
   • Both example attacks

Objectives

Now that you have the basic Rchain running, its time to extend it! As a team you will work together on 1 github repo to extend Rchain. The repo should contain a README with set up instructions and the code should be commented. This is due 1 week from now

1. Extend World State with get_total_tokens() to display the current token total in the network.
2. Extend World State with get_transactions_for() display all the transactions in coronological order and block # for a given id.
   • Tip: 1 & 2can be calculated by walking through the chain
3. Add signed message functionality
4. Scale to 10 users on the network.
5. Build a presentation that covers the fundamentals of your groups chain and a series of screenshots that provides 1-3 functionality.
