A Blockchain example in Typescript

A Blockchain Example in Typescript

This is a basic example of how the blockchain works. It uses a crypto currency (simpleCoin) as a use case to demonstrate:

1. A Transaction
2. A Block
3. How Blocks are chained
   • Proof of Work
   • Mining Transactions and Rewards

Limitations:

As already stated this is just a basic example. A fully working and operational blockchain would require much more functionality such as:

1. A P2P Network with Transaction Verification
2. Blockchain Data Storage to Disk
3. Public / Private Keys to secure transactions
4. A Wallet

To run this you require the following:

1. npm
2. Typescript
3. gulp

Please see this Typescript Quick Start Guide for some instructions.

Compiling and running

At a terminal prompt browse to your source directory

$ cd blockchain

Compile and build the js file using gulp

$ gulp

This will create a new file in the dist/ folder called blockchain.js.

Run this using node

$ node dist/blockchain.js

This will run the code found in test.ts.
