Blockchain in TypeScript

Information

Do not try to use this as a real cryptocurrency. It is a naive, bare-bones implementation of a blockchain with a cryptocurrency stored in the blocks and it is in no way guaranteed to be secure.

It was created for a presentation at Youngstown State University's Local Hack Day 2019. Slides are in the /docs folder.

All the fundamental technologies are present, including a blockchain with hash pointers, peer-to-peer networking, and a consensus mechanism.

Building

Look in package.json for the scripts.

• yarn run build - check the types and code style, run unit tests, and compile TypeScript (from /src) to JavaScript (in /lib)
• yarn run build-docker-image - builds the Docker image using the Dockerfile configuration

Run three miners by building the docker image and then running docker-compose up

Use Postman or curl to send transactions or check wallet balance, block chain state, or mempool state.
