Simple blockchain

Shamefully inspired from this article (code).

Principle

• When connected to peers, it's become an node.
• When generates a new block, node broadcasts it to others connected peers.
• When a node connects to a new peer it querys for the latest block.
• When a node encounters a block that has an index larger than the current known block, it either adds the block the its current chain or querys for the full blockchain.

HTTP methods

• Get all blocks: GET /blocks
• Start mining: POST /mine
• Get all connected peers: GET /peers
• Connect to peers: POST /peers

Get started

Run HTTP and P2P servers:

$ yarn run dev

Tests

Run tests:

$ yarn run test
