WannaChain

A simple implementation of a block chain network.

Introduction: 5 minutes into blockchain by code.

1. Block Chain

• A list of distributed chain of blocks accross a p2p/distributed network.

2. Block

A single block in the chain that contains:

• Data: that is shared across network.
• MetaData: to verify the block.

3. Contracts

A set of rules those are agreed across the network:

• Data Contract: rules to validate data of a block. (ex: bitcoin block data contains valid bitcoin transaction).
• Block Contract: rules to validate meta data of a block. It's a like a mathematic problem needs to be solve in order to

4. Adding a new block (mining)

Collect valid data that is shared a cross network and create a new block that satifies the block contract.

5. Take a rest.
