KarChain

Sample project to keep car data in a blockchain.

How it works

Any data generated by a car (let's call it X) could be translated to a block. This block has some fields:

• index (position);
• hash (previous block hash + X's name + X's data)
• previousHash (previous block hash)
• timestamp (time it was created)
• name (license plate)
• data (any data, like current speed)

For every new block generated a new blockchain will be created, with his last data (blocks) plus the new block.

Implementation

Current implementation uses Kotlin and is heavily based on functional programming concepts.
