This small app provides a basic blockchain simulation.
The blockchain starts with the genesis block and can be continued by adding more blocks. Each block points to the block before through the previous block's hash. The newly created hash is the fingerprint of the summoned data, index, previous hash, timestamp and nonce. The mined nonce makes sure that the hash begins with four zeros and makes the block therefore "signed".
Manipulating any data within any block of the blockchain (which can not be simulated (yet) in this demo) breaks the chain and results in invalid bloc
