BlockChain

The goal of this project is to build a basic blockchain with a proof-of-work mechanism and Merkle tree-based data storage.
Score : 10/10

Deliverables

1) Code :

A)implements a blockchain—in particular, a main loop that repeatedly obtains new data and computes and outputs the hash ​H(d)​ of data structure ​d​ .

B) The data structure ​d​ must contain

• a hash of the previous block
• a Merkle Tree (see instruction D below)

• a nonce

  C) The first 16 (binary) digits of each block hash must be 0.

  D) the Merkle Tree must be build from all valid elements received from the DataSimulator, i.e. all valid ​(publicKey, message, signature)​ tuples where the signature is valid

2) Provide a Merkle Tree-proof that a specific item is part of the Merkle Tree in an ancestor of the last block.

In detail, given the created blockchain after 5 blocks, show proof that the headline
