The user interface of your program should look something like this:

Choose an option:

Add a new block to the chain

View the chain

Check chain validity

Search for a block

Mine new block

Enter your choice:

Specific Requirements:

R1: Create a function for generating hashes

R2: Create a Block data structure

R3: Create a Blockchain data structure

R4. Create a program that adds blocks to your blockchain

R5: Print out the blockchain (view the chain)

R6: Create an algorithm that tests the validity of the blockchain

R7: Create a function that searches the blockchain for a particular hash

R8: Implement a function to “mine” a new block

R1: Create a “Block”

Assumptions:

All blocks hold string data

The string data is maximum 50 characters long.

A block is composed of the following properties:

Data you want to put in the block

Hash of the current block

The parameters for hashing is:

Current block data

Previous hash

Current date and time

R2: Create a hash for the block

Create the algorithm for generating a hash for the current block.

The formula for hashing a block is:

String dataToHash = (hash of previous block) + (current time) + (data in the current block)

R3: Create a Block data structure

The block has the following properties:

Properties

Description

Data in the block

String data

Maximum 25 characters in the string

Current time

Timestamp when the block was created

Previous hash

Hash of the previous block

The genesis block has hash = 0

R3: Create a Blockchain data structure

Create a blockchain data structure.

Implement the chain with the data structure of your choice (array, linked list, doubly linked list, stack, queue, etc)

R4. Create a program that adds blocks to your blockchain

Write a program that adds blocks to the blockchain.

Your program should:

Ask user what data they want to store (string data, maximum 20 characters)

Create a new block to store the user data

Add the block to the blockchain

R5. Print out the blockchain

Add an option to your program so the user can print out the entire blockchain.

The visual output should be something like this:

(Note: these are fake hashes)

Block 1: 192333101

Data = “Jenelle”

Previous Hash: 0

Block 2: 144000332

Data = “Peter”

Previous hash = 192333101

Block 3: 993811091

Data = “Roy”

Previous hash = 144000332

etc

etc

R6: Create an algorithm that tests the validity of the blockchain

Given a blockchain data structure, write a function to verify that every block in the chain is valid.

If the entire chain is valid, output: “Chain is valid” to the screen

Else, output the block(s) that are invalid + the reason why.

R8: Write a program to mine blocks

Program that can mine new blocks. → You do not need to add data to your new blokc. Just use (previous hash + x) ---> and solve for x

Note - this mining process might take a long time (and it may never complete, but that’s okay!)
