Simple Blockchain

Implementation of a basic blockchain.

Block Header

• Previous Hash: Hash of the previous block (Empty for genesis block)
• Current Hash: Hash of self.
• Merkle Root: (TODO)
• Transactions (TODO)
• Nonce: A number used to generate the block's final hash.
• Timestamp: The unix timestamp of when the block is created.

Mining

Similar to BTC, this blockchain is also designed to use SHA265 algorithm.
mineBlock function will continue generating hashes until a valid hash is found.

Chain is initialized with difficult set to 5 (as 1 is too fast on modern computers). For debugging purposes you can set the starting difficulty here.

Initialise with Docker

Setup docker image

docker build . -t simple-miner

Start Mining

docker run -it simple-miner

Initialise on Host

Installation

sudo apt install g++ libcrypto++-dev libcrypto++-doc libcrypto++-utils

git clone https://github.com/marmikshah/blockchain.git
cd blockchain/
make -j

Start Mining

./main.o

P2P Network for multi-node mining.
