blockcrypto v4.2.0

BlockCrypto

This is a core blockchain package coded in Javascript which contains business logic for managing a blockchain cryptocurrency. This blockchain implementation closely resembles that of Bitcoin. Much thanks to the many online resources and youtube videos which helped in the making of this package.

Installation

npm install blockcrypto

How it works?

• Proof of work blockchain
• Cryptocurrency implementation with mining rewards and mempool (pending transactions)
• Mining algorithm finds SHA256 hash that is lower than the target hash by modifying the nonce value

• secp256k1 elliptic curve function used to generate public key

• utxo used as input and outputs of transactions.

• address generated from public key by SHA256 and RIPEMD160 algorithms with checksum implemented, represented in a base58 format.
