Smart Contract in Ethereum Blockchain TABLE OF CONTENTS (HIDE) Writing Smart Contracts in Ethereum Blockchain To program Ethereum blockchain, you need to be familiar with JavaScript and full-stack web development under Node.js. Introduction to Blockchain Technology [Work In Progres] A blockchain is a distributed digital ledger of transactions . It contains records of all transactions or events that have been executed, which are shared across the nodes participating in the blockchain. A blockchain is segregated into blocks. Each block contains encypted data on the transaction, sender/receiver, and the previous block's hash. The block is then appended to the chain in chronological order, hence, the name blockchain. Blockchain is immutable and trusted ... Blockchain is distributed, peer-to-peer, decentralized, not controlled by an single party, no intermediary to verify. Consensus algorithms (to prevent double-spending): Proof of Work (PoW): For each block ge...
