In today's video we will learn how to Integrate React.js with Smart Contracts (read / write / events)
Smart contracts are computer programs that are hosted and executed on a blockchain network. Each smart contract consists of code specifying predetermined conditions that, when met, trigger outcomes. By running on a decentralized blockchain instead of a centralized server, smart contracts allow multiple parties to come to a shared result in an accurate, timely, and tamper-proof manner.
Learn how to:
- read and display data from smart contracts
- issue or sign new transactions from React.js
- listen to events emitted by ethereum smart contract.
