Decisions are made based on voting (smart contract)  Application Logic Contracts         - Communication with smart devices through contracts (IOT) Each Contract lives on the Ethereum network and has an unique address with ether balance. If we want execute something on the contract we need to use the contract address to do actions. It has data and code associated with it Similar to OOPS concept. Ethereum nodes don't run the solidity code. First, Transforms the code to bytecode and deploy it in the network. Each nodes has EVM which will executes the bytecode. Languages to write contracts:   Solidity  - Javascript like...

Origin of Ethereum:  At Some point Blockchain technology became very popular. One Blockchain per Application. It's very difficult to create our own blockchain for every new applications. Ethereum concept came here, it's aim to create a single blockchain for that will allow to create any kind of new applications on top of it.   History of Ethereum: 2013 - Ethereum whitepaper by Vitalik buterin   2014 - Ethereum Development 2015 - Olympic Release Eth network was created 2020 - Boom in DeFi Activities 2022 - The Merge Upgrade of Execution layer Overview: Ethereum Projects: AUGUR - Prediction Market OPENSEA - digital collectibles UNISWAP - Assets Exchange COMPOUND - Leading platform Decentralized Application : Ethereum allows us to build new applications called Decentralized Applications . Just as regular applications, they run on multiple machines. But what differs them is that these machines are not owned by single group or organization. They are owned by different people i...
