This document discusses Ethereum, smart contracts, and blockchain technology. It defines Ethereum as a cryptocurrency platform that allows for decentralized services and applications through the use of smart contracts written in the Solidity programming language. Smart contracts are computer programs that automatically execute transactions, actions, and legally relevant events without the need for intermediaries. The document provides examples of how smart contracts could be used for elections, digital currency, and instant money transfers with low fees. It also discusses tools like Ganache, Truffle, and Web3.js that allow for developing, testing, and interacting with smart contracts and decentralized applications.

- 10. It’s a type of digital currency, the accounting of internal accounting units of which is provided by a decentralized payment system, operating in a fully automatic mode. What is cryptocurrency?
- 11. Cryptocurrency and platform that provides a possibility to build decentralized services based on blockchain that works on Smart Contracts: What is Ethereum? - 2 largest capitalization in crypto-world ($379,359,819,599) - Smart contracts use Solidity (Looks like Typescript) - Actively developing - Open source
- 12. A smart contract is a computer program that is intended to automatically execute, control, or document legally relevant events and actions - Automatically execute - No need for any proxies - Safe and confidential - No need any paper What is Smart Contracts
- 13. End of theory

- 21. What we should solve? - Time - Automation - Transparency Issues
- 26. How does it work from a technical perspective?
- 27. Let’s start with Web3.js
- 28. It makes it possible to connect to an existing network or create a new one, view the event log in the blockchain, transactions, etc. - $npm install ganache --global - $ganache-cli <args> Or use GUI, works really perfect! Ganache CLI
- 29. Truffle is the most popular development framework for Ethereum with a mission to make your life a whole lot easier. - Built-in smart contract compilation, linking, deployment and binary management. - Automated contract testing with Mocha and Chai. - Provider for Web3 - ... Truffle
- 30. DApp interaction with contract
- 31. Smart Contract via Solidity
- 32. Workflow API Web3.js SC(viaTruffle) Blockchain (via Ganache) Client from Egypt Checkpoint
- 34. - Elections (easy to integrate to DIIA) - Replacement of the national currency with e-currency (Ukraine is one of the first who started work on e-hryvnia) - Transfer of any amount of money with a minimum commission instantly (this is what paypal does) Where we can use smart contracts?
