Andrei completely broke down the barriers to understanding Solidity and Blockchain programming, so many basics that are fundamental to understanding this tech were clearly explained. Very Impressive!" by Peter Olisa"Highly recommended course. Goes directly to the point, explaining many examples of real-life smart contracts. Instead of a lot of JavaScript front-end programming, as in other courses, it goes directly to dApp development. Very useful indeed." by Jose Ferdandez"The course is well structured and really in-depth. The instructor does a really good job explaining the concepts, with examples. I would recommend this course to anyone interested in the subject." by Andrei BuiuThe topics covered in this course are:What is the Ethereum Blockchain PlatformEthereum Accounts, Addresses, Transactions & Blocks, Gas, Opcodes, and MiningTools used for Ethereum DevelopmentEthereum Smart Contract Compilation, ABI, Bytecode, and Deployment to different Ethereum BlockchainsSolidity SyntaxIn-depth details about Solidity State Variables and FunctionsSolidity Fixed-Size Arrays, Dynamic Arrays, Structs, Enums, Mappings, Global Variables, etcContract Address and Balance: Sending Ether to a Contract, Payable & Fallback FunctionsAccessing the Contract BalanceVariables and Functions Visibility: Private, Public, Internal, ExternalEventsContract Inheritance, Abstract Contracts & InterfacesReal-World examples of how to create secure Smart Contracts for a decentralized unstoppable Lottery, Auction or CrowdFunding Platform, ERC20 Token, and ICOWhat is the InterPlanetary File System (IPFS) and how IPFS works?
