Mastering Solidity: Developing Decentralized Applications

Explore decentralized application development with the Solidity programming language, bridging blockchain knowledge, and learning smart contracts, tokens, and deployment across private chains and the Mist browser.

Bridge the knowledge gap in decentralized application development by learning blockchain basics, Ethereum concepts, and smart contracts written in solidity from scratch.

Explore how decentralized applications rely on blockchain and distributed networks, featuring open governance, consensus protocols, and token-based value to ensure fault tolerance and censorship resistance.

Trace the origin of decentralized applications from centralized transaction patterns to tamper-resistant blockchain foundations powering Bitcoin and Ethereum, and learn about shared ledgers, consensus, smart contracts, and key roles.

Explore Mist browser as a client-side Ethereum wallet and full node that manages keys and accounts, enabling on-chain transactions, contract deployment, and interaction with the Ethereum virtual machine.

Explore the Ethereum virtual machine, a global 256-bit computer that executes transactions and smart contracts for ether, enabling state changes across blocks, including the genesis block and canonical block.

Learn Solidity, the contract-oriented language for building smart contracts on the Ethereum Virtual Machine, powering decentralized applications. Explore Remix and Visual Studio Code, compiler basics, and simple contract structures.

Explore solidity's value and reference types, including booleans, integers, addresses, arrays, mappings, and fixed point numbers, and learn data locations like storage, memory, and call data for smart contracts.

Explore Ethereum nodes and go-ethereum geth to connect to the Ethereum network, mine blocks, deploy smart contracts, and set up a private genesis block blockchain.

Set up a private chain network to develop and deploy a demo smart contract on a private blockchain, initializing the genesis block and configuring the chain data with go Ethereum.

Learn to create your first smart contract with solidity on the ethereum network using truffle, including a hello contract with a getmessage function.

Develop a revenue sharing contract in Solidity, declaring address shareholders array and implementing a share revenue function that distributes ethers to shareholders, with a disperse event and self-destruct kill function.

Learn to use Remix to compile Solidity contracts, read warnings and errors, and refine a revenue sharing model by addressing constructor deprecation, visibility, and event invocation.

Run smart contracts in remix ide using the javascript vm environment, adjust gas limits, accounts, and ether, and observe contract creation and mined transactions, including revenue sharing functions.

Understand the structure of smart contracts in Solidity, including contract declarations, state variables, events, modifiers, constructors, and data locations in memory and storage, guided by versioned pragma Solidity rules.

Explore different types of contracts and learn to build a simple storage contract in Solidity, including storage variables, set and get functions, and returning stored values.

build a solidity coin contract named coin with address to uint mappings, balances, and events; implement mint and send with access checks, and debug in remix.

Implement a simple auction contract in Solidity with a public beneficiary, bidding time, and highest bid tracking. Trigger bid and auction ended events, and finalize payments when the auction ends.

Create a blind auction contract in Solidity, declaring pragma solidity 0.4.17 and a BlindAuction with blinded bids, beneficiary, bidding end, reveal end, and an auction ended flag.

Develop and test a solidity blind auction contract that handles deposit value, place bid logic, highest bid and bidder updates, and auction end events via Remix IDE.

Discover how mining on Ethereum establishes consensus by ordering transactions, rewarding ether for blocks and uncles, and powering the network through blockchain validation and dapps.

Explore crypto economics as a defense of public networks using game theory, encryption, and hashing to secure the global transaction state machine and deter attackers.

Explore what cryptocurrency is, how blockchain and mining secure transactions, and how Bitcoin, Ethereum, and Litecoin function as digital currencies, plus wallet use, buying, holding, and key security risks.

Explore use cases for decentralized applications on Ethereum, from internet of things and device-to-device payments to retail, crowdfunding, insurance, and cloud hosting via smart contracts.

Explore advanced concepts for decentralized applications, from Ethereum's evolving proof-of-stake roadmap and scalability challenges to Whisper messaging and Swarm content addressing.
