01:10:00 A blockchain is a digital ledger of all Bitcoin transactions. It is decentralized and immutable, meaning that it can never be changed. This makes it a powerful tool for recording and tracking transactions.
01:15:00 Blockchains are a type of digital ledger that allows for secure, decentralized transactions between peers. Each node in a blockchain has the same power as any other node, so it is easy to tell which blockchain is correct. When something happens on a blockchain that a node doesn't like, the node can go back and/or change their blockchain to match the majority consensus.

05:50:00 The video discusses how blockchain technology can be used to create a voting mechanism for proposals, as well as the trade-offs associated with this approach. It also covers the architecture and tools needed to build a voting mechanism.
05:55:00 This video explains the three methods of voting used in blockchain protocols: skin in the game, proof of participation, and proof of personhood. The hardest part about implementing voting in a community is deciding what constitutes a bad outcome. The third method, proof of personhood, is the most interesting and difficult to implement, but may be the most important.

First, the instructor writes a smart contract in Hardhead, then writes deployment scripts in TypeScript. Next, they write scripts to interact with governance of deployed contracts. Finally, they show sick Hardhead skills by writing a governance token in Solidity and extending an ERC20 token with governance features.
06:10:00 This tutorial teaches how to create a blockchain-based ERC20 token and create a governance contract to manage it.
06:15:00 The video explains how a blockchain-based governance system works and how the various contracts involved work together. The video also provides an overview of how to create a proposal and vote on it.
06:20:00 This course provides a step-by-step guide to learning blockchain development, including Solidity and JavaScript. The course covers topics such as governance and voting, as well as deploying and interacting with a blockchain.

06:30:00 The course teaches how to develop a full stack web3 development with JavaScript using Solidity and Blockchain. The course starts by explaining how to install and use the necessary tools and then proceeds to teach how to deploy and run scripts using the command line.
06:35:00 This video teaches how to deploy a contract using the Ethereum blockchain and Solidity programming language. The contract includes a delegate function that allows users to vote on the contract's operations. The video also shows how to verify a contract's deployed state using Etherscan and GitHub.
06:40:00 This course covers the basics of blockchain development, including Solidity, JavaScript, and deploying contracts. The first part of the course covers deploying a governance token, and the second part covers deploying a time lock contract.
06:45:00 This video explains how to develop a blockchain-based application using Solidity and JavaScript. It covers topics such as governance tokens, voting, and quorum. The video also covers how to set up contracts and roles.
06:50:00 The video demonstrates how to create and deploy a box contract using the Ethereum Solidity programming language. First, the video explains how to create and constrain three roles: proposer, proposer role, and executor. Next, the video demonstrates how to grant and revoke roles to users. Finally, the video shows how to deploy a box contract.
06:55:00 This YouTube video tutorial teaches how to develop blockchain applications using Solidity and JavaScript. The course starts by teaching how to create a box contract that stores a specific value, and then moves on to proposing and voting on changes to the box contract. Next, the course covers how to interact with the proposed contract using JavaScript.
This video discusses blockchain, Solidity, and full stack web3 development with JavaScript. It covers how to read and parse JSON, use FS to read files, and sync proposals between nodes. You also learn how to create a vote script and vote on proposals.
07:00:00 This video teaches how to develop a full stack web3 application with JavaScript using the Box and Solidity libraries. The first part of the video covers encoding and decoding data, and the second part shows how to create a proposal transaction.
07:05:00 This video discusses blockchain, Solidity, and full stack web3 development with JavaScript. The instructor explains how to speed up blockchain processing using a local blockchain.
07:10:00 This 32-hour course teaches you how to develop blockchain and full stack web3 development with JavaScript. You learn how to read and parse JSON, use FS to read files, and sync proposals between nodes. You also learn how to create a vote script and vote on proposals.
07:15:00 This video explains how to use blockchain and Solidity to develop a full stack web 3.js application. The video covers importing various libraries and then voting on a proposal.
07:20:00 This course covers blockchain development, including Solidity and JavaScript, with a focus on full stack web3 development. The course starts by introducing the concepts of blockchain and smart contracts, and goes on to show how to create a simple proposal and queue execution using the Governor contract. Finally, the course covers how to hash the description of the proposal to check for completeness, and how to move time to speed up the voting process.
07:25:00 This video teaches how to develop blockchain applications with Solidity and JavaScript. It covers how to move time and blocks, queue moves, and conduct audits.
07:30:00 In auditing a blockchain project, an auditor will first run the project's tests to ensure that the code is working as intended. Next, the auditor will read the project's specs to determine what functions are implemented and how they are designed. Finally, the auditor will run some fast analysis tools to look for common bugs.
07:35:00 The video explains how to use Slither, a Python-based tool for security analysis of contracts, to identify issues with the code of a metamorphic proxy and a vault. Slither finds that the metamorphic proxy is never initialized, and the vault contains a password that could be accessed by anyone.
07:40:00 This course covers the basics of blockchain development, including Solidity programming and static analysis with Slither. After installing Docker, the course demonstrates how to write fuzz tests for Solidity contracts.
07:45:00 This video explains how to use the Kidnapper and Fuzz tester to audit smart contracts. The two most common tasks are reentrant and Oracle manipulation, and if you're not going to be an auditor, you should at least run Slither. After you run through the whole process, you should discuss findings with a smart contract developer and auditor.
07:50:00 This course covers the basics of blockchain, solidity, and web three development with JavaScript. There are resources for security awareness and for catching vulnerabilities.
