Core Blockchain Concepts, Blockchain Overview (Polkadot Blockchain Academy, Buenos Aires 2023)

Polkadot Blockchain Academy, Buenos Aires 2023 - Module 3: Blockchain - Lesson 1 Blockchain Overview This is the first lesson of the Core Blockchain Concepts module instructed by Joshy Orndorff and Andrew Burger. In this lesson we discuss blockchain's place in society and history and the value of decentralized concensus in a conceptual way. We also discuss state machines to model interactions. --- Context: The second cohort of the Polkadot Blockchain Academy met in Buenos Aires in January 2023. Although the program was young at that time, the atmosphere was of learning and curiosity. While that in-person atmosphere cannot be fully captured in a video, we are now releasing these lecture recordings to give a glimpse into the PBA experience, and allow all the world to learn along with us. If you like what you see, apply to come in person at polkadot.academy/ The content here is rough in some ways. It has matured, evolved, and developed structure in the two cohorts that have elapsed between recording and publishing. But that raw content helps to capture the spirit of these early cohorts where learners and instructors worked together to transfer knowledge as coherently and completely as possible. We invite you to learn with us now. polkadot.academy/ --- Timestamps: 00:20 The core problem 04:19 Web0, Web1, Web2 10:07 Digital services 17:02 Web3 - No need to trust the service provider 23:33 A shared history 26:05 State machines 36:11 Shared stories about state machines 36:47 Blockchains 41:33 Blockspace 44:03 Learn more Links from the "Learn more" slide: a16zcrypto.com/blockspace-explained/ www.rob.tech/blog/polkadot-blockspace-over-blockch…    • 90 - 5 Mental Models for Web3 | Chris...   --- Apply to the PBA at polkadot.academy/ ✍️ Learn www.polkadotacademy.com/ 🐦 Tweet twitter.com/@AcademyPolkadot 👔 Visit www.linkedin.com/school/polkadot-blockchain-academ… The Polkadot Blockchain Academy is the first of its kind — a classroom-based educational program covering the conceptual underpinnings and the hands-on application of blockchain technology, using Polkadot and Substrate as the foundations.
