Introduction to Blockchain

Intro to Blockchain reintroduces students to technology through the lens of trust, agreement, and decentralization. The course opens by asking a deceptively simple question: why is it hard for strangers to agree on the truth? From there, students learn how blockchain answers that question by combining cryptographic linking, distributed storage, consensus mechanisms, and immutability into a system that is tamper-resistant by design.

The first half of the course focuses on the technology itself and its relationship to cryptocurrency. Students explore how hashing turns information into a digital fingerprint, how blocks link into a tamper-evident chain, and how consensus mechanisms allow strangers to agree without a central referee. They then examine how cryptocurrency is built on top of blockchain, how to buy and sell crypto responsibly, and how to store digital assets securely using the right kind of wallet.

The middle of the course broadens the picture. Students compare major networks including Bitcoin and Ethereum, survey the wider ecosystem of altcoins and tokens, and learn how to read market data without losing perspective. Security becomes a central theme as students study the anatomy of common scams and develop practical habits for protecting their digital assets.

The second half of the course ventures into the frontier of what blockchain makes possible. Students explore decentralized finance, non-fungible tokens, and the decentralized web, examining both the promise and the hype surrounding each. The course concludes by asking students to synthesize everything they have learned into a coherent personal framework: evaluating whether blockchain is the right tool for a given problem, and building a crypto strategy that actually makes sense for their own goals and risk tolerance.
