The Complete Course on Blockchain and Bitcoin

Learn the technical fundamentals of blockchain technology, including hash function, block linking, consensus mechanisms (proof of work, proof of stake), public and private keys, and forks.

Discover how blockchains grow through linked blocks secured by cryptography, solve the double spend problem with a tamper-proof, transparent, and trustless ledger, and enable decentralized, secure cryptocurrency use cases.

Learn how blockchains use sha-256 hash functions and mining to secure blocks, link them with the previous hash, and resist tampering in a stylized bitcoin-like example.

Compare centralized and decentralized systems, and explore distributed consensus in blockchains, including proof of work, proof of stake, and proof of importance, noting that no single mechanism is considered best.

Understand the proof of work consensus where miners solve a hash puzzle with a nonce to form the next Bitcoin block from the mempool, earning rewards and fees.

Explore proof of stake as an energy-efficient alternative to proof of work, using stake and a lottery to select the next block, with centralization and nothing-at-stake caveats.

Sign transactions with a private key and verify with its public key to prevent unauthorized spending from public addresses on the blockchain, using a hash-derived public address.

Learn how blockchain forks arise when a protocol update breaks backward compatibility, creating hard forks like Bitcoin and Bitcoin Cash, and how miners and users decide which chain to support.

Explore the history of bitcoin, the first blockchain application, and compare bitcoin with bitcoin cash while surveying the top 10 cryptocurrencies and their valuation factors.

Trace the history of Bitcoin from the 2008 white paper and genesis block to pivotal events like Mt. Gox and the Satoshi Nakamoto mystery, including price milestones and forks.

Explore the 2017 Bitcoin Cash fork at block 478,588, contrasting on-chain scaling with eight megabyte blocks against SegWit and off-chain scaling via second-layer transactions, and their impact on transaction costs.

Explore altcoins beyond bitcoin, comparing key cryptocurrencies like litecoin, ripple, dogecoin, monero, dash, tether, and bitcoin cash, highlighting market growth, privacy, stability, and use cases.

Explore how utility value and speculative value drive cryptocurrency prices, highlighting use as a medium of exchange, store of value, merchant acceptance, transaction costs, and bubbles like tulips.

Explore blockchain use cases through the Atomic framework, covering assets, trust ownership, money, identity, and contract topics.

Explore blockchain use cases through the atomic framework—assets, trust, ownership, money, identity, and contracts—and see how secure, trustless applications empower business, industry, and individuals.

Explore asset use cases on blockchain, including colored coins that record ownership and enable transfer without intermediaries, and protect digital collectibles and in-game items stored on the blockchain.

Explore trustless blockchain use cases across marketplaces, data storage, and social media; show how decentralized rules, and disintermediation enable peer-to-peer exchanges and new platforms like Steemit, OpenBazaar, and Slock.it.

Store ownership and authorship proofs on a blockchain to establish irrefutable, timestamped rights for digital or physical assets. Track provenance across asset histories, enabling verifiable ownership and legal rights.

Explore how blockchains enable money use cases with fast peer-to-peer payments, store of value potential with fixed supply to guard against inflation, and privacy variations across Bitcoin, Litecoin, and Monero.

Explore how blockchain enables tamper-proof identity records and offline-online identity integration, enabling blockchain-based voting, reputation management, and single sign-on.

Explore how blockchain enforces contracts with smart contracts and oracles, enabling peer-to-peer lending, flight-delay insurance, and ride-sharing through distributed autonomous organizations and supply chain use cases.

Gain a practical, hands-on guide to buying, trading, and securely storing digital assets, and explore the ecosystem behind them, including hardware wallets as the safest storage option.

Open a gateway exchange to convert fiat into digital assets and start trading. Store assets in cold storage, then diversify on crypto-only exchanges and withdraw back to fiat if needed.

Store your digital assets safely by using cold storage, preferably a hardware wallet; keep private keys offline to prevent hacks and avoid hot storage.

Explore how hardware wallets store private keys on-device, require physical button confirmations, and use seed recovery to protect funds on Ledger, Trezor, and KeepKey.

Explore the blockchain scalability outlook, examining rising transaction fees and on-chain and off-chain solutions like Bitcoin cash, SegWit, Lightning network, sharding, plasma, Raiden, and Casper.

Deepen your understanding of blockchain technology and how it works, then engage with the blockchain community and share a review to help future students learn from this course.
