What you'll learn

  • Understand what blockchain is and its key components.
  • Bitcoin's Life cycle, key underlying concepts and challenges
  • Learn what are smart contracts, NFTs, ICO and Atlcoins.
  • Used cases of blockchain in other industries and the problems it can help solve.

Course content

5 sections • 28 lectures • 1h 54m total length

  • Introduction2:21

    Take a non-technical tour of blockchain fundamentals, from blocks and distributed ledgers to bitcoins, altcoins, smart contracts, and their real-world applications in health, retail, insurance, and finance.

  • What is a blockchain6:37

    Explore what a blockchain is through a public welfare program, highlighting how distributed ledgers, blocks, cryptography, and immutability improve transparency and reduce fraud, with public, private, and hybrid models.

  • Distributed ledger4:44

    Explore centralized, decentralized, and distributed ledgers, including blockchain, and see how distributed ledgers enable direct communication, remove central authorities, and boost data ownership and security through distributed nodes.

  • What is a block3:36

    Explain how a block bundles transactions or digital records with a timestamp and hash, links to the previous block, forms a chain that preserves chronology, making data difficult to amend.

  • Cryptography6:13

    Explore cryptographic hashes and hash functions, including sha-256, and learn how fixed-size hash values enable fast, deterministic, one-way verification for blocks and transactions in blockchain networks.

  • Immutability3:29

    Discover how blockchain achieves immutability through cryptography and a distributed ledger, where altering a block forces cascading hash changes and a majority consensus attack becomes costly.

  • Consensus Protocol3:54

    Explain consensus protocols, how nodes agree on the blockchain ledger, and compare proof of work, proof of stake, and proof of authority, including energy use and validation.

  • Security - Public and Private keys and Digital Signature4:26

    Explore symmetric and asymmetric encryption, with public and private keys, and learn how digital signatures authenticate senders, guarantee integrity, and achieve non-repudiation for secure data transfer on blockchain.

  • Public, Private and Hybrid Blockchains3:32

    Explore public, private, and hybrid blockchains, their access, control, and performance, and see how consensus and cryptography secure distributed ledgers with Bitcoin, Ethereum, and IBM Food Trust.

Requirements

  • It is a beginners' course. No prior experience or knowledge required. All that is required is an open mindset and interest to learn about Blockchain, how it works, and its use cases.

Description

For enthusiasts, blockchain is the solution to every problem. For the less-so enthusiasts, it is a solution waiting for a problem to solve. The rest fall in between.

Irrespective of which side you are on, every informed person needs to know about blockchains as Blockchain is where we will potentially see the next biggest opportunities in the coming decades. Together with other emerging technologies, blockchains will help change the way various companies operate and will create new asset classes. It is a disruptive technology but for the ones who are ready to adopt and change, there is an immense opportunity ahead.
