Understand the main components of distributed ledgers and blockchains

With the rise of the digital economy, it’s no surprise that cryptocurrencies and blockchains are growing in popularity.

This three-week course from King’s College London and Quant Network will empower you with an understanding of how blockchains and distributed ledgers work as well as their advantages over centralised ledgers.

Once you’ve completed this course, you will have the foundational knowledge that you need to become a blockchain developer.

Be introduced to cryptocurrencies

There are thousands of cryptocurrencies in existence. On this course, you will learn how to develop programs to send and receive payments for BTC, ETH, and XRP.

Importantly, you will also learn about the groundbreaking distributed ledger technology that these cryptocurrencies are built on.

Learn how to build programs that interact with distributed ledger technology

Applications built on distributed ledger technologies (DLTs) are more transparent, promote decentralised control, and are more resilient to software crashes as well as malicious actors.

On this course, you’ll gain the skills needed to create your own applications and programs that can interact with and be built on DLTs.

Study with the specialists at King’s College London and Quant Network

The King’s College Department of Informatics has a long-established leadership in the Distributed Artificial Intelligence domain, which is closely related to blockchain.

Coupled with the DLT know-how of Quant Network, these experts are the perfect guides to help you become a blockchain developer.


  • Week 1

    Introduction to Distributed Ledger Technologies

    • Ledgers

      We first must gain an understanding on what centralised and distributed ledgers are. Only after which can we understand what distributed ledger technologies can offer.

    • Distributed Ledger Technologies

      Now that we have introduced ledgers, centralised ledgers and distributed ledgers, we can start to dive deeper into the different components of distributed ledger technologies.

    • Week Wrap Up

      We complete this week with a discussion and quiz.

  • Week 2

    Distributed Ledger Technology Data Structures

    • Introduction

      A brief introduction on why asset tracking models are important in distributed ledger technologies

    • The Unspent Transaction Output Model

      In this section, you will learn how the Unspent Transaction Output (UTXO) model affects how transactions are formatted, how the current state is structured and how smart contracts are written

    • The Accounts Model

      In this section, you will learn how the Accounts model affects how transactions are formatted, how the current state is structured and how smart contracts are written

    • Week Wrap Up

      We complete this week with a discussion and quiz.

  • Week 3

    Cryptography in Distributed Ledger Technologies

    • Introduction

      In this section, you will be introduced at a high level to the relevant cryptography background.

    • Cryptography in Distributed Ledger Technologies

      In this section, you will be learn about the cryptography that is used in distributed ledger technologies and why it is used.

    • Course Wrap Up

      We complete this week and this course with a summary, discussion and quiz.
