Blockchain promises to disrupt industries once it will be efficient at large scale. In this course, you will learn how to make blockchain scale. You will learn about the foundational problem of distributed computing, consensus, that is key to create blocks securely. By illustrating limitations of mainstream blockchains, this course will indicate how to improve the technology in terms of security and efficiency.

This week, we will start our exploration of the blockchain and its relation to distributed computing. In particular, we will learn the basics on blockchain abstraction and the importance of consensus between machines in order to mitigate the risks of having an attacker spend the same asset twice - an undesirable situation called 'double-spending'.

This week we will learn how classic blockchains try to solve consensus. We will look at the failures and delays blockchain systems must consider, and how these events may prevent machines from reaching consensus.

This week, we will investigate how to solve the consensus problem. To do this, we will first investigate how to solve consensus when failures cannot occur in the network. Later on, we will learn how to solve consensus when processes may fail, first through crash failures and then when processes can behave arbitrarily.

This week, we will investigate how delays in the network can impact the security of the blockchain. We will illustrate this using network attacks that allow hackers to steal digital assets in the past and that every blockchain designer should be aware of.

This week, we will explore how to design a scalable and secure blockchain algorithm. What makes a blockchain algorithm scalable and secure? To be secure, we need a consensus algorithm that works over the Internet and is not affected by unexpected communication delays. To be scalable, we need to get rid of the bottlenecks.

Häufig gestellte Fragen
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
