Learning objectives
  • Summarize different fundamental concepts, techniques and methods of blockchain
  • Explore different platforms (such as Ethereum) to implement applications on blockchain based technologies such as smart contracts
  • Outline the applicability of blockchain technology for different domains and use cases for Finance and other domains
  • Characterize the linkages between distributed consensus, incentives, mining schemes and various kinds attacks on blockchain based applications
  • Demonstrate an understanding of the underlying technology of transactions, blocks, proof-of-work, and distributed consensus mechanism
  • Identify the key challenges and design goals for building decentralised blockchain based applications
  • Critically assess the usage of blockchain technology for building applications other than cryptocurrencies
Course prerequisites
The course has no prerequisites. But the course requires an interest in and commitment to learn and acquire necessary skills to understand the concepts of Blockchain and Distributed Ledger Technologies, to practice hands-on exercises. However, no prior coding experience or knowledge about Blockchain is required.
Prerequisites for registering for the exam (activities during the teaching period)
Number of compulsory activities which must be approved (see s. 13 of the Programme Regulations): 2
Compulsory home assignments
There will be 3 multiple choice quizzes that will be conducted at diffident stages of the course to test to student understanding of core concepts of the course. In order to qualify for the final exam, the students have to participate in the quizzes and pass 2 quizzes out of 3.

There will not be any extra attempts provided to the students before the ordinary exam. If a student cannot participate in the activities due to documented illness, or if a student does not get the activity approved in spite of making a real attempt, then the student cannot participate the ordinary exam.
Before the re exam the student will be given one extra attempt: one home assignment (10 pages) to make up for two mandatory activities.

Course content, structure and pedagogical approach

Blockchain is the decentralized distributed database technology that is combined with guarantees against tamper-resistance of transactions/records using cryptographic methods. By using time-stamping of its transactions and messages, blockchain provides universally verifiable proofs for existence or absence of a transaction in the distributed database and the underlying cryptographic primitives using hash functions and digital signatures provide a guarantee that these proofs are computationally secure and verifiable at any point of time. Blockchain is decentralized, jointly maintained by a plurality of independent parties/nodes and achieves a consistency of transactions among distributed nodes by using distributed consensus protocols (such as Byzantine fault tolerance algorithm) without the need of having a central authority. Blockchains Transactions are transparent and visible to all users of the system and at the same time blockchain provides aspects of privacy and anonymity to its users by allowing them to create pseudo-anonymous transactions without the need for disclosing their personal information.

 

The disruptive and innovative nature of blockchain technology laid the foundation for the evolution of many decentralized applications such as cryptocurrencies and smart contracts. Bitcoin, a decentralised cryptocurrency based on blockchain technology was introduced in 2009 and as of now, Bitcoin is the largest cryptocurrency with a market capital of approximately more than 100 billion USD.


The aim of this course is to provide knowledge about various concepts, techniques and methods that are serving as the technical foundations to blockchain technology and a thorough understanding of how decentralised applications could be developed.  This course will also introduce the workings and applications of this potentially disruptive technology, by taking Bitcoin cryptocurrency as one of the examples. Furthermore, the potential impact of blockchain technology on the banking and financial industry, governments, contracting and identity management will also be briefly discussed as part of this course.

 

  • Introduction to cryptographic primitives such as hash functions, symmetric/ asymmetric encryption, digital signatures and public-key cryptography.
  • Fundamentals of decentralization, distributed databases and distributed consensus protocols such as Byzantine fault tolerance
  • Consensus without identity using a blockchain, incentive schemes such as proof of work, proof of stake and proof-of-x schemes such as proof-of-publication, time, space etc.
  • Mechanics of Cryptocurrencies such as transactions, blocks, and Bitcoin networks
  • Anonymity in blockchain-based applications with a special focus on anonymity in public and permissioned blockchain applications.
  • Decentralized Institutions, blockchain as a vehicle for decentralization and opensource frameworks for blockchain and smart contracts such as Ethereum and Hyperledger Fabric.
  • Case studies and application scenarios for blockchain-based applications from financial, supply chains and other domains such as cryptocurrencies,user-centric data and identity management and so on.
Description of the teaching methods
This course is a blended-learning course. The lectures will be delivered online but the hands-on exercises and programming workshops will be conducted on campus.


Teaching Materials:
Lecture slides
Readings
Scientific articles
Handouts
Feedback during the teaching period
Quizzes will be used systematically to test student's understanding of the course content at various stages of the course. Oral feedback is given collectively at the lectures based on student answers in quizzes. Additionally, feedback in the forms of question / answers and discussions during the class will be provided.

Student workload
Lectures + Exercises 30 hours
Self study 46 hours
Prepare for the class 30 hours
Project work and report 100 hours
Total workload 206 hours
Further Information

We recommend taking Foundations of Blockchain, Cryptocurrencies and Smart Contracts (KAN-CDSCV1001U) course together with the course Blockchain Business Development (KAN-CINTV1803U). These two courses are complementary and together will benefit students with broader knowledge on the business and technical aspects of blockchain technology. The Blockchain Business Development course focuses on business aspects of Blockchain technology, whereas Foundations of Blockchain, Cryptocurrencies and Smart Contracts course focuses on technological foundations and programming of Blockchain and smart contacts.  The two courses are scheduled one after that other--Blockchain Business Development runs in the 1st quarter and Foundations of Blockchain, Cryptocurrencies and Smart Contracts course runs in the 2nd quarter of the semester.
