Blockchain Security Skill Assessment

Assessment - 30 questions

Fundamentals of Blockchain Security

Course - 01:22:00

This course introduces the fundamentals of blockchain security. Early videos describe the foundational concepts of blockchain and how the components of the blockchain are put together to provide these properties. Later videos discuss the cryptography used in blockchain technology, describing how public-key cryptography and hash functions are used in blockchain and their security considerations.
Consensus Algorithm Security

Course - 01:28:00

Consensus algorithms are essential to a distributed, decentralized ledger, where a network of nodes must agree on an official version of the ledger without a central authority. This course describes the underlying principles of consensus algorithms, how two of the primary consensus algorithms work under the hood and how they can be attacked.
Blockchain in Action

Course - 01:17:00

After understanding the different components of the blockchain, it is possible to discuss its security as a whole. This course investigates how blocks are created in the blockchain (and how block creation can be attacked) as well as discussing attacks targeting blockchain nodes and the network that ties them together and enables communication.
Smart Contract Security

Course - 01:43:00

Smart contract platforms are an extension of the original blockchain design, enabling fully functional programs to run “on the blockchain.” This course describes what a smart contract is and explores programming vulnerabilities that exist because a smart contract is a program, runs on a blockchain or is implemented on the Ethereum smart contract platform.
Beyond the Basics of Blockchain

Course - 00:55:00

So far, this learning path has been focused on blockchain-based distributed ledgers. This course goes beyond this view to discuss how the blockchain protocol can be replaced (using different underlying architectures), expanded (with second-layer protocols) or improved (using advanced cryptographic primitives) to overcome some of the limitations of blockchain technology.
