What Does the Blockchain CBSP Certification Exam Cover?
A Certified Blockchain Security Professional should have experience with the following topics before you sit for the exam:
Blockchain development: This includes evaluating existing technologies and proposing new ones in order to improve blockchain security. After all, what good is a blockchain if it has a low level of security? Algorithms and cryptography: You will need to be able to evaluate the various algorithms that are used within blockchain technology. They all have their own pros and cons, which can affect block creation time, data integrity, and mining difficulty. The UTXO registry: This section covers how transactions are organized on the network in an immutable form. Users will create these transactions according to their respective wallet addresses. The consensus protocol: You will need to be able to explain the various validating methods that are used within blockchain technology. These methods help maintain increasing network participation and handle transaction time, data integrity, and transaction scalability.
