Begin your journey in the formation of blockchain technologies with a look at basic blockchain concepts, along with an application where blockchain technology plays a central role—cryptofinance. This course also introduces distributed digital systems in terms of software and network architecture, and shows how these systems form the basis for blockchain functionality. In this course and subsequent courses in this specialization, you will have the opportunity for hands-on practice to reinforce your learning.
Continue learning about blockchain technology by exploring the nature of ownership and how blockchain is one way to approach decentralized transaction management. This course simplifies cryptography and hashing, which are critical for authenticating users and ensuring transaction privacy.
Apply what you learned about cryptography and hashing in previous courses to the Merkle tree, which is the basis for the process of adding new blocks—representing new transactions—to the blockchain. This course also introduces the concepts of proof of work and proof of stake, which play an important role in ensuring the integrity of the blockchain.
Learn how blockchain verifies transactions and distributes data to peers—nodes connected to the network. This course shows how multiple versions of blockchain integrate into a single unit, discusses the limitations of blockchain, and explores the enterprise applications of blockchain technology.
