A blockchain is a technology that enables records of monetary transactions (called “blocks”) to be transferred across many computers, which cannot be altered retroactively without altering the subsequent blocks. They are typically managed by a peer-to-peer network that decides by consensus to alter a block, making blockchains secure by design.

Blockchains were invented in 2008 to serve as a public transaction ledger of Bitcoin. For learners interested in cryptocurrencies, blockchains are important to learn about due to their role in solving the need for a trusted authority or central server to manage flaws in digital cash transactions.

Though a relatively recent technology, organizations are actively seeking Blockchain professionals. In December of 2018, a report by LinkedIn showed that “Blockchain Developer” was the most rapidly growing emerging job in the United States. Various industries and sectors are looking for specialists in cryptocurrency, including banking, accountancy, oil and gas, insurance, retailers, with particular growth in media, logistics, and legal compliance.

Specific to blockchain, this opens up opportunities for roles as Blockchain Developer, Blockchain Solution Architect, Blockchain Project Manager, Blockchain UX Designer, Blockchain Quality Engineer, Blockchain Legal Consultant, and more that are related.

Blockchain courses offered through Coursera enable learners to gain knowledge on foundational blockchain concepts; skill sets for designing and implementing smart contracts; methods for developing decentralized applications on the blockchain; and information about ongoing specific industry-wide blockchain frameworks. Learners also gain access to courses led by world-renowned experts in blockchain technology, with discussions on design principles, the top 10 challenges of blockchains, and other engaging lessons.

Lessons on Blockchain are taught by instructors specializing in Computer Science, Cryptocurrencies, and more, and are administered via video lectures, readings, quizzes, and more.
