Blockchain is one of the most in-demand technologies and one skill that you should learn in 2021. It will not only help in your career but also raise your profile.

I have been sharing a lot of courses and tutorials in this blog about what to learn in 2021, starting from tools to frameworks, from libraries to programming languages, and one of the most critical technology, you can learn in 2021 is Blockchain technology. It's one of the most talked-about technology at the moment and considered to be the next big thing after the invention of the internet as they provide a way to attain digital trust on the Internet.

Though, I must say that the crazy rally of cryptocurrencies has a considerable role to play in making Blockchain accessible. I know about Bitcoin for a long time but never invested in it, and the same goes for Blockchain.

Even though I knew about it, I never thought of learning Blockchain development and writing tutorials about it, until I realize this may be the time to learn Blockchain. There is so much emphasis on Blockchain development as companies from finance, real estate, healthcare, and other sectors are very keen to learn about Blockchains and adopt them.

Venture capitalists are currently diverting a lot of investments into funding Blockchain-based companies, which means there could not be a better time to learn about Blockchain than this year, and there is no better way to start with free online courses.
