I'm looking to get involved in the blockchain space over the next year, either by starting or joining a significant venture. I truly believe in the immense value and potential of blockchain, much like the early days of the Internet. A little bit about me: I graduated in computer science from a top university in the USA. I've had experience working with major tech companies like Amazon and Microsoft, as well as startups, including my own venture.

I've also worked in a role at a fintech unicorn, both as an Engineer and Product Manager. To develop a solid plan for my venture, I need to thoroughly understand the basics of blockchain. Concepts like Proof of Work, staking, decentralized exchanges (DEX), and decentralized finance (DeFi) are areas I'm only slightly familiar with. To create a clear vision of what can be achieved, I need to delve deeper into these topics.

Currently, my learning approach is a bit disorganized. I come across interesting topics, search for them online or on YouTube, watch a few videos, and then get sidetracked. This method isn't the most efficient. I would greatly appreciate it if someone could recommend some structured courses that offer a comprehensive dive into blockchain, Ethereum, and cryptocurrency.
