Put on by the Alchemy team, Alchemy University is a javascript-focused education site, created in partnership with some of the best educators I’ve ever interacted with.

I used to have a group called Chainshot on my list, as they have always been underrated, but Alchemy recently acquired them to make this amazing site!

7. Consensys Bootcamp

The Consensys bootcamp just always knocks it out of the park.

The Consensys team is one of the teams that has been around from basically the start of this whole thing.

They consistently deliver on bringing in some of the best in the space to give guest lectures to the students, have top quality content, and are another bootcamp that I highly recommend to anyone looking to get into this space with a hands-on learning approach, and a team to guide them.

One of the harder pieces in this space is Ethernaut. You need a little bit of a javascript background, but trudging your way through this course will teach you a lot of the ins and outs and “gotchas” of solidity, and is one of the quickest ways to become “advanced” in the ways of solidity.

This was created by the Openzeppelin team, who are top auditors and security researchers in the blockchain space, and they make contracts for people to fork into their projects. Anyone in the blockchain space worth their “salt” knows who Openzeppelin is and how to work with their tools!
