I predict that “web3” will be an even more nebulous term than “cloud” and “web 2.0”. Anyone pitching a product will say it’s web3. If you have an idea for blockchain technology or anything that vaguely supports decentralization and also can put money into investor pockets, this is the time to make it.
It's a free course, you can complete it in roughly 6 hours, in very bite-sized chunks that pretty much anyone with prior programming experience can follow, and has some very good information about the unique quirks of smart contracts (although keep in mind it uses an older version of Solidity and I've already discovered a change in syntax since the version it has on there, i.e. array.push returned the new length of the array in older versions of solidity, but doesn't return anything in newer versions[2]).
The tech stack is still evolving and a bit of a moving target, with new tools and tech coming out periodically, but it's pretty interesting, and there's not a ton of people developing in the space so it's not terribly hard to find a project to work on once you get the basics (I stumbled into one by chance myself).
I think at some point most companies will probably want to incorporate this tech into their websites to a certain extent, at least connecting to a wallet as an identification option, if nothing else. And in the meantime there's potentially some easy ETH to collect from all those NFT projects for a relatively small amount of work.
It's definitely wild west, though, and I'd be careful accepting work from random people online asking for work in it, without getting some sort of payment up front, as there's plenty of scams and 'rug pulls' out there (seemingly legit, but then just disappear after taking everyone's money[3]).
It also completely opens the door to remaking all the same software, but this time it's new because it's based on the blockchain, so you can possibly get visibility amongst a sea of other apps because of that. Like I know a guy working on a web3 Patreon, and there's things like Clarity.so that's basically like a Trello board but utilizing some Web3 features.
Pick a site, any site, and you could make a web3 friendly version of it if you wanted to. Doesn't mean it'll be successful necessarily, but you'll probably have a better shot than if you just tried to convince people to stop using Tiktok.
I'm kicking around the idea of making a Web3-enabled web game portal/api myself. I have a few ideas I haven't seen done by anyone else yet that I think players would appreciate.
