Web 3.0 Crash Course 👽

Hey bubblers,
Matteo here, founder of Superbuild.io.

I spent countless hours studying web3, joining/analysing 50+ NFT communities, talking with dozens of web3 founders on Discord and testing new crypto products.

So far, I have 3 takeaways:

  1. This is the most important tech trend since the Internet came out
  2. The space is really confusing: you need a smart friend to explain that stuff to you
  3. It’s changing fast, and you need to have a strong understanding of the fundamentals to keep up with new things that get launched every day

I feel like I got back to college.
My Notion’s workspace is full of notes, lists of promising NFTs, DAOs, Social Tokens, trends, web3 products, crypto-related pain points and every week, I add like 50 new resources.

Because of this, I created a video course where I break down all these topics providing real business examples and (OF COURSE!) introductions to Bubble (with plugins you can use to build your web3 apps.

Link to the course Superbuild.io/web3

Here is the index/structure:

  1. Pre Web 3.0

    • Web 1.0
    • Web 2.0
  2. Web 3.0

    • Web3 architecture (decentralized)
    • How identity works
    • Wallets and native payments
    • Ownership
      • DAOs, grants, community ownership, social tokens & NFTs
      • But also data…
    • How it’s different from Web 2.0
    • Transition from marketing to community
  3. Projects that make sense with Web3

    • Communities
    • Crowdfunding
    • Marketplaces
    • Creator economy
    • Metaverse (Avatars - NFTs - Crypto wallets)
    • Verification Services - i.e. events tickets, education, jobs
  4. Where it doesn’t make sense to use Web3

    • Web3 has some limitations (and opportunities for web3 founders) right now:

      • Scalability – transactions are slower on web3 because they’re decentralized. Changes to state, like a payment, need to be processed by a miner and propagated throughout the network.
      • UX – interacting with web3 applications can require extra steps, software, and education. This can be a hurdle to adoption.
      • Accessibility – the lack of integration in modern web browsers makes web3 less accessible to most users
      • Cost – most successful dapps put very small portions of their code on the blockchain as it’s expensive (GAS fees)
    • Sometimes centralisation is a good thing

  5. How can you use Bubble and plugins available in the marketplace to develop a web3 project?

    • Introduction/why Bubble
    • Identity & Wallet management (Bubble plugin)
    • Smart contracts creation (Bubble plugin)
    • NFT marketplaces template and APIs (Bubble plugins)

I’ll drop here the link to the course Superbuild.io/web3

Enjoy the digging… :hole::rabbit2:


Can’t wait for this course!! :blush:

Is the course free?

Discord community has some free channels, apart from that you can check the pricing on the landing page!

Very cool!
Web3 is the future :rocket:


Hey Everyone :wave:

I’m a co-contributor on this course with Matteo, and I wanted to update you that after countless late night and little sleep, we’ve pushed the course live on superbuild a few days ago. :clap:

So far feedback has been awesome :pray: so we’d love you to check it out if you’re keen to learn more about web3. :rocket: The launch sale is still on, but only for a limited time :clock1:

All up we have ~2 hours of content. In addition to running through the basics, we do spend a decent amount of time talking through specific things you can build in Bubble today, with some solid time spent in the Bubble editor showing:

1. Sign in with wallet (Metamask). This means you can authenticate users just using their crypto wallet (no email/social authentication required). This workflow could also help you to easily build blockchain based DocuSign functionality into your app as well :ok_hand:

2. Accepting crypto payments :money_mouth_face: in your app. This is perfect for someone wanting to either avoid traditional payments (i.e. stripe) or simply adding this as another payment method to your existing app.

We’ve also partnered with Bubble on a special perk :gift: So head on over to our course page to view a breakdown of the content, details on that perk, and to get access to the course.



Great great course!


Hehehehe…money laundering for the masses! You don’t have to be a big drug cartel to launder like the Ozarks.

I’m not sure I’m completely kidding on this one.

The course is really well made, from the explanation of web3 topics to how to build a no-code application based on it.
Also, the Discord community is a great place to discussed with the other members of the community~

@aaronsheldon you’re not wrong - this is definitely happening in crypto at the moment, but I doubt it’s going to remain the case as things become more mainstream. Particularly once central banks start issuing their own digital currencies (CBDCs)

It’s kinda how these things work though right. Things get pushed out all the time with limited controls > people take advantage > controls are tightened.

Right now, while there are some big numbers in crypto and it’s a very quickly growing market, it’s still a very small % of the overall economy. So I’m sure governments care, but it’s probably not their number one issue to tackle.

A great example is online credit card fraud. In the beginning (I assume, not being a fraudster) it was pretty easy to charge up someone’s credit card and get away with it, and banks probably didn’t care all that much given it was a splash in the ocean vs. the total payments they handled.

Fast forward a few years and it became a big number, so naturally they threw resources at solving the problem.

Will be the same with a lot of the nefarious activity happening in crypto at the moment. You can always count on the tax man finding a hole in his pocket.

Just my two cents anyway


I hope so. However, putting my black hat on for a moment:

Because of the ease with which public-private key pairs for wallets can be generated, and that the subset sum problem is exponential it will likely always be very easy to obfuscate cash flows through block-chains. And if you are willing to wait for the transfers to drip through, you can protect against timing attacks on identity. Further, if I wanted to really camouflage the transactions from outlier detection I would randomly sample from the empirical distribution of transactions already recorded in the public ledger. The only point regulators can really tackle is the entry point of fiat currency into cryptocurrency. Once in, the transactions can be sheltered very easily.

Realistically our global climate crisis and depleting extract-able energy sources are going to put a damper on cryptocurrencies long before tax regulators do. In the meantime I’m willing to wager that a significant part of the prepaid credit care market is really just smurfing for money laundering.

I agree with you that this might be the case now, but this is changing and will probably burn a lot of people in retrospect.

If you take the example of a drug dealer who is selling drugs on the dark web and getting payment in crypto from their customers… They don’t really have the issue of needing to verify their identity to get fiat currency into an exchange - their customers do that. So they could spin up as many wallets as they like to receive payment but here’s the problem…

What do you do with that crypto?

  1. You can’t easily transfer it into fiat currency and go and buy a new Rolls-Royce because of the KYC requirements when you’re trying to take the money out.

  2. You could buy goods and services with crypto, and while not many places accept crypto today it’s growing. But at some point someone will be able to match your identity with your wallet unless you’re only dealing with equally as questionable people.

Either that master wallet (if you’re stupid enough) where you received all of the drug money OR somewhere down the chain with some layering. Then all of your previous transactions will be unmasked - which is exactly where the regulator can step in and you’re burnt.

So you kinda end up in a similar situation to today, where it’s really difficult to deal with ‘dirty’ money and use it to buy legitimate things. Although the big difference is it’s so much easier for regulators to follow the ‘paper’ trail with crypto.

I fully expect there are people enjoying the high life today, doing all sorts of shady business with crypto in plain sight… But someone may come knocking at the door months or years from now.

Climate Impacts

To your second point re: climate impacts. Well a lot of the early blockchains are hugely inefficient as they’re using computer-intensive proof-of-work (PoW) models, and this is why the transaction costs are going through the roof and there’s a huge climate impact.

Newer blockchains (and Ethereum is transitioning) are using a more efficient proof-of-stake (PoS) model which is far less energy intensive. People are also using layering to shift intensive tasks of the main chain, do what they need to do and then come back again.

But despite me defending web3 technologies, I’m not someone who is heavily invested in crypto or anything like that. There’s lots of shady stuff going on, and there’s also a lot of people trying to throw this technology at every problem, which is kinda stupid.

I really believe the future is web2.5 and a lot of this stuff is going to come in and disrupt the way we do things today, but it’s not going to wipe out and replace everything.


We discuss a lot of these sorts of topics and issues in the crash course, in addition to hands-on time in the Bubble editor implementing web3 workflows :grinning:

This is really a very comprehensive course. This is the best choice when you want to get a general understanding of NFTs and blockchain, but also opens up the possibilities of how to create your own product with Bubble. This is exactly what I was searching for!
