What Actually Changes?

Same app. Different backend. Completely different rules.

Once you remove the single admin from the equation, everything shifts; how users log in, how data gets written, who controls the logic. And if you're coming from Web2, this is the moment it all starts clicking.

In this video we map out exactly what changes layer by layer:
- The 4-layer Web3 stack every builder needs to understand.
- What replaces your login system, your backend, and your database.
- Why blockchains need indexers (and what that even means).
- The real trade-off between speed and shared truth.

Web3 isn't "no servers." It's just different servers and once you see the architecture clearly, building on it stops feeling like a leap of faith.

This is Episode 2 of Decode: The Builder Journey, a course by Beenco Labs taking you from blockchain basics all the way to deploying on-chain.

If you missed Episode 1, go watch that first https://youtube.com/shorts/wXI1Y158oAU?si=B306b-cHOKzsxL_O. This builds directly on it.

Follow the series. The next one gets into hashing and why it makes blockchain history basically tamper-proof.

Ready for the next one whenever you are!
