Now have time to get back to the project after PBA. In the first version of the @Polkadot architecture visualization 🥲, I misunderstood the concept of para-validators so I fixed that with a clearer relationship between Relaychain <> Validators <> Parachain.

One of the most common feedbacks I usually receive when introducing Substrate is that it is hard to use. But if you give it a try and put yourself in the protocol developer's shoe, you will understand that Substrate is not like other high-level frameworks like React or NestJS.

@AdamSteeber1 @shawntabrizi As a past PBA student who was instructed by Shawn, I don’t think his contribution to the DOT ecosystem can be counted in the number lines of code or opened Github issues. If so, you should track the Substrate stack exchange and the number of talks, presentation he had as well.
