Server components for web3 apps

Tutorial description

After this tutorial, you will be able to write TypeScript servers that listen to events on a blockchain and respond accordingly with their own transactions. This will enable you to write applications that are centralized (because the server is a point of failure), but can interact with web3 entities.

@qbzzt Interesting... so would these "server components" be like front end components? Or more of an API that is listening to events and capable of responding with actions?

[qbzzt]

They can be either. I'm thinking of a use case that requires listening to events, but it can be triggered by any other input too.

Gotcha, I see what you're getting at here. Sounds good from my end!

Written (#13228). Next, I'll submit a proposal for a sequel that teaches how to use zero-knowledge proofs for a centralized component that holds a secret state and can be trusted (#13234). Do you think it's better to use Zokrates or Cairo?

@qbzzt Not sure personally as these aren't tools I have familiarity with; feel like I've heard more about Zokrates lately though, but I'll let you be the judge.
