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?

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?
