Hello again, fellow Protonians!

I have another question about building on Proton:

Is the role of a database (e.g. PostgreSQL, MongoDB ) obviated to some degree when building on top of a blockchain? What does the blockchain do better in this regard?

Hello, fellow Protonians!

Proton is a fabulous blockchain, with ambitions for mass adoption. It's a vision that will attract developers.

Question: what technology stack should a developer be familiar with in order to build apps for mass adoption using Proton?
