We are developing a proof of concept to port our web app, DeckDeckGo, to the DFINITY’s Internet Computer.

After having validated the hosting and password-less authentication integration, we are tackling the last question of our POC: persisting user data and presentations in the blockchain.

Along the way, we tried out two concepts:

  • a “conservative” one: a data persistence in a single database-like storage
  • a “futuristic 🤯” one: generate a database-like smart contract on the fly for each deck created by a user

In this article I present these two approaches.

Introduction

The scope of this blog post is limited to simple key-value database concepts. That kind of persistence is the one we rely on in DeckDeckGo.
