Slides

What we covered

Most of the engineering in a Web3 product is not on-chain. It is the system that watches the chain, absorbs bursts, and answers queries fast enough to feel like a normal app. That system is what we build.

  • The Web3 challenge stated plainly, and where cloud infrastructure is the answer to it.
  • Listening to the chain with Infura, and what happens when the feed hiccups.
  • Decoupling ingestion from processing with Pub/Sub, so a burst on-chain doesn't take the app down.
  • Workers and caching: turning a stream of raw events into something queryable.
  • Choosing the right Google Cloud database for the access patterns you actually have.
  • A Kubernetes-based architecture on GKE, and how to split the backend across it.
  • The other GCP services worth knowing about before you build around their absence.
