IPFS / IPFS Camp 2022 - IPFS 201: App Design Patterns and Developer Tools

The lead maintainer of js-ipfs and js-libp2p will share tips and tricks for debugging js-ipfs

This panel talk was given at IPFS Camp 2022 in Lisbon, Portugal.

Most people aware of Berty won't know that we've made an underlying protocol that could power many other projects. We want to change that and help more builders to create powerful dApps. Let's look at what problems we're addressing and how.

Learn about Fission’s process of going from protocol to product, while creating composable specs and libraries that help with interop and re-use across the ecosystem.

Demo the Webnative SDK, an edge computing stack.

Thoughts on interop & the magic of UCANs.

Dapps are all the rave, but there's no consensus about how they should be built.

There's a cambrian explosion of developer tools and many emerging design patterns using IPFS. This introduction will set the stage for some of the fantastic speakers we have during the day who'll be sharing the state of the art in app design patterns and developer tools.

Tableland is a decentralized network for relational, composable data — powered by smart contracts + SQL. Mutable data with immutable rules, on EVM chains like Ethereum, supported by tools and protocols like IPFS, Filecoin, and more

Merkle-DAGs are fun, but even more when they can be used to compute an ever-evolving state (i.e. a database) collaboratively maintained by a set of peers that may come and go as they please. Join us to learn about Merkle-CRDTs, what use-cases they fit and how they power things like IPFS Cluster pinset distribution.

Learn how content addressed user-centric protocols like IPFS, DID, and UCAN will change the web, and how to build Node.js applications using them.
The web3.storage team will share the latest APIs and walk you through building your own application data model. Start with DID-based self-sovereign auth, a great opportunity to learn about the next wave of digital identity, and write code to upload files as well as JSON objects. They'll discuss IPFS data structures like IPLD trees and graphs, and how they can be used in applications.

Banyan is a tree data structure that provides an indexed, compressed and encrypted append only log.
It is used in a distributed event sourcing system at

This talk will describe the journey followed from research to implementation of a distributed clone of Vine—the GIF sharing app. It will touch on the p2p aspects of the app, the nature of distributed apps, and how a blockchain layer is optional when building distributed apps. Then it will continue explaining the high-level plan for the app and the goals that were set.
Finally, it will touch on the implementation details, the dragons, the groundwork, the how-tos and gotchas of using a shared data structure (CRTD) between peers, and a demo of the gif-sharing app.

In this talk, we'd like to share the ideas and technical approaches we came up with while building Mintter on top of IPFS for the past 2.5 years. Some of the challenges we faced didn’t have easy, or plug-and-play solutions at the time, such as multi-device, decentralized identity, version control, etc.

Mintter is a hypertext system for knowledge management in open discussion groups. While working on the product, we were greatly inspired by the work of the founding fathers of hypertext: Doug Engelbart, Ted Nelson and others.

Local-first software design is almost opposite to traditional models. Software built this way has some clear advantages for a large application set but isn't without its challenges.
We'll take a look at replication of Merkle-CRDT replicas using pinned IPNS/IPFS and conclude with a demo of  Opal (https://github.com/cypsela/opal)  +  Zzzync (https://github.com/tabcat/zzzync) .
