Introduction to Caboose, a blockstore interface to the Saturn CDN network. View video

In this talk, I will present our newly developed testing suite for IPFS gateways, which helps implementers ensure their gateway implementations conform to the IPFS gateway specification. I'll discuss the structure of the test suite, adding new tests, and demonstrate how it is currently being used to verify the Kubo and Bifrost gateway implementations. Additionally, I'll provide a step-by-step guide for setting up the suite in a CI environment, enabling implementers to receive continuous feedback and detailed reports on their gateway's features and compliance with the gateway specification. View video

I'll be talking about how to do CDN incentivization at a protocol level correctly- the game theory is pretty simple and I independently converged on a design pretty similar to the one on Skynet. Adding a simple piece of novel cryptography to the payment channels, and integrating that into the transport layer, reduces latency/RTTs and allows for "delegated payments" where a content creator can send a short commitment to a user to "give them a coupon" for the delivery of a particular file. View video

Dietrich Ayala will introduce the track and then share the latest updates in browser adoption, mobile projects, IPFS in the standards world and more. View slides View video

What is the Web? Interestingly, that question has never been answered before. This talk proposes that the Web is about user agency, and Web technology is the set of technology that increases user agency. I'll explain the reasons for taking this view, and show how that maps to technical architecture and gives us a sense of where to take the web next. View slides View video

Want to write p2p apps, without worrying about identity, storage, encryption or access control? We'll describe how to write an app on Peergos using standard HTML5, and how they work in existing browsers and how users and their data are protected. View slides View video

The WebNative File System (WNFS) empowers users with extensible metadata, file and directory history, conflict resolution, and encryption with fine-grained access levels. We show a rough outline of what its design goals are, how it works, our roadmap, and possibly a demo of our new rust implementation. View slides View video

The web security model relies on a combination of mechanisms to provide origin isolation and prevent some classes of attacks: the Same Origin Policy and Content Security Policies. While effective for their goals, these mechanisms also have side effects that prevent legitimate applications to be built on the Web. In this talk we'll explore how content based addressing can be leveraged to build different security models that enable a new class of Web apps. View slides View video

ODD.js is a toolkit that allows you to build a distributed web application where the user is in full control of their data thanks to WNFS and UCAN. We’ll take a look at which additional layers are built on top of WNFS and how UCAN is utilised throughout this. ODD.js is built by the folks at Fission, but that doesn’t necessarily mean your web application is tied to the Fission infrastructure. This SDK allows various components to be customised and swapped out, as we did with Walletauth, where MetaMask is used as the identity layer. View slides View video

This talk will go over what IPLD Prolly Trees are and how they can be used to build efficient Peer to Peer Databases which can query large amounts of data using built in indexes. View slides View video

Introduction to Fireproof, features, goals, codebase, use-cases View video

There are a number of emerging streams of data that does not need to meet the same ‘consensus’ bar as what we would expect in a global chain(Filecoin). Pando is a huge forest of IPLD data structures and aggregate tons and tons and tons of data around Filecoin and then over time. There are nice properties of having this sort of data network more tightly linked to the chain that seem desirable to encourage, and this leads to the goals for the Pando: Keep included metadata consistently available Provide light-weight, unbiased access to metadata * Discourage historical revisionism. View video

Shifting storage and compute toward the far edge reflects an extreme departure from traditional cloud-based architectures, bringing with that shift a new set of challenges for application developers. Rhizome is a decentralized database for InterPlanetary Linked Data that embraces these challenges to open up new ways of thinking about consistency, interoperability, and privacy. This talk introduces the ideas underpinning Rhizome, and demonstrates how they come together to empower developers to build and reason about new types of peer-to-peer and decentralized applications.

Introduction to the Content Routing track and an overview of the talks ahead. View slides View video

This talk introduces a new method for making content publishing in the DHT less resource-intensive for large content providers. This technique, named Reprovide Sweep reduces the load of content publication by reproviding all provider records located in the same keyspace region at once. This strategy decreases the number of DHT lookups required for content publication, and the number of connections to open by 80x for a content provider advertising 100’000 CID. The talk will be of interest to those interested in IPFS optimization and improving the efficiency of large-scale content publication and discovery on the DHT. View slides View video

The current state of IPNI, what’s new and where we are going View slides View video

cid.contact is a service that routes content: given a CID it finds providers of it along with metadata on how it can be retrieved. It has been almost a year since the launch of cid.contact. a lot has happened since. This talk goes over the latest and greatest offered by cid.contact, our journey in making it all happen and what's to come View slides View video

The IPFS content routing workgroup aims to improve content routing within the IPFS network by applying an intentional focus on effectiveness of content discovery and delivery mechanisms. We make group decisions around the design and implementation of new content routing protocols, optimize existing ones, and address the various technical challenges associated with decentralized content routing. We'd like to make everyone aware of the important work this group is doing and encourage their participation. View slides View video

Double Hashing for the libp2p DHT has been proposed as an approach to improve libp2p's privacy. The approach, which includes breaking changes to the current DHT, has been discussed at IPFS Thing and Camp 2022. This talk will give a brief update of developments since IPFS Camp and most importantly will lay out the migration plan to the new double-hashing DHT. View slides View video

In this talk I'd like to speak about IPNI's journey to implementing Double Hashing at scale. I'll cover: what double hashing is and what benefits it gives to the user; IPNI and DHT double hashing compatibility; IPNI dataset migration; how we run double hashing in production; issues that we encountered. This talk will be interesting to those who already run IPNI by themselves (as they will want to implement Reader Privacy at some point) as well as to those who are just thinking to participate in the IPNI ecosystem.

I would like to share Starmaps, a tool developed by Protocol Labs that is designed for roadmapping based on Github issues. It is especially good to render cross-teams/projects roadmaps, which is perfect to improve visibility inside the network and communicate dependencies more easily. We have started using it at Fission, and our goal is to have as many projects as possible from the PLN to be rendered in a single Starmaps in which you could navigate and look at the dependencies between projects. I think I would need 5-10 minutes (questions aside) to present this. View video

How do we save the past in a violent present for an uncertain future? How does IPFS challenge, strengthen or endanger digital archival efforts? How is IPFS vulnerable to weaponised design? This talk presents the findings of the 2022 Filecoin-supported collaboration between New Design Congress and Webrecorder, highlighting how the DWeb landscape, its technologies and institutions are out of step with the realities of rising instability and complexity of the 21st century -- and what we can do today to begin to address these problems.

It may seem like there is plenty of time, but IPFS Camp is scheduled for later this fall and a large event such as IPFS Camp, needs quite a bit of planning runway. We need volunteers to be a part of the (content) planning committee. This would require significant investment in terms of time and energy, but you will be rewarding the IPFS Community with a spectacular, well planned event and set us up for future IPFS Camp successes. Additionally, let's think ahead on what content we know we'd like to see, new areas of discussion we think could bridge over to bring in new faces, and companies we'd like to see there who may not have joined in the past. Is there something from last year you'd like to see expanded upon? Let's talk. View slides View video

This session is a discussion circle for people interested or who can commit to organizing IPFS + Friends Cafe community events in their city. The idea is to have a cohort of people who can commit to at least 2x events a year (perhaps distributed equidistant between IPFS Thing and IPFS Camp) to help keep up the momentum in between our two largest IPFS events of the year. miwa (PL) can sponsor a coffeeshop / popup, assist with logistical organization and coordinate some speakers from PL. ex: EthCC is fast approaching, would love someone local to commit to organizing content for a one day or half day IPFS + Friends event.

We all roadmap together. View video

At present, DHT implementations primarily revolve around IPFS. However, it's possible for other applications that leverage libp2p to utilize the DHT without the need to participate in the IPFS DHT and store IPFS data. This presentation outlines a strategy to divide the existing DHT into two parts: a lightweight, multipurpose DHT and an IPFS DHT protocol built on top of it. This proposed approach would enable non-IPFS applications to join the lightweight DHT while running their own protocol on top of it. This would promote interoperability with other applications, contribute to the growth of the libp2p DHT, and enhance the security of all its users. View video
