Beyond Swapping Bits
Accelerating file-sharing in P2P networks and IPFS with Bitswap
Bitswap is a Block Exchange protocol designed for P2P Content Addressable Networks. It leverages merkle-linked graphs in order to parallelize retrieval and verify content integrity. Bitswap is being used in the InterPlanetary File System architecture as the main content exchange protocol, as well as in the Filecoin network as part of the block synchronisation protocol. In this work, we present Bitswap’s baseline design and then apply several new extensions with the goal of improving Bitswap’s efficiency and efficacy and minimizing its bandwidth fingerprint. Most importantly, our extensions result in a substantial increase to the protocol’s content discovery rate. This is achieved by using the wealth of information that the protocol acquires from the content routing subsystem to make smarter decisions on where to fetch the content from.
This talk is focused on sharing the operation of Bitswap, the testbed we build to test improvements of Bitswap, and the ways in which we improved Bitswap building the foundation for research lines on file-sharing in P2P networks.

Fluence is an open application platform powered by peer-to-peer computing protocol and a decentralized licensing system. Fluence enables developers to host applications in the decentralized network and collaborate on live applications, reusing components and data. The protocol creates an open marketplace of compute capacity, so availability and pricing are not controlled by a single company and instead are driven by competitive market forces. Applications are faster to build, easier to ...

Fluence is an open application platform where apps can build on each other, share data and users. Fluence not only allows hosting services inside p2p network but also provides JS SDK for building web applications, which communicate with the services. After the introductory talk, we will dive right into something very practical. We will demonstrate the process of making a web application with Fluence JS SDK. We will start with an empty create-react-app project and work our way towards the fully ...

Aquamarine is the multi-process composition medium based on pi-calculus, designed for distributed applications/backends, both in private deployments and open networks. Aquamarine scripts define the topology of the execution (when and where to move control flow) and data dependency graph (what results and what arguments to pass where), essentially describing the composition of (micro)services, e.g. using one service's output as another service's input. The language primitives are based on ...

Matrix (https://matrix.org) is an open protocol for secure, decentralised communication - defining an end-to-end-encrypted real-time communication layer for the open Web suitable for instant messaging, VoIP, microblogging, forums and more. We introduced P2P Matrix at FOSDEM 2020, and throughout 2020 we've been working on improving P2P Matrix. This includes massively improving Dendrite, our next-generation Matrix homeserver implementation, implementing P2P Element for genuine mesh networks on iOS ...

Today computer systems are often built with an implicit hierarchy. It can be seen as a way to enforce existing power structures. The very act of making software entails describing exactly how the system can be used and for what. Furthermore, ever more data about the usage of systems is gathered. This combined with machine learning has given rise to a whole new class of systems that can be very hard to reason about. Especially given that the data or the algorithms can be controlled or bought by ...

Welcome to Scuttlebutt! A walkthrough and introduction to the Scuttleverse. Here we explore real life projects and guide you in connecting with the main network. A hands on workshop for those looking to try out Scuttlebutt. Like other social platforms, you can send messages to your friends and share posts onto a feed. The cool thing is that the underlying technology here means that messages are passed directly between friends via a peer-to-peer (p2p) gossip protocol. As a decentralized social ...
