Secure Scuttlebutt Consortium

Secure Scuttlebutt

Secure Scuttlebutt (SSB) is a peer-to peer communication protocol, mesh network, and self-hosted social media ecosystem.[3][4] Each user hosts their own content and the content of the peers they follow, which provides fault tolerance and eventual consistency.[5] Messages are digitally signed and added to an append-only list of messages published by an author.[6] SSB is primarily used for implementing distributed social networks, and utilizes cryptography to assure that content remains unforged as it is propagated through the network.[7][8]

The Heart of Spritely: Distributed Objects and Capability Security

This paper is the second in a three-part series outlining Spritely's thinking and design. The first paper, Spritely: New Foundations for Networked Communities, explains the problems which face contemporary social network design. This paper details the core technical toolbox provided by Spritely Goblins and how it supplies the necessary features to feasibly build out Spritely's broader vision. The third paper in the series, Spritely for Secure Applications and Communities, ties the first two papers together by showing how the architecture for user-facing software fulfills the vision of the first paper and can be built on top of ideas from this paper.

FEP-1042: Peer to Peer Fediverse Identities

Hey folks, we at [Distributed Press](https://distributed.press) have been working on making a bridge between peer to peer or "dweb" protocols and ActivityPub implementations over the past year and wanted to solidify our approach so that others can interoperate. Here's is an initial draft expla...

An analysis of social network-based Sybil defenses

Recently, there has been much excitement in the research community over using social networks to mitigate multiple identity, or Sybil, attacks. A number of schemes have been proposed, but they differ greatly in the algorithms they use and in the ...

Bluesky and the AT Protocol: Usable Decentralized Social Media

Bluesky is a new social network built upon the AT Protocol, a decentralized foundation for public social media. It was launched in private beta in February 2023, and has grown to over 10 million registered users by October 2024. In this paper we introduce the architecture of Bluesky and the AT Protocol, and explain how the technical design of Bluesky is informed by our goals: to enable decentralization by having multiple interoperable providers for every part of the system; to make it easy for users to switch providers; to give users agency over the content they see; and to provide a simple user experience that does not burden users with complexity arising from the system's decentralized nature. The system's openness allows anybody to contribute to content moderation and community management, and we invite the research community to use Bluesky as a dataset and testing ground for new approaches in social media moderation.

SybilLimit: A Near-Optimal Social Network Defense against Sybil Attacks

Decentralized distributed systems such as peer-to-peer systems are particularly vulnerable to sybil attacks, where a malicious user pretends to have multiple identities (called sybil nodes). Without a trusted central authority, defending against sybil attacks is quite challenging. Among the small number of decentralized approaches, our recent SybilGuard protocol [H. Yu et al., 2006] leverages a key insight on social networks to bound the number of sybil nodes accepted. Although its direction is promising, SybilGuard can allow a large number of sybil nodes to be accepted. Furthermore, SybilGuard assumes that social networks are fast mixing, which has never been confirmed in the real world. This paper presents the novel SybilLimit protocol that leverages the same insight as SybilGuard but offers dramatically improved and near-optimal guarantees. The number of sybil nodes accepted is reduced by a factor of ominus(radicn), or around 200 times in our experiments for a million-node system. We further prove that SybilLimit's guarantee is at most a log n factor away from optimal, when considering approaches based on fast-mixing social networks. Finally, based on three large-scale real-world social networks, we provide the first evidence that real-world social networks are indeed fast mixing. This validates the fundamental assumption behind SybilLimit's and SybilGuard's approach.
