This session explores what it means to build the open social web from the edge: across mesh networks, mobile devices, peer-to-peer systems, and the social protocols that allow people to communicate, coordinate, and organize outside centralized control.

Too often, conversations about the open social web stay at the level of applications, protocols, or abstract ideals of interoperability. But if we are serious about resilience, freedom, and real-world usability, we have to think across the full stack. It is not enough to have an open or decentralized social application if the infrastructure underneath it still depends on centralized hosting, fragile connectivity, or assumptions that break down in low-resource or high-risk environments. At the same time, it is not enough to build network infrastructure without tools that people can actually use to communicate, organize, and act together.

This session is about bringing those layers together.

Using examples including BitChat, Agora, White Noise, and Divine, we will explore how different projects can connect Bluetooth mesh, peer-to-peer communication, open social protocols, and alternative coordination models into a more resilient social and communications stack. These projects work across multiple protocols and technical layers, including Bluetooth, Nostr, Bitcoin, and other open systems, in order to support communication and coordination where traditional infrastructure may be unavailable, unreliable, or unsafe.

One core example is BitChat, which uses Bluetooth low energy mesh to turn phones themselves into nodes. Instead of requiring specialized hardware, the crowd becomes the cloud: people’s existing devices create the network. This helps bridge what are often treated as separate domains: decentralized hardware and the open social web. It shows how communication systems can be designed around the tools people already have in their pockets, rather than assuming access to specialized equipment or stable internet connectivity.

Another example is Agora, a project developed in response to needs from pro-democracy activists and designed around peer-to-peer fundraising and coordination in constrained environments. Its story raises broader questions about what freedom tech looks like in practice: how technical architecture, political context, and community need shape one another, and how systems can be designed to be harder to capture, censor, or disable.

Together, these examples offer a way to think about the open social web not just as an interoperability problem, but as an infrastructure problem, a usability problem, and a political problem. What does it take to build systems that work across multiple layers of the stack? How do we design communications infrastructure that remains useful when connectivity is limited, centralized services fail, or state and platform power become points of control? What does it mean to build social technologies that are genuinely resilient, rather than merely decentralized in theory?

This session will examine those questions through a practical, project-based lens. We will look at how different technical components fit together, how design choices affect accessibility and adoption, and what tradeoffs emerge when building for low-resource, adversarial, or fast-changing conditions. We will also talk about the broader implications for freedom tech: how open social systems can support activists, journalists, organizers, and communities that need tools for communication and coordination without relying on institutions that may not serve their interests.

The session is intended for technologists, organizers, designers, protocol builders, and anyone interested in the future of decentralized communications. It will be accessible to people who are not deeply technical, while still offering substance for participants working directly on networked systems and open protocols. Rather than focusing on one protocol or one layer of the stack in isolation, the session offers a cross-layer view of what resilient, peer-driven social infrastructure can look like in practice.

Participants will leave with a stronger understanding of how mesh, mobile, peer-to-peer, and open social technologies can reinforce one another; why low-resource and anti-authoritarian contexts expose weaknesses in conventional technical assumptions; and how freedom tech can move from abstract principle to operational reality. Ultimately, the session invites participants to rethink the open social web not as a single application layer, but as a living ecosystem of devices, protocols, communities, and practices built from the edge outward.
