Built with, not just built on

Solar Punk's communication work centers on DevCon.buzz — a conference social app with chat rooms, threads, and emoji reactions, running entirely on Swarm. The underlying swarm‑chat-js library is open source. The longer-term vision is Signal on Swarm: end-to-end encrypted messaging using the X3DH and Double Ratchet, fully decentralized, fully serverless.

A fully decentralized, anonymous forum hosted on Swarm. Post images, text, and links across threads. Originally accessible only through local nodes; now available via the gateway at bchan.bzz.limo. Built by the Foundation's own team as a proof of concept for open, censorship-resistant public discourse.

Datafund's MCP (Model Context Protocol) server lets AI frameworks treat Swarm as durable memory — agents can buy storage, write immutable logs, and maintain mutable state via Feeds, live at provenance.datafund.io.

Swarm MCP is the standard adapter that lets AI frameworks treat Swarm as durable memory — agents can buy storage, write immutable logs, and maintain mutable state via Feeds. The Hashgraph Desktop plugin and ElizaOS plugin are both shipped. The x402 payment protocol, demoed at the January 2026 Community Call, adds a native pay → upload → share flow for AI economies.

Datafund's provenance toolkit — gateway, CLI, and MCP server — attaches verifiable metadata to data stored on Swarm, creating an immutable audit trail for where training data came from and how models were produced. Also building Hubee Registry, a public decentralized registry for AI models and datasets with live on-chain accessibility. Swarm fellow since December 2024.

Professor Toomas Klementi from Tallinn University of Technology presented at the December 2025 Solstice Call: a self-sovereign sensitive data wallet for scientific and health data. ACT manages consent cryptographically — access can be granted or revoked without trusting any intermediary. Swarm stores the encrypted pieces; the user keeps the key.

Fair, location-aware hydrogen trading platform. Uses Swarm to store and retrieve Production Certificates and Guarantees of Origin — documents that prove clean energy provenance across supply chains. Censorship-resistant infrastructure for records that need to outlive the companies that created them.

Offline data archiver bringing Wikipedia and other open knowledge to Swarm. The full Wikipedia archive is stored on the network and accessible via Swarm Desktop. Partnership since 2022. The OpenStreetMap archive is also maintained on Swarm, as a tribute to community member ldeffenb who built and maintained it.

Coordinated network building infrastructure and dApps for a fairer data economy. Promotes digital sovereignty and human rights through decentralized technology.

Building IPSH — an IPFS-compatible protocol that exposes familiar endpoints while persisting data on Swarm. Positioned as a practical alternative to centralized pinning services: meet IPFS developers where they are, offer real persistence guarantees. Also HejBit: Swarm storage for Nextcloud and WordPress without wallets. Both open source.

A portable identity layer for Swarm applications: master identity → personas → session keys. Accounts via Ethereum wallet or passkey; multiple identities under one account; local and network-synced modes. APIs cover chunks, files, feeds, and ACT. Demoed live at the February 2026 Community Call.

P2P verifiable computing network where clients announce compute needs and servers respond with offers. Integrates Swarm for decentralized storage of compute artifacts, results, and provenance records.

Built a custom Swarm storage driver for Docker registries — container images stored and distributed via Swarm.
