DOP 322: How to Build Apps That Never Go Down Even When Servers Die

#322: Peer-to-peer technology represents a fundamental shift in how we think about data sovereignty and application architecture. Rather than relying on centralized servers and trusting specific endpoints, peer-to-peer systems allow users to verify data authenticity regardless of its source. This approach eliminates the traditional point-to-point communication model where data flows from a specific server to your device, instead creating networks where any peer can help distribute content while maintaining cryptographic verification.

The technology offers compelling advantages for developers and users alike. Applications built on peer-to-peer foundations can operate without ongoing infrastructure costs, scale naturally as more users join the network, and continue functioning even if the original company disappears. Development becomes simpler in many ways since everything runs locally by default, eliminating complex database configurations and external dependencies. However, challenges remain around debugging distributed systems, ensuring data persistence in small networks, and adapting traditional development workflows to this new paradigm.

In this episode, Darin and Viktor explore these concepts with Mathias Buus Madsen, co-founder of Holepunch and creator of the Pear Runtime. Mathias shares insights from building real peer-to-peer applications, including their chat app Keet, and explains how developers can start experimenting with this technology today.
