Adam & Mathias present progress so far for the sig0lease project at Berlin FediDay 2026.

On Sunday September 13th, Adam Burns and Mathias Jud held a workshop at the 2026 edition of Berlin FediDay entitled The fediverse at the edge (of time): sig0lease and devuan-pi-gadgeteer.

The presentation explained how sig0lease allows time-based leasing and updating of hostnames in the Internet’s Domain Name System (DNS) together with publication of service descriptions and service discovery information for services offered by each host joining the local network.

🚧 Work in progress

sig0lease is a proxy DNS server and client that enable a real-time collaborative and secure method to publish wide area DNS Service Discovery to communities across the Internet. Standard SIG(0) key based authentication allows users to register and refresh their service discovery information as required.

📝 Prepare

Install dependencies.

To keep extra dependencies to a minimum and to allow use in constrained environments, these tools are implemented in Bash and use a subset of BIND9 DNS tools.
