1.1 KiB
This guide will help you understand how to publish and resolve resource records using 0.Introduction.
Publishing Resource Records
To publish resource records for your key, you need to sign a small encoded DNS packet (<= 1000 bytes) and publish it on the DHT. This can be done through a relay if necessary.
Resolving Resource Records
To resolve some key's resources, applications can query the DHT directly or through a relay. They will then verify the signature themselves.
DNS Queries Over HTTPS
Existing applications unaware of 0.Introduction can make normal DNS Queries over HTTPS (DoH) to 0.Introduction servers.
Caching and Scalability
Clients and 0.Introduction servers cache records extensively to minimize DHT traffic and improve scalability. The DHT drops records after a few hours, so it's important to republish records periodically.
