Swarm feeds cleverly combine single owner chunks into a data structure which enables you to have static addresses for your mutable content. This means that you can signpost your data for other Bees, and then update at will.
Although it's possible to interact with feeds directly, it can involve a little data juggling and crypto magic. For the easiest route, see the bee-js feeds functionality and swarm-cli, or for the super 1337, share your implementations in other languages in the #develop-on-swarm channel of our Discord Server.
A feed is a collection of Single Owner Chunks with predicatable addresses. This enables creators to upload pointers to data so that consumers of the feed to be able to find the data in swarm using only an etheruem address and topic id.
Swarm's feeds provide the ability to update your immutable content in a mutable world. Simply reference your feed's
manifest address as the
content hash in your ENS domain's resolver, and Bee will automatically provide the latest version of your website.
Feeds are a hugely versatile data structure.
Use swarm-cli to store a file at the same location, and update whenever you like without changing the address.
