This is an update to a Summer 2024 blog post. At the time, atproto relays required a cache of the full network on local disk to validate data structures. With the Sync v1.1 updates, relays don't need all that disk I/O. What impact does that have on hosting setup and operating costs? Turns out the d...
Notes on Running a Full-Network atproto Relay (July 2024) | bryan newbold
Note: See updated post from May 2025 describing a newer, cheaper, easier to run relay implementation! These are some informal notes on setting up a full-network atproto Relay, using the bigsky relay software developed by Bluesky. This is the same software we run ourselves at https://bsky.network. T...

one interesting future challenge with atproto to me is that you can deploy an atmosphere app and its kind of 0 maintenance if the underlying network doesnt change dramatically, your marginal costs become 0. which means users have no real reason to pay you unless you keep adding stuff?
full-network space efficiency update: bad news: event though 84% of all repos are stale (no activity in 30 days), stale repos only make up 20% of the data in the network. moving them to cheap storage doesn't buy much. good news: the data in network is small?? like sub-1TB, minimal magic needed
@metaflame.dev gave a great explanation in this mini-thread of the advantages for the #atproto network in having multiple, independent relays operating
Metaflame
Redundancy, resilience, and possibly distance Importantly, once enough independent relays are active, they are likely to disincentivize malicious behavior for any one of them. Having multiple implementations (that is, different code) adds further resilience.
the critical thing that got me on board with atproto is relays incrementalize sync of the entire dataset, which eliminates polling when crawling the old web is currently being crushed under crawler load and I don't think it's going away, so I think atproto is the only way to save the open web
