@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.

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.

A Full-Network Relay for $34 a Month | bryan newbold
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...

I still wanna understand how applications can consume from multiple relays in parallel.. this was something @bad-example.com mentioned a while back and I'm still not sure I fully get it
