been thinking about this. I think the best form factor for a PDS is bsky.social + a phone app that holds your PLC keys and also performs automatically repo backups. so you can just adversarially migrate with one button press while still using a big hosting provider for uptime, for free

I made a PoC for the key holding part: github.com/mozzius/deme... and @retr0.id is working on adversarial migration tooling for goat. it’s all coming together!

anyway, point is the great strength of this architecture is not in its “active” state, but in its “passive” state - you can just show up with your repo somewhere else, without asking permission. so just use bsky.social right up until the point you don’t want to

get your key sovereignty here

What about backing up the repo? Obviously some repos will be large, but could they be backed up to iCloud?

even big repos are only on the order of megabytes. I think the real issue would be syncing the blobs

What are the options for background tasks on iOS? Even a daily automatic backup would be a good start, especially if I can trigger a manual sync in the app (I.e., immediately before migrating or taking some action I may want to revert).
