@3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d @de7ecd1e2976a6adb2ffa5f4db81a7d812c8bb6698aa00dcf1e76adb55efd645 The original object has its own globally unique ID. Eg event.id on Nostr, object.id in ActivityPub.

So you expose that ID to the bridged network, and implementations can combine objects that share the same proxy ID.

For AP objects bridged to Nostr, it could look like:

["proxy", "activitypub", "https://gleasonator.com/objects/123"]

Clients could combine events with the same proxy ID.

There are obviously problems with trust (among other issues). But I think it will be necessary to solve this problem.
