Consequences of Merging DIDs

[ChristopherA]

As any transaction can have multiple inputs, it is theoretically possible that two root DIDs could be merged into having single tip. I'm not sure if it is even possible to prevent this.

I don't know what the problems (or advantages) of this is.

My interpretation is that the theoretical transaction you are talking about would either:

1. Have no OP_RETURN. This means all the root DIDs that are inputs to the transaction would be considered revoked (could be a useful way of revoking multiple DIDs simultaneously!).
2. Have an OP_RETURN. In this case, the continuation DID document can only have one id. Therefore at most one of the root DIDs that are inputs to the transaction (the one where the id matches) would be resolvable.
