It is, in fact, even easier to serve notice of a lawsuit to someone using blockchain technology than it is in real life, because you don't need a person's identity to do it.
Now, one of the fun ways that cryptocurrency wallets work is that anyone can drop anything in the wallet without the owner having to interact with or approve it - which makes it much easier to serve notice of a suit than, for instance, physically tracking someone down to hand them an envelope.
