I see a lot of transactions which have more than one recipient address.
Edit #1: I just saw a tag call multi-sig-transactions. It is obviously what I am asking for.
I did not see in the clients before. How come that there are so many of them?
Edit #2: After reading little bit about multi-sig-transactions I am not really sure that these transactions are these multi-sigs. This opinion is not based on real knowledge but just on such a great number of these transactions in every block.
