Storing blob for multisignature

Question

Hello,

I have some data that needs to be signed by 2 nodes before being accessible to a third node for further work.

I do something like this: createrawsendfrom 489fDHcC56ZZnLfQZ41PkNEz1i8ZABy6aqWNGQ '{}' '[{"for":"stream9","key":"key1","data":"48656c6c6f2066726f6d206d756c746973696721"}]' sign

From what I have learned the resulting blob is not stored in the blockchain because it is an uncomplete transaction so I store it in another stream. I was wondering if there was another way of sharing that blob between the 2 nodes. 

Could somebody please tell me if there is another way to do this or not ?

 

Best regards.

Right now the only way to transfer information directly between nodes is via stream items. The next alpha of MultiChain 2.0 will implement off-chain stream items, whereby only a hash of the data goes into the stream, and the data itself is delivered off-chain directly between the nodes (or via an intermediary).
