Proof of Existence on MultiChain

Question

Hi,

How can I create a PoE in MultiChain?

In Bitcoin some people use OP_RETURN and add the hash that represents the file.

In MultiChain what is the efficient way to achieve it?

Thanks.

Your simplest method is to use streams. You can put the hash in either the key of the data of the stream items, depending on whether you want to look items up by hash, or by some other identifier.
