Hello,
Does anyone know where I can find an off-the-shelf wallet application that can create a hash of a document and store it on the bitshares blockchain?
Specifically, we are researching Blockchain opportunities for professional engineering Society and want to eventually develop a branded registry for securing engineering works.
Thanks
It can easily be written as a Python app, encode the hash as a series of transactions similar to how Omni or Counterparty does it. Does anyone know the Bitshares API well enough to write this app?

@xeroc - but he's on vacation ISTR
What about two separate programs; 1. to create the hash and the other, a simple wallet, to load the key? Does this make sense?
Thanks
I guess you could do something like that with Custom Operations.
Good idea - I think
@roadscape has some experience in that direction?
Great idea. PM'ed you some thoughts.
do it
Thanks for the comments. Indeed we want to "do it".
"Poor Man's Patent" is just a way to describe the functionality that we need in a simple way. Actually, this application would reside behind the National Society of Professional Engineers membership curtain. Instead of "inventions", they would archive their "stamped" works upon an appropriate ontology on a secure server and the hash of those documents on a blockchain. Those parts would come later, we just need to prove one step at a time. No budget now, that's why I need off-the-shelf. If demonstrable, they would fund, etc.
Can anyone help mash something together?
Are you looking for a web app that private/securely stores PDF files but publishes their hashes publicly?
That sounds promising. Does it exist? This seems like a fairly straight forward request - like the first thing that blockchain would have been used for. So an application should exist, true?

The "False" flag in "sign_builder_transaction" needs to be set to True if you want to broadcast your transaction

Try out Alexandria (http://alexandria.media/#/media/type/book) and start getting familiar with IPFS (http://ipfs.io)...
There are several of these cool services:

OK, excellent... Blocksign is the perfect demo for this tech. Thank you deeply.
I wouldn't mind competing with Blocksign, or otherwise compelling them to apply their methodology to the Bitshares blockchain.
