I would like to send transactions with messages as described in the wiki. In Transaction with slightly changed script is never relayed, someone answered that non-standard transactions are not relaid by the client. I was wondering if this will affect this type of transactions.
Also, I would like to know if there is a source code that implement this functionality. I need to send small data (SHA256) as a digital signature that can be view by all the peers in the network and is associated to this specific transaction.
Thank you very much and your help is very appreciated
