Proof of Existence with Broadcast


We could do that with a signed account at blockscan but this would mean a centralized time stamping authority…

And in reality I am not sure how useful would such a service be for Counterparty ??

It’s already possible to post a hash of a file as a broadcast, and to verify it on Blockscan or the API.

Also, another neat feature in Counterwallet would be to write arbitrary messages that would then be Broadcast. Or a plugin to allow such features. For some reason I really want an “I was here” button that I can press and let humanity/posterity know that I was indeed here.

I’m really confused by your request. This is already possible. And in counterpartyd the text can be like 1K+ in size, which will be added to Counterwallet soon.


I don’t see an option in Counterwallet to Broadcast arbitrary messages yet? (Oh, I see you addressed that). All I was talking about was having plugins for Counterwallet that might allow for additional functionality - like Proof-of-Existence style functionality or buttons to embed comments like “I was here” or “I love X” in the Bitcoin Blockchain.
