Hi Thomas, My problem is that this seems to lacks a vision. > Are you aware of my proposal for network assurance contracts? There is a discussion here: https://www.mail-archive.com/bitcoin-development@lists.sourceforge.net/msg07552.html But I agree with Gavin that attempting to plan for 20 years from now is ambitious at best. Bitcoin might not even exist 20 years from now, or might be an abandoned backwater a la USENET.
