Thanks for the link, I was only aware of the Ring CT whitepaper. Still, he largely discredits all of the R&D that Bitshares has done which is rediculous and it is obvious he hasn't followed the Bitshares community closely (as it is obvious I haven't followed the Monero community closely.) Not only has Bitshares done a ton of research, but there are two words in R & D... Research and Development. Bitshares has done more development than both coins I mentioned (anonymint's vaporware and monero) combined.
