ring signatures will never work 100%.

This seems to be the case as the 8x size of ring signature blockchain compared to bitcoin is a bloat that is impossible to overcome. Monero will just never be able to scale up to any meaningful number of users.

Happy to report that Darkcoin has figured a way to improve security even further but without the added bloat that ring signatures would cause:

RC3 Progress Report

I've had some substantial progress on DarkSend and have figured out how to make our existing system as secure as ring signatures. Vastly improved security, no bloat (from the ring signatures) and without actually having to trust new cryptography (it hasn't been extensively tested like what DarkSend uses) . So I think it'll give us a HUGE advantage in the coming months. More to come soon, I'm going to start implementing this tomorrow. Grin
