Fast Bitcoin on BitShares

I would like to discuss the pros and cons of incorporating Fast Bitcoin as a UIA onto the BitShares platform in view of the first fork that has already occurred.

Motivation

"Consider the concept that a decentralized public currency should be platform independent and controlled by its owners, not its current hardware or software suppliers."

Benefits to Users

""The old Bitcoin Classic bridge is replaced by three: two patched footbridges and a superhighway.

• Bridge One is designed for miners to keep their hardware relevant.
• Bridge Two is designed for developers to keep their software relevant.
• Bridge Three is designed for users to give cheap, easy, fast and efficient service."

Overhead for witnesses
