“Some of the biggest digital currency exchanges have been hacked and the rest are looking over their shoulders” says Banx Capital CEO and Founder Mark Lyford. “BitShares is offering their SmartChain as a safe, level playing field for use by the whole industry. It can serve as backbone network to all the exchanges as a way for them to trade with and against each other. With shared order books we will have deeper markets, tighter spreads, and greater liquidity. And since our customers keep their own keys while trading on this network, combined with hierarchical multi-sig capabilities – we can’t get hacked, and our customers can’t get hacked.”
