xCore has been working with the code for over a year, he has the code and skills to put out an updated wallet and keep the chain running just fine. Developing zeroledger may be a different story. He also was going to put out the android and iphone wallets once zeroledger (thin client) was done. It probably is done, but don't know if JC left it for xCore to work on. And to put anyone's mind at ease, xCore is WELL known in IRC rooms as he made most of the tip bots, rain bots, and pricing bots before Vcash. He has nothing but the communities best interest and continuation of the coin at heart, and JC gave him access to a lot of the code which he was part developer. He worked for free, for the love of the project and knowledge, and even JC scolded him and treated him badly.  xCore is a person with good character, complete opposite of JC.
