A Hungarian cryptocurrency developer named Zoltan Szabo (aka Borzalom) is the lead developer of XTRABYTES. Like many others investors, Borzalom was a victim of the Bitmox scam. After the scam, he decided to create a real community for Bitmox victims. And ultimately, he decided to repair the source code and rebuild the node network. Additional details about how XBY was created by Borzalom can be found here. I encourage you to read it in order to understand this man’s passion for the project. And if you have time, I strongly recommend watching this video created by CCRevolution (the other XBY co-founder, along with Borzalom). Dave (CCRevolution) speaks about how he came to know Borzalom and how they came together to create XBY out of the Bitmox ashes. It’s quite a touching story.
In addition to Borzalom, there are other developers who are currently working on the core XBY blockchain. Another small team is working hard on the X-CITE client, the front-end application designed to provide easy access to XTRABYTES’ core functionality. And yet another team has been created to ensure that the UI (user interface) and UX (user experience) compliment each other (both must be taken into account in order to ensure functionality across desktop and mobile versions). Finally, several groups have been created to produce the initial modules expected to run on the XBY platform: X-VAULT (data storage), X-CHAT (decentralized messaging), X-CHANGE (a decentralized crypto exchange), as well as others that have not been announced. Further details about the team behind XTRABYTES can be found here.
Anyone can go back through the history of the project and vet the developers themeselves here:
