 Cryptaur Blockchain is completely our own development. The project was available on github for over a year, but then this information, together with the blockchain explorer data, was used by cybercriminals to carry out hacker attacks. In order to increase the security of our system, both the source code and the explorer were hidden from public access. Currently we are working with external auditors reviewing the security of the system we have developed. Upon completion of this work, the source code will be open again.
