Zcoin uses the RSA-2048 number from the RSA factoring challenge. The computer’s hard drive which generated the factors were destroyed over 25 years ago. No factoring solution to the RSA-2048 number has been found for the past 25 years, and it is unlikely to be factored in the next several decades. In the long term, Zcoin would eventually shift to a different cryptographic scheme for its setup parameters or move to a trustless setup entirely.
