Probinex (PBX) v1 was the initial version of the Probinex cryptocurrency, which underwent significant changes following a sophisticated hack in October 2022. The incident led to the compromise of a portion of PBX tokens and initiated Operation Phoenix, resulting in the creation of a new, enhanced PBX token. This new token featured improved security measures and was audited by CertiK. The Probinex team's effective crisis management and strong community support were pivotal in overcoming this challenge and advancing the project's goals in the cryptocurrency and blockchain domain.
