According to Blockbits, on July 3, the Cryptoscope team discovered a flaw in the Ravencoin (RVN) blockchain and released an emergency update following a review by the development team. The vulnerability was reported to not affect or control existing RVN assets, although it could create additional RVNs. Due to this drawback, RVN's total revenue increased by 1.5% compared to the previous plan, and RVN was generated from the negative flow in the market, and operations such as restoration failed. Tokens generated by default are equivalent to mining by RVN miners for 44 days. To save the total amount of RVN from the initial plan of 21 billion, communities can do half of the excavation 44 days before the scheduled date.
