Abstract:

To verify that an organization-friendly blockchain system may suffer from forgery and collusion attacks, forgery and collusion attacks were theoretically carried out according to the phase sequence of an organization-friendly blockchain system. Then, the organization-friendly blockchain system was improved and based on the phase sequence forgery and collusion attacks were conducted. The results show that the attacker can obtain illegal transaction data from forgery and collusion attacks on the organization-friendly blockchain system. However, for the improved organization-friendly blockchain, the attacker’s forgery and collusion attacks cannot be completed. Therefore, the organization-friendly blockchain system may be subject to forgery and collusion attacks, but the improved organization-friendly blockchain system can prevent such attacks.
