Abstract: A method may include obtaining various votes for a blockchain transaction from various blockchain nodes. The method may further include determining various weighted votes using the votes and respective cybersecurity states of the blockchain nodes. The respective cybersecurity states may correspond to whether a predetermined security vulnerability is associated with the blockchain nodes. The respective cybersecurity states may be dynamic values that are updated based on changes among predetermined security vulnerabilities. The method may further include determining whether to validate the blockchain transaction based on the weighted votes.

Abstract: A system, a method, and a computer program for remediating a cyberattack risk for a computing resource located at a node in a computer network having a plurality of nodes. The solution includes receiving vulnerability score data that has a severity level for a vulnerability in the computing resource at the node, receiving a number of installations value (NCRi) that indicates a number of instances the computing resource is included in the plurality of nodes, determining a percentile of occurrence value (POCRi) for the computing resource based on the number of installations value (NCRi), applying a severity adjustment matrix to the severity level to determine a true severity level for the vulnerability in the computing resource, reprioritized the vulnerability in the computing resource based on the true severity level, and mitigating the cyberattack risk for the computing resource based on the true severity level.
