This paper redefines cybersecurity as a shared shield—a distributed decentralized system driven by blockchain technology whereby businesses unite against invisible enemies. We combine the accuracy of artificial intelligence with the unbreakable ledger of the blockchain to build a real-time defense network. Hybrid consensus (PoA + Reputation-Based) verifies risks so guaranteeing credibility without invading personal space. While federated artificial intelligence models—Bayesian Trust, logistic regression, GMM—detect anomalies and prioritize risks—Smart contracts work as digital guardians, auto-deploying countermeasures like firewall updates. There is a change in more spheres than merely technology here. Eliminating barriers to openness helps companies to fight together in relentless alliances instead of working alone. Turning vulnerability into awareness will help us to create a safer digital future Supplementary Material File (blockchain application_may.docx) Download 445.88 KB Information & Authors Information Version history V1 Version 1 30 May 2025 Copyright This work is licensed under a Non Exclusive No Reuse License.
