Abstract— With the rapid evolution of artificial intelligence
(AI) in smart cities, secure and efficient data-sharing
mechanisms to encode privacy, integrity, and accessibility are
required. As a natural result of a centralized data-sharing
framework, they remain vulnerable to security issues,
unauthorized access, and most importantly, single-point-of-
failure. Data confidentiality does not concern the layer
blockchain technology; it offers better trust and security among
stakeholders due to its decentralized and tamper-proof data
manager. The outline of how block chain can resolve AI-based
smart city data coming from diverse citizen-based sensors is
discussed; consensus mechanisms, urgent access, multi-
signature encryption is explored. Blockchain improves data
transparency, reduces fraud, and ensures compliance with data
privacy regulations by leveraging smart contracts and
distributed ledger technology. In addition, the study addresses
challenges related to the scalability which is a computational
overhead issue and regulatory constraints that blockchain can
face, and some solutions that could help the adoption of multiple
stakeholders in urban infrastructures such as blockchain. The
results show how a secure sharing of information via blockchain
can drastically improve smart cities powered by AI ensuring
their resiliency and efficiency toward sustainable intelligenurban environments.
