## 1 Introduction
In English language understanding benchmarks, in the SuperGLUE single-metric benchmark, the AI reached a score of 90.3 compared to a score of 89.8 for the human performance [15]. Blockchain technology is an emerging technology with wide-ranging application in the industry and services, namely transportation, aeronautics, and aerospace industries [16; 17; 18]. NASA and other space agencies have also expressed the intention to launch Blockchain-based distributed space missions [19] and internal operations. The Blockchain concept is becoming a valuable tool to record transactional data using a distributed ledger, leveraging efficient transactions validations in a verifiable permanent way and assuring transactional security [20]. The aviation industry is very sensitive to records; in fact, the record keeping is one of the main bases imposed by the regulators for the entire aviation ecosystem. Aviation would benefit largely from Blockchain-based record keeping, since it is impossible to forge, lose, or manipulate aviation records. Aircraft or engine lessons will specially benefit from this type of technology. When an aircraft changes owners, a very bureaucratic process is unleashed involving a few dozen persons and grounding the aircraft for weeks or months. With a Blockchain-based system, the processing time is reduced, optimizing all processes. When an aviation operator ceases its operations, it is frequent to see that theessors have difficulty retrieving all records from an aircraft or engine, which in some situations can lead to an entire recertification process, which can cost millions to achieve. If a Blockchain-based service was available, the airworthiness information is never lost, becoming accessible in those situations. In [21], the authors explained how the aviation world can improve in the area of aircrafts security with the implementation of Blockchain. The authors state that the Blockchain can help to secure the GPS satellite signal sent to the aircraft; in an event of GPS spoofing, the system can use the Blockchain-based digital ledger instead of the jammed GPS signal, which helps to secure the digital signal received by the aircraft. The Blockchain technology is a secure platform to register and make visible a series of transactional data called blocks that are linked using cryptography, which asserts an immutable, change-resistant timeline of events and its associated data that brings transparency, immutability, security, traceability, and interoperability to the stored data [18, 22]. The Blockchain is open and distributed over different involved parties called ledgers. The ledgers work over the Blockchain platform and are composed of several parties that record and certify transactions, which are recorded in a verifiable and permanent way [23]. An integrated Blockchain platform, based on common regulated principles, can be used to register and assert the historic data of network activity, AI decision making, HSS interconnection activity, and others [24, 25, 26]. Half (50%) of the companies in life science, consumer products, tech, healthcare, and media have already deployed Blockchain solutions, being $1.4 billion invested in new projects between 2014 and 2017 [27]. The deployment of a Blockchain ecosystem in the proposed Large Geographical Area Aerial Surveillance Systems Data Network Infrastructure will guarantee the various HSS, which is a verifiable activity of its operations and managing services. The paper is structured as follows. Section 2 presents the proposed Data Network Infrastructure for Heterogeneous Smart Solutions. Section 3 presents an overview of the proposed Edge AI infrastructure to automate the operation and maintenance of the Data Network Infrastructure services. An Edge AI service operation example is presented to give the reader a view over several Edge AI Agents cooperation. To give some technology context to the reader, several hardware and software solutions to support AI services are presented. Section 4 outlines the conclusion.
