1 INTRODUCTION

Blockchain and Artificial Intelligence (AI), as two

most advanced technology, each play an important

role in their own field. Blockchain is an innovative

technology that makes it possible to create

dependable applications without requiring peer trust

(Mattos et.al, 2020). Blockchain is implemented

through a decentralized distributed network and

encryption technology, while AI technology achieves

automated decision-making intelligent functions

through data analysis and machine-learning. With

various AI technologies, blockchain implementation

can be aided or augmented. It is believed that the

combination of AI and blockchain can create

countless possibilities in the future (Marwala and

Xing, 2018). This combination not only improves

data security and promotes the development of smart

contracts, but also promotes the realization of

decentralised decision-making, which has significant

impact in many fields such as social governance and

enterprise management.

The combination of blockchain and AI has

already been widely used and led to many innovative

applications and create synergies in a variety of fields.

In healthcare, the accuracy of early sickness detection

might be significantly improved by potent AI and

computer technologies. However, security is still a

concern because of the centralized nature of the

existing system. Therefore, safety can be offered via

blockchains, a relatively new and developing

technology (Kumar et.al, 2019; Thomason et.al, 2018;

Clauson et.al, 2018; Sylim et.al, 2018). In this case,

A decentralized access control strategy built on

blockchain technology and artificial intelligence is

suggested (Rana et.al, 2022). Furthermore, utilizing

the most recent cutting-edge techniques and

applications, a blockchain-enabled Intelligent

Internet of Things (IoT) Architecture with AI was

present, which offers an efficient way to combine

blockchain technology with AI in the area of IoT

(Singh et.al, 2020). In data management, blockchain

2.2 Core Technologies

2.2.1 Blockchain Technology

Blockchain is a decentralized technology that

maintains a shared database through multiple network

nodes to ensure data transparency, security, and

immutability. blocks, chains, Cryptographic

algorithms, distributed ledgers, and consensus

techniques, are core constituent parts. These blocks

are sets of data that are connected chronologically to

form a chain, that is where the blockchain name

comes from. Every block is unique in its hash value,

a fixed-length value calculated from the input data via

a hash function. Every new block contains the hash of

the preceding block, which ensures data integrity and

tamper resistance. With distributed ledgers, single

points of failure are eliminated and greater reliability

and security are achieved by ensuring that every node

has the same copy of the ledger, updated

concurrently. Transaction validation criteria are

established using consensus techniques like Proof of

Work (PoW) and Proof of Stake (PoS), which

guarantee node agreement on the legitimacy of

transactions. Public-key cryptography securely

verifies transactions, while cryptographic algorithms

such as Secure Hash Algorithm (SHA)-256 offer data

security and anonymity. These tenets allow

blockchain to provide trusted transaction records and

decentralized data management, which are highly

valued in supply chain management, smart contracts,

and finance.

2.2.2 AI Technology

AI is probably better known than blockchain. As a

branch of computer science, it aims to mimic human

thinking by creating complex algorithms that perform

difficult tasks that previously required human

intelligence to complete (Bekbolatova et.al, 2024).

For example, AI can perform tasks like learning,

reasoning, and understanding natural language. Key

concepts in AI include machine learning, neural

networks, natural language processing (NLP), and

computer vision. Through machine learning,

computers may learn from data without the need for

explicit programming, finding patterns that help them

anticipate future events. Typical techniques include

reinforcement learning, which maximizes decision-

making through trial and error, supervised learning,

which makes use of labeled data, and unsupervised

learning, which uncovers structure in unlabeled data.

Deep learning applies neural networks similar to the

structure of the human brain to process more complex

data, including speech and images. Neural networks

are made up of interconnected nodes, or neurons. By

utilizing statistical techniques and machine learning,

NLP gives AI the power to understand, process and

react nearly as well as humans. This is helpful for

sentiment analysis, machine translation, and

detection of speech. Machines can now understand

pictures and videos thanks to computer vision, which

has applications in everything from autonomous

driving to facial recognition. In summary, AI models

human intelligence across various domains,

transforming industries and unlocking new potential

as technology advances.

2.2.3 Combined Application

The combination of AI and blockchain technology

offers significant potential across various domains,

including the IoT, healthcare, and financial data

management. In the area of IoT, Blockchain provides

data integrity and security through unique device

identifiers and tamper-proof records, while AI

improves device operation and maintenance by

analyzing massive amounts of data. In the medical

field, this collaboration produces safe digital health

records that protect patient confidentiality and

identity while permitting safe data exchange. For

individualized diagnosis and treatment suggestions,

AI evaluates vast amounts of health data, and

blockchain prevents unwanted access. Moreover,

Blockchain strengthens the reliability of data by

offering transparent, unchangeable transaction

records for data management. AI improves prediction

accuracy by using this data for market trend research

and real-time risk assessment. Furthermore, the smart

contracts of blockchains automate the execution of

transactions, enhancing security and efficiency. In

conclusion, the combination of AI and blockchain is

revolutionizing various domains by improving data

security, effective management, and intelligent

applications.

ledger technology in healthcare has several benefits,

as shown in Figure 3. It makes it easier to develop

"smart" healthcare professionals who can create

individualized treatment programs. Because the

technology offers more secure and comprehensive

health records, interoperability is improved. Smart

contracts prevent fraudulent insurance claims,

automatically manage rights, and enhance data

coordination. By using distinct addresses and

cryptographic security, it guarantees correctness in

provider directories. Furthermore, blockchain makes

it easier to obtain thorough medical records, which

results in a less intrusive and more user-friendly

procedure. Overall, it facilitates a dynamic

relationship between clients and insurers by

3.2 Discussion

The integration of AI and Blockchain shows great

potential, especially in the IoT and healthcare area.

This combination can enhance data security and

analytics while addressing some of the limitations

present in traditional systems. As the analysis above,

blockchain offers a decentralized, safe method of data

storage, while AI can process and analyze data

gathered from multiple devices in real time. IoT

devices can share and validate data more effectively,

which improves decision-making, by fusing

blockchain technology with AI algorithms. For

instance, blockchain technology enables smart home

devices to protect user privacy and data security

against unauthorized access by leveraging AI to

analyze user behavior. This combination also leads to

improved patient health data management in the

healthcare industry. Blockchain protects the

confidentiality and transparency of this sensitive data,

while AI analyses a patient's medical history to give

personalized treatment options. Smart contracts can

automate patient-provider interactions, eliminating

the need for middlemen and boosting productivity.

However, this combination also faces many

challenges. First, data privacy and security remain a

major concern. Although blockchain provides

security, how to achieve effective data sharing while

ensuring data privacy still needs to be explored.

Second, the complexity of the technology may lead to

high implementation costs, limiting its popularity.

Overall, The outlook for the future is still optimistic.

As technology advances, BlockIoTintelligence is

expected to play an increasingly important role in

improving efficiency, reducing expense and

enhancing user experience. Solutions to these

challenges include developing smarter algorithms,

optimising blockchain technology to increase its

processing speed, and establishing industry standards

to facilitate interoperability between different

systems.
