What is Artificial Intelligence (AI)?

Artificial intelligence enables computer programs to mimic human intelligence. AI systems can process large amounts of data to learn patterns and relationships and make accurate and realistic predictions that improve over time. 

Organizations and practitioners build AI models that are specialized algorithms to perform real-world tasks such as image classification, object detection, and natural language processing. As a result, AI improves productivity, reduces human error, and facilitates data-driven decision-making for all stakeholders. Some prominent AI techniques include neural networks, convolutional neural networks, transformers, and diffusion models.

What is Blockchain?

Blockchain is a revolutionary framework offering a shared, decentralized – without a central authority, and immutable ledger for secure, transparent, and controlled exchange of data and resources among multiple entities. 

The blockchain concept was first realized in 2008 by an anonymous entity known as Satoshi Nakamoto, who introduced Bitcoin cryptocurrency in a famous research paper titled Bitcoin: A Peer-to-Peer Electronic Cash System. Today, blockchain reportedly powers over 23,000 cryptocurrencies globally.

Blockchain is based on the principles of encryption, decentralized architecture, smart contracts – programs stored on blockchain that trigger based on predefined conditions – and digital signatures. This ensures that data cannot be tampered with and restricted to authorized users only. Blockchain framework has far-reaching applications, from handling financial transactions to cryptocurrency, supply-chain management, and digital electorates. Some prominent examples of blockchain frameworks include Ethereum, Tezos, Stellar, and EOSIO.

The Synergy of AI and Blockchain

A merger between blockchain and AI frameworks can make more secure and transparent systems for enterprises. AI's real-time data analysis and decision-making capabilities expand blockchain’s authenticity, augmentation, and automation capabilities. Both technologies complement each other. For instance,

• Optimizing automation of supply chain processes by embedding AI in smart contracts.
• Addressing the challenges of AI ethics by ensuring the authenticity of data.
• Fostering a transparent data economy by providing actionable insights.
• Elevating the intelligence of blockchain networks by facilitating access to extensive data.
• Boosting security with intelligent threat detection in financial services.

According to Moody’s Investor Service Report 2023, the interaction of AI and blockchain can potentially transform financial markets by automating manual tasks and reducing operating costs in the next five years.

Major Opportunities for AI in Blockchain

AI and blockchain will converge to impact critical areas of our society. Below are some promising opportunities and use cases of blockchain and AI.

Fraud Detection

Despite various security measures, blockchain security is still a significant concern. Cyberattacks can potentially disrupt blockchain networks completely. Hence, AI is instrumental in elevating the security of blockchain frameworks. AI-powered fraud detection mechanisms can proactively detect and safeguard sensitive blockchain transactions from cyber threats.

AI and machine learning (ML) algorithms are capable of the following:

• Analyzing transaction patterns to detect fraudulent activities made by bots.
• Trigger alerts and events in real-time to help prepare against attacks.
• Enhance the security of smart contracts by blocking or minimizing smart contract-based cyberattacks, such as Reentrancy, overflow/underflow vulnerability, short address attack, and timestamp dependence.

AI-powered Smart Contracts

Smart contracts are self-fulfilling digital contracts with pre-established rules and governing principles, i.e., they automatically run actions or events when rules are met. AI can make these contracts more impactful by

• Optimizing smart contract code for reducing the cost of operating blockchain, such as Ethereum Gas.
• Improving the scalability of smart contracts using compression and parallelization.
• Analyzing & auditing smart contracts using classification and pattern recognition techniques.
• Integrating creative and cognitive capabilities in smart contracts.
• Facilitating testing and verification for smart contracts.

Moreover, AI automation can help save time and effort in handling complex blockchain workflows by reducing the need for human supervision.

AI-powered Analytics & Insights

AI enhances the capabilities of blockchain systems using data-driven insights. For instance, implementing AI in a blockchain-based supply chain can improve inventory operations, transparency, sustainability, etc. ML models can run analytics on secure and trusted blockchain transaction data to:

• Predict demand variations
• Shorten supply routes
• Improve order fulfillment
• Monitor the quality of products

By maintaining snapshots of all supply-chain operations on a blockchain ledger, stakeholders can gain real-time insights and improve the traceability of their supply chains.

Decentralized Data Storage & Processing

The decentralized framework of blockchain synchronizes well with the data-handling capabilities of AI. Distributed ML models like federated learning can train on datasets stored across multiple sources. Blockchain offers a perfect framework for analyzing complex and disconnected datasets using these ML models. It maintains the privacy and security of sensitive blockchain transaction data.

Major Challenges for AI in Blockchain

If we address the following prevalent challenges, the intersection of blockchain and AI can be more seamless and quick.

Scalability Issues

Scalability is a critical technical roadblock when integrating AI and blockchain technologies due to varying requirements, parameters, and limitations, such as processing speed, data handling, and resource consumption.

AI and ML models often require high-speed processing and low latency. They favor smooth data pipelines to deliver real-time insights for timely decision-making. Conversely, the blockchain framework has slower consensus mechanisms that are decentralized and strictly isolated in nature.

The following solutions can help address these challenges:

• Sharding – splitting the blockchain into smaller chunks for parallel processing and scalable usage beyond the restricted domain.
• Layering – introducing dedicated layers for specific functionalities, such as consensus mechanisms, storage partitioning, and AI-powered smart contracts. It enhances parallel processing and optimizes resource allocation.
• Sidechains – addressing the storage limitations of traditional blockchain networks by allowing smart device data to be securely stored in a separate database and mapping it to the sidechain transactions of the block.

Compatibility Issues

Making AI and blockchain work in synchronization requires ensuring compatibility factors. Addressing this issue demands highly optimized and effective data integration strategies and data-sharing models. Some of the vital approaches in this regard include:

• Bridging the gap of data format in AI (large amount, centralized) and blockchain (small amount, decentralized) to effectively interpret blockchain data.
• Using federated learning models with blockchain can help ensure trust and privacy while overseeing data and computation processes.

Legal & Regulatory Implications

Data privacy and protection are the primary concerns when exposing sensitive data regulated by a blockchain to AI and ML models. Regulation policies, such as GDPR, strictly force businesses to handle client data by ensuring:

• Consensual usage of data and information
• Data deletion, once processed
• Anonymization of sensitive personal or business data

The legal issues related to smart contracts are challenging. Therefore, it is mandatory to create contractual terms and conditions carefully.

The future of blockchain and AI are intertwined, given the rapid digital transformation across industries. Soon, we will witness many more advancements and opportunities, facilitating various business operations.
