Explainable AI in blockchain transaction verification

6 min read

Thanks to blockchain technology, a wide range of industries can be equipped with decentralized and immutable ledger systems that increase transparency, security and performance. It can simplify supply chain management, efficiently track financial transactions, and securely transmit data across fragmented systems such as healthcare networks.

One of the key sectors where technology has made significant advances is the recording of financial transactions. However, with the increasing complexity of blockchain ecosystems and the need for compliance, auditing these transactions has become a challenge.

One possible solution is the use of Explainable Artificial Intelligence (XAI), which can process and analyze large amounts of data to help auditors and regulators gain insight into complex transaction histories and monitor compliance.

However, this raises ethical concerns as blockchains are designed to protect user anonymity.

Can XAI be implemented in an ethical way? What would this mean for the industry?

What is explainable artificial intelligence?

Explainable AI is a form of artificial intelligence (AI) and machine learning (ML) that involves developing models that explain the decisions they make. This allows users to understand how and why an algorithm makes decisions, which can lead to better solutions and increase confidence in the model.

It can also help identify errors and improve processes.

This is especially important in industries like healthcare and finance, where there is a need to ensure decisions are not based on incorrect data or bias.

Organizations must be transparent about their decisions to demonstrate their commitment to ethical and responsible data management.

When AI and ML are used in audit processes, audit evidence standards require auditors to provide appropriate and sufficient evidence to support their conclusions.

By integrating XAI into the audit process, auditors and regulators can gain deeper insight into complex transaction histories and ensure they comply with regulatory requirements.

The challenge of auditing blockchain transactions

Blockchain’s distributed ledger approach enables secure transactions and data tracking. Transactions are processed via a decentralized peer-to-peer network of nodes.

The data is stored cryptographically and shared in such a way that it cannot be manipulated or misused.

Traditional financial controls are relatively easy for auditors because they can quickly access the central records and databases they need to analyze and verify transactions.

However, because a blockchain is not overseen by a central authority, it can be difficult for auditors to access information.

Also, transactions processed over a blockchain can be very complex, involving multiple senders or recipients and the execution of smart contracts.

Blockchains provide transparency as the details of each transaction are stored publicly and are visible to any network user. This poses a challenge for auditors who need to control transactions while protecting sensitive data.

The lack of standardization in the blockchain industry for reporting and documentation also poses a challenge. Each blockchain can have its own unique protocol and data structure, making it difficult for auditors to access and analyze transaction data in a consistent manner.

How explainable AI can help with blockchain auditing

The introduction of explainable AI to blockchain technology can transform audit and compliance automation.

Blockchain technology provides a secure means of tracking transactions and data in an immutable and tamper-proof system.

XAI can help automate the review with efficiency and transparency, providing the following tools:

Processing complex patterns in transactions

ML algorithms can process large amounts of blockchain data in minutes. This is useful for complex transactions and records where trust is key.

It also reduces the time and effort required to conduct audits while improving detection and accuracy.

Explanation of the results

XAI can provide auditors with detailed explanations to help them understand why a transaction was determined to be non-compliant or non-compliant.

The auditors can validate the conclusions of the algorithm and ensure that no important or relevant aspects have been overlooked.

Fraud Detection and Prevention

XAI algorithms can analyze blockchain transactions to detect suspicious activity, discrepancies, and potential fraud. They can then explain how the model recognized them.

This creates a transparent and accountable approach to fraud detection that can help companies avoid financial losses and improve their compliance systems.

Error detection

XAI can detect potential system errors and warn users before damage occurs.

This can help reduce the risk of malicious attacks.

Sharing Audit Logs

Auditors can use blockchain technology to store and share audit trails in a secure environment. This ensures that they remain correct and that all changes can be traced.

The intersection of XAI and blockchain has potential in various industries. In healthcare, it can be used to securely exchange patient data and understand medical decisions.

In finance, it can help financial institutions track transactions and provide secure services to customers.

Ethical aspects: balancing transparency and anonymity

While implementing XAI to track blockchain transactions offers clear benefits, it raises important ethical questions, particularly around the core principles of blockchain, namely decentralization and anonymity.

Blockchain technology was developed to enable individuals to record transactions in a decentralized and immutable manner, protecting user privacy and reducing reliance on centralized third parties.

The introduction of AI to track and audit blockchain transactions could jeopardize these principles. AI could lead to increased surveillance and potentially violate users’ privacy rights.

Furthermore, centralized oversight of transactions through AI models would contradict the notion of decentralization that underlies blockchain technology.

To address these concerns, any implementation of AI must be approached with caution when auditing blockchain transactions, while maintaining a focus on upholding the core principles of the technology.

Finding a balance between transparency and anonymity is crucial. This is to ensure that AI-driven audits improve security and compliance without compromising the characteristics of blockchain systems that deviate from centralized systems.

The impact of AI-driven blockchain auditing

The adoption of XAI-based blockchain transaction audit solutions could have far-reaching implications for the industry:

  • Improved compliance: Implementing AI can streamline the verification process for compliance with regulations and standards.
  • Efficiency: By automating the analysis of large amounts of transactional data, auditors can focus on higher-value tasks, such as B. investigating complex cases and making strategic recommendations.
  • New applications: Developers could leverage the power of XAI and blockchain systems to create richer data visualizations and algorithms, provide new features and allow users to better understand the processes.
  • Standardization: The development of AI-powered audit tools could fuel the creation of standard frameworks for accounting and documentation across different blockchain platforms. This would facilitate consistent and accurate controls for the benefit of auditors and companies.
  • Trust and Acceptance: Implementing XAI in the field of auditing could increase trust among stakeholders, including regulators, businesses and consumers. The more the technology demonstrates its ability to detect and prevent fraudulent activity, the more it could boost the adoption of blockchain solutions.
  • Ethics-driven innovation: The development and deployment of AI tools that respect privacy and the principles of decentralization would be a positive example of how technology can be brought into line with ethical standards.


Auditing blockchain transactions is a clear challenge given the decentralized and complex nature of the technology. Implementing explainable AI can help address these difficulties by providing auditors and regulators with insights into complex datasets.

The ethical component needs to be carefully considered, but responsible integration of XAI into the review process could introduce a new layer of transparency and accountability to the blockchain ecosystem. This would save companies time and money while ensuring they are compliant with industry regulations.

XAI can play an important role in making the use of blockchain technology more trustworthy in critical transactions. There is also potential to combine XAI and blockchain technologies to drive innovation in the development of new applications.
