An internal auditor’s guide to auditing blockchain

Blockchain is a new technology that can revolutionize how businesses operate. As an internal auditor, it’s essential to understand how blockchain works and how it can be used in your organization.

In this blog post, auditors like Farahat and co. will provide an overview of blockchain and discuss some of the key issues that internal auditors should consider when auditing blockchain-based systems.

What is blockchain, and why do we need to audit it?

Blockchain is a digital ledger of transactions. When a transaction occurs, it is recorded on a “block” of data. The block is then added to the chain of existing blocks, creating an immutable transaction record. 

This record can be used to verify the authenticity of future transactions. Blockchain technology has the potential to revolutionize many industries by making transactions more secure and transparent.

 For example, in the banking industry, blockchain could streamline the process of clearing and settling trades. Banks no longer need to rely on centralized clearinghouses to verify transactions by using blockchain. Instead, they could rely on the blockchain’s decentralized ledger. This would make transactions more efficient and reduce the risk of fraud. 

 How does blockchain work?

A blockchain is a distributed database that allows for secure, transparent, and tamper-proof data management. each transaction made on the blockchain is securely encoded with a digital signature that verifies its authenticity. 

This signature is then stored on a network of computers, known as nodes, which helps to ensure that the transaction cannot be altered or deleted. Once a transaction has been recorded on the blockchain, it cannot be changed, making it an immutable record of information. 

In addition, because each transaction is linked to all previous transactions, it is impossible to delete or tamper with any part of the blockchain without invalidating the entire dataset. As a result, blockchain technology offers a unique way to store and manage data that is both secure and transparent.

The benefits of internal auditing of blockchain systems

Internal auditing of blockchain systems is essential for the continued efficacy of the system. By verifying and validating transactions, internal auditors can help ensure that the system runs smoothly and efficiently. 

In addition, keeping track of changes to the system can help identify potential vulnerabilities and prevent them from being exploited. Internal auditing is vital to any blockchain system and should be conducted regularly.

Key components of a successful blockchain audit process

A blockchain security audit is a process of reviewing and analysis of a blockchain protocol or platform. It is conducted by an independent third party to assess the blockchain’s security, accuracy, and compliance with agreed-upon standards. The audit process generally includes four key components: technical analysis, risk assessment, due diligence, and recommendations. 

The technical analysis assesses the security of the blockchain platform or protocol from a computer science perspective. This audit component evaluates the cryptographic algorithms, reviews the code for vulnerabilities, and tests the platform for scalability and performance. 

Risk assessment looks at the potential risks associated with using the blockchain platform or protocol. This component of the audit assesses legal risks, reputational risks, financial risks, and operational risks. 

Due diligence is conducted in order to verify that the blockchain project is adhering to agreed-upon standards. This audit component involves reviewing documentation, speaking with project members, and assessing compliance with relevant regulations. 

Finally, recommendations are provided based on the findings of the audit. These recommendations may include changes to improve the security of the blockchain platform or protocol, suggestions for mitigating identified risks, or best practices for complying with relevant regulations.

The different types of Internal audits that can be conducted on a blockchain system

Different types of internal audits can be conducted on a blockchain system, including compliance, operational, and financial audits. Compliance audits assess whether the system is compliant with applicable laws and regulations. Operational audits assess the efficiency and effectiveness of the system’s operations. 

Financial audits assess the accuracy of the system’s financial statements. Each type of audit has its unique procedures and techniques. However, all internal audits share one common goal: ensuring that the blockchain system operates effectively and efficiently. 

By conducting a detailed review of the system’s operations, compliance with applicable laws and regulations, and financial accuracy.

Tips for auditing a blockchain network effectively.

Any business that deals with digital transactions should be aware of blockchain technology and how it can be used to secure these transactions. Here are some tips for auditing a blockchain network effectively:

  • Hire a reputable firm to conduct the audit.
  • Make sure the firm has experience auditing blockchain networks.
  • Review the firm’s methodology and understand how it will test the network’s security.
  • Set clear objectives for the audit and provide the firm with all relevant information about the network.
  • Ask for a report outlining the results of the audit, and make sure to review it carefully.

By following these tips, businesses can ensure that their blockchain network is audited effectively and that any risks are identified and addressed.


The internal auditor’s guide to auditing blockchain is an important tool for understanding how blockchain works and how it can be used to improve the efficiency of your organization. Auditors should use this guide to assess the risks associated with implementing blockchain technology.
