Blockchain in accounting: The evolving role of accountants
March 30, 2026
Alexis Nicolaou, partner at Kreston ITH, argues that blockchain strengthens the relevance of accountants, as governance, oversight and professional judgement become increasingly critical in managing synchronised ledgers in a recent article for Business & Accountancy Daily.

Blockchain is often described as a technology that removes intermediaries and automates trust. In accounting, this prompts a common question: if transactions sit on an immutable, real-time ledger, are accountants still needed? The reality is the opposite. As systems become more automated and transparent, the need for professional judgement and governance increases. The profession is not disappearing; it is evolving.
Understanding blockchain in finance
Blockchain is a distributed digital ledger, where identical records are maintained across multiple network participants rather than a central database. Transactions are grouped, secured cryptographically, and linked in sequence, making them difficult to alter once validated.
In corporate environments, private or consortium blockchains are typically used, limiting access to approved participants. Applications include payment processing, intercompany accounting, asset tracking, smart contracts and document authentication.
With real-time, shared data, reconciliation efforts can be significantly reduced. However, while blockchain improves efficiency, it does not remove the need for interpretation, but rather it shifts where expertise is applied.
A shift from processing to oversight
Traditional accounting focuses on recording transactions and resolving discrepancies between separate ledgers. In a blockchain environment, where a single synchronised ledger is shared, the emphasis moves away from reconciliation towards system assurance.
Accountants are increasingly responsible for reviewing governance frameworks, assessing smart contract logic, ensuring compliance with tax and reporting rules, and monitoring internal controls. The role becomes more analytical and supervisory, focused on the reliability of systems rather than manual data entry.
Judgement, risk and governance remain essential
Blockchain’s immutability ensures that data cannot easily be changed after entry—but it does not guarantee accuracy at the point of input. Professional judgement remains essential. Digital assets still require correct classification, automated transactions must meet accounting standards, and financial data must reflect economic reality.
At the same time, blockchain introduces new risks, including coding errors in smart contracts, cybersecurity concerns, regulatory uncertainty and data privacy challenges. These issues directly affect financial reporting and compliance, placing accountants at the centre of governance, risk management and policy design.
Driving value through transformation
A mid-sized international logistics company illustrates the impact. After implementing a private blockchain for intercompany transactions and supplier invoices, reconciliation time fell by 65% and invoice errors by 40%. The month-end close shortened significantly, and audit processes became more efficient.
Importantly, the finance team did not reduce in size. Instead, roles evolved. Staff focused on monitoring systems, reviewing exceptions, and ensuring compliance, while dedicating more time to analysis, performance evaluation and risk management. Productivity improved, alongside the strategic contribution of the finance function.
Blockchain enhances transparency, but trust still depends on oversight, accountability and professional standards. Accountants play a central role in ensuring transactions are properly reported, controls are effective, and governance frameworks are robust.
Reinforcing trust in a transparent environment
As the profession shifts from verifying transactions to validating systems, new skills (particularly in technology and data) are required. Yet the core purpose remains unchanged: safeguarding the integrity of financial information.
Far from making accountants obsolete, blockchain elevates their role. In an increasingly automated environment, professionals who can interpret complex systems, manage risk and align innovation with financial reality are more valuable than ever.
