The "Big Four" audit firms—Deloitte, EY, KPMG, and PwC—recently joined a pilot program with 20 Taiwanese banks to test blockchain technology for financial audits. This move validates predictions about blockchain's transformative role in external audits.
The Intersection of Audits and Blockchain
External audits involve examining an organization’s financial records to verify accuracy under established standards like IFRS or GAAP. What changes—and what remains unchanged—with blockchain adoption?
Transformative Impacts of Blockchain
Streamlined Verification:
Blockchain’s distributed ledger ensures transparency, immutability, and real-time access to transactions. Auditors can skip traditional external confirmations, saving time and resources.- Example: Cross-checking liabilities between companies becomes instantaneous via public ledgers.
- Enhanced Transparency:
Bank detail reviews (e.g., loans, guarantees) benefit from always-accessible data, reducing manual scrutiny.
Russell Guthrie, CFO of IFAC, notes:
"Blockchain and AI are raising industry standards, demanding new skills."
Persistent Challenges
- Subjective Judgments:
Areas like fair-value asset assessments or revenue recognition still require auditor expertise, even with blockchain adoption. - Gradual Adoption:
Complex accounting estimates may lag in blockchain integration due to inherent uncertainties.
How the Big Four Are Embracing Blockchain
| Firm | Initiative |

Pierre-Edouard Wahl (PwC Switzerland):
"We audit crypto holdings and advise on legal/tax implications—though ‘audit’ isn’t always the right term."
The Future of Audits
Blockchain will redefine external audits by:
- Prioritizing IT controls for public ledgers.
- Reducing redundant procedures while maintaining judgment calls on estimates.
Marcel Stalder (EY Switzerland) emphasizes:
"Blockchain’s business revolution requires universal participation."
