Blockchain in Finance — What It Means for Accountants and Finance Professionals
Blockchain explained for finance and accounting professionals: how blockchain works, its applications in finance (smart contracts, DeFi, tokenisation), and what accountants need to know about crypto and blockchain.
Blockchain in Finance — Overview
Blockchain technology — the distributed ledger that underpins Bitcoin and thousands of other applications — is increasingly relevant for finance and accounting professionals. While blockchain's most visible application is cryptocurrency, its implications for accounting, audit, supply chain finance, and financial markets are significant.
What is a Blockchain?
A blockchain is a distributed, decentralised ledger — a database shared across a network of computers, where transactions are recorded in blocks, cryptographically linked, and immutable (cannot be altered once confirmed). There is no central authority controlling the ledger.
Key properties relevant for finance:
- Immutability: Once recorded, transactions cannot be changed — creating a permanent audit trail
- Transparency: On public blockchains, all transactions are visible to participants
- Decentralisation: No single point of failure or control
- Programmability: Smart contracts — self-executing code that automatically enforces contract terms when conditions are met
Blockchain Applications in Finance
Cross-Border Payments and Remittances
Traditional international wire transfers take 2–5 days and cost 3–7%. Blockchain-based payment networks (Ripple/XRP, Stellar) enable near-instant, low-cost cross-border transfers. For India — one of the world's largest remittance-receiving countries (~$100 billion/year) — this is significant.
Smart Contracts in Corporate Finance
Self-executing contracts that automatically release payments when predefined conditions are met — no intermediary required. Applications in trade finance (letter of credit automation), derivatives settlement, and supply chain finance.
Tokenisation of Assets
Real-world assets (real estate, bonds, private equity, art) can be represented as digital tokens on a blockchain. SEBI has been exploring tokenisation of securities; RBI is developing a wholesale CBDC for interbank settlement.
Decentralised Finance (DeFi)
DeFi applications provide lending, borrowing, and trading services through smart contracts — without banks or intermediaries. While largely unregulated, DeFi is growing rapidly and regulators globally are developing frameworks.
Audit and Accounting
Blockchain creates an immutable transaction record — potentially enabling continuous audit rather than periodic sampling. Big 4 firms are investing in blockchain audit tools that can query ledgers directly. For accounting standards, ICAI and IASB are developing guidance on cryptocurrency accounting.
Accounting for Cryptocurrency
There is currently no specific IFRS standard for cryptocurrency. Under current IFRS:
- Cryptocurrencies are generally treated as intangible assets (IAS 38) — measured at cost less impairment (unless held for sale, when IAS 2 inventories may apply)
- IASB has a project on crypto assets in progress
- India: RBI has no legal tender status for crypto; Indian companies holding crypto treat it under applicable AS/Ind AS guidance
What Finance Professionals Need to Do
You do not need to be a blockchain developer — but you should understand the technology well enough to assess its implications for the entities you audit or advise. ACCA's continued professional development content covers emerging technology for finance professionals.
