What Accountants Need to Know about Blockchain*

Reports by professional organizations (e.g., AICPA, CPA Canada, and ICAEW) argue that blockchain adoption is likely to reduce the need for record‐keeping tasks and shift the accounting focus to higher‐level activities. To evaluate such expectations and form their own opinions, accounting professionals need to understand the way blockchain works in a business setting. The primary objective of this article is to provide the reader with the foundational knowledge needed to better understand reports such as those suggesting that blockchain will change the way auditors execute their engagements and generate new assurance opportunities for configuring policies in blockchain networks. Building on evidence indicating that the most promising use cases are from the logistics industry, we describe a blockchain implementation in a supply chain setting. Using a scaffolding approach, we start with a supply chain and describe how blockchain is implemented in one of its segments, before we show how a complete transaction is recorded on the ledger.
