UCL Open Seminars: REA, Triple-Entry Accounting and Blockchain: Converging Paths to Shared Ledger Systems

REA, Triple-Entry Accounting and Blockchain: Converging Paths to Shared Ledger Systems


In recent years, the concept of shared ledger systems offering a single source of truth has begun to put traditional bookkeeping into question. To date, its historical development remains unclear and under-researched. This paper conducts a genealogical analysis of shared ledger systems from their early forms such as Resource-Event-Agent (REA) accounting and triple-entry accounting (TEA) to their present incarnation in blockchain. We show how accounting frameworks developed between the 1980s and the early 2000s constitute the historical roots of TEA and have impacted much-discussed blockchain applications of today. As such, we duly acknowledge the influence of each individual contributing to this development, correct common misconceptions and map out how the paths of REA, TEA and blockchain converge in the realm of shared ledger systems.

During this proving time, we recognise the difficulties and sense of isolation that many are experiencing. While many events and conferences have been cancelled worldwide, UCL CBT believes that now more than ever it is essential to stay focused and keep pushing the boundaries of knowledge with a sense of solidarity and altruism.

In this spirit, we launched a massive series of Online Open Seminars. These will be free access seminars promoted by the UCL CBT to give voice to our Research and Industry community. Find below the schedule here.
