TEAtalks E1 | Triple Entry Accounting – Ian Grigg — The Foundational Paper

In this inaugural episode of TEAtalks, host Rhian Lewis sits down with Ian Grigg, the pioneering mind behind Triple Entry Accounting (TEA), to explore how this revolutionary framework challenges traditional double-entry bookkeeping. Ian explains how digitally signed receipts create a shared, tamper-proof transaction record, reducing fraud and enhancing financial transparency. They discuss the role of blockchain technology, whether TEA can exist outside of blockchains, and what it means for the future of accounting, auditing, and governance. If you’re new to Triple Entry Accounting, this conversation is your gateway to understanding why it could be one of the most important financial innovations of our time. The Guest Ian Grigg is the inventor of Triple Entry Accounting (TEA), a groundbreaking framework that enhances traditional double-entry bookkeeping by introducing digitally signed receipts as a shared, immutable transaction record. His work revolutionized financial cryptography by providing a tamper-proof, trust-minimized accounting system, making fraud detection and transparent auditing far more effective. Ian is also the creator of the Ricardian Contract, a fundamental innovation in cryptographically secure financial agreements. Since the 1990s, he has been at the forefront of digital finance, advising major blockchain and fintech projects, including EOS, Knabu, Mattereum, and R3. His research continues to shape the evolution of accounting, governance, and decentralized financial systems.
