Reimagining Triple-Entry Accounting: A Blockchain System for Confidential Transaction Verification

This thesis presents a blockchain-based accounting system that prioritizes trans actional privacy, modular design, and automated verification. It does so without relying on cryptocurrencies or public transparency. Unlike most blockchain-based accounting platforms, which apply blockchain principles to accounting, this system inverts the model. The result is a centralized, permissioned network built on Hyper ledger Fabric that uses Chaincode-as-a-Service, private data collections, and event driven listener services.

The system enables organizations to verify transactions on a per-transaction basis. At the same time, it maintains the confidentiality of their financial records. Chaincode functions emit events that trigger automated cross-organization workflows. These allow for confirmable but private triple-entry accounting with little user input. Unlike prior work in the field, this implementation is tailored for in ternal audits and small- to medium-sized enterprises, specifically ones with a single accountant.

The system was tested in a local, multi-organization environment. It demon strated correct behavior across a range of transaction workflows. The system resists misuse, supports dynamic onboarding, and has the ability to scale. This work affirms that blockchain-based accounting can be both practical and private without deviating from established accounting practices.
