Traditional finance industry suffers from inefficiencies that can be solved by distributed ledger technology. One of the key challenges to the adoption of distributed technology is the privacy concerns surrounding transactions, while still maintaining auditability and meeting regulatory requirements. This paper presents a suite of critical business use cases that are prevalent in the traditional finance industry that are primed for the adoption of distributed ledger technology. For each use case, we determine the respective privacy and auditability requirements. In order to meet these requirements, we present a generic encrypted table-based ledger (ETL) notion that generalizes existing encrypted table-based distributed ledgers. Furthermore, we demonstrate how a bank can be audited for various financial audits without violating privacy.

摘要

Traditional finance industry suffers from inefficiencies that can be solved by distributed ledger technology. One of the key challenges to the adoption of distributed technology is the privacy concerns surrounding transactions, while still maintaining auditability and meeting regulatory requirements. This paper presents a suite of critical business use cases that are prevalent in the traditional finance industry that are primed for the adoption of distributed ledger technology. For each use case, we determine the respective privacy and auditability requirements. In order to meet these requirements, we present a generic encrypted table-based ledger (ETL) notion that generalizes existing encrypted table-based distributed ledgers. Furthermore, we demonstrate how a bank can be audited for various financial audits without violating privacy.
