FHE-DKSAP Final Dev Update
Project Abstract:In the world of Ethereum, as envisioned by its co-founder Vitalik Buterin, privacy remains a persistent challenge. The blockchain, while revolutionary, records every transaction in a way that is transparent and permanent. This means that anyone can trace and scrutinize the flow of digital assets from one address to another. This project details a three-fold mission undertaken during the tenure of cohort 4 to enhance the privacy of Ethereum. The initial stride involved fortifying the security of Dual Key Stealth Addresses (DKSAP) through the integration of Fully Homomorphic Encryption (FHE)—a breakthrough allowing computation on ciphered data without revealing the underlying details. Progressing further, the research acknowledged the critical need for regulatory compliance within the blockchain realm. To reconcile the imperative of privacy with the demands of regulation, the study pivoted towards incorporating zero-knowledge proof protocols into the FHE-enriched DKSAP framework. Lastly, the scope of these advancements was expanded to encompass ‘abstract accounts’ in Ethereum, thereby not only elevating the practicality and adaptability of our scheme but also paving the way for more dynamic and programmable blockchain interactions.

In the exciting context of Ethereum Singapore 2023, we are actively engaged, bridging essential components of the blockchain ecosystem. We will seamlessly integrate Metamask and the Linea smart contract with our cutting-edge FHE-DKSAP technology. Before we go into details, we provide the fundamental information of Metamask and Linea Smart contract.

Leveraging the structure of Abstract Accounting (AA), we intend to integrate the FHE-DKSAP within the transaction intent. In this scenario, Alice, the wallet owner, wishes to transfer funds to Bob. Guided by this transaction intent, Alice will utilize her private key, regardless of its format, to craft the transaction intent within the AA framework. She then authenticates this intent using her signature. This process encompasses the creation of a stealth address based on the FHE-DKSAP scheme. The transaction flow is as outlined below:
