Kohaku is a research and development project championed by the Ethereum Foundation to create a reference implementation for the next generation of smart contract wallets. Its core mission is to enhance both user experience and security on Ethereum. Key features include built-in account recovery, meta-transactions (sponsoring gas fees), and a modular "intent" based system, allowing users to specify what they want rather than how to execute it. The project serves to establish a new standard for wallets across the ecosystem.
Nicolas Mohnblatt and Vadim Lyubashevsky introduce lattice-based post-quantum cryptography. Using hard problems like SIS, they build commitment schemes and a proof system. A "left-right" technique proves knowledge of a committed vector with a small norm. Switching to polynomial rings significantly boosts efficiency.
They discuss Noir’s evolution and their contribution to this accending zkDSL, how subcircuits and subproofs enable mobile proving, how ZKPassport differs from projects like Self and Rarimo, how they integrated ZKPassport in the wild with DevCon and Aztec, and their plans for better UX and user-friendly apps.
A three-day Ethereum Post-Quantum Workshop was organized in Cambridge, London from October 4th to October 6th this year.
Author Bing shares the daily discussions and key takeaways from his on-site participation in the Ethereum Post-Quantum Workshop.
