The VDF Alliance is a collaborative effort to design and implement efficient Verifiable Delay Functions (VDFs) in software and in hardware. Our goal is to create open source designs that can be manufactured and used by the blockchain community.

 

Our Mission

The VDF Alliance began in early 2019 to evaluate the feasibility of developing fast, open, hardware for computing Verifiable Delay Functions (VDFs). To begin, the team developed CPU and FPGA implementations of an RSA VDF to better understand their potential for hardware acceleration. These implementations were used to solve a 20-year-old cryptographic puzzle at MIT in two months. Now the VDF Alliance is open-sourcing these designs and inviting the community to make them even faster. For more information the VDF FPGA Competition page.


VDFs are an exciting new cryptographic primitive with a number of important applications in blockchain security, scalability, and utility. We hope the collaborative effort to develop open source VDF hardware will inspire more general advancements in open source hardware development, which will be critical to the future of secure, decentralized computing.
