We’re building open source hardware to improve the security and scalability of blockchain protocols.


The VDF Alliance is a collaborative effort to design and implement efficient Verifiable Delay Functions (VDFs) in software and in hardware. A verifiable delay function is a function that takes a certain amount of time to compute, and cannot be accelerated through parallelization or additional processors. Once computed, the output can be quickly verified by anyone.



Find out about the organizations supporting the open source development of VDF hardware.
