Verifiable Delay Function (VDF)

cryptography
consensus

A function designed to require a minimum sequential computation time while producing a proof that is quick to verify.

Acronym
VDF
1
definition

A verifiable delay function (VDF) produces an output only after a computation that cannot be meaningfully sped up with parallel hardware. The result includes proof that others can verify quickly.

2
uses

VDFs are studied for randomness, leader election, and time-delay mechanisms. They differ from proof of work because the goal is a predictable delay, not an open-ended race to find a hash below a target.
