Publicly verifiable proofs of sequential work


We construct a publicly verifiable protocol for proving computational work based on collision-resistant hash functions and a new plausible complexity assumption regarding the existence of "inherently sequential" hash functions. Our protocol is based on a novel construction of time-lock puzzles. Given a sampled "puzzle" P getsr D<sub>n</sub>, where $n$ is… (More)
