Title:
Timed Commitments Revisited

Authors: Miguel Ambrona, Marc Beunardeau, Raphaël R. Toledo

Abstract:

Timed commitments (Boneh and Naor, CRYPTO 2000) are a variant of
standard commitments which incorporates a forced opening mechanism
that allows anyone to reveal the committed message, but not before
a certain prescribed date.

Timed commitments have a wide-range of applications such as
contract signing, fair multi-party computation, sealed bid auctions
or new blockchain applications such as preventing front-running or
unbiased randomness generation.

We revisit the notion of timed commitments and propose an alternative
simplified definition. We also provide two new constructions of timed
commitments with different trade-offs.
