In this work, we provide a systematisation of knowledge of delay-based cryptography, in
which we discuss and compare the existing primitives within cryptography that utilise a time …

Simultaneous broadcast (SBC) protocols, introduced in [Chor et al., FOCS 1985], constitute
a special class of broadcast channels which, besides consistency, guarantee that all …

Time-lock puzzles are unique cryptographic primitives that use computational complexity to
keep information secret for some period of time, after which security expires. Unfortunately …

The advent of blockchain protocols has reignited the interest in adaptively secure broadcast;
it is by now well understood that broadcasting over a diffusion network allows an adaptive …

With the increasing use of online digital content delivery, such as games, videos, and
magazine articles, there are scenarios where it is crucial to prevent premature revelation of …

Time-lock puzzles are unique cryptographic primitives that use computational complexity to
keep information secret for some period of time, after which security expires. This topic, while …

Conditional information reveal systems automate the release of information upon meeting
specific predefined conditions, such as time or location. This paper introduces a …

The introduction of time-lock puzzles initiated the study of publicly “sending information into
the future.” For time-lock puzzles, the underlying security-enabling mechanism is the …

Time-lock puzzles are unique cryptographic primitives that use computational complexity to
