Delegated Time-Lock Puzzle. (arXiv:2308.01280v1 [cs.CR])

Time-Lock Puzzles (TLPs) are cryptographic protocols that enable a client to
lock a message in such a way that a server can only unlock it after a specific
time period. However, existing TLPs have certain limitations: (i) they assume
that both the client and server always possess sufficient computational
resources and (ii) they solely focus on the lower time bound for finding a
solution, disregarding the upper bound that guarantees a regular server can
find a solution within a certain …
