Puzzle-based time-lock encryption offers a secure method for time-delayed data access by leveraging computational puzzles that require a predetermined amount of time to solve. This ensures that the encrypted information remains inaccessible until the puzzle is solved, preventing premature access. Unlike traditional time-lock methods reliant on synchronized clocks or external servers, puzzle-based encryption is self-contained, enhancing security and resilience against tampering or synchronization failures. Its deterministic nature guarantees that the delay is consistent and predictable, providing a reliable mechanism for enforcing timed release of sensitive data. This approach is particularly beneficial for applications requiring controlled information dissemination, such as scheduled disclosures, time-sensitive data sharing, or secure communication protocols.
