This post highlights the intriguing application of zero-knowledge proofs (ZKP) in the context of encoding complex problems like Sudoku and video game speedruns. The discussion emphasizes the relationship between NP-completeness and zero-knowledge proofs, detailing how problems can be transformed (e.g., from 3-SAT to Sudoku) to enable ZKPs. The comments point to the practicality of demonstrating ZKP for colored problems and showcase a method to do this efficiently, ultimately suggesting broader applications for ZKP in other P-class problems. This insight showcases both the mathematical elegance and practical implications within the realm of cryptographic proofs.
