Cut-And-Choose is a cryptographic technique used in secure multi-party computation to ensure the honesty of participants. One party prepares multiple copies of a computation or data. The other party then randomly selects a subset of these copies to verify for correctness. The remaining unverified copies are then used for the actual computation. This method incentivizes honest behavior by making it highly probable that any cheating will be detected.
Context
This technique is fundamental in constructing robust cryptographic protocols that function securely even in the presence of malicious actors. It finds application in privacy-preserving technologies and verifiable computations within decentralized systems. News concerning advanced cryptographic methods often references Cut-And-Choose protocols for their role in enhancing the security guarantees of digital interactions.
This research introduces Cryptographic Whistleblowing, a mechanism design primitive that uses provable on-chain penalties to enforce honesty against financially rational colluders.
