Cryptography commitment
WebNow, the Pedersen commitment scheme is asymmetric in this (because a computationally unbounded sender can change commitments); on the other hand, it turns out that a commitment scheme between two computationally unbounded parties is actually impossible; the Pedersen scheme is as close as we can come. Share Improve this answer WebAug 31, 2016 · Cryptography is often the first line of defense against potentially malicious parties. Here, the obvious remedy is to use cryptographic commitments. Both players can commit to their inputs in one time epoch, and then in a later epoch open the commitments and reveal their inputs. A standard commitment satisfies two properties, binding and …
