Webpedersen-commitment - Cryptographic Commitment Schemes. Commitment schemes are a way for one counterparty to commit to a value such that the value committed remains private, but can be revealed at a later time when the committing party divulges a necessary parameter of the commitment process. Strong commitment schemes must be both … WebPedersen commitments are cryptographic algorithms that allow a prover to commit to a certain value without revealing it or being able to change it. When you spend Monero, the value of the inputs that you are spending and the value of the outputs you are sending are encrypted and opaque to everyone except the recipient of each of those outputs.

WebFeb 1, 2024 · Pedersen commitment uses random public generators G and H of a suitable large group where the Discrete Logarithm is hard, thus G and H can safely be assumed distinct. Also, that condition implies no integer w such that G = w H can be found by anyone. These facts are assumed or stated.
