Collapsing Vector Commitments

Definition

Collapsing vector commitments are a cryptographic primitive allowing a party to commit to a vector of values such that the commitment size is constant regardless of the vector length. A key property is that it becomes computationally infeasible to open the commitment to a different vector after it has been made. This scheme offers efficiency gains in proof systems by reducing the data required for verification. It provides a secure way to commit to large datasets with minimal overhead.
