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.
Context ∞ Collapsing vector commitments are a significant development in zero-knowledge proofs and rollup technologies, particularly for scaling blockchain transactions. Their efficiency in proof generation and verification reduces computational load on networks. News reports often highlight their role in improving data availability layers and decreasing transaction costs for layer-2 solutions.
