Proof Size Preservation

Definition ∞ Proof size preservation refers to the ability of a cryptographic proof system to maintain a consistently small size for its proofs, regardless of the complexity or scale of the computation being verified. This property is crucial for efficient data storage and transmission, particularly in decentralized systems. It ensures that verification remains lightweight and scalable.
Context ∞ In blockchain technology, proof size preservation is a vital characteristic of zero-knowledge proof systems, such as SNARKs and STARKs, which are used to enhance privacy and scalability. The situation allows for off-chain computation with on-chain verification, reducing network congestion and transaction costs. A critical future development includes continued research and engineering to achieve even smaller proof sizes and faster proof generation times, thereby improving the overall efficiency of verifiable computation on public ledgers.
