Attempts at Improving Operational Efficiency with Zero-Knowledge Proofs
The widespread use of zero-knowledge proofs, a trend originated by zcash, has made a big splash with its popularity in scaling.
The application scenarios of zero-knowledge proofs in the current market can be summarized as follows: 1) privacy transaction, 2) storage scaling, and 3) computational scaling.
In the field of storage scaling alone, millions of zero-knowledge proofs are generated every day. For computational scaling (also known as zkrollup, zkvm), there is also a clear trend of growth.
But zero-knowledge proofs have a progressively higher hardware overhead because of the reliance on confidence files, which are cached in memory in order to generate proofs faster and that takes up a lot of memory resources. A graphics card is also needed to speed up the process of generation and verification.
The academic community has tried to address this dilemma by trying the following:
1. zkproof validation splitting, which means splitting a proof into multiple pieces and finally aggregating them after multiple small nodes have completed validation. This reduces the resource pressure on individual devices.
2. Adoption of ASIC-friendly mathematical tools which relies on FPGA/ASIC to accelerate the generation and verification of zkproof.
3. Reduction in the size of zkproof.
