The History and Development of Co-processors

Co-processors play an important role in the field of computers, responsible for handling specific tasks outside of the CPU. From Apple's M7 motion co-processor launched in 2013 to the GPU proposed by Nvidia in 2007, co-processors enhance overall performance by offloading compute-intensive tasks. This heterogeneous computing architecture allows the CPU to focus on flexible and varied task processing.

In the Ethereum ecosystem, high Gas fees and data access restrictions severely limit the development of applications. This exposes Ethereum's limitations in handling large-scale computations and data-intensive tasks. To break through this bottleneck, ZK co-processors have emerged. They are similar to Ethereum's GPUs, capable of processing complex computations and data tasks while utilizing zero-knowledge proof technology to ensure credibility.

The application range of ZK co-processors is extremely broad, covering almost all real dapp scenarios, such as social, gaming, DeFi, risk control systems, etc. Theoretically, the functionalities that Web2 applications can achieve can be replicated on the blockchain by ZK co-processors, with Ethereum providing security assurance as the settlement layer.

Currently, well-known ZK co-processors in the industry mainly focus on three application scenarios: on-chain data indexing, oracles, and ZKML. Among them, general-purpose ZK co-processors such as Risc Zero, Lagrange, and Succinct have attracted significant attention. These projects converge on the technical path, all adopting wrappers from STARKs to SNARKs, supporting recursive functions, and building dedicated prover networks and cloud computing markets.

Unlike Layer 2, the ZK co-processor is application-oriented rather than user-oriented. It can serve as an off-chain virtual machine component for Layer 2, as well as off-chain computing power for public chain applications, cross-chain data oracles, or cross-chain bridges. This flexibility gives it the potential to reconstruct many middleware within the blockchain ecosystem.

Despite the broad prospects, the development of ZK co-processors still faces many challenges. Issues such as high development thresholds, complex technical requirements, and insufficient hardware support need to be addressed urgently. At the same time, due to similar technical paths, competition among projects is more reflected in resource integration and ecological layout.

Overall, ZK co-processors represent an important direction in the evolution of blockchain technology from decentralization to trustlessness. They are expected to reshape the paradigm of blockchain application development and lay the foundation for large-scale commercial use of Web3. With technological iterations and hardware implementation, we can expect to see comprehensive commercialization of the ZK industry chain in the next market cycle.
