A Deep Dive into Custom Prover Sets
In the evolving landscape of blockchain technology, zero-knowledge proofs (ZKPs) have emerged as a crucial mechanism to enhance scalability, privacy, and security. These cryptographic protocols allow one party to prove that a statement is true to another, without revealing any information beyond its validity. Among these advancements, Gevulot stands out as a pioneering development, serving as the first decentralized proving layer for the modular stack. This article explores the strategic importance of Gevulot and its novel approach to generality through the implementation of custom prover sets.
Gevulot: Addressing Scalability and Efficiency Challenges
Gevulot’s core objective lies in enhancing the efficiency of zero-knowledge infrastructures, achieved by facilitating on-chain deployment of proof systems and streamlining the delegation of proofs across the network. This enhancement is particularly critical in addressing the scalability challenges associated with validity rollups, thereby broadening the horizons for zkRollup adoption.
Despite the promising features of validity rollups, their widespread adoption faces obstacles due to extensive hardware requirements. By introducing custom prover sets, Gevulot presents a novel solution to efficiently manage the large-scale data inherent in zkRollup network states.
The Role of Custom Prover Sets
At the core of the Gevulot network lies the global prover set, which serves as the foundational layer by signing up provers and allocating them specific workloads. Gevulot introduces custom prover sets to enable a more modular and adaptive approach to data storage and proof computation. This innovation allows the incorporation of specialized external software tailored to diverse use cases, ranging from specialized hardware integration to proprietary prover deployment.
Custom prover sets in Gevulot are akin to having a team of experts, each focusing on what they do best. Consider a scenario where you need a specific type of calculation for your transaction. In the Gevulot network, you can leverage a custom prover set designed exactly for that purpose. By adopting this model, the need for one-size-fits-all software across the network is eliminated. Instead, the system empowers users to choose the external software that best suits their operational needs. This concept is similar to starting with a foundational setup and then layering on additional tools, such as Eigenlayer, to increase functionality. In this case, it's about adding more prover programs and improving the workflow of the network. Through this mechanism, the network achieves a higher degree of customization and meets a wide range of requests with greater precision.
Key Benefits:
Custom prover sets enhance the system in several key ways:
Enhanced Network Efficiency: By distributing data storage and computational tasks to custom prover sets, Gevulot effectively reduces network congestion, facilitating faster transaction processing. It simplifies the complexity of maintaining extensive data repositories across the network.
Innovation and Diversity: Custom prover sets foster a rich ecosystem where a wide range of specialized software can be integrated, promoting innovation and diversity.
Dynamic Network Participation: Gevulot's model supports voluntary participation, enabling the network to dynamically evolve in response to emerging demands and innovations without being confined to a monolithic design.
Voluntary Participation and Transparency
Provers voluntarily participate in custom prover sets, giving them the freedom to choose their involvement. When a transaction is initiated, only participating prover nodes are involved in the proof allocation process. Before provers can join the custom sets, Gevulot tests them to ensure they meet the necessary requirements. To conduct the test, the prover program deployer must provide sample input data, which includes an unknowable variable like the most recent block hash. Gevulot uses this data as a Proof of Workload to verify that provers have the necessary hardware capacity to join and maintain their position. The network informs all users about the number of active provers in custom sets, ensuring transparency in participation decisions.
Fair and Flexible Pricing
In custom prover sets, the pricing for proofs is determined by the prover program deployer, similar to how prices are set in proof markets. This ensures consistency in pricing within each prover set, while allowing for variation across different sets. Consistent pricing within a set ensures fairness and reliability in proof allocation that is supported by the randomness generated by the Verifiable Random Function (VRF). Users also have the flexibility to deploy separate provers with customized pricing, potentially restricting participation to specific individuals. This offers opportunities for tailored pricing strategies to address unique needs and circumstances.
To maintain fairness, a standardized minimum cost is enforced across the network, preventing issues such as proprietary provers offering free proofs or undercutting prices compared to their open-source counterparts. This regulation aims to uphold balanced pricing dynamics, safeguarding against distortion by any single party.
Incentivizing Wider Participation
Gevulot employs a subsidy model to encourage broader participation in custom prover sets. This model dynamically assigns subsidies to custom prover sets based on the percentage participation of nodes from the global prover set. Its goal is to enhance network resilience and decentralization. Having a larger number of active participants distributed across various sets strengthens the network against potential attacks and promotes a more decentralized framework.
Facilitating External Software Communication
Gevulot's architecture enables efficient communication between external programs and prover programs. It involves creating a virtual, isolated network within a Gevulot node, using virtual network interfaces such as TUN/TAP. This setup allows for flexible configurations, wherein each program—whether a prover, verifier, or external software—can communicate over this isolated network. It employs various protocols, including custom protocols, gRPC, or JSON-RPC, based on performance and integration needs. Service discovery within this isolated network leverages mechanisms like mDNS or configuration details passed through the task definition, ensuring programs know where and how to connect. This approach offers node operators the flexibility to maintain strict isolation for security and integrity while providing the capability to integrate a wide range of external software and communication protocols.
Exploring Use Cases
The versatility of Gevulot's custom prover sets enables a myriad of applications, ranging from the integration of specialized computational hardware to the establishment of proprietary prover networks. This flexibility not only enhances the network's computational efficiency but also paves the way for novel functionalities, including improved data interoperability and privacy-focused solutions.
Specialized Hardware Integration
For those requiring intense computational power, Gevulot facilitates seamless integration of custom hardware, making complex operations more accessible. Users can leverage a variety of exotic hardware configurations for specific computational tasks. The sets enable the integration of specialized hardware, such as FPGAs (Field Programmable Gate Arrays), ASICs (Application-Specific Integrated Circuits), TEEs (Trusted Execution Environments) and other custom components, into the system, without requiring changes to core program execution environment.
Interoperability through Proxy Nodes
Gevulot's integration of external software enhances interoperability with other blockchain platforms, enabling provers to function as proxy nodes. This approach significantly broadens the network's capabilities by offering flexibility in data management. Notably, these nodes can facilitate seamless integration with Data Availability layers, such as Celestia, thereby improving data accessibility. Moreover, this framework promotes increased interoperability between various blockchain platforms, enabling the execution of more complex operations. For instance, it becomes feasible for users to route their data for processing or verification across specific blockchain networks, such as Ethereum, in a single transaction.
