What is Proof Cloud?

Proof Cloud is designed to revolutionize the way developers interact with zero-knowledge proofs (ZKPs). Traditionally, accessing high-scale provers has been challenging due to constraints like hardware requirements and costs. Proof Cloud addresses these challenges by making ZKPs manageable through the cloud.

Developed with Google Cloud’s support, Proof Cloud leverages the strengths of both Google and Polyhedra to deliver a powerful solution. We aim to streamline the process of generating zero-knowledge proofs, making advanced cryptographic technologies more accessible to developers across various sectors.

Technological Advancements Behind Proof Cloud

Cutting-Edge Cryptography

Our team of top-tier cryptographers has developed Proof Cloud as the next-generation advancement in our technology stack. Building on the success of interoperability protocols like zkBridge, Proof Cloud incorporates a proprietary combination of algorithms that enhance different aspects of ZKP capabilities. For those interested in a deep dive, detailed papers and technical documentation are available on https://polyhedra.network

Google Cloud Integration

Google Cloud’s advanced technologies are integral to Proof Cloud’s success. Notable components include:

• Google Kubernetes Engine (GKE): A powerful cluster manager for efficient container orchestration.
• Vertex AI: A unified platform for developing and using generative AI.
• Hyperdisk: The latest generation of network block storage.
• Google’s Blockchain Node Engine: Fully managed node hosting for blockchain development.

These tools enhance Proof Cloud’s efficiency, scalability, and reliability.

Expander: The Power Behind Proof Cloud

One of the standout features of Proof Cloud is its support for various zero-knowledge proof systems, including our proprietary Expander system. As highlighted in our demo, users can choose between different prover options, with Expander offering significant performance improvements. Expander is designed to optimize proof generation times and reduce computational costs, making zero-knowledge proofs more efficient and cost-effective. In the future, Proof Cloud aims to support a broad range of proof systems, ensuring developers have access to the latest advancements in the field.

Autoscaling and Shared Resources

Proof Cloud benefits immensely from Google Cloud’s robust infrastructure, particularly its autoscaling capabilities. Zero-knowledge proofs can experience highly variable demand, making autoscaling a crucial feature. Google Cloud’s autoscaling ensures that Proof Cloud can handle fluctuations in proof generation needs without performance loss. This seamless scaling is particularly beneficial for applications with unpredictable workloads.

Additionally, Proof Cloud leverages shared resources to manage high-demand workloads efficiently. By pooling computational resources, Proof Cloud can absorb spikes in demand, passing on these efficiency gains to developers. This approach not only optimizes resource utilization but also helps keep costs manageable.

Data Security with Google Cloud

Security and privacy are paramount when dealing with sensitive data, and Proof Cloud upholds these principles rigorously. By building on Google Cloud’s infrastructure, Polyhedra Network ensures that Proof Cloud users’ data remains confidential and secure. Polyhedra itself does not have access to the proofs or any sensitive information processed through Proof Cloud. This design leverages Google Cloud’s extensive experience in managing private data, offering users the same high level of security and privacy.

Exciting Use Cases for Proof Cloud

Web3 Interoperability

In the Web3 environment, Proof Cloud can set new standards for interoperability. By using ZKP to facilitate efficient transactions, it enhances scalability for applications like ZK rollups, which can process higher transaction volumes.

AI and Machine Learning

Proof Cloud offers a revolutionary approach to handling sensitive data. It allows AI models to train on private datasets without exposing the data, which is crucial for applications in sectors like healthcare.

Finance and Payments

In the financial sector, Proof Cloud leverages ZKP to enhance transaction security and integrity. It enables verification of authenticity without disclosing personal details, improving regulatory compliance and fraud prevention.

Education

Proof Cloud also has potential in transforming the education sector. It can be used to verify academic records and qualifications, helping institutions issue and confirm credentials with greater trust.

Gaming and Entertainment

Our involvement in the gaming sector continues with Proof Cloud. The platform’s advantages in privacy and scalability are particularly beneficial for gaming and entertainment applications.

Benchmarking with Proof Arena

Another significant tool we’ve introduced alongside Proof Cloud is Proof Arena, which addresses the complexities of benchmarking zero-knowledge proof systems. Proof Arena provides a transparent and comprehensive benchmarking process, allowing developers to compare proof systems based on a range of metrics beyond just proof generation speed. It ensures that all systems are tested under the same conditions, providing a fair assessment of their performance. This tool helps developers make informed decisions by offering a complete picture of each proof system’s capabilities.

Getting Started with Proof Cloud

Eligibility and Access

Proof Cloud is designed to be broadly accessible. It is ideal for projects requiring proof capabilities, whether in Web2 or Web3, and for developers interested in exploring ZK technology. To start using Proof Cloud, you’ll need to install Google Cloud CLI and create a storage bucket for prover binaries. More detailed setup instructions are available on our Notion site.

Pricing and Availability

Currently, Proof Cloud is available for free during its beta phase, which is expected to last until November or December. After the beta phase, we will offer several pricing plans, including base, standard, and enterprise options, to accommodate different needs and scales. The enterprise plan will offer unlimited provers, CPUs, and RAM, catering to large institutions and enterprises.

Next Steps and Community Engagement

Proof Cloud represents a major leap forward in the accessibility and efficiency of zero-knowledge proofs. By integrating advanced technologies from Google Cloud and offering a flexible, cost-effective solution, Proof Cloud aims to empower developers across various sectors. From improving scalability in Web3 applications to enhancing security in finance and facilitating the adoption of ZKPs in emerging fields like DeFi and NFTs, Proof Cloud is poised to make a significant impact.
