Frequently asked questions

Polybase is a privacy-preserving decentralized database built on zk-STARKs. It offers built-in web3 permissions, including row-level token gating and wallet-based permissions. Polybase allows for the encryption of data using wallets, enabling "self-sovereign data." It also allows for verifiable querying from smart collections. Compared to storing data on-chain, Polybase is significantly cheaper, costing 1000 to a million times less than on-chain storage. Polybase combines the best attributes of web2 databases and blockchains. It aims to solve scalability issues and is suitable for use cases such as decentralized finance, private transactions, asset tokenization, and proof of reserves. Polybase provides a developer-friendly interface and can be easily started in under 5 minutes.

Polybase addresses the lack of privacy in blockchains by providing private transactions and MEV-resistance. It enables privacy-preserving financial markets, private transactions for decentralized exchanges and lending protocols, and privacy for asset tokenization. Polybase also offers an account-based proof system for publicly verifiable audits while keeping customer data private. It achieves this through the use of zk-STARKs, a pluggable architecture, and a developer-friendly interface. Additionally, Polybase has built-in web3 permissions, allowing for row-level token gating and wallet-based permissions. It is more cost-effective than storing data on-chain, being 1000 to a million times cheaper. Polybase combines the best attributes of web2 databases and blockchains to provide a solution for scalable structured data storage in the web3 ecosystem.

MEV-resistance refers to the ability of a blockchain to mitigate the negative impact of Miner Extractable Value (MEV), which is the profit that miners can potentially make by manipulating the order and inclusion of transactions in a block. Polybase achieves MEV-resistance through the use of zero knowledge proofs (ZK proofs). ZK proofs allow for the verification of the correctness of a computation without revealing the underlying data or computation itself. By leveraging ZK proofs, Polybase ensures that the order and inclusion of transactions cannot be manipulated by miners, thereby reducing the potential for MEV.

Polybase is a privacy-preserving decentralized database built on zk-STARKs. It combines the best attributes of web2 databases and blockchains to provide a scalable and efficient solution for storing structured data in the web3 ecosystem. Polybase offers built-in web3 permissions, allowing for row-level token gating and wallet-based permissions. It also enables data encryption using wallets for "self-sovereign data" and verifiably querying Polybase from smart collections. Compared to storing data on-chain, Polybase is significantly cheaper, with costs that are 1000 to a million times lower than on-chain storage. It addresses the scalability limitations of blockchains and is designed to support high-frequency trading and other use cases in decentralized finance, markets, asset tokenization, and proof of reserves. Polybase is built on zk-STARKs, has a pluggable architecture, and provides a developer-friendly interface.

ZK Bench is a tool that aims to demystify the performance of popular zero-knowledge (ZK) frameworks. It provides insights and benchmarks for evaluating the performance of ZK frameworks in web3 applications. ZK Bench is set to launch on September 27th.

Polylang is a TypeScript-based programming language used in Polybase, a privacy-preserving decentralized database built on zk-STARKs. Polylang allows developers to declaratively define schemas and functions in a way that is easy to read and understand. It is inspired by TypeScript and JavaScript, making it familiar to developers already familiar with those languages. Polylang enhances privacy on Polybase by enabling features such as row-level token gating, wallet-based permissions, and the ability to encrypt data using wallets for "self sovereign data."

The founders of Polybase are Sid Gandhi (Co-founder & CEO) and Calum Moore (Co-founder & CTO). The key team members include Mateusz (Software Engineer), Nick Ruzicka (Head of BD), Timmy (Software Engineer), and Uros (Devops Engineer).
