Introduction to Provably Docs

At its core, Provably V2 is a middleware solution that enables SQL queries on databases or tabular data to return verifiable results. It can be configured to return raw data, or in privacy-preserving scenarios, Provably supports aggregate SQL queries that return results without revealing underlying sensitive data.

We’ve built a platform to manage and orchestrate the many use cases of the Provably middleware. The platform provides a user interface and API tools for account management, middleware configuration, data collections, natural language–to–SQL queries, and tools for proving and verifying query results.

Provably Middleware V2 enables data owners to allow queries over local data for apps and other insight seekers. Use Provably on public or private data for use cases such as:

• Distributed systems integrity: Ensure blockchains, wallets, and payment systems exchange and collaborate over verifiable data and queries.
• Verifiable analytics: Allow aggregate, privacy-preserving queries on private data to unlock insights and build smarter services.
