Problem
Smart contracts lack direct access to real-world data and historical on-chain data, limiting their utility in decentralized applications. Verifying the authenticity and integrity of off-chain data sources within a smart contract environment is also a significant challenge.
Solution
Vlayer provides a verifiable data infrastructure that allows Solidity smart contracts to access and verify both on-chain and off-chain data using zero-knowledge proofs. This infrastructure introduces Prover and Verifier smart contracts, where the Prover executes off-chain to fetch data from sources like web pages, emails, and other blockchains, while the Verifier operates on-chain to validate the data's authenticity. Vlayer enables developers to build dApps that can react to real-world events, access historical data, and interact with multiple chains in a trustless manner.
Target Audience
Vlayer targets Web3 developers building DeFi, gaming, and other decentralized applications that require access to verified on-chain and off-chain data.
Features
- **Web Proofs (zkTLS):** Verifies the authenticity of web page content and APIs, allowing parsing of JSON data on-chain.
- **Email Proofs (ZK Email):** Verifies the origin and content of emails, enabling parsing of email content using regular expressions.
- **Time Travel:** Enables interaction with the EVM state at specific past blocks, allowing access to historical on-chain data.
- **Teleport:** Facilitates cross-chain interactions within a single Solidity call, enabling smart contracts to interact with multiple blockchains.
- **Prover/Verifier Architecture:** Utilizes off-chain Provers for data retrieval and proof generation, and on-chain Verifiers for proof validation.
- Compatible with Ethereum ecosystem
- Dashboard interface to orchestrate the usage of the underlying features
