Thu, Oct 2, 2025, 12:00 AM

Explore the next generation of Solidity development with Artur Chmaro as he introduces vlayer’s ZK superpowers at ETHGlobal Prague 2025. Learn how vlayer empowers Web3 developers with four groundbreaking features: Web Proofs, Email Proofs, Time Travel, and Teleport—tools that bridge off-chain Web2 data and on-chain verifiability using zero-knowledge proofs. Artur explains vlayer’s new prover-verifier execution model, how to build private, off-chain computations in Solidity, and how to verify them on any EVM-compatible chain. Discover how to integrate HTTP responses, email content, historical blockchain state, and cross-chain data directly into your dApps—without compromising security or UX. This talk also includes information on vlayer hackathon bounties, developer templates, and how to get started with your first zk-enabled dApp using vlayer’s powerful SDK. 00:00 Intro to vlayer superpowers at ETHGlobal Prague 00:32 Overview of four new Solidity superpowers 01:03 Web Proofs and Email Proofs explained 01:29 Time Travel and Teleport for cross-chain data 01:55 New prover-verifier Solidity execution model 02:33 Example: Board Ape ownership check using Time Travel 02:58 How verifier contracts validate prover logic 03:22 Web2 data onchain: Use cases for Web and Email Proofs 03:53 vlayer bounty categories and ideas for hackers 04:42 Getting started: Docs, templates, and setup 05:29 Closing remarks and happy hacking at ETHGlobal Prague _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇨🇿 *ETHGlobal Prague* This workshop is specifically for ETHGlobal Prague, a 3-day hackathon held May 30 - June 1 2025, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!
