Breaking Boundaries in Blockchain Interoperability
Bridging blockchains has always been a challenge, plagued by centralized intermediaries and security vulnerabilities. But what if you could connect Ethereum and Mina seamlessly and securely without trusting any third parties?
Introducing Nori, the game-changing bridge that verifies Ethereum’s state on Mina using zero-knowledge proofs (ZKPs). Say goodbye to risky multisig setups Nori delivers true cryptographic security for cross-chain applications.
How Nori Works
With Nori, Ethereum’s state is verified directly on Mina, unlocking trustless interoperability. Here’s how it works:
Zero-Knowledge Verification: Using Helios, an Ethereum light client, inside a zkVM by Succinct Labs, Nori generates a cryptographic proof of Ethereum’s state.Proof Conversion: The proof is transformed into an o1js-compatible format for Mina.On-Chain Verification: The converted proof is submitted to a zkApp on Mina, updating Ethereum’s state securely and trustlessly.
No intermediaries. No compromises. Just pure ZK-powered security.
Why Trustless Bridges Matter
The history of blockchain is littered with catastrophic bridge hacks (check out the Rekt Leaderboard). The problem? Most bridges rely on trusted multisigs a single point of failure that hackers exploit.
With Nori, trustless zero-knowledge cryptography ensures that Ethereum’s state is verified on Mina without any centralized control. This is the next evolution of secure, seamless cross-chain transactions.
Unlocking New Possibilities
Nori isn’t just a bridge it’s a gateway to limitless innovation:
DeFi & Liquidity: Securely transfer assets cross-chain without centralized risks.Privacy & Identity: Use ZKPs for identity verification while preserving privacy.Developer Ecosystem: The upcoming Nori SDK will make integrating trustless cross-chain verification easier than ever.
First Use Case: The Nori Bridge
Nori’s first big application is ETH transfers to Mina, without any trusted intermediaries:
On Ethereum: Deposit ETH into a smart contract.On Mina: Submit a Merkle proof to a zkApp, which verifies and mints wrapped ETH (wETH) fully trustlessly.
Big Picture
Bridging Mina and Ethereum has always been a massive technical challenge. Mina’s unique architecture requires every transaction to be zk-proven before being archived. Meanwhile, Ethereum isn’t zk-native, making Mina-to-Ethereum verification expensive.
That’s why Lambda Class developed the Aligned Layer, a cryptographic verification layer that enables efficient proof verification on Ethereum. While Aligned Layer handles Mina-to-Ethereum verification, Nori enables Ethereum-to-Mina verification creating a fully trustless, bidirectional bridge between the two networks.
Future is Trustless
Nori is setting a new standard for blockchain security and interoperability. With its upcoming SDK, developers will soon have the ultimate toolkit to build trustless cross-chain applications, DeFi platforms, and wallets with ease.
The era of trusted, insecure bridges is over. It’s time for fully cryptographic, zero-trust blockchain connections.
