About Noir

 

Noir is a domain-specific language designed for SNARK-proving systems.

Developed by Aztec Labs, Noir is an open-source language created to facilitate the safe and seamless construction of privacy-preserving zero-knowledge programs. With its simple and flexible syntax, Noir allows developers to build these programs without requiring prior knowledge of the underlying mathematics or cryptography.

Rust heavily influences the language’s design.

 

Noir: Applications and Uses

Noir is designed to simplify complexity without introducing significant overhead, making it versatile for use in both sophisticated cloud-based backends and user smartphones. 

 Here are some examples of where Noir can be applied:

Full stack development: Developers can use NoirJS, a tool from Aztec Labs, to generate and verify Noir proofs in a JavaScript environment, enabling integration into webpages, games, mobile apps, and any platform supporting JavaScript.

 

Solidity verifiers: Noir can auto-generate Solidity verifier contracts that verify Noir proofs. This allows for non-interactive verification of proofs containing private information in an immutable system.

 

Aztec Contracts: Noir can be used to write smart contracts on the Ethereum Layer 2 privacy blockchain, Aztec Network.

 

The Hashlock Security Rating System

Our Blockchain audits are based on our consistent rating system, in which code is qualified based on its quality, vulnerability, future risk, and complexity. We advise that projects with a rating less than secure should not be deployed, and the Hashlocked rating is reserved for projects that value and invest in ongoing security efforts after the audit to protect their stakeholders.

Benefits of Noir Auditing with Hashlock

 Vastly Experienced with Noir

Our seasoned team of smart contract security auditors and researchers are vastly experienced with the Noir programming language and smart contracts. 

 

Manual Security Research

Engaging in manual security research as part of the auditing process is a critical first benefit of using Hashlock for Noir smart contract audits. This approach involves in-depth analysis by experienced professionals who scrutinize the code for vulnerabilities that automated tools might miss. They examine the contract’s logic, compliance with best practices, and resilience against known attack vectors. This human element in the audit process helps in identifying subtle security flaws or logical errors, which are often overlooked by automated scanning tools.

Comprehensive Vulnerability Detection

Hashlock’s auditing process is designed to detect a wide range of vulnerabilities in Noir smart contracts. The comprehensive nature of this detection process means that even the most sophisticated and hidden flaws can be identified. This thoroughness is vital in ensuring the security and reliability of smart contracts, as even a single overlooked vulnerability can lead to significant losses or breaches.

Contract Optimisation Suggestions

Beyond identifying security vulnerabilities, Hashlock also provides valuable insights into contract optimization. This involves suggesting improvements in the code that can enhance its efficiency, reduce transaction costs (gas fees), and improve execution speed. This aspect of the audit is particularly beneficial for developers looking to optimize their smart contracts for better performance and cost-effectiveness on the blockchain, thus making their applications more appealing and accessible to users.

Regular Updates and Post-Audit Support

Another significant benefit of using Hashlock for Noir smart contract audits is the provision of regular updates and post-audit support.

The blockchain ecosystem is dynamic, with new threats and best practices emerging regularly. Hashlock’s auditing service includes updates in response to these changes, ensuring that the audited smart contracts remain secure over time. Additionally, post-audit support helps developers address any issues that arise after the audit, providing a safety net and ensuring long-term security and functionality of the smart contracts.
