Security Audits of Quilibrium’s Cryptographic Protocols

Quilibrium relies on advanced cryptographic protocols such as Triple-Ratchet, Oblivious Transfer, and Verifiable Delay Functions (VDFs) to ensure secure and private computation. A natural question emerges: Have security audits been conducted on these protocols as implemented within Quilibrium?

While historical audits exist for the underlying technologies, the dynamic nature of their deployment in Quilibrium suggests that revisiting these evaluations could further solidify trust in the network’s security.

Leveraging Audited Foundations: The Core Libraries

Quilibrium’s cryptographic backbone is built on established, battle-tested libraries, many of which have been rigorously audited in the past. This reliance on off-the-shelf components significantly narrows the scope of potential vulnerabilities. Here’s a breakdown of the key libraries and their audit pedigrees:

1. Kryptology Library (Now Nekryptology) Originally developed by Coinbase and later abandoned, this library was forked into "nekryptology" for use in Quilibrium. It carries a robust audit history, with detailed reports available here: Nekryptology Audits. While these audits provide a strong starting point, the forked version’s adoption in Quilibrium may merit a fresh review to account for any divergence.

2. VDF Implementation (Adapted from Chia) Quilibrium’s VDF implementation originates from the Chia project, enhanced with larger bit-strength parameters and a tweak to the Fiat-Shamir transform to address an unresolved vulnerability in the original. The foundational audits are part of Chia’s broader security reviews, accessible here: Chia Audit Reports. Given Quilibrium’s modifications, a targeted re-audit could validate the updated implementation’s integrity.

3. Libp2p Library This networking library, integral to Quilibrium’s peer-to-peer architecture, has undergone periodic audits over time. While specific reports aren’t immediately easy to pinpoint, libp2p’s widespread use and recurring evaluations lend it a degree of trustworthiness. Consolidating and referencing these audits would enhance transparency for Quilibrium’s stakeholders.

Quilibrium’s Unique Deployment: Timing an Audit

While the individual libraries boast a solid audit legacy, their integration into Quilibrium’s MPC framework is an evolving endeavor. The network’s codebase remains in flux, adapting to the demands of a decentralized, privacy-preserving system. Conducting a comprehensive audit of this bespoke implementation now could be inefficient—both in terms of cost and relevance—given the ongoing changes. Instead, the optimal moment for a formal audit would come once Quilibrium’s protocol stack stabilizes, ensuring that resources are spent on a mature, finalized system.

wQUIL Wrapped Token Contract

In addition to its core protocols, Quilibrium employs an Ethereum-based wrapped token contract adhering to the ERC-20 standard. This contract has been audited, benefiting from its conventional design and widespread use in the blockchain ecosystem. The audit report is publicly available here: ERC-20 Audit Report. This successful review reinforces confidence in Quilibrium’s blockchain-facing components.
