Worldcoin Secure Future Resolved Security Issues by web3oclock

In recent news, Worldcoin, the cryptocurrency project famous for its proof of humanness protocol, has released audit reports conducted by security consulting firms Nethermind and Least Authority. The reports highlight the security issues identified during the verification phase and provide valuable insights into the measures taken by Worldcoin to address these concerns. This blog post aims to provide a beginner-friendly overview of the situation, explaining the significance of Worldcoin’s protocol, the recent audit reports, and their implications for user security and privacy.

The Significance of Worldcoin’s Proof of Humanness Protocol

Worldcoin gained attention in 2021 when it introduced its proof of humanness protocol, offering free tokens to users who could verify their humanness without compromising their privacy. The protocol utilized an innovative approach, requiring users to have their irises scanned using a device called an “Orb.” This process generated a unique hash of the iris scan without storing any sensitive information. The primary motivation behind this protocol was to combat the rising threat of AI bots and safeguard internet privacy.

The Project Launch and Controversy

After two years of development and beta testing, Worldcoin launched its public platform on July 25, 2024. However, the project faced immediate criticism, with concerns raised by various regulatory bodies. The United Kingdom’s Information Commissioner’s Office (ICO) was reportedly evaluating whether the project violated data protection laws, and the French data protection agency CNIL also questioned its legality. The crypto community was divided, with some viewing the protocol as a dystopian threat to privacy, while others saw it as a necessary measure against malicious AIs.

Worldcoin’s Security Audit Reports

To address the growing concerns surrounding its protocol, Worldcoin commissioned security consulting firms Nethermind and Least Authority to conduct comprehensive security audits. The audits covered various security aspects, including protection against DDoS attacks, implementation errors, key storage, encryption and key signing management, data leakage, and information integrity.

Nethermind’s audit report identified 26 security issues within the protocol. However, the encouraging news is that during the verification phase, 24 of these issues were found to be fixed, indicating Worldcoin’s proactive approach to security. One issue was mitigated, while another was acknowledged, suggesting that the team was aware of it and likely working on a resolution.

Least Authority’s audit report, on the other hand, discovered three issues and offered six suggestions for improvement. Worldcoin promptly addressed these concerns, either by resolving them or planning appropriate solutions.

Security Measures Taken by Worldcoin

The audit reports shed light on the specific areas where Worldcoin’s protocol needed improvement. The project has taken significant steps to fortify its security infrastructure. Among the issues tackled were dependencies on Semaphore and Ethereum, such as “elliptic curve precompile support or Poseidon hash function configuration.” Most importantly, the majority of the identified security issues have already been fixed or mitigated, showcasing Worldcoin’s commitment to user safety and privacy.


Worldcoin’s release of audit reports revealing the resolution of security issues marks a crucial step in addressing concerns about its proof of humanness protocol. The project’s willingness to undergo third-party security audits demonstrates its commitment to transparency and user protection. While the controversial nature of the project continues to draw attention, the latest audit reports provide valuable insights into Worldcoin’s dedication to upholding the highest security standards.

By addressing the identified security vulnerabilities, Worldcoin takes significant strides towards establishing a more secure and trustworthy platform for users seeking to protect their privacy from potential AI threats. As the cryptocurrency space evolves, continuous efforts to prioritize user safety and privacy remain essential, and Worldcoin’s security audit reports serve as a noteworthy example for other projects to follow.
