The platform focuses on zero-knowledge (zk) cryptography and uses a third-party protocol for Know Your Customer (KYC).

A pseudonymous user named @0xemirsoyturk said Aleo mistakenly sent KYC documents to his email. These documents included selfies and ID card photos of another person, making him concerned about the security of his own information.

Another user, @Selim_jpeg, confirmed the claim, stating that he also got the KYC documents of another person in his email.

Users must complete this process when signing up for HackerOne — a third-party protocol to collect users’ unencrypted KYC data.Screenshot of Aleo user complaints on X platform. Source: @inversebrah

Zero-knowledge layer-1 blockchain platforms focus on providing enhanced privacy and security for users. They employ zero-knowledge proof cryptographic techniques to enable transactions without revealing specific details, ensuring confidentiality.

This privacy-centric approach makes it challenging for external parties to trace or access sensitive information, offering users greater control over their data. These platforms aim to enhance privacy in blockchain transactions, making them more secure and confidential for participants.

Cointelegraph spoke to Mike Sarvodaya, the founder of Galactica, a layer-1 blockchain infrastructure, who explained that such a protocol should never theoretically allow access to user data. He said:“It’s ironic that a protocol for programmable privacy uses a third party to collect users’ unencrypted KYC data after that leaks to the public. Apparently, when your zk stack is so advanced, you might just forget how to practice basic opsec.”

According to Sarvodaya, the Aleo case ironically underscores the significance of creating storage and proof systems for sensitive data — like Personally Identifiable Information (PII) — based on zero knowledge or fully homomorphic encryption (FHE). In such systems, protocol rules must ensure that no single party can reveal stored data.

The Aleo mainnet is set to launch in the next few weeks, once some final bugs have been taken care of, to bring privacy to crypto transactions, as stated by Aleo Foundation executive director Alex Pruden in an interview with The Block.
