The Rise of Artificial Intelligence and the Quest for Proof of Personhood

As artificial intelligence becomes more prevalent, concerns arise about the need to authenticate online identities and discern real people from AI chatbots.

Over the past year, the emergence of ChatGPT and the rapid advancement of artificial intelligence (AI) have prompted tech giants like Google, Microsoft, and Meta to intensify their efforts in AI innovation and adoption. With millions of people experimenting with AI chatbots on a monthly basis, the role of AI in our daily lives, particularly online, is set to expand exponentially. However, this growth also raises concerns about the ability to distinguish between real individuals and AI-driven interactions on the internet. This article explores the concept of “proof of personhood” and the potential solutions to address this challenge.

The Three Approaches to Addressing Proof of Personhood

KYC, Web of Trust, and Biometrics:

According to Alex Blania, CEO and co-founder of Tools For Humanity, there are three main approaches to tackle the issue of proof of personhood. The first is the implementation of government infrastructure, known as know-your-customer (KYC), to authenticate individuals. The second approach involves creating a “web of trust” where individuals assign trust values to each other, forming a network of trusted connections. The third approach, which Blania’s Tools for Humanity is focused on, is using biometrics, such as iris scanning, to authenticate identities online. Their project, Worldcoin, aims to leverage proof-of-personhood crypto technology using orb devices to scan irises.

The Rise of AI and the Need for Proof of Personhood

With the rise of AI, concerns about malicious actors and fake bot accounts have become more prevalent. Many experts believe that AI will exacerbate these issues, making the authentication of individuals’ identities crucial. This is where the concept of proof of personhood becomes essential. By authenticating identities at scale, it becomes possible to distinguish between real individuals and AI-driven interactions online.

The Challenge of Data Security and Blockchain’s Role

One major concern with proof of personhood is the potential risk of data breaches and the leakage of sensitive personal or biometric information. However, blockchain technology offers a potential solution to address this challenge. Blockchain’s decentralized nature ensures that data is stored in a distributed manner, reducing the vulnerability of a single entity controlling the data. Advocates argue that blockchain’s encryption capabilities and decentralized system provide individuals with more control over their personal information, enhancing privacy and autonomy.

Self-Sovereign Identity and Decentralized Systems

Blockchain’s immutability and resistance to tampering make it an attractive solution for self-sovereign identity. The theory behind self-sovereign identity is that individuals can have greater control over their personal data by leveraging blockchain technology. By choosing what data to share and with whom, individuals can enhance their privacy and autonomy. Decentralized systems, such as the decentralized chat app OpenChat, are exploring the use of facial recognition to tackle the challenge of proving unique humanity.

Enhancing Security and Efficiency with Blockchain

Blockchain’s inherent security features make it less susceptible to identity theft and fraud. Its immutability ensures that recorded information cannot be altered or tampered with, reducing the potential for malicious activities. Blockchain acts as a digital vault, allowing individuals to control when, where, and how their data is accessed. Projects like Worldcoin, OpenChat, and the Rarimo protocol are leveraging blockchain to facilitate the verification of unique humanity.


As AI continues to advance and play an increasingly significant role in our lives, the need to authenticate online identities and distinguish between real individuals and AI-driven interactions becomes paramount. The concept of proof of personhood offers a potential solution, with blockchain technology providing the necessary security and decentralization to address concerns about data privacy and control. By leveraging biometrics, KYC infrastructure, and web of trust networks, innovative projects are paving the way for a future where the authenticity of online interactions can be verified, ensuring a safer and more trustworthy digital landscape.
