The emergence of ChatGPT over a year ago sparked a race among tech giants like Google, Microsoft, and Meta to keep up with advancements in artificial intelligence (AI). As millions of users experiment with AI chatbots, the role of AI in our daily online lives is expected to grow significantly. Tools For Humanity CEO Alex Blania recently discussed concerns about AI driving the majority of online interactions, highlighting the need to distinguish between real people and AI. Blania proposes three solutions to address this issue: KYC (know-your-customer) through government infrastructure, a "web of trust" network, and biometrics like iris scanning. Tools for Humanity is developing Worldcoin, a proof-of-personhood crypto project that aims to authenticate identities online by scanning irises. However, there are concerns about privacy and data security. Blania suggests that blockchain, through its decentralized nature, could be instrumental in ensuring the security and control of personal data. Blockchain's immutability can also protect against identity theft and fraud. Other projects, such as OpenChat and the Rarimo protocol, are exploring blockchain-based solutions for verifying unique identities. Read more AI-generated news on: https://app.chaingpt.org/news
