The article discusses the history of internet login systems and their evolution over time. It highlights the security issues faced by early web-based logins and the improvements made in password storage, encryption, and two-factor authentication. However, it states that blockchain technology has not proven useful in replacing traditional login systems due to scalability and cost issues. The article explores the potential of zero-knowledge proofs (ZKPs) in blockchain-powered logins but acknowledges the current challenges in terms of computational resources and user experience. It mentions a blockchain-based login solution that uses retina scans and ZKPs but notes that it is still more expensive and less scalable than cloud services. Despite these challenges, the article suggests that as advancements in cost efficiency and scalability continue, blockchain-based logins could become more viable in the future.
