The governments of Australia, Palau, Argentina, and Estonia are experimenting with different forms of decentralized identity solutions.
Zero-knowledge (ZK) proofs — a way of verifying information without revealing the specific contents of that information — have become a popular method for creating decentralized identity products.
Despite the hype, Ingo Rübe, CEO and co-founder of decentralized identity provider KILT Protocol, explained that the highly technical nature of ZK-proofs makes government and institutional adoption difficult.
In an interview with Cointelegraph, the KILT CEO explained that decentralized identifiers such as biometric data could be selectively shared with parties and verified onchain using Merkle Trees — a data structure that all computer scientists understand — with far greater ease, speed, and efficiency than ZK-proofs.
