Decentralized identifiers are open-standard digital identifiers. They enable the creation of verifiable, decentralized identities, hence, helping protect individual data.
Decentralized identifiers allow users to connect and share data with each other without using intermediaries (Facebook, Google, etc). Furthermore, credentials used by these identifiers are easily verifiable since they are stored on the blockchain.
Interest in this technology is increasing mainly because the World Wide Web Consortium announced that decentralized identifiers (DIDs) have become an official Web Standard.
Decentralized identifiers are part of the Decentralized Privacy meta trend.
This meta trend is mainly driven by the growing demand for decentralized data systems (searches for “decentralized data” have grown by 200% in the last two years).
Decentralized social networks, decentralized applications and decentralized search engines are examples of platforms that utilize blockchain technology to develop privacy-focused products.
