Abstract: Decentralized Identity is one of the applications of Blockchain and DLTs (Distributed Ledger Technologies), allowing users to store and present their data in a much more private way than with the existing centralized models, while also providing them full control over it. Due to its novelty, various proposals have been made, both for data modeling and for the communication protocols to be used. Some of these models include Verifiable Credentials from W3C or SoulBound Tokens from the Ethereum Foundation. Among the communication protocols, we can find OpenID Connect, which integrates OpenID, an authentication protocol, with OAuth 2.0, an authorization protocol; or DIDComm, a protocol created from its inception with Decentralized Identity as its main model since the beginning. In addition to these, there are other concepts that can complement the use cases of digital identity, such as Non-Fungible Tokens (NFTs), although this type of tokens is focused on transferable assets and, therefore, it is more suitable for adapting to the Web3.0 world the characteristics of travelling tickets, collectibles, or concert tickets.
