The core components of a decentralized identity system include Decentralized Identifiers (DIDs), which are unique and globally resolvable identifiers. Verifiable Credentials (VCs) store user attributes and can be verified. There's also a decentralized ledger or database for storing DIDs and credential schemas. Additionally, identity wallets enable users to manage, store, and present their DIDs and VCs securely, giving them control over their digital identities.

A CoinJoin is a privacy technique where multiple users combine their Bitcoin transactions into a single transaction, making it harder to trace individual inputs and outputs. By merging transactions, CoinJoin obscures the link between senders and recipients, as external observers cannot easily determine which output belongs to which input. This collective approach increases anonymity by breaking heuristic assumptions (e.g., "one input → one output") used in blockchain analysis. However, CoinJoin’s effectiveness depends on participant diversity and transaction volume.

What are the primary benefits of decentralized identity over traditional systems? Decentralized identity offers enhanced privacy as users control their data, reducing reliance on centralized entities prone to breaches. It improves security through cryptographic verification, minimizing identity fraud. Users enjoy greater autonomy, managing credentials across platforms without repeating verification. Interoperability allows seamless use across services, while eliminating single points of failure enhances system resilience. This model also reduces costs for organizations by shifting identity management to users.
