DIDs enable server-free operation, decentralizing user data and control. This contrasts with profit-driven networks that analyze user data. With DIDs, Feeds offers a user-centric, private, and autonomous social media experience, free from centralized surveillance and data exploitation.

CreDA: Decentralized Credit Scoring

CreDA leverages DIDs to offer decentralized credit scoring for DeFi platforms. By linking on-chain and off-chain financial data using verifiable credentials, CreDA helps DeFi entities assess creditworthiness while protecting user privacy through selective disclosure. This expands access to capital worldwide.

Traditional credit scores rely on centralized credit bureaus, leaving many unbanked or underbanked individuals excluded. CreDA changes this by developing credit assessments based on both traditional banking data as well as Web3 financial transactions. Utilizing DIDs and zero-knowledge proofs, CreDA generates secure, portable credit reports that users control.

Individuals share only specific financial credentials required for credit assessments, minimizing data exposure. CreDA unlocks new opportunities for billions lacking access to loans and financial services. Its privacy-first approach aligned with decentralized values makes it uniquely appealing for DeFi and Web3 applications.

Essentials Superwallet

While DIDs provide a revolutionary model for digital identity, complexity has hindered mainstream usage. The average internet user lacks the technical know-how to manage cryptographic keys and operate on blockchain platforms. Elastos Essentials provides a user-friendly wallet interface that abstracts away blockchain intricacies. For the first time, ordinary people can easily register and leverage decentralized identities without being blockchain experts.

On the Essentials wallet, getting started with DIDs involves just a few intuitive clicks. Users register a unique DID directly on their phone in seconds. The app handles cryptographic key management behind the scenes. Once registered, users can store verifiable credentials like proof of age or education certificates as NFTs in their wallet. They selectively disclose credentials to log into websites, access services, or prove qualifications. No more remembering countless passwords or filling out endless forms.

The Essentials wallet puts the convenience and superpowers of DIDs directly in people’s pockets. Its elegantly simple design makes DID a reality for general consumers rather than just a concept for tech pioneers. By abstracting away complexity, Essentials provides the missing link for global DID adoption. Now anyone can exercise digital autonomy and control their online identities through the power of blockchain.

Potential Real World DID Use Cases

Government and Civic Services

DIDs enable digital identity portability across government services like tax filing, voting, social welfare benefits, and more. Citizens can selectively disclose only the minimum credentials required to access each service, minimizing unnecessary data sharing with authorities. DIDs reduce identity fraud while facilitating remote access and paperless processes for civic services.

Another example is digital voting implemented using DIDs. Voters could access ballots using their DIDs and cast votes linked to their decentralized identities. This enables remote participation while preventing duplicate voting. DIDs align with civic values around privacy and autonomy.

Legal Services

The legal industry is primed for disruption by DIDs. DIDs enable verifiable digital signatures, tamper-proof documentation, and selective disclosure of confidential information.

Legal contracts can integrate DIDs to validate signatories and digitally sign agreements. Smart contracts make contract logic executable based on immutable data from oracles. DIDs provide non-repudiation and make digital contracts enforceable. DIDs allow provable authorship and timestamping of legal documents like affidavits and filings. Lawyers can anonymously submit privileged information, while selectively disclosing credentials to courts.

Arbitration systems can leverage DIDs for digital evidence sharing between parties. Users control access by disclosing selective credentials needed to present claims or defenses. DIDs also enable enforceable digital arbitration rulings. DIDs help firms digitize compliance processes like KYC and AML where clients must prove credentials like nationality, PEP status, accreditation, etc. This increases efficiency and reduces risk.

Overall, DIDs introduce valid digital identities into the legal system. This unlocks paperless processes, remote access, and disintermediation. DIDs represent the first step in bringing legal systems into the digital age while upholding privacy.


Patients can leverage DIDs to control access to their medical records. Healthcare providers must verify their credentials in order to view relevant health data – without exposing unrelated personal details. Patients grant time-limited access only to the minimum health information that providers need.

DIDs enhance medical data privacy while improving care coordination, accuracy, and efficiency. Patients can easily share verified health credentials with new providers, creating a comprehensive unified record across different healthcare systems. This reduces duplication of tests and prevents medical errors.

DIDs also enable advanced applications like remote patient monitoring and telemedicine. Patients can share real-time health data from wearables with healthcare providers, without sacrificing privacy. Overall, DIDs help restore power to patients over their medical information.


Educational institutions can issue digital diplomas, transcripts, certifications and credentials as verifiable credentials linked to students’ DIDs. Students then control access to their academic records, choosing when to prove enrollment or qualifications – without revealing unnecessary personal details.

DIDs eliminate paper-based records and simplify verification processes. Students own their educational credentials on their blockchain-secured decentralized ID, rather than through educational institutions. This gives students life-long permissionless access to their own academic achievements.  

DIDs also enable credential portability across different institutions, workplaces, and geographic borders. Students can seamlessly prove their credentials as they progress through higher education and employment.

Supply Chain Logistics

DIDs introduce transparency and accountability to supply chain operations. Manufacturers can cryptographically sign key data like proof of origin, ingredients, transport conditions, and custody logs as verifiable credentials linked to products’ unique decentralized IDs.

Supply chain partners can then selectively disclose credentials to prove important product attributes like fair trade sourcing or cold chain compliance, without exposing entire databases. This provides accountability while protecting commercially sensitive details.

Consumers can also verify product origins and lifecycle histories to a granular level by accessing relevant supply chain credentials. DIDs enable precision authentication without centralized data sharing across disparate entities. This is a major upgrade over current supply chain tracking methods.

The Future of Identity Belongs to the People

DIDs herald a monumental shift by restoring individual sovereignty over digital identity. After years of centralized data exploitation, DIDs finally enable self-determination and user control. Elastos stands at the forefront of this revolution.
