McKinsey Digital has reported that implementing a complete digital ID-activated system in the selected seven countries can have a significant impact on the world economy. By 2030, this could result in an economic value ranging from 3% to 13% of GDP. However, the advantages of blockchain in digital identity extend beyond economic benefits.

Digital identity is a virtual record that consists of personal information. You can create an online identity for an organization as well as an individual. But personal information can be vulnerable to breaches in a digital ecosystem. So how do you ensure that your identity remains secure and in your control?

Know How Does Blockchain Redefine the Banking Industry?

The Benefits of Blockchain in Digital Identity

Blockchain technology emerged with the introduction of Bitcoin in 2008, offering a secure, transparent, and decentralized system spread across a network of computers.

Ever imagined having full control over your personal data and the ability to determine its usage? Blockchain makes managing and securing your online identity a reality. It has already transformed industries like finance, banking, healthcare, and insurance, and now it is poised to revolutionize the field of digital identity management.

Below are several key advantages of utilizing blockchain technology for managing digital identities:

1. Increased Security

Blockchain-based identity verification systems provide secure storage for personal information, reducing the risk of data breaches and identity theft. You maintain control over your data through cryptographic keys, enhancing your security and protecting your personal data and privacy.

2. Enhanced Privacy

Blockchain-based identity systems offer enhanced privacy by utilizing a decentralized and virtually hack-proof infrastructure. You have the power to decide what information to share and with whom, eliminating worries about hackers or third-party interference.

3. Reduced Fraud

Blockchain's tamper-proof system reduces identity fraud by providing a secure identity verification process. Its effectiveness can be observed in supply-chain industries, where distributed ledger technology records transactions in real time, improving security, accountability, and efficiency.

4. Better Transparency

Blockchain-based identity verification systems store and time-stamp data, ensuring its integrity and preventing unauthorized changes. You become the ultimate controller of your data, managing access and preventing potential fraudsters from compromising your information.

5. Improved User Experience

Control whom to share your data with a blockchain-based identity verification system. Manage your online identity and protect yourself against identity theft! These decentralized identity management systems are fast and secure. So scrape away the old cumbersome methods and switch to a streamlined experience with blockchain.

6. Interoperability

A blockchain-based digital identity system offers streamlined access to services, eliminating the need for multiple login credentials. It provides enhanced security, improves the user experience, and simplifies the login process.

With digital identity, you can easily and securely share your information with trusted parties, reducing the risk of identity theft and fraud. Apply for loans or open bank accounts using a single account, without repetitive paperwork. Blockchain-based digital identity systems make this convenient and secure.

How Blockchain Works in Online Verifiable Identity

The key elements of any blockchain system are:

Decentralized identifiers

Blockchain-based identity systems leverage decentralized identifiers (DIDs) to authenticate and securely share identities with verified parties. These cryptographic keys ensure transparency, efficiency, and tamper-proof management of digital identities, eliminating the need for excessive identification documents.

Distributed ledger technology

Within a blockchain, each of its elements plays a crucial role. A distributed ledger technology or DLT provides security and transparency. It acts as a tamper-proof database that records all transactions and changes in identity information.


Tokens act as digital representations of identity. With tokens, you can verify your identity without having to share all your personal information. But all this is dependent on the blockchain's ability to encrypt and store data immutably.


As an authorized user, you are the only person able to access the information stored on a block. The encrypted data will remain unchanged until you add to it yourself. This way you keep away identity thieves and keep your personal data secure.


Immutability is a key feature of blockchain technology where completed transactions are signed with cryptographic keys, time-stamped, and sequentially added to the ledger. The records stored in the blockchain cannot be modified or corrupted without the agreement of all parties involved.

This combination of DIDs and other key elements makes blockchain systems a powerful tool. They help boost the security and privacy of the blockchain ecosystem.

Challenges and Limitations of Blockchain Adoption in Online Identity

Blockchain offers a combination of privacy, security, and transparency in one comprehensive package! Gartner has forecasted that blockchain will generate up to $3.1 trillion in business value by 2030. The adoption of blockchain-based identity verification systems is also projected to grow exponentially.

But there are still some blockchain adoption challenges for identity management that need to be addressed.

Regulatory and legal barriers hinder the adoption of blockchain-based identity management solutions.

Technical challenges like the complexity of integrating with legacy systems and the lack of standardization need to be addressed.

Interoperability issues arise when different blockchain platforms do not communicate effectively, creating data silos.

Scalability is a concern as blockchain-based identity systems need to accommodate large amounts of data and transaction volumes.

Usability is crucial for mainstream adoption as users need intuitive interfaces to manage their digital identities.

Companies today are working to address these challenges. An evolved and mature blockchain technology will give way to more innovative solutions. With these solutions, you can continue to protect your online ecosystem without worry.

Future Prospects of Blockchain in Online Identity

With increased adoption and innovation, blockchain has the potential to address many of the challenges associated with traditional identity management systems, making it a promising solution for the future. This will also expand the scope and applications of blockchain-based identity verification systems.

1. Decentralized Identity

Governments around the world can benefit from implementing a blockchain-enabled online identity system. It would help streamline and secure governmental processes for ID registration, voting, and registering for governmental programs.

An example of blockchain-based digital identity is the Microsoft Entra Verified ID. KuppingerCole named Microsoft as one of the overall leaders in verifiable IDs in 2022.

2. Financial Security

A decentralized identity management system tracks and maintains records of all finances. IBM found that 91% of banks were actively investing in blockchain solutions in 2018. IBM's is one of the leading examples of blockchain in finance management. So far, 15 major banks in Europe have joined this blockchain-based platform.

3. Cloud and Cyber Security

Blockchain helps prevent data tampering and allows businesses to protect their identity on separate server networks. It has great potential to be used to secure a business’ cyber identity and its cloud.

4. Healthcare

Blockchain can be extremely helpful in improving accessibility to the healthcare sector. It can be used to develop applications or manage medical information and appointments.

Blockchain has the potential to revolutionize online identity maintenance by providing a secure, transparent, and decentralized system that can eliminate the need for centralized identity verification authorities. It can offer users greater control over their personal data and reduce the risk of data breaches and identity theft.

As blockchain technology continues to evolve, its adoption across industries and governments is expected to increase, leading to a brighter future for digital identity management. With the help of blockchain, organizations can enhance customer experience and achieve long-term ROI.
