The Internet has become the primary source of information and connections, which has led to a proliferation of online identities. These identities are managed with username-password combinations or third-party authentication services like Google or Facebook. This makes users prone to cyber-attacks and identity theft. Users need an alternative that is private, secure, and easy to manage. Luckily, blockchain technology has just what we need. The article lists the benefits of using blockchain for storing digital identities.

What is blockchain?

A blockchain is a distributed ledger that allows the storage and exchange of information in a decentralized manner. This ledger is a record of transactions between two parties stored on a distributed network of computers. This makes blockchain an ideal solution for securing digital identities.

Blockchain for digital identity: why is it secure?

Traditional username-password combinations are vulnerable to cyber attacks such as phishing, tampering, and man-in-the-middle attacks. Blockchain is secure by design. The blockchain for digital identity protects user identities by allowing users to store private keys in the blockchain network. The network is shared among participants, so if one user’s account is compromised, the other participants’ accounts are also at risk.

Identity fraud and loss with traditional username-password combinations

Username-password combinations are prone to identity fraud and are often the reason behind online identity loss. The username-password combination is the oldest form of digital authentication, but it has many security issues. Usernames and passwords are vulnerable to hacking and are relatively easy to steal.

Blockchain for digital identity: why is it private?

Traditional authentication methods like username-password combinations are not private, and they require users to share personal information with third-party authentication services such as Google or Facebook. These third-party authentication services are often used for account sign-ups, financial transactions, and storing important data, making them a prime target for cybercriminals. The blockchain has two main features that make it a perfect solution for digital identity.

Limitations of blockchain for digital identity

Digital identity is only as good as the blockchain network it is stored in. If the network is hacked, the user risks losing their digital identity. A user’s identity can also be lost if the blockchain is shut down or if the user dies and nobody claims ownership of the digital identity.


Blockchain for digital identity is a secure and private way of storing user information. With the growing popularity of blockchain technology, the demand for digital identity solutions is rising. However, a centralized digital identity solution has its limitations. Therefore, blockchain technology is the best option for storing digital identities. Digital identity solutions using blockchain technology can help prevent identity fraud, ensure privacy, and reduce identity theft.
