4. Personal Identity Security
Personal identity theft and hacking are hot crimes in the cybercrime domain. In 2019, nearly 14.4 million people fell victim to identity fraud, which roughly translates to about 1 in 15 people. From hacking and violating personal files to forging documents, identity theft comes in many different forms. Blockchain can help combat this menace by storing crucial personal information (for example, social security numbers, birth certificates, address, PAN, etc.) on a decentralized and immutable ledger.
The existing centralized Web 2.0 encounters key concerns like vending personal data to third parties, identity theft, mixing of passwords and usernames, and more. So, it can’t deploy a self-sovereign identity (SSI) for the users. However, blockchain can provide users with comprehensive control of their information in their ID and digital identities. So, Personal Identity Security is one of those use cases of blockchain that paves the way for SSI.

This university used blockchain technology to store certificates and degrees. Moreover, it is the first university to accept cryptocurrencies as payment for tuition.
8. Medical Field:
The use of blockchain technology in the healthcare industry proves to be a lifesaver, especially in terms of data processing. The reason is the medical business has long been exploited. Since medical data is massive, blockchain technology is useful for a small amount of information.
One of the best blockchain use cases in the medical field is the Healthureum system. Based on blockchain technology, it works as a tool to control and account for the data concerning modifications in the medical records. It means that the answer was for data to be saved outside the blocks, whereas the links directing to huge files will be saved on the blockchain.
Different initiatives are available to manage the data encryption problems, like restricting the type of access to patient data or preparing a closed array on the blockchain with restricted access to a supervisory body or other regulatory units.
Some blockchain case studies in the medical field:
- Ambrosus: This blockchain use case follows the custody chain of pharmaceuticals and clinical trials. Food and pharmaceutical firms can use it to optimize QA and supply chain visibility.

What is the difference between a public and private blockchain?
Decentralization, transparency, and immutability are just a few of the advantages that public blockchains have over private blockchains. These advantages make public blockchains more secure and trustworthy, as well as more user-friendly. Public blockchains are also rapid and efficient at processing transactions. As a result, they're perfect for applications that need to manage many transactions. A private blockchain is more secure than traditional networks, one of its key advantages. Hackers will have a much harder time gaining access to sensitive data because the network is decentralized. Conventional systems are inefficient; thus private blockchain networks are far more efficient. Private blockchain networks are also transparent, which means that all network participants can see all of the transactions that have occurred. This can assist businesses in increasing stakeholder trust and openness.
What is the difference between a blockchain and a traditional database?
A database and a blockchain differ in several important ways. A database is centralized, whereas a blockchain is decentralized. For centralized applications, a database is faster and more efficient. Because of its distributed nature, a blockchain is more secure and tamper-proof. Because of its open ledger, a blockchain is more transparent. The cost of maintaining a blockchain is higher. A private blockchain can be used for remote applications, whereas a public blockchain can be utilized for public applications. For decentralized applications, a blockchain is preferable. Hacking a blockchain is more complicated.
How is blockchain technology used to create trust between parties?
By allowing parties to share a secure, tamper-proof ledger of transactions, blockchain technology is used to build trust between them. All parties are engaged in a transaction update so that they could all be confident that the information is correct.
