Initially, the blockchain was developed to provide cryptocurrencies. However, the practice has shown that this decentralized database can be helpful in many other industries. So, for example, we already see the use of this technology in the financial sector, logistics, healthcare, trade, tourism, and others. We offer to consider how famous companies have implemented this technology in their work and how it has affected their profits and reputation.
What is blockchain and its other benefits?
Blockchain is a unique database that stores all data in an anonymous form. So, if information gets into the system, no one can modify it, not even its owner. Data can be manually entered into the database by a person or recorded automatically, including through artificial intelligence.

Visa and MasterCard
Visa and MasterCard are two major competitors that operate in finance. Visa was the first to take the risk of using blockchain to create more secure transactions.
MasterCard has spent a lot of time deciding to use the blockchain, but it is already preparing to issue bank cards that will support cryptocurrencies. It is a big step for the entire crypto world and the banking system.
Unilever
Unilever is one of the world leaders in producing food products and household chemicals. For the past few years, it has been using blockchain to track its supply chains and execute secure transactions.
