Blockchain is a technology that helps businesses trust each other. It does this by having a shared record of information that is stored on many computers at the same time. This shared record is called a "ledger" and it is updated every time a new transaction is made. This means that everyone who is connected to the Blockchain can see the same information in real time. Blockchain is also very secure because it uses special methods to make sure only authorized people can access it. Additionally, it is transparent, which means that everyone can see all the information on it. This is possible because every person who is part of the Blockchain has a copy of the information. Lastly, Blockchain is flexible, which means that it can change and adapt as the business needs change. This is possible through the use of special computer programs called "smart contracts."
