blockchain

Blockchain is defined as a securely shared decentralized ledger of data. Blockchain technology allows a common group of participants to share data. With blockchain cloud services, transaction data from multiple sources can be easily collected, integrated, and shared. Data is divided into shared blocks that are chained with unique identifiers in the form of cryptographic hashes. Blockchain eliminates data duplication and increases security by ensuring data integrity through a single source of truth. In a blockchain system, forgery and data tampering are prevented as data cannot be changed without the agreement of all parties. A blockchain ledger can be shared but cannot be changed. If someone tries to change the data, all participants will be alerted and it will be known who made the attempt. The main reason why organizations use blockchain technology instead of other data stores is to guarantee data integrity without relying on a central authority. BLOCKCHAİN
