Blockchain is a registry of decentralized data exchanged through secure channels. Blockchain technology allows a group of selected participants to exchange data. Blockchain cloud services make it easy to collect, integrate and share transaction data from multiple sources. The data is broken down into common blocks that are linked to each other by means of unique identifiers in the form of cryptographic hash functions.
Blockchain provides data integrity with a single source of trusted information, eliminating data duplication and increasing data security.
