All network participants have access to the distributed ledger and its immutable record of transactions. With this shared ledger, transactions are recorded only once, eliminating the duplication of effort that’s typical of traditional business networks. Blockchain was originally developed by Satoshi Nakamoto in 2008 as a ledger for the cryptocurrency bitcoin. It is not known exactly who Satoshi Nakamoto is, or if it’s a moniker used by a group.

There are attempts to apply blockchain to problems as diverse as contract guarantees, medical record storage, and the fact that trees don’t charge money for the oxygen they produce. Rather than having one single owner, blockchain records are spread out among all their users. Putting all of these elements together meant the ‘double spend’ problem formerly inherent to digital data was solved for the first time.

With blockchain cloud services, transactional data from multiple sources can be easily collected, integrated, and shared. Data is broken up into shared blocks that are chained together with unique identifiers in the form of cryptographic hashes. A private blockchain network, similar to a public blockchain network, is a decentralized peer-to-peer network. However, one organization governs the network, controlling who is allowed to participate, execute a consensus protocol and maintain the shared ledger.
