Blockchain is a record-keeping system first developed by the pseudonymous creator of Bitcoin, Satoshi Nakamoto. The premise is simple: Transactions are grouped into blocks, validated by miners, and stored in a chronological "chain" across all nodes (computers) in a network. This means data is widely distributed and readily available to all participants.
That's important because all copies of the data must be identical. If any individual user attempts to edit the information, the network will reject the change and revert the blockchain to its previous state. In other words, a blockchain is a transparent, secure, and self-governing database. And while these ledgers gained fame as the technological underpinning for cryptocurrencies, they can be applied usefully to a wide array of industries.
Among the notable early adopters of blockchain technology are Microsoft (NASDAQ: MSFT), PayPal Holdings (NASDAQ: PYPL), and salesforce.com (NYSE: CRM). Here's what investors need to know about how blockchain could impact the futures of these three companies.
