Blockchains may radically transform many facets of business life, but they’re a tool particularly well suited for collaborations. Put simply, blockchains are digital ledgers where several people have joint control over the shared information — a feature that makes them ideal for situations where trust and information sharing are important. The technical design of blockchains makes it virtually impossible anyone to change the contents of the ledger without approval from the other parties. Moreover, they can be paired with smart contracts — programmed codes that are automatically executed once certain conditions are met. – Harvard Business Review
