Blockchain is a relatively new technology that is often described as “creating trust” or “removing intermediaries.” In this paper, we posit that blockchain is a new form of digitally enabled boundary spanning that allows co-ownership models for the companies in question. Where companies have traditionally employed humans to act as interfaces to the external world, new digital technologies enable a digitized approach to many corporate operations that require interaction toward the external market and environment within which firms must operate. Blockchain is a special subset of digital technologies in this regard, enabling companies to co-operate to control parts of the market and to internalize transaction costs that until now have been a market function: using blockchain companies effectively create a new transaction boundary that means boundary spanning activities can be deeply embedded in core business functions, rather than kept as peripheral actions. This digitally enabled boundary spanning is a key attribute of the emerging digital economy. Understanding its implications is of critical importance for economics, business, and social science literature.
