Eco-Friendly Blockchain Transactions

Blockchain could slash the cost of transactions and reshape the economy.

Blockchain could slash the cost of transactions and reshape the economy. Transformative applications are still far away. But it makes sense to evaluate their possibilities now and invest in developing technology that can enable them. They will be most powerful when tied to a new business model in which the logic of value creation and capture departs from existing approaches. Such business models are hard to adopt but can unlock future growth for companies. Consider how law firms will have to change to make smart contracts viable. They’ll need to develop new expertise in software and blockchain programming. They’ll probably also have to rethink their hourly payment model and entertain the idea of charging transaction or hosting fees for contracts, to name just two possible approaches. Whatever tack they take, executives must be sure they understand and have tested the business model implications before making any switch. Transformative scenarios will take off last, but they will also deliver enormous value. Two areas where they could have a profound impact: large-scale public identity systems for such functions as passport control, and algorithm-driven decision making in the prevention of money laundering and in complex financial transactions that involve many parties. We expect these applications won’t reach broad adoption and critical mass for at least another decade and probably more. Transformative applications will also give rise to new platform-level players that will coordinate and govern the new ecosystems. These will be the Googles and Facebooks of the next generation. It will require patience to realize such opportunities. Though it may be premature to start making significant investments in them now, developing the required foundations for them—tools and standards—is still worthwhile.
