WHAT is blockchain’s ap­peal? En­thu­si­asts see it as a new way of do­ing all sorts of busi­ness.

Costs could be lower with­out a cen­tral mid­dle­man do­ing the work of keep­ing track of trans­ac­tions, and charg­ing for it. Banks and stock ex­changes have in­vested heav­ily in de­vel­op­ing blockchain tech­nol­ogy, while re­tail­ers like Wal-Mart are ex­per­i­ment­ing with us­ing blockchain for en­sur­ing food safety.

Cen­tral banks are even spec­u­lat­ing about is­su­ing blockchain-based of­fi­cial cur­ren­cies and other forms of blockchain emerged, of­ten us­ing their own cryp­tocur­ren­cies to fa­cil­i­tate trans­ac­tions. The most prom­i­nent is the ethereum blockchain, some­times de­scribed as a plat­form for so-called smart con­tracts.
