Necessity is the mother of all inventions! We’ve all heard of this English proverb over and over again. When the grazing grounds for horses that pull carriages in England were in short supply, the steam engine was invented. The cotton gin that allowed for mechanical processing of cotton from the US south was developed because of labour shortages. The Manhattan Project, the erstwhile ARPANET (internet), Telecommunications, the overarching society in itself, and even belief-systems such as religion, it can be argued, were all borne out of the necessities of those times.
Distributed Ledger Technologies such as Blockchain was also envisioned as a solution to the necessities of the modern age. It was created out of the need of eradicating the middlemen, removing the human agency from business and giving the power to mathematical algorithms for settlements.
