Twitter co-founder and chief executive Jack Dorsey has made a commitment of one billion US dollars out of his personal fortune to coronavirus relief through his philanthropic fund.

In a series of tweets, Dorsey said that he would transfer his equity in his digital payments group Square to his limited liability corporation Start Small, contributing around 28 per cent of his overall wealth.

It could be the largest amount from a single individual for coronavirus relief at a time when the pandemic is inflicting a heavy toll on lives and causing economic disruption across the globe.

Earlier, Amazon founder Jeff Bezos had pledged 100 million Dollars to help food relief efforts during the pandemic while Facebook founder Mark Zuckerberg had offered more than 25 million Dollars to help research through the Bill & Melinda Gates Foundation. The Gates Foundation last month pledged 125 million US dollars for research.
