A crowdfunding site has launched an online charity to raise cash for chronically ill patients.

Qingsongchou Network Technology Co Ltd, an internet business in Beijing, is using a form of "blockchain technology" to help streamline the process and show where the money raised on its platform goes.

"By using blockchain, or light chain as we call it, people who donate cash will be able to track their donations and see it goes to the right places," said Yu Liang, chief operating officer at Qingsongchou.
