Our public sphere faces a confidence crisis. Gitcoin has helped raise $50 million for thousands of causes since 2017, and is on a mission to get society out of its rut.

Their secret is a mathematical idea called quadratic voting, which allocates funding to causes based not just on how much they raise, but how many people support them.

Partnered with the likes of UNICEF and Shell, in addition to almost 4,000 causes, the blockchain-based philanthropy organisation has become a pioneer well beyond the crypto ecosystem.

Azeem Khan, Head of Impact at Gitcoin, tells Leo Nasskau how quadratic voting can transform philanthropy, whether it really needs a blockchain, and how, ultimately, it could foster a regeneration of our entire civic landscape.
