The beguiling promise of decentralised finance
And its many perils
THE SCEPTICS have plenty of fodder. The earliest adopters of bitcoin, the original cryptocurrency, used it to buy drugs, while cyber-hackers now demand their ransom in it. Hundreds of millions of dollars of ether, another digital money, were stolen this year after hackers found a bug in some code. Many “believers” are in reality trying to get rich quick from the global mania that has seen the value of cryptoassets reach $2.2trn. Others are freakishly devoted. The entrepreneur who announced in June that El Salvador was adopting bitcoin as an official currency sobbed on stage, claiming it would save the nation.
The crooks, fools and proselytisers are off-putting. Nevertheless, the rise of an ecosystem of financial services, known as decentralised finance, or “DeFi”, deserves sober consideration. It has the potential to rewire how the financial system works, with all the promise and perils that entails. The proliferation of innovation in DeFi is akin to the frenzy of invention in the early phase of the web. At a time when people live ever more of their lives online, the crypto-revolution could even remake the architecture of the digital economy.
