Jack Dorsey and Mark Zuckerberg may be making big plans in the cryptocurrency space, but Vitalik Buterin does not see them as likely to gain much traction.
The engineer widely recognised as the inventor of Ethereum, the world’s most used blockchain, cast doubt on Square chief executive Mr Dorsey’s plan for the company to create a new business focused on decentralised financial services that use Bitcoin.
The largest cryptocurrency does not really have the functionality to do that because it was designed largely to be a “currency of the house”, Mr Buterin said in a Bloomberg Television interview.
“On Ethereum there’s native functionality that allows you to essentially directly put ETH or Ethereum-based assets into these smart contracts, into these lock boxes, where there’s then arbitrary conditions that can govern how those assets get released,” said Mr Buterin, who is one of crypto’s most well-known developers.
“Jack [Dorsey] is basically going to have to essentially create his own system that enforces those rules.”
Mr Zuckerberg’s idea to turn Facebook into a “metaverse company” was also met with scepticism by the crypto mogul. “Metaverse” refers to a vision of an internet-enabled virtual world where people have avatars and interact with digital assets and even corporeal objects via augmented reality.
Mr Zuckerberg is clearly trying to anticipate the next phase of the internet “before the rest of the world goes in some different direction and Facebook is sort of left in the dust”, Mr Buterin said. He noted that Mr Zuckerberg has also been involved with the widely scrutinised Facebook-backed cryptocurrency project Libra – now called Diem.
There is “just a huge amount of mistrust” about Facebook, Mr Buterin said, so constructing its own platform could prove ill-fated. He recommended Mr Zuckerberg build on the existing blockchain instead.
Blockchain and crypto have grown rapidly over the past decade, with concepts that are beginning to challenge dominant players in areas such as finance, technology and consumer products. Established companies from Facebook and Twitter to JPMorgan Chase and Goldman Sachs have been working on ways to incorporate blockchain into their existing businesses. But many young, fast-moving companies have sprung up in the space that show potential for disruption.
Mr Buterin says blockchain technology poses a major threat to Facebook, Twitter and other social networks. He said we could see the established companies eventually losing out to the upstarts.
And he continues to have big plans for the Ethereum network. When asked where he sees it in five to 10 years, Mr Buterin replied, “hopefully running the metaverse”.

Subj: Accelerating in the Middle East
Five years ago, Uber launched in the Middle East. It was the start of an incredible journey, with millions of riders and drivers finding new ways to move and work in a dynamic region that’s become so important to Uber. Now Pakistan is one of our fastest-growing markets in the world, women are driving with Uber across Saudi Arabia, and we chose Cairo to launch our first Uber Bus product late last year.
Today we are taking the next step in this journey—well, it’s more like a leap, and a big one: in a few minutes, we’ll announce that we’ve agreed to acquire Careem. Importantly, we intend to operate Careem independently, under the leadership of co-founder and current CEO Mudassir Sheikha. I’ve gotten to know both co-founders, Mudassir and Magnus Olsson, and what they have built is truly extraordinary. They are first-class entrepreneurs who share our platform vision and, like us, have launched a wide range of products—from digital payments to food delivery—to serve consumers.
I expect many of you will ask how we arrived at this structure, meaning allowing Careem to maintain an independent brand and operate separately. After careful consideration, we decided that this framework has the advantage of letting us build new products and try new ideas across not one, but two, strong brands, with strong operators within each. Over time, by integrating parts of our networks, we can operate more efficiently, achieve even lower wait times, expand new products like high-capacity vehicles and payments, and quicken the already remarkable pace of innovation in the region.
This acquisition is subject to regulatory approval in various countries, which we don’t expect before Q1 2020. Until then, nothing changes. And since both companies will continue to largely operate separately after the acquisition, very little will change in either teams’ day-to-day operations post-close. Today’s news is a testament to the incredible business our team has worked so hard to build.
It’s a great day for the Middle East, for the region’s thriving tech sector, for Careem, and for Uber.
Uber on,
Dara

Hydrogen: Market potential
Hydrogen has an estimated $11 trillion market potential, according to Bank of America Securities and is expected to generate $2.5tn in direct revenues and $11tn of indirect infrastructure by 2050 as its production increases six-fold.
"We believe we are reaching the point of harnessing the element that comprises 90 per cent of the universe, effectively and economically,” the bank said in a recent report.
Falling costs of renewable energy and electrolysers used in green hydrogen production is one of the main catalysts for the increasingly bullish sentiment over the element.
The cost of electrolysers used in green hydrogen production has halved over the last five years and will fall to 60 to 90 per cent by the end of the decade, acceding to Haim Israel, equity strategist at Merrill Lynch. A global focus on decarbonisation and sustainability is also a big driver in its development.
