After revealing that his payments firm Square is building a small team to help with bitcoin and cryptocurrency development back in March, CEO Jack Dorsey has revealed more details about the project – even though it's still early days.

In an interview with The Next Web, Dorsey, who is also CEO of Twitter, confirmed that he'd recently hired former Google director Steve Lee to lead the team. Dorsey said that he'd interviewed "tens of candidates" for the post before arriving at Lee as his choice.

The new hire will take responsibility for building the remainder of the team, as well as defining its future path, he said. Square is currently eyeing a maximum of five engineers and one designer, who will likely work on a single project rather than many.

That's because Dorsey aims to "make some step changes to various aspects of the ecosystem, versus an iteration,” he said.

While one would expect devs, the choice of a designer comes as something of a surprise in such a early stage project. Dorsey put this down to the need for the need to make cryptocurrencies more accessible, as well as providing education on the technology.

Joking that the team doesn't want any "jerks," Dorsey also said that it's important any candidates must have good technical abilities.

“We want to see significant open-source contributions to various projects. Bitcoin Core is a great example of that, but there’s others, too," he said.

As for its particular role in the crypto ecosystem, he explained that Square Crypto might conduct “grungy, but meaningful” code reviews in order to speed up development. While there are plenty of devs helping out on cryptocurrency projects, few are working on checking the correctness of the code, Dorsey said – changing that could give a "huge boost" to the space.

Outside that, there's need for work to improve efficiency and security. "There’s still a number of big flaws within the Bitcoin community right now," Dorsey told TNW.

The CEO also indicated that he wants to keep the role of Square in the mechanics of the team to a minimum, ruling out cheap stock options in favor of optional bitcoin salaries in order to build a desire to better "serve the community."

The work carried out by the team should also be open to the public. While it's not set in stone yet, Dorsey suggested Square Crypto could operate like a traditional open-source project.

Aside from the more general development work of the crypto team, Square is eyeing bitcoin technology in its products too. Back in February, Dorsey announced during an interview with podcaster Stephan Livera that there are plans to integrate the lightning network – a still early-stage bitcoin payments tech – with Square’s Cash app.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Bitcoin hash rate slides during U.S. winter storm while markets shrug off mining disruption

The temporary loss of mining power underscores academic concerns that geographic and pool concentration can magnify infrastructure failures, though markets showed little immediate reaction.

What to know:

  • Bitcoin’s hashrate fell about 10 percent during a U.S. winter storm, underscoring how local power disruptions can strain the network’s capacity to process transactions.
  • Researchers have shown that concentrated mining, as seen in a 2021 regional outage in China, can lead to slower block times, higher fees and broader market disruptions.
  • With a few large pools now controlling most of Bitcoin’s hashrate, the network is increasingly vulnerable to localized infrastructure failures, even as the price of BTC remains largely unaffected in the short term.
