How Jump and Solana vets are building a hyper fast internet for blockchains

Published

on



High-frequency traders are the whiz kids of Wall Street. They either code scripts to execute quick trades to eke out small profits that, multiplied by one or ten thousand times over, result in serious cash. Or they’re able to act milliseconds faster than competitors to score big bets on market swings. Speed is paramount, which is why HFT traders have created their own private networks of internet cables—now, a crypto project called DoubleZero wants to do the same to speed up blockchains.

“We can use a whole different set of technologies that have basically been standard and de facto in the high-frequency trading world… but are not available over the public internet, so they’ve never been applied to blockchain before,” Austin Federa, cofounder of DoubleZero and a former executive at the Solana Foundation, told Fortune.

Federa’s project, which has the same obsession with speed as the firms in Michael Lewis’s famous HFT book Flash Boys, has already attracted capital. DoubleZero Foundation, one of the entities behind the project, announced in early March that it had raised $28 million in a seed round led by marquee crypto investors Multicoin Capital and Dragonfly Capital. Other venture capital firms that contributed were Foundation Capital, Reciprocal Ventures, DBA, Borderless Capital, Superscrypt, and Frictionless. In exchange for their cash, investors received token warrants, or promised allocations of a yet-to-be-launched cryptocurrency, Federa said. 

CoinDesk Solana or Ethereum are like Amazon Web Services or Google Cloud—but decentralized. 

And like any cloud computing network, blockchains have physical servers that process users’ transactions and run programmers’ apps. Currently, when servers that power the Solana blockchain, for example, need to communicate with each other, those signals run over public internet infrastructure, said Federa. DoubleZero aims to create a private network of cables to speed up a blockchain’s processing power.

Jump Crypto, the digital assets subsidiary of HFT firm Jump Trading, and Malbec Labs are the engineering entities behind DoubleZero. They won’t be laying down physical cables to construct the network, said Federa. Not yet, anyway. Rather, the company is cobbling together underutilized bandwidth from HFT firms, private companies, and even individuals to build out a faster physical network of cables than what is currently available for blockchains.

And to make sure that, just like a blockchain, this physical network is decentralized, Federa’s foundation plans to launch its own cryptocurrency to reward those who contribute bandwidth to the project.

Federa’s other cofounders are Mateo Ward and Andrew McConnell. Ward is the former CEO of Neutrona Networks, a portfolio company of Jump Trading that specialized in building private internet networks. And McConnell was a former top engineer at Jump.

Democratic Party fractures in government shutdown fight as activists back primary challenges to supporters of GOP bill

Published

on



The Democratic Party was fracturing Friday as a torrent of frustration and anger was unleashed at Senate Democrats, led by Sen. Chuck Schumer, who faced what they saw as an awful choice: shut the government down or consent to a Republican funding bill that allows President Donald Trump to continue slashing the federal government.

After Schumer announced that he would reluctantly support the bill, he bore the brunt of that anger, including a protest at his office, calls from progressives that he be primaried in 2028 and suggestions that the Democratic Party would soon be looking for new leaders.

Nine other members of the Democratic Caucus — a contingent of mostly swing-state and retiring senators — eventually joined Schumer in voting to advance the Republican funding proposal, providing crucial support to bring it to a final vote. It passed late Friday with Sens. Jeanne Shaheen of New Hampshire and Angus King of Maine voting with Republicans in favor.

Since their election losses, Democrats have been hunkered against a barrage of Trump’s early actions in office, locked out of legislative power and left searching for a plan to regain political momentum. But as Schumer let pass one of the rare moments when the party might regain leverage in Washington, the Democratic Party erupted in a moment of anger that had been building for months.

Many in the party felt the New York Democrat was not showing sufficient fight, arguing that a government shutdown would have forced Trump and Republicans to the negotiating table. Yet for Schumer, who has led Senate Democrats since Trump took office in 2016, the choice ultimately came down to preventing a shutdown that he believed would only hand Trump more power and leave his party with the blame for disruptions to government services.

“A shutdown would allow DOGE to shift into overdrive,” Schumer warned on the Senate floor Friday, referring to the Department of Government Efficiency effort led by Elon Musk.

Schumer voted no on the final vote for the funding bill, which only needed a simple majority to pass. Nonetheless, House Democrats released a stream of angry statements and social media posts aimed at Schumer.

Democratic Rep. Troy Carter of Louisiana shared a photo of Trump and Schumer engaged in conversation with the caption, “A picture is worth a thousand words!”

Even in the Senate, hardly any Democrats were speaking up in support of Schumer’s strategy Friday. It was a remarkable turn for the longtime Democratic leader, leaving him standing practically alone.

Speaker Emerita Nancy Pelosi, his longtime ally and partner in funding fights of the past, said in a statement, “Let’s be clear: neither is a good option for the American people. But this false choice that some are buying instead of fighting is unacceptable.”

Pelosi added that the senators should listen to the women who lead appropriations for Democrats, Rep. Rosa DeLauro of Connecticut and Sen. Patty Murray of Washington. They had proposed a 30-day stopgap plan instead of the Republican proposal that provides funding until September. The Republican bill will trim $13 billion in non-defense spending from the levels in the 2024 budget year and increase defense spending by $6 billion.

As House Democrats, who almost all voted against the bill earlier this week, concluded a retreat in northern Virginia Friday, they also called for their Senate colleagues to show more fight. House Democratic leadership rushed back to the Capitol to hold a news conference and urge senators to reject the bill.

“We do not want to shutdown the government. But we are not afraid of a government funding showdown,” Jeffries said.

He also repeatedly declined to answer questions about whether he had confidence in Schumer.

Other Democrats, such as Kentucky Gov. Andy Beshear, who is seen as a potential presidential candidate in 2028 and also visited the Democratic retreat, called for a broader movement. He mentioned the recent 60th anniversary of peaceful civil rights protests in Selma, Alabama, and argued that Democrats need to find “collective courage.”

“When those individuals marched, there wasn’t one voice,” Beshear said. “There was a collective courage of that group that changed the world. That day opened up the eyes of the country to what was really going on.”

Some were ready to start marching.

“We’re ready to get out of this building and head back to the Capitol at any moment and prevent the government from shutting down,” said Rep. Greg Casar of Texas, chair of the Congressional Progressive Caucus.

“Now is the moment for Democrats to draw a line in the stand and say that we stand very firmly on the side of working class people and against the ultra-rich that are trying to corrupt our government for themselves,” he added.

Meanwhile, some of the nation’s most influential progressive groups warned of serious political consequences for Senate Democrats and predicted a fierce backlash when members of Congress return home next week.

Ezra Levin, co-founder of Indivisible, which has organized hundreds of protests across the nation, said that nearly 8 in 10 of the group’s activists support primary challenges against “Senate Dems who cave on the GOP bill.”

He wrote on social media that the vast majority of those Democratic activists plan to express their anger at town halls or other public events next week. MoveOn, another progressive group that claims nearly 10 million members nationwide, predicted that its activists would also demand answers from Democratic officials in the coming days

“Clearing the way for Donald Trump and Elon Musk to gut Social Security, Medicare and Medicaid is unacceptable. It’s past time for Democrats to fight and stop acting like it’s business as usual,” said Joel Payne, a spokesperson for MoveOn.

Senate Democrats were also mostly unwilling to speak up to defend Schumer’s move. Sen. Raphael Warnock, a Georgia Democrat, even suggested that the party should be looking for new leaders in the coming years.

“I think come ’26, ’28, we’ll get some new leadership,” he said. His office later said Warnock was answering the question broadly.

Mostly, though, senators just lamented that they had been jammed by a Republican Party that has found a new sense of unity under Trump. For years, House Republicans have not been able to muster votes for government funding on their own, forcing them into bipartisan negotiations. This time, they passed the bill on party lines and left Washington.

“We’re stuck with two bad choices presented by a unified Republican front,” said Sen. Mark Warner, a Virginia Democrat.

He voted against the bill, yet said of Schumer’s decision: “These are tough, tough calls.”
