Block's new bitcoin wallet aims to solve a huge problem

Can a hardware wallet be both easy to use and secure?

Block just detailed plans for its self-custody bitcoin hardware wallet, aiming to bring together the often contradictory goals of convenience and crypto security. Block's goal is to monetize the wallet through a subscription service.

The plan, laid out at Block's investor day, aims to make it easier for mainstream individuals to self-custody their own bitcoin — thus enabling total control of it — while offering additional protections that are often not available for self-custody hardware or software wallets. Many other wallets don't have easy backup systems for consumers to access their funds.

To do this, the wallet will include three parts: a mobile app, a hardware device and a self-serve recovery tool. The mobile app, which will presumably be run by Block, will be for everyday, smaller transactions since it is easily accessible for people at all times. "Our wallet breaks up the secret key into three pieces to reduce the stakes of losing any one piece," said Jesse Dorogusker, Block's bitcoin hardware lead.

The hardware wallet, with its "rock" design and fingerprint access, which has been previously detailed, will be used for larger transactions where more security is needed. The hardware wallet would presumably hold the user's private key which a user would set only for transactions above a certain size.

If the mobile app is like a checking account, the hardware wallet is like a savings account, Dorogusker said. "We are designing a system for regular folks, so it has to be resilient and inspire confidence even when things go wrong," he said.

The hardware wallet will also be a security tool if someone loses a phone or switches to a new phone.

The big question: How will this make money for Block? The wallet could be monetized through a subscription service that can help "customers regain access to their funds," Dorogusker said. It could also get referral revenue from sending trading volume to exchanges. Pointing to bitcoin's connection to the rest of Block, Dorogusker said the hardware wallet could connect to Cash App.

"Connecting the wallet and Cash App ecosystems can drive both wallet sales and Cash App trading volume, providing 44 million Cash App actives an easy path to self custody, and providing wallet customers an easy way to buy and sell bitcoin and connect to a broader set of financial services in the markets where Cash App offers them."

Trump allies are questioning US democracy. Tech is letting them.

U.S. election infrastructure is exceedingly secure, and voter fraud here is so rare it’s comparable to your annual chances of getting struck by lightning. Despite this, former President Donald Trump and a long list of allies in the Republican Party have spent the last two years questioning the overall integrity of the U.S. election system. Many of those allies are now candidates themselves, and their coordinated attack on the country’s status as a democracy is not a relic of 2020. Some have already started repeating these “Big Lie” charges ahead of next week’s midterms. And the social platforms that help them spread their message have prepared few measures to stop it.
