issues of payment failures with Zelle started coming in on Friday morning. Customers nationwide complained of failed transactions, pending payments, and frustration about not knowing where their money went.
Zelle later acknowledged the disruption in a statement, blaming the outage on a third-party glitch. The firm pointed fingers at Fiserv, one of the leading providers of banking technology, as the culprit.
Fiserv Blames Internal Issue

A Fiserv representative acknowledged the problem, saying that the company had an internal technical issue that impacted payment processing for multiple banks. The representative explained that this was not a cyber attack or some kind of malicious activity.

Norway’s giant $1.8tn oil fund expects to save a fifth of its annual trading costs by using artificial intelligence to trade less frequently and more efficiently, in a sign of how the technology could upend global finance.

Nicolai Tangen, chief executive of the world’s largest sovereign wealth fund, told the Financial Times that it was targeting a saving of $400mn from its trading costs of $2bn each year, and it had already achieved close to $100mn.

“We have these AI programmes where you can predict [our buying and selling]. The goal is to save $400mn in trading costs a year — it’s huge numbers,” Tangen said. “Sometimes we buy a company on a Monday and sell it on a Friday because of index changes. Now you can predict this kind of things much better and you can internalise these flows,” he added.

The Norwegian fund is one of the biggest equity investors in the world, owning on average 1.5 per cent of every listed company globally, and it makes more than 46mn trades each year.

A common thread is that stablecoin adoption is decoupling from broader crypto market cycles. When I bought my first stablecoin four years ago, it was as a gateway into crypto. It now offers much more than that. While cryptocurrency trading volumes fluctuate with market sentiment, stablecoin usage is growing steadily, driven by practical applications rather than speculation.

There’s something that stands out about Monday’s suspicious transfer of more than 3,520 BTC ($330.7 million) to privacy coin monero (XMR), a conversion that blockchain sleuth ZachXBT said was probably linked to a hack: coordinated activity in the derivatives market.

Monero, which obscures the sender’s and recipient’s addresses to provide an untraceable currency, has limited liquidity on exchanges, which makes it harder for users to transact without affecting the market and exposes them to slippage, the chance of the price changing for the worse before the deal is finalized.

There are no Covid lockdowns to blame any more – we’re choosing to spend more time at home and by ourselves than in any other period since the 1960s, when official ‘Time Use’ surveys began across Europe, the UK and the US. Compared to 2003, people today spend 240 fewer hours a year connecting in-person with family, friends and co-workers. A decade ago, research showed the average British adult had 5.1 close friends. Now, it’s down to just 3.7 – a 27% drop. Even more worryingly, nearly one in 10 individuals say they now have no close friends at all. That’s a staggering 50% rise in a decade. The problem is so systemic that, in 2024, the World Health Organization founded a new Commission on Social Connection, calling it a “global health priority”.

Across Instagram, Facebook and WhatsApp, Meta Platforms is racing to popularize a new class of AI-powered digital companions that Mark Zuckerberg believes will be the future of social media.

Inside Meta, however, staffers across multiple departments have raised concerns that the company’s rush to popularize these bots may have crossed ethical lines, including by quietly endowing AI personas with the capacity for fantasy sex, according to people who worked on them. The staffers also warned that the company wasn’t protecting underage users from such sexually explicit discussions.

Given many sites and services require age verification, we wanted to develop a system that not only verifies age, but does it in a way that protects your privacy. That’s why we are integrating Zero Knowledge Proof (ZKP) technology into Google Wallet, further ensuring there is no way to link the age back to your identity. This implementation allows us to provide speedy age verification across a wide range of mobile devices, apps and websites that use our Digital Credential API.
We will use ZKP where appropriate in other Google products and partner with apps like Bumble, which will use digital IDs from Google Wallet to verify user identity and ZKP to verify age. To help foster a safer, more secure environment for everyone, we will also open source our ZKP technology to other wallets and online services.
