The SEC has granted the Depository Trust & Clearing Corp., or DTCC, a no-action letter allowing it to custody and recognize tokenized stocks, ETFs, and Treasuries on approved blockchains for three years. "Although this program is a pilot subject to various operational limitations, it marks a significant incremental step in moving markets onchain," SEC Commissioner Hester Peirce said in a statement. Bloomberg reports: With the permission, DTCC will also extend their record-keeping to the blockchain, Michael Winnike, global head of strategy and market solutions at DTCC Clearing & Securities Services, said in an interview. "It's the same legal entitlement, the same stock that you would hold in your account from the DTCC in traditional form," Winnike said. [...] The SEC's authorization of tokenization services only applies to a specific set of securities that trade often. The approval includes the Russell 1000 index which represents the 1,000 largest publicly traded US companies, as well as exchange-traded funds that track major indices and US Treasury bills, bonds and notes, Winnike said. "This allows us both to create value for the markets, while staying in a pre-defined pool of highly-liquid securities to start," said Winnike. The firm's ultimate aspiration is to add its entire depository, which represents $100 trillion in securities, to the blockchain, a move that would require further expansion of the no-action relief from the SEC, he said. Winnike said the tokenization service will help bridge the traditional and digital worlds in part because the new technology will have the same legal entitlements and controls as traditional markets, including freezing or forced transfers if assets are stolen. "This enables participants to adopt and integrate, because they know there is a trusted party that can recover their securities as needed" and can address potential errors, he said. The new blockchain service will also allow investors to move assets all the time, not just Monday through Friday when traditional markets are open. "That creates a lot of new utility," Winnike said. "It brings the two ecosystems together."

Cadmium Zinc Telluride: The Wonder Material Powering a Medical 'Revolution'

Cadmium zinc telluride (CZT), a hard-to-manufacture semiconductor produced by only a handful of companies, is enabling a quiet revolution in medical imaging, science, and security by delivering faster scans, lower radiation doses, and far more precise X-ray and gamma-ray detection. "You get beautiful pictures from this scanner," says Dr Kshama Wechalekar, head of nuclear medicine and PET. "It's an amazing feat of engineering and physics." The BBC reports: Kromek is one of just a few firms in the world that can make CZT. You may never have heard of the stuff but, in Dr Wechalekar's words, it is enabling a "revolution" in medical imaging. This wonder material has many other uses, such as in X-ray telescopes, radiation detectors and airport security scanners. And it is increasingly sought-after. Investigations of patients' lungs performed by Dr Wechalekar and her colleagues involve looking for the presence of many tiny blood clots in people with long Covid, or a larger clot known as a pulmonary embolism, for example. The 1-million-pound scanner works by detecting gamma rays emitted by a radioactive substance that is injected into patients' bodies. But the scanner's sensitivity means less of this substance is needed than before: "We can reduce doses about 30%," says Dr Wechalekar. While CZT-based scanners are not new in general, large, whole-body scanners such as this one are a relatively recent innovation. CZT itself has been around for decades but it is notoriously difficult to manufacture. "It has taken a long time for it to develop into an industrial-scale production process," says Arnab Basu, founding chief executive of Kromek. [...] The newly formed CZT, a semiconductor, can detect tiny photon particles in X-rays and gamma rays with incredible precision -- like a highly specialized version of the light-sensing, silicon-based image sensor in your smartphone camera. Whenever a high energy photon strikes the CZT, it mobilizes an electron and this electrical signal can be used to make an image. Earlier scanner technology used a two-step process, which was not as precise. "It's digital," says Dr Basu. "It's a single conversion step. It retains all the important information such as timing, the energy of the X-ray that is hitting the CZT detector -- you can create color, or spectroscopic images."

TerraUSD Creator Do Kwon Sentenced To 15 Years Over $40 Billion Crypto Collapse

An anonymous reader quotes a report from Reuters: Do Kwon, the South Korean cryptocurrency entrepreneur behind two digital currencies that lost an estimated $40 billion in 2022, was sentenced in New York federal court on Thursday to 15 years in prison for fraud and conspiracy. Kwon, 34, who co-founded Singapore-based Terraform Labs and developed the TerraUSD and Luna currencies, previously pleaded guilty and admitted to misleading investors about a coin that was supposed to maintain a steady price during periods of crypto market volatility. Kwon was one of several cryptocurrency moguls to face federal charges after a slump in digital token prices in 2022 prompted the collapse of a number of companies. [...] Kwon was accused of misleading investors in 2021 about TerraUSD, a so-called stablecoin designed to maintain a value of $1. Prosecutors alleged that when TerraUSD slipped below its $1 peg in May 2021, Kwon told investors a computer algorithm known as "Terra Protocol" had restored the coin's value. Instead, Kwon arranged for a high-frequency trading firm to secretly buy millions of dollars of the token to artificially prop up its price, according to charging documents. "I made false and misleading statements about why it regained its peg by failing to disclose a trading firm's role in restoring that peg," Kwon said in court. "What I did was wrong." He also faces charges in South Korea, and under his plea deal, prosecutors won't oppose his transfer abroad after he serves half of his U.S. sentence.
