Interest in cryptocurrencies reignited during the pandemic, driven in part by trillions of dollars in stimulus money that left many investors with “free money” to put to work. And while bitcoin recently tumbled nearly 55 percent from its peak, it remains the most valuable crypto asset in the world, with a market capitalization of around $589 billion. Its investors argue that it’s still a safer bet than stocks during this period of economic upheaval.

A renewed interest in cryptocurrencies — digital currencies that rely on blockchain technology, in which transactions are verified and records maintained by a decentralized system that uses cryptography — is widespread. Large corporations like Tesla, Mass Mutual and KPMG Canada have announced plans to hold cryptocurrency assets in treasury or accept them as payment. Meanwhile, major financial institutions are offering customers more digital asset investment options. Twelve years after bitcoin’s birth, mainstream investors are honing in on the currency, too.

In the midst of this market fascination, a fundamental question still remains. What exactly is cryptocurrency, and why should we care? And what about other industry buzzwords, like blockchain, decentralized exchanges or non-fungible tokens (NFTs)? Are they all just fads that will fade away?

Some have called cryptocurrency a Ponzi scheme, a tool for illicit activities, or a short-term fascination that will be irrelevant in a few years. It’s an understandable mindset, since there’s no intrinsic value in cryptocurrencies — not unlike the U.S. dollar after it stopped being backed by gold in the 1970s. But it’s also a shortsighted one. Blockchain technology, which allows users to exchange information on a secure digital ledger, is extremely useful because it automates contractual arrangements through computer programming.

I’m a firm believer that cryptocurrencies and the blockchain technology that underpins them are here to stay, and understanding how this technology has transformed our environment, and how it will continue to evolve, is critical to succeeding in business.

First steps

Bitcoin took the first major steps towards a truly electronic cash system in 2008, in the midst of one of the worst financial collapses of all time. Governments worldwide were bailing out financial institutions that had been deemed “too big to fail.” Perceptions of economic inequality spurred movements such as Occupy Wall Street, which was fueled by a distrust in banks.

Bitcoin, on the other hand, wasn’t created by a trusted source — in fact, no one knows exactly who invented it. In a 2008 white paper, “Bitcoin: A Peer-to-Peer Electronic Cash System,” Satoshi Nakamoto — the pseudonymous individual presumed to have developed bitcoin — described the currency as a way to securely facilitate financial transactions between parties without having to involve a central intermediary. No longer would people have to put their trust in the large financial institutions that failed them during the financial crisis.

Detractors find the lack of a central authority with blockchain worrisome, but proponents say it’s exactly the point: You no longer have to trust the person or institution you’re dealing with. You only have to trust the algorithms that run the program — and presumably an algorithm will never run off with your money.

Instead, blockchain enables a cooperative of members to run the shared network ledger required to keep track of a currency’s credits and debits. No one can shut down the system so long as a group of computers anywhere in the world is able to connect to the internet and run bitcoin’s software.

Because of bitcoin, today we can uniquely own digital assets and transfer them with the certainty that people can’t spend the same cryptocurrency twice. The transactions that bitcoin-like applications make possible are registered in permanent and immutable digital records for all to see in a common ledger.

By enabling fast and easily verifiable transactions, blockchain technology is also streamlining business operations in banking, supply chains, sustainability, healthcare and even voting. Development in these sectors and others is continuing at an intense pace. Annual global funding of blockchain projects now runs in the billions of dollars. From 2020 to 2021 alone, it jumped from several billion to nearly $30 billion.

Second generation

Since bitcoin’s arrival, we’ve seen a second, more sophisticated generation of cryptocurrencies evolve, with Ethereum as their flagship. Ethereum has its own programming language, enabling users to write and automate self-executing smart contracts, allowing for the creation of tokens for a specific use. For example, imagine that when Uber was founded, it had created an Uber token, and only people who owned Uber tokens could use the rideshare service. Tokens currently power thousands of decentralized applications that give people more privacy and control in a variety of areas, such as internet browsing, financial services, gaming and data storage, among others.

Some critiques of cryptocurrency remain. One growing concern is that cryptocurrencies require a significant amount of energy to run their networks, leading to higher transaction costs, energy waste and limited scalability. Newer cryptocurrencies are attempting to find ways to verify transactions that require less energy.

Some people also worry about ongoing volatility in cryptocurrency markets. A third generation of cryptocurrencies has emerged to address this concern: so-called “stablecoins,” which are pegged to a government-issued currency, a commodity, assets, or basket of assets. For some, stablecoins are serving as an onramp into the world of crypto from the world of traditional finance.

Before a new technology becomes part of everyday life, we often see a long period of development, improvement and consumer adoption. Cryptocurrency and blockchain markets are still in this early development stage, but they’re also moving quickly into the mainstream. The total market capitalization of cryptocurrencies late last year briefly reached the $3 trillion mark, or roughly 15 percent of the U.S. GDP, and there’s been more than $100 billion locked into decentralized finance applications.

Large companies like IBM, Amazon and Bank of America are leading the way by tapping into blockchain technology in their daily business activities. It won’t be long until this market, previously characterized by speculation and wild volatility, will be transformed into a stable infrastructure framework. But companies need to get up to speed on the industry now. Those that commit to doing so will be the ones that thrive.

Houston researchers develop material to boost AI speed and cut energy use

ai research

A team of researchers at the University of Houston has developed an innovative thin-film material that they believe will make AI devices faster and more energy efficient.

AI data centers consume massive amounts of electricity and use large cooling systems to operate, adding a strain on overall energy consumption.

“AI has made our energy needs explode,” Alamgir Karim, Dow Chair and Welch Foundation Professor at the William A. Brookshire Department of Chemical and Biomolecular Engineering at UH, explained in a news release. “Many AI data centers employ vast cooling systems that consume large amounts of electricity to keep the thousands of servers with integrated circuit chips running optimally at low temperatures to maintain high data processing speed, have shorter response time and extend chip lifetime.”

In a report recently published in ACS Nano, Karim and a team of researchers introduced a specialized two-dimensional thin film dielectric, or electric insulator. The film, which does not store electricity, could be used to replace traditional, heat-generating components in integrated circuit chips, which are essential hardware powering AI.

The thinner film material aims to reduce the significant energy cost and heat produced by the high-performance computing necessary for AI.

Karim and his former doctoral student, Maninderjeet Singh, used Nobel prize-winning organic framework materials to develop the film. Singh, now a postdoctoral researcher at Columbia University, developed the materials during his doctoral training at UH, along with Devin Shaffer, a UH professor of civil engineering, and doctoral student Erin Schroeder.

Their study shows that dielectrics with high permittivity (high-k) store more electrical energy and dissipate more energy as heat than those with low-k materials. Karim focused on low-k materials made from light elements, like carbon, that would allow chips to run cooler and faster.

The team then created new materials with carbon and other light elements, forming covalently bonded sheetlike films with highly porous crystalline structures using a process known as synthetic interfacial polymerization. Then they studied their electronic properties and applications in devices.

According to the report, the film was suitable for high-voltage, high-power devices while maintaining thermal stability at elevated operating temperatures.

“These next-generation materials are expected to boost the performance of AI and conventional electronics devices significantly,” Singh added in the release.

Texas falls to bottom of national list for AI-related job openings

jobs report

For all the hoopla over AI in the American workforce, Texas’ share of AI-related job openings falls short of every state except Pennsylvania and Florida.

A study by Unit4, a provider of cloud-based enterprise resource planning (ERP) software for businesses, puts Texas at No. 49 among the states with the highest share of AI-focused jobs. Just 9.39 percent of Texas job postings examined by Unit4 mentioned AI.

Behind Texas are No. 49 Pennsylvania (9.24 percent of jobs related to AI) and No. 50 Florida (9.04 percent). One spot ahead of Texas, at No. 47, is California (9.56 percent).

Unit4 notes that Texas’ and Florida’s low rankings show “AI hiring concentration isn’t necessarily tied to population size or GDP.”

“For years, California, Texas, and New York dominated tech hiring, but that’s changing fast. High living costs, remote work culture, and the democratization of AI tools mean smaller states can now compete,” Unit4 spokesperson Mark Baars said in a release.

The No. 1 state is Wyoming, where 20.38 percent of job openings were related to AI. The Cowboy State was followed by Vermont at No. 2 (20.34 percent) and Rhode Island at No. 3 (19.74 percent).

“A company in Wyoming can hire an AI engineer from anywhere, and startups in Vermont can build powerful AI systems without being based in Silicon Valley,” Baars added.

The study analyzed LinkedIn job postings across all 50 states to determine which ones were leading in AI employment. Unit4 came up with percentages by dividing the total number of job postings in a state by the total number of AI-related job postings.

Experts suggest that while states like Texas, California and Florida “have a vast number of total job postings, the sheer volume of non-AI jobs dilutes their AI concentration ratio,” according to Unit4. “Moreover, many major tech firms headquartered in California are outsourcing AI roles to smaller, more affordable markets, creating a redistribution of AI employment opportunities.”
