Blockchain has become one of the most talked about emerging technologies, often mentioned in the same breath as artificial intelligence, virtual reality, Internet of Things, and big data technologies. But as a relatively new technology, it's totally expected that people will not fully comprehend aspects of the technology.

Here are some of the most common, misunderstood aspects about blockchain technology.

1. Blockchain is the same as Bitcoin (and other cryptocurrencies)

Source of misconception: The first and probably the most common misconception about blockchain is that it is the same as Bitcoin or cryptocurrency in general — and it is not hard to spot where this comes from. Blockchain as a technology became popular almost a decade after the release of the Bitcoin whitepaper. It is very common for people to refer to it as the technology that powers Bitcoin, and while this is totally correct, people forget one important fact — blockchain does a lot more than just enabling Bitcoin and other cryptocurrencies.

The truth about blockchain: A blockchain is basically a decentralized ledger of transactions. It follows therefore that a Bitcoin blockchain will record Bitcoin transactions. However, blockchain can record virtually anything of value, not just cryptocurrency transactions, provided that the data can be represented on the chain. For instance, J.P. Morgan announced last year that it was tokenizing Gold bars via its enterprise blockchain known as Quorum. Blockchain has found applications in healthcare, supply chain, oil and gas, in addition to finance.

2. Cryptocurrencies (and by association blockchain) are used for illegal activities

Source of misconception: Cryptocurrency has a reputation (earned or otherwise) of being closely associated with crimes like ransomware attacks, money laundering, drug trafficking, and dark web activities. This is because cryptocurrency transactions are relatively harder to track, and criminals have used cryptocurrency in the past to perpetuate these activities. This has been blown out of proportion by law enforcement agencies and notable figures like Bill Gates and Jamie Dimon.

The truth about blockchain: Truth is, regular fiat currencies (the US dollar and Euro specifically), and not Bitcoin or other cryptocurrencies, remain the main medium of sponsoring criminal activities. A Europol report last year confirmed that Bitcoin and other crypto were not used to sponsor terrorism in the region, contrary to widely held opinions. Furthermore, the ratio of illegal to legal activity in Bitcoin has dropped since it became more popular and widely used. Special agent Lilita Infante at the U.S. Drug Enforcement Administration estimates a drop from 90 percent to 10 percent in the last five years. Actually, banks and other legitimate institutions are adopting blockchain technology for cross-border payment settlements.

3. Blockchain transactions are anonymous

Source of misconception: Again, this comes from a widely held belief that blockchain (actually cryptocurrency) is unregulated. It has been positioned as the antithesis of data-collating centralized systems, and therefore has to be anonymous.

The truth about blockchain: On the contrary, blockchain — especially public blockchains — are open and transparent ledgers that show transactions between different addresses. It's fairly easy to track transactions on a public blockchain using block explorers like Etherscan. Also, KYC requirements at many crypto exchanges make it possible to associate these address with real people. That said, there are privacy-focused blockchains like Z-Cash and Monero which use special cryptographic techniques to shield certain details of transactions.

4. Blockchain will solve all the world’s problems

Source of misconception: Hype. As blockchain technology gained in popularity, so came individuals seeking to apply it to every sector of human endeavor. Likening it to the internet, they created an impression that blockchain can and will address pain points in businesses across all industries. As impressive as it is, blockchain, like every technology before it, has its applications and its limitations.

The truth about blockchain: The extent of blockchain's impact has not yet been fully exploited but it will be preposterous to say that blockchain will solve all the world's woes. Through decentralization, blockchain provides trust, and security thereby removing the need for third parties; this is where its realistic use cases arise. At the moment, issues like scalability need to be addressed for blockchain to become commercially viable.

5. Blockchain applications will work all by themselves, independent of existing technology

Source of misconception: Hype again. On the backs of No. 4, blockchain is sometimes looked at as a standalone, independent technology. Given the hype surrounding blockchain, folks could be forgiven for thinking that the technology will work all by itself, without having to deal with legacy applications and technologies.

The truth about blockchain: Blockchain applications most often must work side by side with other existing technologies and systems, as well as in some cases, with emerging technologies like IoT, AI and others. In the financial sector, for instance, blockchain is incorporated into existing payment systems to facilitate cross-border payment settlements.

6. Blockchain only has application in finance

Source of misconception: This stems from the misconception that blockchain is all about Bitcoin or a new order of currency that will replace fiat.

The truth about blockchain: The fintech sector, more than any other, has adopted blockchain technology since its early days. That said, blockchain applications are spreading across various industries. In addition to the ones mentioned previously, projects like MedRec, PowerLedger, and Vakt are adopting blockchain in healthcare, energy, and the oil and gas industries, respectively.

7. Blockchain is the same as Cloud

Source of misconception: Both are internet-based technologies and involves access to data from different devices, but that's as similar as they get. Cloud service providers like Amazon are introducing enterprise blockchain solutions to cloud-based services.

The truth about blockchain: As a shared ledger, blockchain data is not stored on a central set of servers as is the case with cloud services. Also unlike cloud storage, blockchain doesn't usually hold actual physical information like pdf files rather it makes a record of its existence.

8. Blockchain is a single technology

Source of misconception: This comes from the likening of blockchain to the internet. As there is one internet, some people erroneously believe that there is a single blockchain.

The truth about blockchain: There are several blockchain networks — both private and public. While Bitcoin blockchain is the biggest blockchain, there are other public blockchains like Ethereum and Litecoin as well as private blockchains based on Hyperledger.

While these misconceptions are still prevalent within and outside the blockchain community, efforts are underway to dispel these myths. Education and an open dialog is key in such cases. Those within the blockchain community need to make a concerted effort to truly listen to what those outside are saying. Solution providers also need to understand the business, its issues and pain points, and propose the correct solution, whether blockchain-based or not. Blockchain technology is still in its infancy. Remember when folks did not know what the internet was or when it was nothing but hype? In 20 years or so, we will have a few such stories to laugh at.

Houston lab-test startup seeks $1M for nationwide expansion

Testing Access

Health care industry veteran Jim Gebhart knew there had to be a better way for patients to access lab services, especially those with high health insurance deductibles or no insurance at all.

“This challenge became deeply personal when a close family member developed a serious illness, and we struggled to secure prompt appointments,” Gebhart tells InnovationMap. “It’s incredibly frustrating when a loved one cannot receive timely care simply because of provider shortages or the limited capacity of traditional clinics.”

Driven by the desire to knock down lab-test barriers, Gebhart founded Houston-based TheLabCafe.com in 2024. The platform provides access to low-cost medical tests without requiring patients to carry health insurance. TheLabCafe serves patients in six states: Texas, Georgia, Louisiana, Nevada, New Mexico and Oklahoma. Gebhart, the startup’s CEO, says that by the end of March, LabCafe will be offering services in 20 more states and the District of Columbia.

Gebhart has spent more than 30 years in the lab industry. His career includes stints at Austin-based Clinical Pathology Laboratories, Ohio’s Cleveland Clinic Laboratories and Secaucus, New Jersey-based Quest Diagnostics.

“Since nearly 80 percent of disease diagnoses rely on laboratory testing, I decided to leverage my background to create a more accessible, self-directed process for individuals to order blood and urine tests on their own terms — when and where they need them,” says Gebhart.

So far, Gebhart is self-funding the startup. But he plans to seek $700,000 to $1 million in outside investments in late 2026 to support the nationwide expansion and the introduction of more services.

TheLabCafe contracts with labs for an array of tests, such as cholesterol, hepatitis, metabolic, testosterone, thyroid and sexually transmitted infection (STI) tests. A cholesterol test obtained through TheLabCafe might cost $29, compared with a typical cost of perhaps $39 to $59 without insurance.

A health care professional reviews every test, both when the test is ordered and when the results are delivered, often within 24 hours. After receiving test results, a patient can schedule a virtual visit with a health care professional to go over the findings and learn potential treatment options.

Gebhart says TheLabCafe particularly benefits uninsured patients, including those in Texas. Among the states, Texas has the highest rate of uninsured residents. U.S. Census Bureau data shows 21.6 percent of adults and 13.6 percent of children in Texas lacked health insurance in 2024.

“Uninsured patients often pay the highest prices in the health care system,” Gebhart explains. “We address this by offering straightforward pricing and convenient access to testing without requiring insurance.”

“Our rates are intentionally set to remain affordable, helping individuals take a proactive approach to their health,” he adds. “Regular testing enables people to identify potential health issues early and track their progress as they make lifestyle changes. Ultimately, you can’t measure improvement without data — and laboratory results provide that data.”

Houston geothermal startup secures $97M Series B for next-gen power

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.
