The marriage of blockchain and traditional finance is a paradoxical relationship.
The financial services, banking and payments sectors are among the world’s most regulated. As for blockchain? The Web3 space has traditionally been a bit more of a free-for-all when it comes to regulatory frameworks and adherence to them.
Financial institutions (FIs) handle sensitive data that must remain confidential to comply with regulations like the General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA) and banking-specific rules such as Basel III. These rules mandate strict data confidentiality, capital adequacy and anti-money laundering (AML) compliance. Big banks cannot afford to have counterparties, transaction details and trading strategies exposed on public blockchains.
At the same time, blockchain’s operational ethos is built on a disruptive level of transparency, decentralization and openness. The 2009 Bitcoin whitepaper explicitly sought to remove the need for FIs as centralized intermediaries, in large part by making transactions immutable and visible to anyone with internet access.
This tension between blockchain’s inherent transparency and the need for FIs to maintain customer confidentiality and privacy presents a paradox that FIs must resolve if they aim to unlock blockchain’s transformative potential.
However, as comments made Tuesday (Jan. 21) by Bank of America CEO Brian Moynihan show, the U.S. banking sector will embrace cryptocurrencies if regulators allow it. Bank of America holds over 80 blockchain-related patents, making it one of the leading financial institutions in terms of blockchain IP.
Still, President Donald Trump’s inauguration Monday (Jan. 20) lacked any concrete policy announcements regarding cryptocurrency, despite rumors and promises to the contrary.

For traditional FIs, blockchain technology poses an existential question. How can they use its efficiencies without compromising customer privacy or running afoul of regulators?
On one hand, blockchain’s transparency promises greater accountability, auditability and efficiency in areas like cross-border payments, supply chain finance and securities trading.
On the other, FIs must safeguard sensitive data, such as counterparties, transaction details and trading strategies, which public blockchains inherently expose.
The answer may lie in emerging hybrid blockchain models and privacy-enhancing technologies (PETs).
Hybrid blockchains combine the best of public and private blockchain frameworks. They allow FIs to manage sensitive transactions in a private environment while using the security and interoperability of public blockchains. For example, J.P. Morgan’s Onyx blockchain uses Quorum, an Ethereum-based platform, to facilitate private and secure transactions while maintaining interoperability with public Ethereum networks.
J.P. Morgan released a whitepaper last year titled “Project EPIC: Fueling Tokenized Finance With On-Chain Enterprise Privacy, Identity and Composability,” showing the use of blockchain technology to enhance privacy, identity and composability within financial ecosystems is increasingly being explored by traditional banks and financial players.
PETs further address the confidentiality challenge. Zero-knowledge proofs (ZKPs) and secure multiparty computation (MPC) are also emerging. ZKPs enable one party to prove the validity of a transaction without revealing the underlying data, while MPC allows multiple parties to compute a function collaboratively without exposing their individual inputs. Both solutions are increasingly being adopted by FIs to ensure compliance with privacy laws while embracing blockchain’s capabilities.

The PYMNTS Intelligence report “Blockchain’s Benefits for Regulated Industries” found that blockchain technology has numerous potential benefits to serve the unique needs of regulated industries, including finance.
“As more banks integrate blockchain capabilities, customers will have greater choice in transferring value,” FV Bank CEO Miles Paschini told PYMNTS this month. “We’re blazing the trail for a future where blockchain is just another payment rail.”
Yet, without robust privacy mechanisms, blockchain adoption in financial services may be limited to niche use cases that don’t require stringent data protection.
“The largest financial institutions are eager to explore tokenized assets,” but they require regulatory certainty to do so at scale, Nikola Plecas, head of commercialization at Visa Crypto, told PYMNTS in October.
Ultimately, the relationship between blockchain and traditional finance exemplifies the broader tension between innovation and regulation. By embracing this paradox and investing in privacy-preserving technologies, collaborative frameworks and regulatory clarity, the financial industry can turn blockchain’s transparency from a challenge into a competitive advantage.

We get a lot of press releases here at PYMNTS. We consider all of them, and some are more newsworthy than others. But this one really got our attention. This past week, Diebold Nixdorf made headlines with its announcement of successfully installing two new automated teller machines (ATMs) at the U.S. National Science Foundation’s McMurdo Station in Antarctica. This achievement marks a significant milestone in banking accessibility, to be sure. We would like to meet the crew that installed them. We’d also like to know why they needed two. Was there a line at the first one? More to come on that.
According to Diebold, McMurdo Station is Antarctica’s largest research and logistics hub, supporting a fluctuating population that ranges from fewer than 200 residents during the winter months to up to 1,100 individuals during the summer (October through February). The presence of these ATMs is crucial, it says, as the next closest banking facilities are thousands of miles away, making them the only ATMs on the entire continent. How’s that for a value proposition?
The DN Series ATMs are designed for always-on availability. And why do they need two? One ATM is actively in use, while the second serves as a backup for spare parts, ensuring uninterrupted service in this isolated area. These machines are connected to the DN AllConnect Data Engine, which leverages Internet of Things (IoT) connectivity, machine learning, and artificial intelligence (AI) to monitor their performance. A dedicated team continuously aggregates and analyzes technical data to identify potential issues, enabling remote diagnostics and repairs. The ATM can be maintained by trained staff at NSF McMurdo Station, or the Diebold Nixdorf service team can remotely guide them through the repair process.
Anyway, it got us thinking. Are there other surprising ATMs in extreme locations? Well, of course, there are. Here’s a sampling of what we found.
At an altitude of about 5,364 meters (17,600 feet), the Mount Everest Base Camp in Nepal is another unexpected place to find an ATM. Although it’s not a permanent fixture and is often set up seasonally, it caters to climbers and trekkers who need cash for local transactions. This temporary ATM service underscores the adaptability of banking services in extreme environments.
In some parts of the Amazon rainforest, particularly in Brazil and Peru, ATMs can be found in small villages and towns. These machines are vital for local communities, providing access to cash in areas where digital payment options might be limited. The presence of ATMs here demonstrates how banking services can reach even the most remote communities.
Located in the Tibet Autonomous Region, Nagqu is home to one of the highest ATMs in the world. This region is very remote, with limited infrastructure, making the presence of an ATM a notable example of banking accessibility in extreme environments.
In the Thousand Islands (Kepulauan Seribu) off the coast of Jakarta, Indonesia, there’s a floating ATM. This unique ATM serves the local community and tourists on the islands, demonstrating how banking services can adapt to isolated marine environments.
Longyearbyen, the administrative center of the Svalbard archipelago in Norway, boasts the most northerly ATM. This location is one of the most remote inhabited places on Earth, with limited access to mainland Norway, making the ATM a vital service for residents and visitors.
On a more serious note, the installation of ATMs in places like Antarctica and other remote locations highlights the evolving nature of banking technology. With advancements in IoT, AI and remote diagnostics, it’s becoming increasingly feasible to provide banking services in areas previously considered inaccessible. As we look to the future, it will be interesting to see where else ATMs might appear. Whether it’s on a remote island, at the top of a mountain or even in space, the ability to access cash is becoming more universal than ever. And who knows? Maybe one day, we’ll see an ATM on Mars, serving the first interplanetary travelers.
For now, the presence of ATMs in unexpected places reminds us that banking is not just about transactions; it’s about connecting people and communities across the globe, no matter how remote they might be.
