I recently talked about Pakistan’s new dive into the crypto world with Raza Rumi on Naya Daur TV. Blockchain is a big idea—a digital record-keeping system that’s secure and spread across many computers, not controlled by any one person or bank. Think of it like a shared notebook where every entry, like a payment or a deal, is written in permanent ink, visible to those allowed to see it, and can’t be erased. Cryptocurrencies, like Bitcoin, are just one use of blockchain, but it’s not the only one! Blockchain can track food, manage loans, or even record property sales. It’s critical to understand this difference—cryptocurrencies get the headlines, but blockchain’s potential, and its problems, go much wider.
Back in 2008, blockchain burst onto the scene, dreamed up by a mysterious figure named Satoshi Nakamoto—maybe one person, maybe a group—promising to shake up banks, governments, and middlemen. It aimed to let people trust a system without needing a boss in charge. By May 31, 2025, this bold dream looks shaky—great on paper, wobbly in reality. I see a spark of change in blockchain, but its flaws—slow speed, crime risks, and unclear benefits—need a hard look. It’s not a superhero; it’s a work in progress, and we must question it.
The Genesis and the Hype
In 2008, during a banking crisis when trust in money systems crumbled, Satoshi Nakamoto wrote a plan for Bitcoin, the first cryptocurrency. It relied on blockchain, a digital ledger where every deal is locked in with clever math. “We have proposed a system for electronic transactions without relying on trust,” Satoshi wrote. Who was Satoshi? Nobody knows—maybe a lone genius, maybe a team. Some guess folks like Hal Finney, an early tester, or Nick Szabo, a tech thinker, but they said no. In January 2009, Satoshi started Bitcoin, creating its first “block” and hiding a news headline: "03/Jan/2009 Chancellor on brink of second bailout for banks." It was a jab at failing banks, showing blockchain could power a new way, free from central control.
By 2010, Satoshi vanished—no more emails, no clues—leaving 1 million Bitcoins, worth billions today, and a hope of freedom. “Bitcoin would be convenient for people who don’t have a credit card,” Satoshi said in 2009, aiming to help those left out by banks. The idea grew.
In 2015, a young thinker, Vitalik Buterin, built Ethereum, using blockchain for “smart contracts”—automatic deals that run themselves, like a vending machine for loans or property. “I’m excited about building systems that empower people,” Buterin said. A 2017 craze saw billions poured into new crypto coins, sparking dreams of change. Beyond crypto, blockchain took off—Walmart used it to track food from farms to stores, keeping it safe. IBM’s Food Trust copied this, with then-CEO Ginni Rometty saying in 2018, “Blockchain is a game-changer for supply chain transparency.” Big banks joined—JPMorgan’s Jamie Dimon, once doubtful, started Onyx in 2020, noting, “Blockchain can be very helpful.”
The Market and Its Meaning
What’s the “blockchain market”? It’s the money spent on blockchain tools—software, networks, and services. In 2023, experts at GlobalData said it was worth $12.4 billion. Think of companies paying to build blockchain for tracking goods, making payments, or securing records in healthcare or finance. By 2024, it grew to $20.1 billion, and some predict $248.9 billion by 2029. That’s a big jump, showing businesses believe in blockchain’s safety and openness. But compare that to the $7.5 trillion moving daily in global money trades—it’s tiny! Crypto like Bitcoin got people excited, and new uses like decentralised finance (DeFi)—a blockchain way to borrow or trade without banks—hit over $100 billion by 2025. Still, not all the money spent brings real wins—some chase big hopes that fizzle.
Over 100 countries, like China and Europe, explore digital money, called CBDCs, using blockchain for secure, fast payments
Enter the Institutions
Big banks and governments haven’t ignored blockchain, but they’re not chasing crypto’s wild side. They’re using the technology to fix old ways. JPMorgan Chase, led by CEO Jamie Dimon, who once called Bitcoin “a fraud” in 2017, changed tune. In 2020, they launched Onyx, using blockchain for fast payments with JPM Coin and a network, Link, for over 400 banks. “Blockchain can improve financial systems,” said Onyx’s Umar Farooq. Goldman Sachs offers crypto trading for big clients and tests blockchain to speed up bond deals. “It can cut costs and save time,” said their digital head, Mathew McDermott, in 2022. BNY Mellon, an old bank, started storing digital assets in 2022, with CEO Robin Vince saying, “They’re here to stay.” HSBC tried blockchain for gold trading, and Citibank uses it for securities.
Even governments test blockchain. Over 100 countries, like China and Europe, explore digital money, called CBDCs, using blockchain for secure, fast payments. The U.S. Federal Reserve’s “FedNow,” started in 2023, speeds up transfers, inspired by blockchain’s quickness. These giants aren’t following Satoshi’s free-for-all dream—they’re shaping blockchain to fit their rules.
Case Study: DBS Bank’s Smart Blockchain Use
Singapore’s DBS Bank, a major player, shows how blockchain works without the messy, open crypto world. Unlike Bitcoin’s public blockchain, where anyone can join, DBS uses a private, controlled version, like a locked notebook, where only trusted users can write in. In October 2024, DBS launched “DBS Token Services” to help big clients. It ties a private blockchain to their payment system, letting deals happen instantly, any time, day or night. A test with Ant International used “Treasury Tokens” to settle payments across currencies fast, no waiting for bank hours. In August 2024, DBS teamed with Enterprise Singapore and others, using blockchain to give grants to 27 tech firms. Automatic rules in the system—called smart contracts—made sure money went only to those who qualified, all clear and trackable.
Since 2020, DBS’s Digital Exchange has used blockchain to handle digital versions of bonds or shares and store crypto safely. It’s not the wide-open Bitcoin style—DBS keeps it secure, follows Singapore’s rules, and makes deals visible to the right people. “Blockchain lets us serve clients anytime, saving money and time,” said DBS’s Lim Soon Chong in 2024. DBS shows blockchain can help banking, not just crypto, in a practical, controlled way.
Could the Fed Follow? Blockchain for Treasury Bonds
If DBS can use blockchain smartly, could the U.S. Federal Reserve use it for Treasury bonds? These bonds are loans the U.S. government sells—$27 trillion worth in 2025, per U.S. Treasury data—to fund itself. Today, buying, selling, and tracking them is slow, with lots of middlemen. Blockchain could act like a super-secure notebook, recording who owns each bond, making deals instant, and showing everyone—buyers, regulators—a clear picture. The Fed might use a private blockchain, like DBS, keeping control to stay safe and follow rules, unlike crypto’s risky, open setup.
Tests hint it’s possible. The Fed’s Project Guardian, with banks like DBS, tries blockchain for bonds, speeding things up and cutting costs. A 2023 Fed report said, “Blockchain could transform how we handle securities.” But it’s tough—billions of dollars in bonds need a system that won’t break, must be hack-proof, and needs clear laws. “We must balance new ideas with safety,” Fed Governor Michelle Bowman said in 2024. Blockchain’s not ready to run the bond show, but a careful, DBS-like approach could make the Fed’s work faster and clearer—if it works out.
Crime’s a problem too—$449.1 million went to ransomware crooks in 2023, per Chainalysis, with crypto hiding illegal deals
The Cracks Emerge
Here’s the reality check. Cryptocurrencies aren’t real money like dollars—they’re unstable and not widely used. Crypto trades hit $100 billion a day in 2025, but that’s small next to $7.5 trillion in regular money trades, says the Bank for International Settlements. “Cryptocurrencies are a sideshow, not a big threat to finance,” said Christine Lagarde in 2021. Blockchain itself struggles—Bitcoin handles 7 deals a second, Ethereum 30, but Visa does 1,700! Fixes to speed them up are clumsy. Bitcoin’s setup uses 150 terawatt-hours of power a year—think a whole country’s worth! “Bitcoin’s energy use is insane,” Elon Musk said in 2021, stopping Tesla from taking it.
Crime’s a problem too—$449.1 million went to ransomware crooks in 2023, per Chainalysis, with crypto hiding illegal deals. Satoshi’s idea—“a payment system based on math, not trust”—gets twisted by thieves. “Crypto helps criminals move dirty money,” warned U.S. Treasury’s Janet Yellen in 2021. In 2014, a big crypto site, Mt. Gox, lost $450 million to hackers, worth $1 billion now. In 2021, Poly Network lost $610 million, and 2022 saw $320 million vanish from Wormhole. “Blockchain’s core is safe, but the apps on it aren’t,” said expert Bruce Schneier in 2019.
Does It Even Fit?
Do we need blockchain? Regular databases—faster, cheaper—often work better for tracking goods, health records, or votes. Private blockchains, like DBS’s, drop Satoshi’s free-for-all idea—funny, right? “Lots of blockchain uses are fixes hunting for a problem,” said Microsoft’s Bill Gates in 2018. Costs sting—Ethereum fees can hit tens or hundreds of dollars. Rules tighten—China bans crypto, the U.S. cracks down. “Crypto faces big legal risks,” said Gary Cohn, ex-Goldman Sachs leader, in 2022. Still, DBS and DeFi show spots where blockchain fits.
Conclusion
By May 31, 2025, blockchain’s future splits. From $12.4 billion in 2023, its market might hit $248.9 billion by 2029, tied to DeFi, digital money, and tracking goods. That growth depends on fixes, but crime and rules worry leaders. “Digital assets need global watchdogs,” said Christine Lagarde in 2024. New tech like quantum computers could break blockchain’s safety, warned Michio Kaku in 2022. Crypto trades may grow, but they’re tiny against regular money, and crime sticks around. Careful uses, like DBS or maybe the Fed, offer hope—if they succeed.
I see the spark in blockchain—Satoshi’s bold stand against broken banks still shines. “I’ve built a cash system with no middleman,” he wrote in 2008, offering a lifeline to the unbanked. Vitalik Buterin’s innovations and DBS’s practical successes show promise. But I’m no fanboy. Cryptocurrency is not real money—its trading, often boosted by speculation and crime, fails to live up to the hype. High-profile hacks like Mt. Gox and Wormhole have exposed deep vulnerabilities. “Blockchain’s promise is real, but it’s often a mess,” said Ray Dalio in 2022. Economist Joseph Stiglitz called Bitcoin “a bubble” back in 2018. Blockchain has potential—to track food, power DeFi, or even modernise bond markets—but it must overcome issues of speed, energy use, and security. Satoshi dreamed of freedom, but crime and chaos still cloud that vision. Yellen, Gates, and Lagarde have pointed out the flaws—and so must we. Blockchain is no hero—it’s just a tool, and it must be tested with care.
