The chill of the crypto winter is fading. Financial institutions are reigniting their interest in digital assets, and the long-standing debate about whether blockchain truly lives up to The Economist’s 2015 description as a “trust machine” is back in full swing.
To understand where we stand, it helps to look back—way back—to a 15th-century Venetian monk. Luca Pacioli, though neither a technologist nor a banker, revolutionized economic systems by formalizing double-entry bookkeeping. His method, which recorded each transaction in two separate accounts—debit and credit—brought unprecedented accuracy, reduced fraud, and gave business owners deeper insight into operations and profitability.
This seemingly mundane innovation didn’t just improve accounting—it transformed economies. Efficiency soared, commerce accelerated, and the Renaissance flourished. Double-entry bookkeeping became the invisible foundation of modern finance because it was simple, scalable, and reliable. Centuries later, financial statements based on Pacioli’s model are standard across every major enterprise.

The broader lesson? Transformative technologies must pass three public trust tests: Does it work? Is it useful? Is it secure? In other words: capability, value, and reliability.
Today, blockchain advocates believe distributed ledger technology represents the next leap in financial efficiency. In 2009, Satoshi Nakamoto—the pseudonymous creator of Bitcoin—wrote: “The root problem with conventional currency is all the trust that's required to make it work.” Their vision was clear: replace human intermediaries with cryptographic proof, enabling secure, frictionless peer-to-peer transactions without reliance on centralized institutions.
At its core, blockchain builds directly on Pacioli’s legacy. Imagine if a 15th-century Florentine merchant’s ledger updated in real time across every other trader’s books. That’s the essence of a distributed ledger—a system where every participant holds an identical, tamper-proof copy of transaction history. This creates not just double-entry, but triple-entry or even infinite-entry accounting: transparent, immutable, and inherently trustworthy.
Beyond Finance: The Expanding Utility of Blockchain
While this alone is revolutionary, blockchain’s architecture enables far more than just financial applications. As tech entrepreneur Chris Dixon observed, “Thinking of blockchains merely as ledgers for tracking ownership is a mistake. Blockchains aren’t databases—they’re full-fledged computers.”
Yet one of the greatest ironies of the crypto space is that a technology built to enhance financial trust has often generated distrust. While The Economist wasn’t wrong in calling blockchain a “trust machine,” that label may have been premature. Billions in value have been lost during high-profile industry collapses—FTX, Terra, Celsius—leaving many skeptical.
But these failures weren't due to flaws in blockchain protocols. They stemmed from human greed, poor governance, and speculative mania—age-old problems, not technological ones. Just as early airplanes crashed or software bugs caused system failures, emerging technologies face growing pains. AI models hallucinate; EV batteries degrade; apps ship with vulnerabilities. Blockchain networks aren’t immune to bugs or exploits—but their resilience under stress proves their durability.
So what about usefulness? That’s more subjective. Buying cartoon apes as NFTs or day-trading meme coins doesn’t equate to rebuilding global finance. But beyond speculation, responsible innovators are deploying blockchain for real-world impact:
- Delivering secure humanitarian aid to refugees via untraceable digital wallets
- Cutting cross-border payment costs by up to 80% through stablecoin settlements
- Expanding access to financial services for the unbanked
- Providing portable value storage for workers in high-inflation economies
- Enabling transparent supply chains that verify product origins and empower creators
- Modernizing decades-old financial rails with faster, cheaper, and more secure alternatives
These use cases are still in early stages—but their potential for economic and social good is undeniable.
Security and Regulation: The Final Trust Test
Which brings us to the third pillar: security. In finance, security means regulation—the guardrails that protect users and ensure market integrity.
There’s another irony here: the original crypto ideal was a code-based financial system free from government oversight. But that vision now clashes with reality. The realization is setting in: blockchain isn’t replacing traditional finance—it’s modernizing it. And modernization requires collaboration with regulators, not confrontation.
The good news? 2024 marks a turning point in regulatory clarity.
Japan, Hong Kong, Singapore, and the European Union have established comprehensive frameworks for digital assets, emphasizing consumer protection and market stability. The EU’s MiCA (Markets in Crypto-Assets) regulation sets a global benchmark for licensing, transparency, and accountability.
In the U.S., bipartisan momentum is building. Congress is actively considering legislation to regulate stablecoins and digital asset markets—aimed at preventing illicit financing and ensuring reserve transparency. Treasury Secretary Janet Yellen has repeatedly stressed the need for a balanced approach that fosters innovation while safeguarding the financial system.
This shift won’t eliminate risk overnight—but it will dramatically boost public confidence.

Frequently Asked Questions
Q: What makes blockchain a “trust machine”?
A: Blockchain eliminates the need for trusted intermediaries by using cryptography and decentralized consensus. Transactions are verified by network participants and recorded immutably—making fraud extremely difficult.
Q: Are blockchain networks truly secure?
A: Public blockchains like Bitcoin and Ethereum have proven highly resilient to attacks over time. However, security also depends on implementation—exchanges, wallets, and smart contracts can be vulnerable if poorly designed.
Q: Can blockchain work without regulation?
A: While early crypto aimed for decentralization from government control, sustainable adoption requires regulatory frameworks to protect users, prevent crime, and ensure market fairness.
Q: What are real-world uses of blockchain beyond cryptocurrency?
A: Supply chain tracking, digital identity verification, tokenized assets (like real estate), decentralized finance (DeFi), and secure voting systems are all active use cases.
Q: Will blockchain replace traditional banking?
A: Not entirely—but it will transform it. Banks are already integrating blockchain for faster settlements, improved transparency, and lower operational costs.
Q: How does blockchain support financial inclusion?
A: By enabling low-cost transactions and access to digital wallets without needing a traditional bank account—especially impactful in underbanked regions.
