The financial world is undergoing a quiet revolution. As the United States establishes a clearer regulatory path for stablecoins, a new wave of digital currency innovation is sweeping across traditional finance — from PayPal launching its own stablecoin to Visa and Mastercard integrating stablecoin payments into their global networks. This shift echoes the 1960s credit card boom, but with a transformative twist: blockchain technology is redefining how money moves, settles, and is owned.
At the heart of this transformation lies a deeper narrative — one that traces back to the ambitious but failed Libra project, explores the enduring power of open financial networks like Visa, and uncovers the foundational pillars of crypto innovation. In this article, we’ll examine how blockchain is not replacing traditional finance, but evolving it — layer by layer, protocol by protocol.

The Rise and Fall of Libra: A Lesson in Financial Realism
In 2019, Facebook (now Meta) unveiled Libra — a bold attempt to create a global, multi-currency stablecoin backed by a consortium including Visa, Mastercard, and PayPal. The vision was radical: a decentralized, borderless digital currency for billions. Yet within months, regulatory pressure mounted, key partners withdrew, and the project eventually dissolved.
Why did Libra fail?
According to PlatON founder Sun Lelin, the answer isn’t just political — it’s structural. “Libra was too idealistic,” he explains. “It tried to bypass decades of financial inertia built by institutions like Visa and the U.S. banking system.”
The comparison is striking. Just as early telecom standards like WiMAX failed against the entrenched GSM alliance, Libra underestimated the power of existing financial ecosystems. Visa alone connects over 20,000 banks globally — a network effect impossible to replicate overnight.
But there was another critical misstep: Libra’s decision to peg its value to a basket of currencies rather than the U.S. dollar alone.
“If Zuckerberg had simply said ‘Libra is digital dollar,’ it might have succeeded,” Sun notes. “Instead, it threatened dollar supremacy — and that’s a line no U.S. administration will tolerate.”
This insight reveals a deeper truth: in finance, innovation thrives not by overthrowing systems, but by aligning with them. Today’s successful stablecoins — like USDT and USDC — are fully dollar-backed and compliant. They don’t challenge the dollar; they extend its reach.
Visa’s Open Network: The Power of Financial Republicanism
While Apple Pay or WeChat operate as closed-loop ecosystems, Visa represents something different: an open-loop financial republic.
Unlike closed systems where one company controls users, merchants, and transactions, Visa owns none of these. Instead, it enables collaboration between thousands of banks, processors, and merchants — each with a voice in the network.
This model mirrors a political republic. Large banks act like a “Senate,” wielding influence through scale and contribution. Smaller institutions form the “House,” ensuring broad participation. The result? A resilient, scalable system where no single entity dominates — yet all benefit.
“Visa’s strength isn’t in control — it’s in coordination,” Sun says. “Its open architecture allows innovation without centralization.”
This philosophy is now merging with blockchain. When Visa integrates stablecoins into its rails, it’s not adopting crypto — it’s absorbing it. The network remains intact; only the settlement layer evolves.

The Five Roots of Crypto Innovation
To understand why blockchain matters, we must trace its origins beyond speculation and hype. According to Sun Lelin, crypto’s foundation rests on five intellectual and technological currents:
1. The Open Source Movement
From Linux to Apache, open source proved that decentralized collaboration can build robust, scalable systems. Blockchain inherits this ethos — public ledgers are open for inspection, modification, and improvement by anyone.
2. Cyberpunk Ideals
Rooted in libertarian thought, cyberpunk envisioned a world where privacy, autonomy, and censorship-resistant money were possible. Bitcoin’s creator, Satoshi Nakamoto, drew heavily from this tradition — designing a peer-to-peer electronic cash system free from state control.
3. Distributed Systems
Technologies developed in the 1980s — like Byzantine Fault Tolerance (BFT) — laid the groundwork for networks that function without central oversight. Blockchain applies these principles to finance, enabling trustless consensus across untrusted nodes.
4. Cryptography
Often mislabeled as “encryption,” cryptography encompasses far more — including zero-knowledge proofs and multi-party computation (MPC). These tools allow secure verification without revealing data, forming the backbone of modern wallets and privacy-preserving protocols.
“Cryptography enables trustless systems — where you don’t need to trust people or institutions, only math,” Sun emphasizes.
5. The Evolution of Money
From Mesopotamian clay tokens to gold to digital balances, money has always been a shared record — a collective memory of value. Bitcoin and stablecoins continue this evolution: they are digital ledgers representing consensus on ownership.
Together, these roots explain why blockchain isn’t just another fintech tool — it’s a new paradigm for organizing economic activity.
Financial Infrastructure vs. Financial Institutions: A Critical Distinction
Most people interact with financial institutions — banks, insurers, brokerages — that manage customer accounts and offer services.
But beneath them lies financial infrastructure: systems like DTCC (U.S.), Euroclear (Europe), and China’s CSDC. These entities don’t serve consumers directly. Instead, they handle clearing, settlement, custody, and asset registration — the plumbing of finance.
Blockchain’s greatest impact won’t be in replacing banks, but in upgrading this infrastructure.
Today, cross-border settlements take days (T+2 or T+3). Securities clearing involves multiple intermediaries. But blockchain enables near-instant settlement — effectively achieving T+0 finality.
When DTCC announced plans to tokenize U.S. Treasury bonds on a private blockchain, it wasn’t embracing decentralization — it was optimizing efficiency. The same applies to Visa’s stablecoin integrations: faster settlement means lower counterparty risk and higher liquidity.
From T+3 to Real-Time: Blockchain’s Core Value
Ask most people if their bank transfer is “instant,” and they’ll say yes — but technically, it’s not.
What feels like real-time is often just front-end illusion. When you send money via mobile banking, the bank updates your balance immediately — but the actual interbank settlement may take hours or days.
Blockchain changes this by merging transaction and settlement into one step — atomic settlement.
Imagine sending $100 in stablecoins: the moment you hit “send,” ownership transfers irreversibly on-chain. No waiting for nightly batch processing. No reconciliation errors. Just finality in seconds.
“This isn’t just faster payments — it’s a liquidity revolution,” Sun explains. “Capital that once sat idle for days can now rotate thousands of times per day.”
For global markets, this could unlock trillions in trapped capital — enabling new forms of lending, trading, and risk management.
FAQ: Understanding Blockchain’s Role in Finance
Q: Are stablecoins replacing traditional currencies?
A: Not yet. Most stablecoins are dollar-pegged and function as digital extensions of fiat money — not replacements. They enhance efficiency but operate within existing monetary frameworks.
Q: Can blockchain eliminate banks?
A: Unlikely in the near term. Banks provide credit creation, insurance, and customer service — functions beyond blockchain’s scope. However, blockchain may reduce their role in settlement and custody.
Q: Is “trustless” finance really possible?
A: Fully trustless systems remain aspirational. Even in DeFi, users trust code, oracles, and governance mechanisms. But blockchain minimizes reliance on human intermediaries — shifting trust from institutions to cryptography.
Q: Why do governments allow stablecoins?
A: Because compliant stablecoins strengthen the dollar’s global role. By holding U.S. Treasuries as reserves, issuers like Tether boost demand for American debt — aligning with national interests.
Q: Will blockchain make finance more secure?
A: It shifts risks. While smart contracts reduce counterparty risk, they introduce code vulnerabilities. The key is balancing decentralization with accountability — a challenge still being solved.
The Future: Coexistence Over Disruption
Blockchain isn’t waging war on traditional finance — it’s being absorbed by it.
Visa doesn’t need to become decentralized to benefit from stablecoins. DTCC doesn’t need to abandon custodianship to use distributed ledgers. The future isn’t “crypto vs. banks” — it’s hybrid finance, where:
- Traditional networks adopt blockchain for faster settlement
- Stablecoins become interoperable rails across payment systems
- Cryptographic tools enhance security and transparency
- Regulated innovation expands access and efficiency
The lesson from Libra’s fall and Visa’s adaptation is clear: lasting change works with existing systems, not against them.
As Sun Lelin puts it: “The next era of finance won’t be defined by revolution — but by evolution.”
