What Are Cryptocurrency, Blockchain, and Crypto Assets?

·

In the late 1990s, Kevin Werbach—a renowned expert on internet and communication technologies, associate professor at the Wharton School, and former advisor at the U.S. Federal Communications Commission—witnessed the rise of the dot-com boom. Today, he’s turning his attention to one of the most transformative technological shifts of our time: blockchain and its related innovations.

Werbach’s upcoming book, The Blockchain and the New Architecture of Trust, set to release in November 2025, dives deep into how decentralized systems are reshaping trust in digital economies. In a widely shared article on Medium, he clarifies a common source of confusion in the tech world: the conflation of cryptocurrency, blockchain, and crypto assets. While these three concepts share foundational technology, their purposes, use cases, and implications differ significantly.

To make sense of this landscape, Werbach introduces the "3T Framework": Trust-minimizing, Tracking, and Trading. These principles help distinguish between the three branches and reveal how each is uniquely shaping the future of digital interaction.

Cryptocurrency and Trust-Minimizing

At the heart of the cryptocurrency movement is a radical idea: you don’t need to trust anyone to conduct secure transactions. Bitcoin, the most well-known cryptocurrency, exemplifies this principle. Rather than focusing on mining or digital cash mechanics, Werbach urges us to see Bitcoin as a system designed to minimize trust.

Traditionally, financial transactions rely on intermediaries—banks, payment processors, or governments—to verify legitimacy. These centralized institutions act as trusted third parties. But centralization comes with risks: institutions can fail, be hacked, or act maliciously.

Cryptocurrencies solve this by using cryptographic proof and decentralized networks to validate transactions. In this model, trust isn’t placed in people or organizations, but in code, consensus algorithms, and network incentives. As long as the system functions correctly, users gain the benefits of trust—security, finality, and ownership—without relying on any single entity.

However, this trust-minimizing approach isn’t free. Bitcoin’s proof-of-work mechanism, for instance, demands massive computational power and energy consumption. Additionally, maintaining a decentralized miner community requires ongoing coordination and economic incentives. The cost of decentralization must be weighed against its benefits.

Still, the core innovation remains powerful: a system where value can be transferred globally without intermediaries, opening doors to financial inclusion and censorship-resistant transactions.

Blockchain and Tracking

While often linked to cryptocurrency, blockchain technology has a broader application: tracking data across untrusted parties. Unlike cryptocurrency’s goal of eliminating trust, blockchain often works by reducing uncertainty within semi-trusted environments.

Imagine a global supply chain: manufacturers, shippers, distributors, and retailers all handle the same product but maintain separate records. Discrepancies arise. Delays follow. Costs climb. According to industry estimates, companies spend nearly $10 trillion annually on logistics, much of it tied to inefficiencies in information sharing.

Blockchain addresses this by creating a shared, immutable ledger. Each party records transactions on the same distributed database. No one needs to fully trust the others—because the system ensures transparency and auditability. If every participant can verify the history of a product—from raw materials to final sale—errors decrease, fraud becomes harder, and efficiency improves.

Werbach emphasizes that this isn’t about total decentralization. Many enterprise blockchains are permissioned, meaning only authorized entities can participate. The goal isn’t to remove trust entirely but to optimize it through verifiable data trails.

This makes blockchain ideal for applications like:

In short, blockchain excels where traceability and accountability matter more than anonymity or decentralization.

Crypto Assets and Trading

If cryptocurrency is about transferring value and blockchain is about tracking information, then crypto assets are about financialization—turning digital tokens into tradable instruments.

A crypto asset is any digital token that holds economic value and can be bought, sold, or exchanged. This includes not just cryptocurrencies like Bitcoin and Ethereum, but also stablecoins, non-fungible tokens (NFTs), security tokens, and utility tokens.

The key distinction? Crypto assets treat tokens as investment vehicles, not just tools for payment or access. They exist within ecosystems powered by blockchain but are primarily used for speculation, yield generation, or portfolio diversification.

For example:

What’s unique is that these assets are natively digital and globally accessible. Unlike traditional securities, they can be traded 24/7 across borders with minimal friction. However, this also brings volatility and regulatory uncertainty.

Importantly, crypto assets depend on underlying cryptocurrencies. You can’t trade a token unless there’s a network to validate and settle the transaction. Yet for many traders, trust in the system is secondary to liquidity and returns—trust becomes a means to enable trading, not an end in itself.

Frequently Asked Questions

Q: Are blockchain and cryptocurrency the same thing?
A: No. Cryptocurrency is a type of digital money that uses blockchain technology, but blockchain has many other uses—like supply chain tracking or identity verification—that don’t involve currency.

Q: Can blockchain work without cryptocurrency?
A: Yes, especially in private or enterprise settings. Permissioned blockchains used by corporations may not require a native cryptocurrency to function.

Q: What makes crypto assets different from traditional investments?
A: Crypto assets are built on decentralized networks, enabling borderless, always-on trading. They often offer new financial mechanisms like staking or liquidity mining, but come with higher volatility and regulatory risks.

Q: Is decentralization always better?
A: Not necessarily. While decentralization enhances security and censorship resistance, it can reduce efficiency. The right balance depends on the use case.

Q: Can blockchain eliminate fraud entirely?
A: Blockchain makes tampering extremely difficult due to immutability, but it doesn’t prevent fraudulent activities at the application level—like scams or fake ICOs.

Q: Why do people say blockchain rebuilds trust?
A: Because it replaces reliance on human institutions with transparent, verifiable systems. Even if parties don’t trust each other, they can trust the data recorded on the blockchain.

Final Thoughts

As Werbach wisely notes, the success or failure of one branch doesn’t determine the fate of the others. Just because some initial coin offerings (ICOs) turned out to be scams doesn’t mean blockchain lacks potential. Conversely, widespread enthusiasm for blockchain doesn’t guarantee its widespread adoption.

Each component—cryptocurrency (trust-minimizing), blockchain (tracking), and crypto assets (trading)—must be evaluated on its own merits. Understanding their differences allows us to cut through hype and focus on real-world utility.
