The term "virtual currency" broadly includes both cryptocurrencies and non-cryptocurrencies. In this context, we primarily focus on cryptocurrencies, such as Bitcoin, representing the narrow definition of virtual currencies. These digital assets, often created by individuals, companies, or other organizations, operate on decentralized networks.
Bitcoin, the first and most iconic virtual currency, was introduced in 2009 by an individual or group using the pseudonym Satoshi Nakamoto. It established a peer-to-peer decentralized financial system that revolutionized digital transactions.
How Virtual Currencies Work
Virtual currency transactions are recorded on a blockchain—a distributed ledger structured as a chain of data blocks. This technology uses cryptography to ensure immutability and prevent forgery, providing a secure foundation for transactions.
Within this system, accounts track transaction states and outcomes on the distributed network, while wallets store users' private keys. Since blockchain networks facilitate value transfer, protecting accounts, wallets, and transaction processes becomes critically important.
Types of Blockchain Wallets
Blockchain wallets vary based on how private keys are generated:
- Hardware wallets: Physical devices storing keys offline
- Software wallets: Applications storing keys on digital devices
- Custodial wallets: Third-party services managing keys
- Threshold wallets: Distributed key management systems
Legal Status and Property Attributes
China's current legal framework doesn't recognize virtual currencies as official currency, but acknowledges their property characteristics. Regulatory bodies often treat them as special virtual commodities rather than legal tender.
Judicial practice has seen courts affirming the property attributes of virtual currencies, suggesting they should be protected under property law frameworks. However, some legal scholars argue against classifying virtual currencies as "property," instead considering them as computer information system data. Certain criminal judgments have also recognized Bitcoin as computer system data.
Regulatory Perspective
Initially, regulators adopted an observatory approach toward virtual currencies before gradually implementing stricter measures. While virtual currency transactions face limitations, they aren't categorically illegal. These restrictions primarily aim to prevent speculative trading and maintain financial stability.

Dual Nature of Virtual Currencies
Similar to how a black car possesses both color and vehicle attributes, virtual currencies exhibit dual characteristics: they function both as property and as computer information system data. The view that virtual currencies possess only one of these attributes is fundamentally incorrect.
This dual nature creates complex legal and regulatory challenges that continue to evolve as technology advances and market practices develop.
Frequently Asked Questions
What defines a virtual currency?
Virtual currencies are digital representations of value that function as mediums of exchange, units of account, or stores of value. They typically operate on decentralized networks using cryptography for security.
How does blockchain technology secure transactions?
Blockchain creates an immutable, distributed ledger that records all transactions across a network of computers. Cryptographic principles ensure that once recorded, transactions cannot be altered or forged, providing transparent security.
Are virtual currencies legal?
Legal status varies by jurisdiction. While many countries don't recognize them as legal tender, most acknowledge their property attributes and allow regulated transactions with appropriate safeguards.
What's the difference between cryptocurrency and traditional currency?
Traditional currency is issued and regulated by central authorities like governments and banks. Cryptocurrencies operate on decentralized networks without central control, using cryptographic security instead of institutional backing.
Why are there different types of wallets?
Different wallet types offer varying security trade-offs. Hardware wallets provide enhanced security through offline storage, while software wallets offer greater convenience for frequent transactions.
How do regulators view virtual currencies?
Regulators typically focus on preventing financial crimes, protecting consumers, and maintaining monetary stability. Most approach virtual currencies with caution, implementing measures to prevent speculation while acknowledging technological innovation.
The evolving landscape of virtual currencies continues to present new challenges and opportunities for users, developers, and regulators alike. Understanding their fundamental nature provides crucial insight into their potential future development and integration into global financial systems.
