Blockchain technology is widely recognized for its potential applications across various sectors, including financial services, supply chain management, cultural entertainment, smart manufacturing, social welfare, and education. However, beyond technical challenges, its legitimate and compliant application involves complex economic and regulatory considerations.
Understanding the Token Paradigm in Blockchain
Two Interaction Models
From an economic perspective, most mainstream blockchain systems operate under two primary interaction models. Tokens, smart contracts, and consensus algorithms reside within the consensus boundary. Interactions occur both within the blockchain—such as recording external information on-chain—and externally, where tokens trade or correspond with off-chain assets or rights.
Trustless Token Transactions
Tokens are essentially state variables defined within the blockchain. They can be subdivided into smaller units based on uniform rules. Asymmetric encryption ensures token holder anonymity, and transfers between addresses are transparent, immutable, and independent of centralized trust institutions.
Three Consensus Concepts
Blockchain relies on three types of consensus: machine consensus (ensuring distributed ledger consistency), governance consensus (human-driven rulemaking), and market consensus (market-driven token valuation). Market consensus does not imply price stability but reflects supply-demand equilibrium.
Smart Contracts: Functions and Limitations
Smart contracts are self-executing codes that manage token operations on the blockchain. However, they face limitations: dependence on imperfect external data sources, inability to directly handle off-chain assets, and challenges in managing incomplete contracts with unanticipated exceptions.
Information Types and Trust
Blockchain stores both validated information (checked by nodes) and unvalidated data (added as transaction notes). Trust in blockchain stems from technological reliability (e.g., cryptographic proofs) and institutional frameworks, reducing reliance on traditional intermediaries.
Classifying Blockchain Applications
Token Economic Functions
Tokens serve four primary roles: as internal payment instruments, for purchasing external goods/services, providing equity-like returns, or representing off-chain assets/rights. These functions define key application directions for blockchain technology.
Tokenless Blockchain
Some applications use blockchain solely as a distributed or decentralized database, without leveraging tokens. For instance,京东 employs blockchain in supply chain management to enhance transparency and traceability.
Tokenized Assets
Tokens can represent real-world assets, improving registration and trading processes. This approach is particularly impactful in supply chain finance, where blockchain streamlines operations and reduces fraud.
Distributed Commerce
Blockchain enables decentralized autonomous organizations (DAOs), though widely successful cases remain elusive. Economically viable distributed business models are still emerging, focusing on scalable and sustainable implementations.
Blockchain and Financial Infrastructure
Account vs. Token Paradigms
Financial infrastructure traditionally relies on account-based systems (e.g., banking networks) or token-based systems (e.g., blockchain). Cash transactions require no trusted third party, while transfers involve intermediary account operations.
Tokenized Asset Transactions
Tokens facilitate asset representation and trading through strict rules: 1:1 asset backing, bidirectional convertibility, and audited reserve transparency. Centralized institutions often manage these processes to ensure credibility.
Comparative Analysis
Token and account paradigms can substitute or complement each other. Stablecoins (token-based) and third-party payments (account-based) share functional similarities but differ in underlying architecture. Hybrid models may emerge to leverage both approaches.
Central Bank Digital Currencies (CBDCs)
CBDCs represent electronic money issued directly by central banks. While prototypes exist, no major economy has fully launched a CBDC. These systems aim to maintain monetary stability during issuance and redemption.
Interbank Settlement and Cross-Border Payments
Projects like JPMorgan Coin use blockchain for instant interclient settlements. In cross-border payments, blockchain simplifies transactions, reduces liquidity costs, and extends accessibility—similar to initiatives like Facebook’s Libra (now Diem).
Post-Trade Processing
Blockchain can streamline securities settlement by replacing central securities depositories. Shared, synchronized ledgers reduce reconciliation needs and enhance efficiency, as demonstrated in DTCC’s proposed design for post-trade handling.
Analyzing Libra's Risks and Regulation
Operational Mechanism
Libra was designed as a synthetic currency unit backed by a basket of fiat currencies and invested in bank deposits and short-term government bonds. Revenue covered operational costs, ensured low fees, and distributed dividends to early investors. Users did not share investment returns.
Monetary Perspective
As a potential supranational currency, Libra faced challenges in achieving widespread adoption due to network effects and limited initial use cases for transactions and pricing. Its low fees promised financial inclusion but required market validation.
Key Risks
- Liquidity Risk: Aggressive investment strategies could impair the reserve pool’s ability to handle large-scale redemptions.
- Custodial Risk: Despite using investment-grade custodians, safeguards were necessary to meet regulatory standards.
- Cross-Bapital Flow Impact: Global regulatory scrutiny arose from potential effects on monetary sovereignty and financial stability.
- Monetary Policy Interference: Libra-based lending activities could influence money supply, necessitating oversight.
Compliance Challenges
Operating across multiple jurisdictions and currencies, Libra needed to comply with diverse national regulations, including anti-money laundering (AML) and securities laws.
Regulatory Considerations for Blockchain
Cryptocurrency Bubbles
Historical comparisons, such as the Mississippi and South Sea bubbles, highlight the speculative nature of cryptocurrencies like Bitcoin. Initial coin offering (ICO) mania peaked in 2017-2018 before regulatory interventions restored rationality.
ICO Issues
- Unclear Token Economics: Many ICOs offered tokens with ambiguous rights or utilities.
- Speculation: Secondary market trading often prioritized speculation over functional use.
- Incentive Misalignment: Project teams sometimes prioritized token sales over long-term development.
- Feedback Loops: Interdependencies between major cryptocurrencies (e.g., Bitcoin) and altcoins amplified market volatility.
Regulatory Responses
- Production and Primary Markets: Proof-of-Work (PoW) energy consumption sparked environmental debates. ICOs faced securities regulations, leading to security token offering (STO) and alternative trading system (ATS) frameworks.
- Circulation and Secondary Markets: Policies addressed investor suitability checks, market manipulation prevention, exchange security standards, taxation, AML protocols, and global coordination.

Frequently Asked Questions
What is the primary economic value of blockchain?
Blockchain reduces reliance on intermediaries by enabling trustless transactions and transparent record-keeping. It enhances efficiency in areas like supply chain tracking, financial settlements, and digital identity verification.
Can blockchain operate without cryptocurrencies?
Yes, tokenless blockchain applications use distributed ledgers for data management without monetary tokens. Examples include record-keeping systems in healthcare or public administration.
How do smart contracts handle real-world assets?
Smart contracts manage on-chain token transitions but require oracles to integrate off-chain data. They cannot directly control physical assets without supplementary legal and operational frameworks.
What are the biggest hurdles for CBDC adoption?
Technical scalability, privacy concerns, and interbank settlement integration pose significant challenges. Regulatory clarity and public trust are also critical for widespread adoption.
Why did Libra (Diem) face regulatory resistance?
Its global scale and potential impact on monetary sovereignty raised concerns among regulators. Compliance with multi-jurisdictional financial laws proved complex and ultimately limiting.
