The vision of building Hainan Free Trade Port (HFTP) into a "digital free trade zone" has been a strategic priority since its inception in 2018. As part of China's broader reform and innovation agenda, this initiative aims to establish Hainan as a new frontier for openness and technological advancement. In November 2019, the Ministry of Industry and Information Technology (MIIT) released A Plan to Support the Construction of Hainan Free Trade Zone and Free Trade Port with Chinese Characteristics, endorsing blockchain development, cross-border supply chain systems, and attracting leading enterprises to build a digital ecosystem in Hainan. This momentum was further strengthened in May 2020 when Hainan’s Department of Industry and Information Technology announced policies to accelerate blockchain innovation, including the creation of a blockchain industry fund worth 1 billion RMB and the establishment of a joint blockchain innovation platform.
This foundational push has laid the groundwork for blockchain to play a transformative role in international trade — one of the most promising domains for digital transformation within the Hainan Free Trade Port. As Brian Behlendorf, Executive Director of Hyperledger and a pioneer of the World Wide Web, once noted, the two most impactful areas for blockchain adoption today are supply chain management and trade finance.
In supply chains, blockchain enables end-to-end traceability, ensuring authenticity and transparency — exemplified by茅台 (Moutai)’s use of blockchain for product authentication. In trade finance, it facilitates secure interbank data exchange, multi-currency cross-border payments, and trustless settlement systems. Meanwhile, China's ongoing pilot testing of its central bank digital currency (DC/EP) is set to further catalyze blockchain integration across global trade operations.
This article explores how blockchain technology can drive the digital transformation of international trade in Hainan, examining real-world applications, technological benefits, and key legal considerations that must be navigated for sustainable growth.
Understanding Blockchain Technology
What Is Blockchain?
Although conceptual roots trace back to cryptographic research in 1991, blockchain emerged as a practical technology with Satoshi Nakamoto’s 2008 Bitcoin whitepaper. While often associated with cryptocurrencies like Bitcoin, blockchain itself is the underlying infrastructure — a decentralized peer-to-peer system that uses cryptographic hashing and consensus algorithms to securely record transactions across a distributed ledger.
Each block contains timestamped data linked through cryptographic hashes, forming an immutable chain. This structure ensures data integrity, transparency, and resistance to tampering — qualities highly valuable in international trade environments where trust and auditability are paramount.

Types of Blockchain: Public, Private, and Consortium
Early public blockchains like Bitcoin face limitations in scalability and privacy — critical concerns for enterprise use. To address these issues, three main types of blockchains have evolved:
- Public Blockchains: Open to all participants (e.g., Bitcoin, Ethereum). High transparency but lower transaction speed and privacy.
- Private Blockchains: Controlled by a single organization. Faster and more private but less decentralized.
- Consortium (or Permissioned) Blockchains: Governed by a group of trusted entities. Balances decentralization with performance — ideal for supply chains involving multiple stakeholders such as exporters, logistics providers, banks, and customs authorities.
For international trade applications in Hainan, consortium blockchains offer the optimal balance between security, efficiency, and regulatory compliance.
Evolution of Blockchain: From 1.0 to 3.0
Blockchain development can be divided into three evolutionary stages:
Blockchain 1.0: Digital Currencies
This era centers on cryptocurrencies. Two major categories exist:
- Sovereign Digital Currencies (CBDCs): Issued by central banks. China's DC/EP (Digital Currency/Electronic Payment) is a prime example — a state-backed digital yuan designed to replace physical cash using a two-tier distribution model (central bank → commercial banks → public).
- Non-sovereign (Private) Cryptocurrencies: Examples include Ripple’s XRP and Facebook’s former Libra project. These operate outside traditional banking systems, enabling fast cross-border transfers but raising regulatory concerns around money laundering and financial stability.
China has taken a cautious stance toward private cryptocurrencies: Bitcoin cannot be used as legal tender, ICOs are banned, and exchanges between Bitcoin and RMB are prohibited. However, DC/EP pilots are actively expanding across regions including Beijing-Tianjin-Hebei, the Yangtze River Delta, and the Guangdong-Hong Kong-Macao Greater Bay Area.
Blockchain 2.0: Smart Contracts
The launch of Ethereum in 2015 introduced smart contracts — self-executing code stored on a blockchain that automatically enforces agreement terms when predefined conditions are met.
Smart contracts eliminate intermediaries in processes like payment releases upon shipment confirmation or automatic insurance claims after customs clearance. Their potential spans trade finance, logistics coordination, and compliance automation.
Blockchain 3.0: Toward a Smart Society
Beyond finance and supply chains, blockchain converges with AI, big data, and IoT to support intelligent urban governance, digital identity systems, and transparent public services — aligning perfectly with Hainan’s ambition to become a fully integrated digital free trade port.
Why Blockchain Is Essential for Hainan’s Digital Trade Transformation
Hainan’s goal of becoming a global hub for digital trade requires overcoming longstanding inefficiencies in international commerce. Blockchain offers targeted solutions to core challenges.
1. Digitizing Ownership and Reducing Fraud Risk
Traditional international trade relies heavily on paper-based documentation — bills of lading, certificates of origin, invoices — which are slow to process, prone to loss or forgery, and vulnerable to fraud.
Take the bill of lading, a cornerstone of maritime shipping. It serves as proof of ownership and contract of carriage. Yet disputes over "delivery without original bill" or forged documents remain common.
Blockchain replaces physical documents with tamper-proof digital records. Each transaction — from order placement to delivery — is cryptographically secured and time-stamped. Ownership transfers are transparently logged, reducing disputes and enabling faster cargo release.
2. Building Trust Without Intermediaries
International trade involves numerous parties: exporters, importers, freight forwarders, insurers, banks, and government agencies. Each operates within siloed systems, leading to information asymmetry and coordination delays.
UN/CEFACT identifies three critical flows in global trade: goods, funds, and information. Trust among participants traditionally depends on third-party verification — banks vouching for payments, insurers underwriting risk, customs validating compliance.
Blockchain enables a shared source of truth. All authorized participants access the same real-time data without relying on intermediaries. When customs officials verify a shipment’s origin via blockchain-stored certificates, they do so instantly and securely.
Moreover, blockchain supports regulatory interoperability. Customs authorities across borders can securely share data while preserving sovereignty — accelerating clearance times and lowering compliance costs.

3. Enabling Faster, Cheaper Cross-Border Payments
Cross-border payments are notoriously slow and expensive. According to Accenture, global cross-border payment volumes grow at 5.6% annually and could reach $30 trillion by 2025. Yet traditional systems like SWIFT rely on correspondent banking networks involving multiple intermediaries, resulting in high fees (averaging $45–$55 per transaction), delays (often 3–5 days), and limited transparency.
Blockchain-based solutions bypass this complexity. For instance:
- In 2018, Ant Financial (Alipay), Standard Chartered Bank, and GCash completed the world’s first blockchain-powered remittance from Hong Kong to the Philippines — settling in 3 seconds and cutting costs by ~HK$500 per transaction.
- China Merchants Bank has developed a blockchain platform for cross-border settlements, improving reconciliation accuracy and reducing operational overhead.
Additionally, projects like the Jasper-Ubin initiative between Singapore’s MAS and Canada’s central bank demonstrated successful interbank transfers using Hashed Time-Locked Contracts (HTLCs) — smart contracts that ensure atomic swaps across different blockchain networks without counterparty risk.
Real-World Applications of Blockchain in Global Trade
Global Adoption Trends
Since 2017, governments and enterprises worldwide have piloted blockchain in trade:
- 2017: Monetary Authority of Singapore (MAS) and Hong Kong’s HKMA launched the Global Trade Connectivity Network (GTCN).
- 2018: Mexico, Peru, and Costa Rica built a blockchain-based Authorized Economic Operator (AEO) platform.
- 2018: Tianjin Port launched a blockchain pilot linking business, logistics, finance, services, and regulators.
- 2019: we.trade — a blockchain trade platform founded by 12 European banks — went live.
- 2019: U.S. Congressional Research Service published a report urging policymakers to explore blockchain’s impact on trade finance and customs.
Case Study: ATA Carnet Digitization
The ATA Carnet is an international customs document allowing temporary duty-free importation of goods (e.g., exhibition items). Issued by national chambers of commerce under World Customs Organization (WCO) rules, it traditionally relies on paper-based processes.
ICC’s World Chambers Federation developed Mercury II — an electronic system for issuing ATA Carnets — but adoption was hindered by trust issues among customs authorities regarding data integrity.
In 2017, the EU’s DG TAXUD partnered with ICC WCF to launch a blockchain proof-of-concept integrating Ethereum-based validation layers into Mercury II. The trial successfully demonstrated that distributed ledger technology could ensure data immutability, traceability, and cross-border trust, paving the way for full digitization.
Case Study: Cross-Border Remittances via HTLC
The Jasper-Ubin project showcased how HTLCs enable secure cross-chain payments:
- Bank A locks funds in a time-bound smart contract using a hash of a secret password.
- Bank B must provide the original password to unlock funds.
- Once revealed during settlement, the password triggers fund release on both ledgers simultaneously.
- If not claimed within the time window, funds revert automatically.
This mechanism ensures atomicity — either both transactions succeed or neither does — eliminating settlement risk without requiring mutual trust.
Using this method, a transfer of 105 SGD (at 1 SGD = 0.95 CAD) successfully delivered 100 CAD to the recipient within seconds — demonstrating scalability for future CBDC interoperability.
Legal Challenges in Blockchain-Based Trade
Regulatory Status of Digital Currencies
Regulatory approaches vary globally:
China
- DC/EP: Fully supported as legal tender; pilots underway.
- Bitcoin & Private Cryptocurrencies: Classified as "virtual commodities." Not legal tender; trading platforms banned; financial institutions prohibited from handling crypto-related services.
- Legal Protection: The Civil Code (Article 127) recognizes network virtual property rights. Courts increasingly uphold digital asset protections.
United States
No single regulator oversees crypto; responsibilities are fragmented:
- FinCEN: Enforces AML rules under the Bank Secrecy Act; requires crypto businesses to register.
- OFAC: Sanctions individuals/entities involved in illicit crypto activities (e.g., Venezuela’s Petro).
- CFTC: Treats crypto as commodities; regulates derivatives markets.
- SEC: Regulates tokens deemed securities; oversees exchanges and investment vehicles.
Legal Nature of Smart Contracts
Smart contracts are lines of code that execute automatically when conditions are met — but they are not legally binding contracts per se under most jurisdictions.
Key issues include:
- Lack of ambiguity resolution mechanisms
- No provisions for force majeure or renegotiation
- Difficulty interpreting code as intent
Therefore, smart contracts should be viewed as execution tools, not standalone agreements. They must be embedded within traditional legal frameworks — backed by written contracts specifying governing law, jurisdiction, remedies, and dispute resolution methods.
