Since its establishment in 2018, transforming Hainan Free Trade Port (FTP) into a "Digital Free Trade Port" has been a key initiative to deepen reforms, foster innovation, and expand openness. On November 9, 2019, China’s Ministry of Industry and Information Technology (MIIT) released the Implementation Plan for Supporting Hainan’s FTP Development, advocating blockchain adoption, cross-border supply chain systems, and partnerships with leading blockchain firms to build "Digital Hainan." By May 2020, Hainan’s Department of Industry and Information Technology introduced policies to accelerate blockchain innovation, including a 10 billion yuan blockchain industry fund and the "Chain+Hainan" ecosystem.

Against this backdrop, blockchain’s role in international trade is pivotal for Hainan’s digital transformation. As noted by Hyperledger Executive Director Brian Behlendorf, blockchain’s primary applications are supply chain management and trade finance:

This article explores blockchain’s potential in international trade, practical applications, and legal considerations, structured into four parts:

  1. Blockchain Basics: Concepts, classifications, and evolution.
  2. Blockchain’s Role in Trade Digitalization: Trust-building, efficiency, and security.
  3. Real-World Use Cases: ATA Carnet digitization and cross-border payments.
  4. Legal Issues: Cryptocurrency regulation and smart contracts.

Part 1: Understanding Blockchain

1. What Is Blockchain?

Born from 2008 Bitcoin whitepaper by Satoshi Nakamoto, blockchain is a decentralized ledger using cryptographic hashes to ensure data immutability. Unlike Bitcoin (a blockchain application), the technology itself supports diverse uses.

2. Blockchain Types

| Type | Definition | Use Case |
|------------|-------------------------------------|------------------------------|
| Public | Fully transparent (e.g., Bitcoin) | Open cryptocurrencies |
| Private | Restricted access (e.g., audits) | Internal corporate systems |
| Consortium | Multi-organization control (e.g., Hyperledger) | Industry collaborations |

3. Blockchain’s Evolution


Part 2: Blockchain’s Value for Hainan FTP

1. Digital Proof of Ownership

Replaces paper-heavy processes (e.g., bills of lading) with tamper-proof records, reducing fraud risks.

2. Trust Mechanism

Simplifies compliance via shared data among traders, banks, and customs (e.g., WTO’s Trade Facilitation Agreement cuts costs by 14.3%).

3. Efficient Payments

Enables real-time, low-cost cross-border transactions (e.g., Ant Group’s 3-second Hong Kong–Philippines transfers).


Part 3: Blockchain Applications

1. Global Projects

2. Case Study: Jasper-Ubin Project

A Canada-Singapore initiative using hashed timelock contracts (HTLC) for instant, multi-currency settlements.


Part 4: Legal Challenges

1. Cryptocurrency Regulation

2. Smart Contracts

Lack traditional legal enforceability; disputes require conventional contract law.


FAQs

Q1: How does blockchain prevent fraud in trade documents?
A: By creating immutable, timestamped records (e.g., ATA Carnets).

Q2: Is Hainan’s blockchain fund accessible to foreign firms?
A: Policies encourage global partnerships, but compliance with local laws is essential.

Q3: Can smart contracts replace lawyers?
A: No—they automate execution but can’t handle complex legal interpretations.
