How Blockchain Is Transforming Industries: Insights from Tencent’s 2019 Whitepaper

Policy Support and Market Growth

Since blockchain was first listed as a strategic frontier technology in December 2016, the Chinese government has issued a series of national and local policies, with 25 provinces releasing blockchain‑related regulations by June 2019. This policy backing has accelerated research, standardization, and industrialization, leading to a rapid increase in blockchain companies—growth rates exceeding 250% for two consecutive years.

Industry Ecosystem Formation

The whitepaper identifies three emerging layers in the blockchain ecosystem: infrastructure, industry applications, and comprehensive services. Blockchain is moving beyond digital currencies to fuse with various sectors, providing new momentum for industrial upgrades.

Investment Trends

Investment in blockchain has shifted from primarily financial backing to a growing share of strategic investment, rising from under 10% in 2015 to 24.38% in 2018. While early‑stage projects still dominate funding, the proportion of later‑stage financing is expected to increase, fostering deeper industry innovation.

Patent Landscape

Global blockchain patent filings have risen steadily, though the growth rate has slowed from a 3000% surge in 2015 to about 40% in 2018. China’s share of new patents grew from 33.33% in 2014 to 82.1% in 2018, driven by strong policy emphasis and corporate investment.

Blockchain Integration with Traditional Industries

In the early stage of industry‑blockchain convergence, the most common demand is trust enhancement, realized through data notarization (storage and certification). Notarization improves data credibility across judicial, financial, public welfare, government, copyright, medical, traceability, and supply‑chain domains, laying the foundation for broader applications such as identity authentication, data exchange, and asset trading.

Blockchain in Financial Services

Blockchain’s traceability, immutability, and smart‑contract automation address high costs in credit assessment, settlement inefficiencies, risk control, and data security. By tokenizing assets and enabling on‑chain/off‑chain asset flow, blockchain improves liquidity and reduces information asymmetry between finance and real‑economy sectors.

Tencent’s Blockchain Practices

Tencent has pursued blockchain since 2015, focusing on infrastructure (TrustSQL) and platform services (TBaaS). TrustSQL, the proprietary blockchain platform, has evolved to a three‑layer architecture with expanded core services, contract management, and vertical industry solutions. TBaaS, built on open‑source projects such as Hyperledger Fabric, FISCO‑BCOS, and TrustSQL, offers a one‑stop cloud service that supports use cases in insurance, settlement, e‑invoicing, supply‑chain finance, smart healthcare, and charitable initiatives.

Key Deployments and Outcomes

Electronic invoicing platform "Tax Chain" issued over 600 000 invoices worth ¥3.9 billion across 113 industries.

Supply‑chain finance solution "Micro Enterprise Chain" secured ¥100 billion financing and received a no‑objection letter from the Shenzhen Stock Exchange.

Judicial notarization platform "ZhiXin Chain" integrated with China Mobile’s mobile court system, storing over ten million records on‑chain.

City‑bank bill settlement network deployed 48 nodes, processing ~200 bills daily and mitigating market risk.

Future Outlook

Blockchain is expected to further strengthen the transition from an information‑centric internet to a value‑centric ecosystem, driving both traditional industry upgrades and financial innovation. Tencent plans to continue enhancing core infrastructure, expanding vertical solutions, and promoting open‑shared development to accelerate the adoption of industry blockchain over the next three to five years.
