Public blockchain technology has emerged as a foundational force in the digital economy, serving as a decentralized infrastructure that enables trustless transactions and innovative applications. Among global public chains, Ethereum (ETH) stands out as the largest and most influential network, driving advancements in decentralized applications (DApps), smart contracts, and blockchain scalability. This article explores the structure, market dynamics, challenges, and future trends of China’s public blockchain industry, offering a comprehensive view of its ecosystem and growth trajectory.
Understanding Public Blockchains: Definition and Classification
Blockchain is a distributed ledger technology secured by cryptography, ensuring data immutability and transparency. It operates on three primary models: public blockchains, private blockchains, and consortium blockchains. Public blockchains are open to all—anyone can read, send transactions, and participate in consensus without permission.
Think of public blockchains as operating systems like iOS or Android—foundational platforms upon which decentralized applications (DApps) are built. These networks power a growing digital economy, with ETH, TRON, and EOS leading in DApp deployment, user engagement, and transaction volume.
As of 2019, these three chains dominated over 90% of the global DApp market. Ethereum led in total transaction value at $1.28 billion, with 22.4 million transactions. While ETH boasts high decentralization and diverse DApp categories—especially in gaming and finance—its limitations include high gas fees and low throughput (around 20 transactions per second).
TRON reported 420 million transactions worth $440 million, largely driven by gambling and lottery-based DApps. Notably, 79.7% of TRON’s transactions were from lottery apps, contributing 90.4% of its transaction volume.
EOS processed over 1.1 billion transactions totaling $610 million. With no user fees and an active developer community, EOS supports a wide range of experimental DApps. Though only 2.6% of its revenue comes from non-gambling apps, their transaction volume accounts for 34.1%, indicating strong innovation potential.

Core Mechanisms: Consensus and Incentives
Two fundamental mechanisms underpin public blockchains: consensus and incentive models.
Consensus ensures agreement across distributed nodes. The main types include:
- Proof of Work (PoW): Secure but energy-intensive.
- Proof of Stake (PoS): More efficient but risks wealth concentration (the "Matthew effect").
- Delegated Proof of Stake (DPoS): Faster but relies on voter participation, which can be low.
Incentive mechanisms reward nodes for validating transactions or reporting malicious activity. These rewards encourage participation and enhance network security, forming the economic backbone of decentralized systems.
China’s Public Blockchain Industry Chain
The industry ecosystem consists of three layers:
Upstream: Infrastructure Providers
This includes hardware and cloud service providers essential for blockchain operations.
- Mining Equipment: Companies like Bitmain, Canaan Creative, and Ebang International dominate global mining hardware production, controlling about 90% of network hash power.
- Servers: Huawei, Inspur, and H3C lead China’s server market (62.8% share), providing physical computing resources.
- Cloud Services: Alibaba Cloud, Tencent Cloud, Huawei Cloud, AWS, and China Telecom’s Tianyi Cloud occupy over 60% of China’s public cloud market—critical for scalable blockchain development.
Midstream: Blockchain Developers
These are the builders creating public chains. Their costs break down as follows:
- 50% on talent: Development teams average 20 members, with 80% being engineers.
- 30% on marketing: Essential for attracting developers and users.
- 15% on infrastructure: Servers and cloud usage.
Leaders like ETH attract top talent and investment, while emerging chains focus on niche improvements in speed or usability.
Downstream: Applications and Users
Key players include:
- DApp Developers: 90% use public chains as base layers. Most DApps fall into gaming (11.5% users), finance (12.5%), gambling (32.5%), and speculative apps (10.1%).
- Exchanges: Platforms like Binance facilitate token trading and liquidity.
- Media Outlets: Golden Finance, Bitmain’s BaBit, ChainNews, and DAppReview provide education, analytics, and promotion.
User demographics show a male-dominated base (80%) aged 26–39, primarily motivated by speculation. However, 10% are tech enthusiasts ("geeks") who believe in blockchain’s long-term utility.
Market Size and Growth Trends
China’s public blockchain market grew from $0.1 billion in 2015 to $23.9 billion in 2019—a compound annual growth rate (CAGR) of 292.8%. This surge was fueled by the rise of DApps following milestones like CryptoKitties in 2017.
Looking ahead, the market is projected to grow at a CAGR of 31.9%, reaching $95 billion by 2024—driven by improved performance, lower entry barriers, and cross-chain interoperability.
In 2019, ETH captured 54% of the market ($12.9 billion), followed by EOS (27.2%, $6.5 billion) and TRON (18.8%, $4.5 billion).

Key Challenges Facing the Industry
Despite rapid growth, several pain points persist:
Air Token Proliferation
Many projects issue "air tokens"—digital assets without real-world utility or active development—purely to speculate and exit early. Up to 80% of public chains are inactive ("zombie chains"), posing significant risks to investors.
Lack of Innovation
Due to open-source codebases, many new chains copy existing architectures with minimal differentiation, leading to homogenized offerings.
Poor Performance
As node count increases for greater decentralization, network congestion rises. Every node must validate every transaction, slowing processing times. Ethereum’s TPS remains below 20—a bottleneck for mass adoption.
Regulatory Environment in China
The Chinese government supports blockchain innovation but strictly prohibits cryptocurrency speculation ("coin炒作"). Policies emphasize:
- Enhancing computational efficiency and security.
- Protecting users’ digital assets.
- Discouraging illegal fundraising via ICOs.
This balanced approach fosters responsible development while curbing financial risks.
Future Outlook: Where Is the Industry Headed?
Optimized Consensus Mechanisms
Developers are exploring hybrid algorithms that balance decentralization, speed, and security. For example, Penta Network’s DSC consensus aims to improve scalability without sacrificing trustlessness.
Cross-Chain Technology Advancement
With thousands of isolated blockchains today, interoperability is crucial. Cross-chain solutions aim to:
- Accurately relay data between chains.
- Prevent supply inflation during asset transfers.
- Ensure consistent transaction outcomes across networks.
Current approaches like notary schemes suffer from low efficiency. The future may see hybrid models combining notaries for custody and relay chains for verification—enabling secure multi-chain interactions.
Frequently Asked Questions (FAQ)
Q: Why is Ethereum considered the leading public blockchain?
A: Ethereum offers robust smart contract functionality, a mature developer ecosystem, and widespread DApp adoption across finance, gaming, and NFTs—making it the most versatile and widely used public chain.
Q: What are the main differences between PoW, PoS, and DPoS?
A: PoW uses computational power to secure the network (e.g., Bitcoin), PoS selects validators based on staked coins (more energy-efficient), while DPoS allows token holders to vote for delegates—offering speed but less decentralization.
Q: How do public blockchains generate revenue?
A: Revenue comes from transaction fees (e.g., gas on ETH) and token issuance. Developers may also earn through ecosystem grants or staking rewards.
Q: Are all Chinese blockchain companies based in China?
A: No—many have relocated headquarters overseas due to regulatory pressures but maintain R&D or infrastructure operations within China.
