Public blockchains have become a foundational layer in the rapidly evolving digital economy, serving as decentralized platforms that support a wide range of decentralized applications (DApps). Among them, Ethereum (ETH) has emerged as the leading public blockchain, setting industry benchmarks in innovation, ecosystem diversity, and developer adoption. This article explores the structure, current landscape, challenges, and future trajectory of China’s public blockchain industry, with a focus on core technologies, market dynamics, and strategic developments.
What Is a Public Blockchain?
A public blockchain is a decentralized, permissionless distributed ledger accessible to anyone. It allows users worldwide to read data, send transactions, and participate in consensus mechanisms. Unlike private or consortium blockchains, public chains emphasize transparency, immutability, and collective maintenance—core attributes that underpin trust in digital environments.
In technical terms, public blockchains function similarly to operating systems like iOS or Android—they serve as the foundational infrastructure upon which DApps are built. These applications span gaming, finance, gambling, and prediction markets, creating a vibrant ecosystem driven by innovation and user engagement.
Major Public Blockchains: ETH, TRON, EOS
As of recent data, Ethereum (ETH), TRON, and EOS dominate the global DApp landscape, collectively capturing over 90% of market activity. Each chain exhibits distinct characteristics:
- Ethereum (ETH): Known for high decentralization and robust security, ETH leads in DApp diversity and transaction value. In 2019 alone, it processed $1.28 billion in transaction volume across more than 22 million transactions. Its ecosystem is strongest in financial and trading DApps, reflecting higher per-transaction value despite lower throughput (around 20 TPS).
- TRON: With over 420 million transactions in 2019 totaling $4.4 billion, TRON excels in scalability and user engagement. However, its DApp ecosystem is heavily skewed toward lottery and gambling applications—accounting for nearly 80% of transaction volume—indicating a user base focused on speculative activities.
- EOS: Offering fee-less transactions and higher throughput due to delegated proof-of-stake (DPOS), EOS recorded $6.1 billion in transaction value. While dominated by lottery-based apps, its active developer community fosters innovation in niche categories that could expand in the future.

Core Mechanisms: Consensus and Incentives
Two fundamental mechanisms govern public blockchains: consensus and incentive systems.
Consensus Mechanisms
Consensus ensures agreement across distributed nodes without centralized authority. The three primary models include:
- Proof of Work (POW): Used by Bitcoin and early Ethereum; secure but energy-intensive.
- Proof of Stake (POS): More energy-efficient but risks wealth concentration (the "rich get richer" effect).
- Delegated Proof of Stake (DPOS): Enables faster transactions via elected validators but reduces decentralization.
Each model presents trade-offs between security, speed, and decentralization—a challenge developers continue to address through hybrid or novel consensus algorithms like DSC (Dynamic Security Consensus) being explored by Penta Network.
Incentive Models
Incentives drive participation: nodes earn tokens for validating transactions or reporting malicious behavior. This model encourages network security and sustained node involvement, especially in competitive environments where validator roles offer financial rewards.
China’s Public Blockchain Industry Chain
The Chinese public blockchain ecosystem consists of three key segments:
Upstream: Infrastructure Providers
This includes:
- Mining equipment manufacturers such as Bitmain, Canaan Creative, and Ebang International—collectively controlling over 90% of global mining hardware supply.
- Server providers like Huawei, Inspur, and H3C dominate domestic data infrastructure.
- Cloud service platforms including Alibaba Cloud, Tencent Cloud, and AWS support remote computing needs for blockchain projects.
These components form the backbone of blockchain deployment, particularly for POW-based networks requiring significant computational power.
Midstream: Blockchain Developers
Developers invest heavily in three areas:
- Infrastructure (15%): Servers and cloud resources.
- Human resources (50%): Skilled engineers make up ~80% of most teams.
- Marketing (30%): Essential for attracting users and DApp creators.
Leaders in this space include both established chains and emerging innovators focused on improving performance and usability.
Downstream: Ecosystem Participants
Key players include:
- DApp developers, mostly building on existing public chains.
- Exchanges like Binance and Huobi facilitate token trading.
- Media outlets such as Jinse Finance and ChainDD provide education and market insights.
- Users, predominantly male aged 26–39, often motivated by speculation or technological curiosity.
DApp usage is dominated by gambling (32.5%), followed by finance (12.5%), games (11.5%), and risk-based applications (10.1%).

Market Size and Growth Projections
China’s public blockchain market grew at a staggering 292.8% CAGR from 2015 to 2019, expanding from $1 million to $2.39 billion. This surge was fueled by rising DApp adoption post-CryptoKitties (2017) and increasing venture capital interest.
Looking ahead, the market is projected to grow at 31.9% CAGR, reaching $9.5 billion by 2024. Factors driving growth include:
- Improved transaction speeds
- Lower user entry barriers
- Advancements in cross-chain interoperability
In 2019, ETH led with 54% market share ($1.29B), followed by EOS (27.2%) and TRON (18.8%), highlighting ETH's dominance in value creation and developer trust.
Industry Challenges
Despite rapid growth, several pain points hinder scalability and trust:
1. "Air Coins" and Fraudulent Projects
Approximately 80% of public chains are inactive "zombie chains", created solely to issue worthless tokens ("air coins") without real-world utility. Developers often exit after inflating prices—posing severe risks to investors.
2. Lack of Innovation
Due to open-source nature, many chains copy existing codebases with minimal differentiation, resulting in homogenized ecosystems lacking competitive advantages.
3. Poor Computational Performance
As node count increases, so does network congestion. For example, Ethereum’s 20 TPS limit causes delays during peak usage. Scaling solutions like sharding and Layer-2 protocols are critical to overcoming these bottlenecks.
Regulatory Environment in China
The Chinese government supports blockchain technology while strictly regulating cryptocurrency speculation:
- Encourages innovation in secure, high-performance public chains.
- Bans ICOs and trading platforms to prevent financial risks.
- Promotes enterprise-grade blockchain use cases in supply chain, finance, and data sharing.
This balanced approach fosters responsible development while curbing speculative excesses.
Future Trends Shaping the Industry
1. Optimized Consensus Algorithms
Next-generation consensus models aim to balance decentralization, security, and efficiency. Projects like Penta’s DSC algorithm represent steps toward scalable yet secure networks.
2. Cross-Chain Interoperability
With thousands of isolated blockchains, cross-chain technology is essential for asset transfer and data sharing between ecosystems. Current methods face hurdles:
- Verifying external transaction authenticity
- Preventing double-spending
- Ensuring consistency across different consensus rules
Emerging solutions may combine notary mechanisms with relay chains and parallel chains, enabling seamless inter-chain communication.
