The QKI public chain, as one of China's early public chain projects, has gone through nearly 8 years of development and is facing a critical transformation period from technical exploration to industrial application. By November 2025, the QKI public chain has made significant progress in technological architecture innovation, with transaction processing capacity increasing from 7 transactions per second in the early stages to 5000 TPS, adopting a "consortium chain + public chain" hybrid architecture, integrating cutting-edge technologies such as sharding, anonymous transactions, and cross-chain mechanisms. However, its ecological construction is still in the initial stage, with a limited number of DApps, insufficient developer tool support, and ongoing pressure from China's strict regulatory policies. The market performance of QKI coin (QKI) is sluggish, not listed on mainstream exchanges, with a circulating market value close to zero and prices remaining low for an extended period. In the future, the QKI public chain needs to seek breakthroughs in regulatory compliance, technological implementation, and ecological expansion to achieve a qualitative change from "technical prototype" to "industrial application".
I. Technological Architecture and Performance Innovation#
1. Breakthrough in Sharding Technology: From 7 TPS to 5000 TPS
The core technological innovation of the QKI public chain lies in the realization of its dynamic sharding architecture. According to an academic paper published in April 2025 titled "Dynamic Sharding Model of Blockchain Based on Jump Hash and Asynchronous Consensus Group," QKI's sharding technology employs Jump Hash algorithm and asynchronous consensus group mechanism, enabling maximum transaction performance of up to 5000 transactions per second. This performance breakthrough primarily stems from the following technical optimizations:
Dynamic Sharding Strategy: Network sharding efficiency improved by 8% compared to Ethereum, with a 25% reduction in node migration workload when the number of shards dynamically increases or decreases.
Cross-Shard Transaction Optimization: Achieves reasonable resource allocation through intelligent matching rules, addressing the performance bottleneck of cross-shard transactions in traditional sharding technology.
User Self-Selection Mechanism: Allows users to choose which shard executes the transaction, enabling parallel processing of blocks.
This technological architecture stands in stark contrast to the QKI chain mentioned in 2020, which "broke through one million transactions within less than two years of mainnet launch," demonstrating substantial progress in performance optimization.
2. Hybrid Chain Architecture: Balancing Efficiency and Transparency
The QKI public chain adopts a hybrid architecture design of "consortium chain + public chain," with transaction clearing completed on the consortium chain, ensuring efficient compliance; key data synchronized to the public chain, ensuring transparency and auditability. This design allows it to meet the needs of different scenarios:
Consortium Chain Layer: Focuses on high-throughput transaction processing, capable of handling thousands of transactions per second, supporting smart contracts and Turing completeness, with fast transaction confirmation speed and low cost.
Public Chain Layer: Used for public verification and auditing of key data, ensuring data immutability and traceability.
This hybrid architecture aligns with the mainstream public chain technology trends of 2025, such as the "ubiquitous EVM layer" of the Akash public chain and the IBC protocol of Cosmos, both emphasizing improved transaction efficiency while maintaining decentralization characteristics.
3. Anonymous Transactions and Privacy Protection
The QKI public chain employs a combination of ring signatures and zero-knowledge proofs for privacy protection, achieving the characteristic of public transaction information while encrypting identities. This design protects user privacy while maintaining transparency of on-chain transactions, providing a technical basis for regulatory compliance:
Ring Signatures: Provide unconditional anonymity, making it impossible for verifiers to determine the identity of the signer.
Authorized Access Mechanism: Users must authorize access to sensitive data, balancing transparency and privacy protection.
Multi-Node Verification: Each node records a complete ledger, preventing single node failures or malicious attacks, enhancing system robustness.
4. Cross-Chain Mechanism: Innovative Design
The cross-chain mechanism of the QKI public chain introduces the roles of messenger and verifier, used for communication messages and transaction confirmations, respectively. This design draws on the characteristics of the TOR anonymous network, achieving a unique anonymous P2P communication network:
Pluggable Module Design: Encapsulates on-chain functions as pluggable modules, with area fault tolerance.
Distributed Content Sharing: A blockchain-based distributed content sharing network, enabling cross-chain asset interoperability.
Anonymous P2P Communication: Based on TOR network design, ensuring the anonymity of transaction paths.
II. Application Scenarios and Ecological Construction#
1. Green Consumption Points System
The application of the QKI public chain in the green consumption field aligns closely with the "Implementation Plan for Promoting Green Consumption" released by the National Development and Reform Commission and seven other departments in 2022. However, despite a favorable policy environment, the actual application cases of the QKI chain in the green consumption points system are still relatively limited. The main application scenarios include:
Points Issuance and Circulation: Uses a "minting-destruction" mechanism to maintain system balance, ensuring a constant total amount of points through smart contracts.
Coverage of Consumption Scenarios: Merchant terminals achieve points payment and real-time settlement through dedicated API interfaces, forming a complete closed loop of "recharge-consume-settle."
Dual Token Economic Model: Consumption points are pegged 1:1 to RMB for daily transactions; the rights token represents governance rights in the system, allowing holders to participate in decision-making and receive value-added benefits.
It is worth noting that the "Self-Discipline Declaration on the Application and Development of Green Consumption Points (Hangzhou)" released in August 2025 did not explicitly mention the QKI chain, indicating that its actual application in the green consumption field may still be in the exploratory stage.
2. Internet of Things and Smart Agriculture
The QKI public chain has significant application potential in the Internet of Things and smart agriculture, but specific landing cases are scarce. The 2025 smart agriculture technology report mentions blockchain technology application cases mainly based on Hyperledger or general technology frameworks, without explicitly using the QKI chain. Its technological advantages in the Internet of Things include:
Distributed Storage: Supports data storage for IoT devices through the QKFile distributed file system.
Data Rights Confirmation: Combines IoT and blockchain to achieve agricultural product traceability and data rights confirmation.
Device Interconnection: Supports trusted interactions among smart devices, reducing trust costs.
3. Exchange Ecology and Staking Mining
The QKI public chain has built an exchange ecology centered around QKSwap, providing value-added services such as staking mining and liquidity incentives, creating a one-stop service system of "trading + wealth management + ecology." However, QKI coin has not been listed on mainstream exchanges, circulating only on self-built exchanges like QKSwap. Its staking mining mechanism claims to offer up to 24% annualized returns but lacks third-party data verification.
4. Service Provider Network and Ecological Incentives
The QKI public chain has established a three-tier service provider network (levels A, B, C, and city-level agents), forming a distributed service network. Different levels correspond to different fees (ranging from 100,000 to 1 million) and profit-sharing ratios (1%-3.5%). This tiered system and profit-sharing mechanism aim to incentivize service providers to actively participate, but the actual effectiveness remains to be observed.
III. Market Performance and Value Positioning#
1. QKI Coin Market Performance is Sluggish
The market performance of QKI coin (QKI) has remained sluggish, not listed on mainstream exchanges, with extremely low trading volume. According to real-time data from November 2025, the 24-hour trading volume of QKI coin was only 0.01 USDT, with a circulating market value close to zero. Its historical price peak was 13.7 USD in October 2019, and the lowest point was 0.01 USD in December 2021, with current price data missing.
2. Value Positioning Contradiction
QKI was once positioned as "digital gold," emphasizing its constant total supply (21 million coins) and scarcity (only 3.5 million in circulation), but there is a clear contradiction between market performance and value positioning. On one hand, its dual token economic model attempts to establish a stable value anchor; on the other hand, market trading data is almost zero, lacking liquidity support. This contradiction mainly stems from:
Excessively Low Circulation: The circulation rate is only 16.67%, far below the industry average.
Regulatory Pressure: China's strict policies on virtual currencies have restricted the market circulation of QKI coin.
Insufficient Application Scenarios: Lack of large-scale application scenarios to support token demand.
3. Token Economic Model Execution Status
The token economic model of QKI includes two parts: total supply locking and mining rewards. In July 2019, the QKI public chain underwent a fork, halting output distribution, with only about 3.5 million QKI circulating in the market. Its staking mining mechanism claims to offer up to 24% annualized returns but lacks third-party data verification, and mainstream staking platforms have not listed QKI.
IV. Challenges and Future Development Directions#
1. Regulatory Compliance Challenges
China's regulatory policies on virtual currencies in 2025 continued the tone of "comprehensive prohibition of virtual currency trading," with Governor Pan Gongsheng clearly stating that efforts to crack down on domestic virtual currency-related activities will continue. The main regulatory challenges faced by the QKI public chain include:
Token Legality: Trading of QKI coin as a virtual currency within China is considered illegal financial activity.
Anonymity Risks: The anonymous transaction characteristics of QKI may be used for illegal activities such as money laundering.
Cross-Border Payment Restrictions: The cross-border capabilities of QKI conflict with China's foreign exchange control policies.
However, in 2025, China also launched a regulatory sandbox pilot, allowing testing of blockchain technology applications in specific scenarios. If the QKI public chain can focus on "technical applications" rather than token speculation, it may explore compliance paths by participating in the regulatory sandbox pilot.
2. Technical Implementation Challenges
Although the QKI public chain has made innovations in technological architecture, the actual application effects still need verification. The main technical challenges include:
Performance Stability: The performance improvement to 5000 TPS lacks empirical data support, and the cross-shard communication latency issue has not been fully resolved.
Application Scenario Adaptation: Existing application scenarios (such as green consumption points and IoT) have not yet formed a scale effect.
Developer Tool Support: Lack of comprehensive developer tools and documentation limits DApp development.
3. Ecological Development Challenges
The ecological development of the QKI public chain faces significant bottlenecks. The DApp report for the third quarter of 2025 shows that the QKI chain is almost blank in the DApp ecology, with mainstream public chains (such as Aptos, Sui, Solana, etc.) dominating. Specific challenges include:
Stagnation in User Growth: User growth for applications like Chain Letter (CCT) has not seen significant improvement.
Limited Number of Developers: The service provider network is tiered but actual application development is minimal.
Low Transaction Activity: Although on-chain transaction counts have exceeded 30 million, there is a lack of sustained growth momentum.
4. Future Development Directions
Based on the current development status, the future development directions of the QKI public chain may include:
Compliance of Technical Applications: Participate in regulatory sandbox pilots, focusing on compliance scenarios such as supply chain management and data rights confirmation.
Enterprise-Level Solutions: Develop customized blockchain services for enterprise clients to avoid risks associated with token trading.
Differentiated Ecological Construction: Create vertical field applications (such as green consumption points and smart agriculture) to form differentiated competitive advantages.
Cross-Chain Technology Optimization: Learn from cross-chain technologies of public chains like Akash to reduce cross-chain latency and enhance user experience.
V. Conclusion and Outlook#
As an early public chain project in China, the QKI public chain has made significant progress in technological architecture innovation, with transaction performance increasing from 7 TPS in the early stages to 5000 TPS, adopting a hybrid chain architecture to balance efficiency and transparency, combined with cutting-edge technologies such as sharding, anonymous transactions, and cross-chain mechanisms. However, its ecological construction is still in the initial stage, with a limited number of DApps, insufficient developer tool support, and ongoing pressure from China's strict regulatory policies.
The market performance of QKI coin is sluggish, not listed on mainstream exchanges, with a circulating market value close to zero and prices remaining low for an extended period, showing a clear gap with the value positioning of "digital gold." In the future, the QKI public chain needs to seek breakthroughs in regulatory compliance, technological implementation, and ecological expansion to achieve a qualitative change from "technical prototype" to "industrial application."
In the current regulatory environment, the QKI public chain may need to abandon its excessive reliance on QKI coin and instead focus on enterprise-level blockchain services, such as compliance scenarios like supply chain management and data rights confirmation, exploring paths for technological implementation through participation in regulatory sandbox pilots. At the same time, optimizing cross-chain technology, reducing latency, and enhancing user experience to attract more developers and users to participate in ecological construction.
Despite facing numerous challenges, the technological accumulation and early application experience of the QKI public chain still provide a foundation for its future development. If it can successfully transform into an enterprise-level blockchain service provider, the QKI public chain is still expected to play a certain role in China's digital economy and industrial digital transformation.
