QKI public chain, as one of the early public chain projects in China, 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 a long-term low price. In the future, the QKI public chain needs to seek breakthroughs in regulatory compliance, technical 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 the 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, achieving maximum transaction performance of 5000 transactions per second. This performance breakthrough mainly 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: Achieved reasonable resource allocation through intelligent matching rules, solving 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 block handling.
This technological architecture sharply contrasts with 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: Focused 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 the enhancement of transaction efficiency while maintaining decentralized 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 in 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 messenger and verifier roles, 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 regional fault tolerance.
Distributed Content Sharing: Based on a blockchain 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 field of green consumption is highly aligned with the "Implementation Plan for Promoting Green Consumption" issued 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: Adopting 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-consumption-settlement."
Dual Token Economic Model: Consumption points are pegged 1:1 to RMB for daily transactions; equity tokens represent governance rights in the system, allowing holders to participate in decision-making and gain 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 field of green consumption may still be in the exploratory stage.
2. Internet of Things and Smart Agriculture
The QKI public chain has significant potential for application in the Internet of Things and smart agriculture, but specific landing cases are few. 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 of 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 between 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 is not listed on mainstream exchanges, circulating only on self-built exchanges like QKSwap. Its staking mining mechanism claims to provide an annualized return of up to 24%, 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 (A, B, C levels and municipal agents), forming a distributed service network. Different levels correspond to different fees (ranging from 100,000 to 1,000,000) 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 fixed 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:
Too Low Circulation: The circulation rate is only 16.67%, far below the industry average.
Regulatory Pressure: Strict policies on virtual currencies in China have limited 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 lock 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 provide an annualized return of up to 24%, 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 combat domestic virtual currency-related activities will continue. The main regulatory challenges faced by the QKI public chain include:
Token Legality: Trading 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 cross-shard communication latency issues have 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:
User Growth Stagnation: 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 surpassed 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 token trading risks.
Differentiated Ecological Construction: Create vertical field applications (such as green consumption points and smart agriculture) to form a competitive advantage.
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 a long-term low price, 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, technical 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 excessive reliance on QKI coin and instead focus on enterprise-level blockchain services, such as supply chain management and data rights confirmation in compliance scenarios, exploring paths for technical implementation by participating 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.
