Chinese Name: 迅雷链

English Name: ThunderChain

Category: High-performance blockchain platform

Time of Release: April 2018


1.Handling millions of transactions per second

ThunderChain, based on Xunlei’s proprietary homogeneous multichain framework, is designed to be the first in the blockchain industry to realize confirmation and interaction among homogeneous chains and enable multiple transactions to be executed on different chains in parallel, making it possible to concurrently conduct millions of transactions per second (TPS).

Currently, Ethereum processes approx. 7-15 transactions per second while Visa processes around 5,000-8,000 transactions per second. By contrast, ThunderChain is capable of handling millions of transactions per second, supporting a much larger user base and a spectrum of application scenarios.

2.Fast and reliable confirmation in seconds

An optimized practical byzantine fault tolerance (PBFT) is adopted by ThunderChain as its consensus model which results in low latency and makes it possible to generate one block per second. PBFT, as a consistency algorithm, is able to avoid soft fork, ensuring stable operating performance.

3.Easy access and strong compatibility

ThunderChain supports smart contracts written in solidity language and is compatible with Ethereum Virtual Machine (EVM), making it easy to transfer applications from other blockchain platforms.

4.Resilient scalability in response to traffic bursts

The multichain structure is highly scalable, making it easy to handle greater concurrency when business is consistently expanding.  

5.Cost effectiveness and one-stop development solution

The fully-equipped blockchain underlying system is capable of performing all types of logic operations, significantly reducing the cost of application development and minimizing migration and maintenance, ultimately helping enabling developers saving operating costs.

6.Strength sharing to build the world’s leading blockchain ecosystem together with developers

ThunderChain creates a world’s leading blockchain ecosystem by leveraging Xunlei’s proprietary distributed technologies for decades, involving hundreds of millions of users and sharing more than a million active LinkToken holders.  


Along with the rapid evolution of big data, AI, 4K content and VR technologies, there is an unprecedented and explosive increase in the demand for computing resources such as CPU, bandwidth and storage. Meanwhile, Moore's Law, the driving force of declining cost of computing, is losing its power, resulting in sharp social contradictions.

Since 2014, Onething Technologies, a wholly owned subsidiary of Xunlei, has been exploring “shared computing” and views computing resources such as bandwidth, traffic and storage space as a source of productivity while the majority of such resources are not fully utilized in our daily life. Xunlei first launched Minecrafter, a smart device that helps Internet users share their idle bandwidth and storage space. Leveraging Xunlei’s proprietary technology, the shared resources are transformed into a giant cloud computing system. Xunlei describes the model as “the wave of cloud computing that everyone can participate in”.

In 2017, Xunlei released OneThing Cloud, an innovative smart device that not only provides more secure and faster personal cloud storage service but also helps users share idle computing resources. OneThing Cloud integrates the blockchain technology into shared computing model, exploring useful blockchain-based applications that create social value. The blockchain technology ensures an open, transparent and traceable process when users share their idle resources with companies, remarkably increasing efficiency and fairness and attracting an increasing number of users to participate in shared computing. Today, there are more than 1.5 million users involved in shared computing model, making OneThing Cloud a popular C-side blockchain application that provides actual benefit with customers.

ThunderChain is a vital part of Xunlei’s ongoing efforts to reshape the business world with shared computing and blockchain technology. When OneThing Cloud users enjoy storage and downloading services, they can voluntarily share their idle upstream bandwidth and storage space while rewarded with LinkToken. LinkToken is served as an incentive recording the amount of resources shared by the users. Xunlei’s StellarCloud and Nebula CDN make it possible to match idle resources with the needs of corporate customers, utilizing such resources in a meaningful, efficient and transparent way. During this process, corporate customers can benefit from cost saving through sharing idle resources and the individual users can get incentives. Currently, over one hundred corporate customers, including iQiyi and Xiaomi, benefit from such cost savings. ThunderChain not only provides a platform for blockchain developers to launch their products and services, but also expands the range of applicable scenarios for LinkToken. Corporate and individual developers can be rewarded with LinkToken by creating blockchain products and services. Corporate and individual developers can use LinkToken in exchange for StellarCoud services. Such value loop will help corporates and developers reduce costs.  


The ThunderChain has significant implications for driving the development of the blockchain sector. It addresses the performance and efficiency issues effectively and scales up the TPS capacity tremendously, making it possible to create blockchain applications in a spectrum of scenarios in real-life situations.  

It is widely believed in the industry that blockchain technology only creates value when combined with applications and business scenarios. However, there are concerns over whether blockchain networks are capable of meeting the needs of real-world use cases. For instance, Ethereum currently processes approximately 7-15 transactions per second while Visa processes around 5,000-8,000 transactions per second. Many business scenarios require hundreds of thousands or even millions of transactions to be processed per second. The differences in processing rates are one of the key factors hindering the wide adoption of the blockchain technology.

ThunderChain is poised to address the challenge. Leveraging a remarkable increase in the number of transactions processed per second, Xunlei’s super blockchain infrastructure ThunderChain meets the needs of many applications across industries and fully supports a variety of business scenarios including the public sector, healthcare, education, social apps, travelling, anti-counterfeiting, and copyright.

In addition to its superior performance, ThunderChain supports smart contracts for all types of logic operations with no additional servers required, significantly reducing the development cost and minimizing effort in migration and maintenance. All of these features save costs for users, expand the range of potential blockchain-based applications and promote the widespread adoption of the blockchain technology.

Blockchain 3.0

The blockchain technology is believed to bring about reform to the future of the global technology sector. Like Internet technologies in the 1980s, the emergence of blockchain-based applications at corporate level has already demonstrated its technological advantages and great potential. However, just like what Mail, Netscape and Gopher, the blockchain sector needs the deployment of large-scale applications that can be used by a large number of end users.

Bitcoin’s rise to popularity – largely due to its investment value – can be categorized as Blockchain 1.0. Ethereum’s adoption as a decentralized platform for a limited set of applications, is symbolizing as Blockchain 2.0. However, the scope of applications that can be run on Ethereum and other similar blockchain platforms is largely limited to content delivery. ThunderChain is categorized as a Blockchain 3.0 platform for a couple of reasons. First, with strong concurrent processing capability, it is remarkably different from Blockchain 1.0 and Blockchain 2.0 technologies. Meanwhile, ThunderChain’s high-performance blockchain solutions provide developers with a number of advantages, including cost saving, fast deployment of smart contracts and easy development of blockchain-based applications. In real business scenarios, ThunderChain is a powerful technology.  

The era of Blockchain 3.0 is believed to be marked by its integration into the real economy, real-world scenarios situations and widespread adoption. There are many so-called blockchain 3.0 products boasting of empowerment. However, these products remain basically in the in-basket and find it hard to justify themselves simply with a white paper. Xunlei’s ThunderChain has been deployed, and in the process of attracting more developers from China and overseas markets to develop and migrate blockchain applications. The real era of Blockchain 3.0 may have already come to us.
