China international conference on block chain technology and application of the thunder chain technology upgrade attracted attention at home and abroad

In order to accelerate the application promotion of blockchain and promote the high-quality development of digital economy, the 2019 China blockchain technology and application conference with the theme of "focusing on technology-enabling entities" was held at shenzhen convention and exhibition center on April 10. Blockchain industry leader netheart technology was invited to attend the conference, netheart technology's xunlei chain chief engineer lai xin attended and announced the xunlei chain four technology upgrades: 1. 2. Take the lead in implementing the signature inverse public key algorithm in the national secret system, and reduce the storage space requirement in the national secret scenario; 3. Take the lead in realizing the revolutionary snapshot of storage in the industry, fundamentally reducing the storage pressure of nodes and improving the start-up speed of nodes; 4. Practical and feasible privacy protection plan. This series of technological innovations will greatly improve the development efficiency, lower the threshold of development, and further promote the block chain technology to empower the real economy, which has attracted high attention from all sectors of the industry.

Enabling entity into block chain development mission China's main chain leading the world into the 3.0 era

The 2019 China blockchain industry development report was released at the conference, which pointed out that blockchain, as a disruptive technology, is leading a new round of global technological and industrial changes.

The development level of China's main chain, represented by the thunderbolt chain, has occupied a leading position on the global stage. Lai xin, chief engineer of xunlei chain, said that in the year after xunlei chain was released, it has successfully served a number of real economy industries, providing them with block chain technology solutions, and supporting enterprises and industries to a higher level of development. At present, the actual scene application on the thunder chain has covered more than ten fields such as copyright, traceability, public welfare, insurance, travel and sharing economy.

In the process of the combination of block chain technology and real economy, the most critical constraint factor is whether the technical performance of the underlying main chain can meet the high requirements of the use scenario of real economy. Based on the practical experience of thunderbolt chain, there are four major challenges: performance, efficiency, storage and expansion.

To this, thunderbolt chain one by one to launch the corresponding technical solutions. Through the unique technology of isomorphic multi-chain framework, millions of TPS are realized, which can easily solve the problem of instantaneous high concurrency in large-scale commercial application scenarios, and realize nearly infinite super expansibility. At the same time, the innovative "DPoA+PBFT" consensus algorithm is used to realize the strong consistency of second level confirmation and distributed system, thus solving the efficiency problem. In addition, TCFS file storage system was released, which solved the problem of up-link storage of big data and large files, thus realizing the comprehensive support for large-scale commercial applications.

With innovative technology advantages, at present, thunderbolt have sprung up in the chain of quantum cloud yards, alpha lift, one foundation, turquoise, HGBC, traced the electricity science and technology, and other well-known industry application and case, these large scale users usage scenarios of the emergence of commercial grade application, marks the chain block industry development in our country has already entered the era of 3.0.

Xunlei chain four technical innovation to improve the development efficiency at home and abroad attention

At the conference, xunlei chain released four new technological innovations, first support EVM, WASM dual virtual machine mode, snapshot block chain storage innovation, support and optimization of national secret algorithm, as well as practical application of high feasibility of privacy protection scheme, to accelerate the block chain application development.

1. Support the further expansion of compatibility of dual virtual machines

In terms of extensibility, xunlei chain added a dual virtual machine system, on the basis of compatible EVM virtual machine, support WASM, thus realizing the intelligent contract in situ upgrade, no need to stop the interrupt service. At the same time, it also supports mutual invocation of contracts, so that developers can build and expand their own application ecology.

In addition, a new web development tool "Catalyst" is added, which does not need to be installed, comes with a demo template, and 0 threshold contract development, thus greatly accelerating block chain application development.

2. Support the state-secret algorithm to optimize the algorithm at the same time

In order to support the needs of more partners in cryptography algorithms, to ensure the security and reliability of cryptography algorithms, xunlei chain cryptography module has been upgraded. In addition to support international general cryptography algorithm can meet the support for the countries close algorithm, thunderbolt chain with profound technology accumulation in elliptic curve algorithm, designed the applicable Yu Guomi algorithm by the function of the inverse back public key signature, has realized the algorithm the optimization of the storage space under scenario, thus improve the whole efficiency of the chain block.

3. Cluster storage and snapshot compression storage are optimized

The thunderbolt chain abstracts the storage layer and ADAPTS a variety of storage engines to meet the requirements of different data volume scenarios. The industry took the lead in revolutionary realization of storage snapshot, fundamentally reduce node storage pressure, improve node startup speed and true lightweight accounting node.

4. Practical and feasible privacy protection scheme

According to users are most concerned about data privacy protection problem, thunderbolt chain intelligent contracts and cryptography will promise system used in combination, both protect the privacy of the participants' decisions and to ensure the participation on both sides of the fairness and participation, to achieve a real version of the "conflict resolution terminal", for better data privacy protection.

At present, China attaches great importance to the development and application of blockchain technology in the real economy. Driven by policies, technologies, markets and other forces, the pace of blockchain innovation is accelerating. Industry insiders said that the technological innovation of xunlei chain will further lower the development threshold of blockchain applications, play a catalytic role in developers to build phenomenon-level blockchain applications, thus accelerating the implementation of blockchain technology in the real economy, and play a crucial role in promoting the development of China's blockchain industry.
