Ex-chief Scientist Of Microsoft Research Group Joins Light Chain

LightChainLight Chain (LIGHT), designed to be the world’s first double-layer chain, announced that Leo Chen, a chief architect and a former chief scientist of the Microsoft Research Group of Asian Institutes, Li Huahong, a former senior architect from Qihoo 360, and Li Kun, a former senior architect from Microsoft Corp., have joined the core technology team.

These three big architects have led the development of a number of world-renowned large-scale data storage and processing systems. As the key science and technology forces in the industry, they are not only technologically experienced in JAVA, C++, irreversible algorithms, asymmetric encryption algorithms, Merkle trees, CAP theory and others, but also in project development and management.

What is Lightchain?

LightChain is different from all the blockchain technologies on the market. Light pioneers the double-chain technology composed of parent chain and child chain. This pioneering technology is created by a research and development group made up of more than 40 blockbhain experts and engineers through 3-year intensive research and hard works and is of epoch-making significance. It gives a revolutionary solution in view of the weakness of the existing blockchain technologies and also gives a solid technical foundation to the large-scale application of blockchain technologies in realistic scenarios.

The LightChain does not only reserve the core decentralized characteristics of the blockchain, but also further improves the transaction speed and guarantees security, which accordingly makes it greatly possible for the pilot application of LightChain in finance, insurance and other industries. It can thus be seen that the emergence of optical chains is expected to create a “value Internet” and promotes the entire economic system to achieve technological change, organizational change and efficiency change.

LightChain is a type of bottom chain technology, related to Blockchain, which perfectly solves the problem of low industry performance and TPS (transaction per second, i.e., the speed of handling requests) using the world’s first two-layer chain architecture. LightChain can achieve system performance of over 10wQPS and its emergence signifies the official entry into the millisecond transaction era of the blockchain industry. LIGHT network is composed by one prime-chain and numerous sub-chains.

Need for Light Chain

Currently, the Bitcoin transaction cycle is about 1-3 hours while the Ethereum transaction cycle is about 10 minutes, both of which would lead to the failure in realizing the “real-time handshake scenario”, meaning Blockchain is not able to be applied to the community on a large scale.

Under this context, in order to effectively maintain the core functions of Superbook, prevent records from being tampered with and destroyed, and achieve system performance above 10wQPS, a new revolutionary Blockchain – LightChain was established. LightChain will also bring the transaction speed into the millisecond era.

Scalability solution offered by Light Chain

LightChain is a two-layer chain technology, with one and only one prime chain, as well as one or more sub-chains independent of each other and arbitrarily expanding. Similar to the traditional public chain, the prime chain ensures that the records cannot be tampered with and destroyed and become transparent to the public, through distribution. Based on the Proof of Machine (PoM) validation method together with the In-Memory database cache, the performance of sub-chains are greatly improved.

The transaction record periodicity of sub-chains keep pace with that of the prime chain, such as 1 hour, 6 hours or 1 day, etc., to ensure that the prime chain has the complete transaction records of the entire network. The synchronization process is packaged through batch update. The records in the package have been checked in sub-chains, and thus the prime chain can update directly without checking.

LightChain also has a huge advantage in flexibility, and can be applied to all kinds of application scenarios.
