Odaily recently came into contact with the blockchain project complex beauty, its research and development Chain33The underlying technology of blockchain is a developer platform based on parachain architecture.Currently open source. Developers can build public chains, alliance chains, and private chains on the platform.
One of the advantages of complex beauty is industrial application. At present, based on its technology, there are products such as the transfer of supply chain accounts receivable (enterprise IOUs), commodity on-chain, points, supply chain management, Internet of Things plus blockchain traceability, deposit certificates, wallets, and blockchain exchanges. According to CEO Wu Sijin, Fuzzy Beautys partners are mainly small and medium-sized enterprises, including large enterprises. for exampleA financial blockchain bill trading platform established with Midea，Hai Piao Hui, a blockchain bill trading platform established with HNA Horizon Linewait. Other cooperative units include Xiaomi, JD.com, Huawei Hangzhou Internet Court, etc.
In terms of core technology, the parachain architecture used by Complex Beauty is a bit like layer 2 in its underlying principles. For example, Wang Zhiwen, CTO of Complex Beauty, said that the parachain is very similar to the lightning network of Bitcoin, but it is different from the lightning network: the parachain will not generate state on the main chain, and the users on the parachain will only increase the data of the main chain content, does not add state content. Our data can be sharded on the main chain, and the state is not sharded. If there is a game running on the parachain, which is very popular and has a large number of users, the state of our main chain will not expand, and the data is also sharded. , all our transactions are through the main chain, and many parachains communicate through the main chain.”
Parallel chain Regarding the difference between parachain and sharding, Wang Zhiwen said that sharding and parachain are not exactly the same thing, but they try to solve the same problem: large-traffic transactions on the blockchain. The whole system of Complex Beauty Parachain is one chain, and the current technology of sharding is to divide it into many chains. The first version of Ethereum has not yet realized the cross-chain between chains, and the implementation of this solution will be very difficult. It involves sharding of state. The fragmentation of the state will cause very serious problems in the whole system, and the cooperation between the two chains will become very difficult.
Now the sharding in the industry is all data + state sharding, we are data sharding, not state sharding, so the implementation of the parachain will be much simpler. The parachain is more flexible and flexible. The parachain is only responsible for the calculation of business logic, which is assigned to the parachain. The data calculation results on the parachain are stored on the main chain. Security and consensus are guaranteed by the main chain. The status of the main chain Not fragmented.
In the field of blockchain, domestic large-scale Internet companies such as Tencent and Alibaba have established layouts. Compared with these companies, Wu Sijin said that Tencent and Alibaba currently only have layouts on alliance chains, but the complicated and beautiful layouts are on public chains, alliance chains, etc. On the chain, Complex Beauty is optimistic about the future development of the public chain.
At present, Complex Beauty has more than 200 employees, most of whom are technicians, and most of the employees come from companies such as Oracle, Alibaba, Hang Seng Electronics, and Dahua. Founder and CEO Wu Sijin, graduated from the Department of Financial Data Analysis and Finance of Zhejiang University, has many years of experience in software development and has been in business for 10 years. Co-founder and CTO Wang Zhiwen is good at exchange matching technology and cloud technology, and contributes codes to GO. In 2011, he began to study the Bitcoin code, and was familiar with the underlying technologies of mainstream blockchains such as Bitcoin, Ethereum, and BitShares. According to reports, Complex Beauty has applied for nearly 200 blockchain invention patents, ranking the worldsecondary title。
