Background
With the arrival of a new industrial revolution, the roles of new-generation information technologies such as cloud computing, big data, internet of things and the like in the industries of intelligent manufacturing, finance, energy, medical health and the like become more important. From the development trend at home and abroad and the block chain technology development evolution path, the development of the block chain technology and application needs a new generation of information technology industries such as cloud computing, big data, internet of things and the like as infrastructure support, and meanwhile, the block chain technology and application development plays an important role in promoting the development of the new generation of information technology industries.
The block chain technology is used as a novel decentralized protocol, transaction data can be safely stored, information cannot be forged and falsified, an intelligent contract can be executed, and auditing of any centralized mechanism is not needed. The transaction based on the blockchain technology can be digital currency, and can also be digital assets such as debt, equity, copyright and the like. The block chain technology solves the problem of the general of Byzantine, greatly reduces the trust cost and accounting cost of the real economy, and redefines the property right system of the Internet era. Essentially, the blockchain is a public ledger for recording all transactions which have occurred in the whole network, is a decentralized and distributed structure-contained data storage, transmission and certification method, and theoretically realizes self-certification of data in data transmission. This "decentralized" and "distrust" mechanism reduces the cost of establishing global trade "credits" in a more profound sense. Blockchain technology may reshape aspects of various monetary markets, payment systems, financial services, and economic modalities, which can fundamentally become a new paradigm for organizing activities to reduce friction and improve efficiency.
At present, common nodes of each block chain platform have respective consensus algorithms (such as POW, POS, and the like), but the consensus algorithms supported by different platforms have not been precedent for hooking communication protocols. How to provide a consensus communication protocol, which can simultaneously perform communication across platforms and solve the consensus problem becomes especially difficult for different blockchain technology platforms, the main difficulties are as follows: 1. the data calling interfaces of all the block chain platforms are inconsistent; 2. the intelligent contract languages of all block chain platforms are inconsistent; 3. the architecture and implementation method of each blockchain platform are inconsistent. At present, the prior art has no technology which can solve the problem.
