for further convenience of explanation, a specific example of a simple cross-chain explanation is analyzed as follows:
in fig. 2, (a) is a conventional blockchain cross-chain technical architecture, and (b) is a novel cross-chain technical architecture diagram proposed by the present invention; in the method of the invention:
firstly, a user A applies for data cross-link transmission with a service provider B to a block chain technology platform;
the user A selects different function blocks on the block chain technology platform, namely different consensus mechanisms, such as a PoW consensus mechanism in the figure;
after the selection is completed, the block chain technology platform encapsulates the function block selected by the user A once, and the effect in the figure is a frame 1 surrounded by the PoW function blocks of the block chain layer;
the block chain technology platform packages the main network of the user node once, and the effect is a frame 2 on the way;
the block chain technology platform packages the functional blocks of the block chain layer of the user node and the main network layer together once, and the effect is that the block chain technology platform packages 3 times in the diagram until now;
user data A uploads the used block chain data to a block chain technology platform, and the block chain technology platform can carry out asymmetric decryption on the data, for example, a public key uses an MD5 method, and a private key uses an SHA256 method;
then, the block chain technology platform maps the data to the data layer of the user node, and packages the data layer once, and the effect is as shown in a frame 4 in the figure;
then, the data layer, the blockchain layer and the main network layer are encapsulated once by using the blockchain technology, the effect is as shown in a block 5 in the figure, and the data layer, the blockchain layer and the main network layer are encrypted by using non-heap encryption, such as an MD5 encryption method and an SHA256 encryption method, and are encapsulated five times;
meanwhile, service provider B also uses such five-time encapsulation, but its consensus mechanism is DPoS and TPS is 5000, while user a's consensus mechanism uses POW and TPS is 30;
by adopting an averaging method, TPS of a public consensus mechanism is set to be (5000+ 30)/2-2515 instead of the traditional chain-crossing method for obtaining the minimum value between the user A and the service provider B, so that the high efficiency is ensured;
meanwhile, the cross-chain method of the invention does not use the third-party intermediate service provider C, but adopts a public consensus mechanism PoX, the PoX comprises all the current block chain consensus mechanism types, and can be converted into any required type by a block chain technology platform, such as the PoW type of the user A;
when the intermediate service provider C adopted in the traditional chain crossing method carries out chain crossing, the off-line shutdown is carried out, the background operation is carried out, and the efficiency is very low;
the novel chain crossing method changes the common recognition mechanism DPoS of the service provider B into the common recognition mechanism PoW type of the user A, and the two chains utilize the same main network layer protocol, so that the chain crossing transmission speed is very high, and the seamless chain crossing effect can be basically realized;
after the cross-linking is completed, the cross-linking completion result is fed back to the blockchain platform of the user A, and the user A is led to the cross-linking end.
Obviously, the novel block chain crossing method for the integration of the homologous heterogeneous chain networks, which is provided by the invention, not only ensures that the transmitted information has higher fidelity in the process of crossing chains, improves the data security, has more robustness and the like; and moreover, high-efficiency value exchange and data migration can be realized, and seamless cross-chain tasks are completed.
