Technical Field
The invention belongs to the technical field of block chain data processing, and particularly relates to a data processing method of a block chain.
Background
When data interaction is performed between the blockchain system and the blockchain system, the blockchain generally needs to have the capability of authenticating another blockchain data link so as to ensure the security of data transmission between the blockchain systems and prevent the data of the blockchain from being tampered.
There are many kinds of network implementations of cross-link, such as a wave card chain (Polkadot), which is a technology for implementing cross-link communication, and a verifier (Validator) is designed, and this role will check whether data comes from a blockchain (data authentication logic using the blockchain), and the Validator will use rights and interests to prove that a POS (Proof of stamp) algorithm agrees on the verification result, and the data that is agreed on can be confirmed to come from one blockchain, and another blockchain can use the cross-link data.
When the existing relay chain authenticates the cross-link data, the cross-link data need to be commonly identified through the POS of the relay chain, the throughput of the common identification algorithm of the relay chain is the upper limit of the cross-link data flow, and the upper limit bottleneck of the throughput exists. Meanwhile, when the block chain authenticates data on the relay chain, multiple signatures need to be verified, for example, POS needs to verify hundreds of signatures, and the execution efficiency is low.
