Problems solved by technology

Among them, in consensus mechanisms such as POW, POS, and DPOS, due to possible bifurcation, rollback, and reset operations of the blockchain, the new block may be replaced by other blocks, but the earlier the block is created, the faster the change. The greater the workload required in the future, the less likely it will be replaced. The possibility of replacing a certain number of previous blocks is basically gone. These blocks cannot be changed and are always stored on the blockchain.

Abstract

The embodiment of the invention discloses a blockchain system, a registration method and device, a cross-chain method and device. Information of a third-party block chain is registered, an irreversible block header of the third-party block chain is registered and an irreversible mathematical proof is provided, and data cross-chain of a transaction in the irreversible block is achieved by using the transaction, the block header of the block to which the transaction belongs, a Merkel proof of the transaction in the block to which the transaction belongs and the irreversible mathematical proof.Therefore, the irreversible block head can be identified without researching a third-party block chain in detail; irreversible mathematics prove that the cross-chain of the transaction data containedin the irreversible block of the third-party block chain can be easily realized, so that the cross-chain efficiency is improved.

Description

technical field [0001] This application relates to the technical field of blockchain, and in particular to a blockchain system, registration, and cross-chain methods and devices. Background technique [0002] With the development of information technology, blockchain technology has become a technology that people focus on due to its advantages of openness, non-tampering, and decentralization. Due to the decentralization of the existing blockchain technology, transactions executed in the blockchain need to be verified by each node in the blockchain before being stored in the blockchain (that is, on the chain). The corresponding transaction data (for example, the result after processing the transaction) is consensused. The consensus methods used in the existing blockchain technology mainly include proof of work (POW), proof of stake (POS), delegated proof of stake (DPOS), and practical Byzantine fault tolerance (PBFT). Among them, in consensus mechanisms such as POW, POS, an...
