A data verification and sending and receiving method, node and system for connecting parallel links to interconnected chains

Abstract

The invention discloses an interconnected chain system structure (including: a data verification method for parallel links entering the interconnected chain, a data sending and receiving method for parallel links entering the interconnected chain, an interconnected chain, a parallel chain, a data verification node, and a data sending and receiving node). The method includes: the data verification node receives an access request for connecting the parallel link to the interconnection chain sent by the data sending and receiving node of the parallel chain; in response to the access request, the data verification node generates identification information including at least the first consensus algorithm, and stores the identification information , and broadcast the identification information in the interconnection chain; after the data verification node confirms that at least one other verification node in the interconnection chain has received the identification information, it feeds back access success information including the identification information to the data sending and receiving node. The embodiment of the present invention can synchronize information, which not only improves the security of accessing the Internet chain, but also allows nodes on different blockchains to freely and dynamically join and exit the Internet chain network, so that the Internet chain architecture can be flexibly expanded.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to an interconnected chain architecture. Specifically, it may involve the data verification method of the parallel link entering the interconnection chain, the data sending and receiving method of the parallel link entering the interconnection chain, the interconnection chain, the parachain, the data verification node and the data sending and receiving node). Background technique [0002] Since the introduction of Bitcoin, blockchain technology has developed rapidly. At present, a variety of independent blockchains have emerged. The need to process data across different blockchains (referred to as cross-chain) has become an urgent requirement in today's blockchain applications. At present, the solutions for cross-chain data processing mainly include: solutions based on relay technology and solutions based on notary technology. After research, the applicant found that the exi...
