Problems solved by technology
When there is a business that requires transaction summarization, the business request requires an external node other than the public chain node to vote in favor; and the response of the external node may slow down and the internal nodes of the public chain will be suspended
In addition, in some cases, when there is indeed an error in the block data in a certain block on the public chain, if the data is forcibly modified, it will inevitably lead to the failure of the synchronization verification of the public chain, resulting in the modification of the block data and the public Contradictions between chain synchronization verification

The present invention provides an encrypted backup method for public chain data. The method comprises: constructing a new block by using new transaction data, wherein the new block includes transaction data packet and block metadata information, the block metadata information includes a block metadata information digest value of a preamble block in a public chain of the node; determining a consensus block satisfying the consensus rules from a new block generated from all nodes of the public chain by a consensus algorithm and adding the consensus block into the public chain. The encrypted backup method for public chain data provides an encrypted backup method for public chain data, which realizes data synchronization verification between blocks by using the public chain own system, and quickly corrects errors existing in block data.
Description
technical field [0001] The invention relates to block chains, in particular to a public chain data encryption backup method. Background technique [0002] The public chain technology replaces the current Internet's dependence on the central server with data blocks, so that all data changes or transaction items are recorded on multiple ledger nodes at the same time. The existing public chain generates new blocks sequentially along the extension direction of the public chain, and the blocks satisfy synchronous verification to prevent the data in the blocks from being maliciously tampered with. When there is a business that requires transaction summarization, the business request needs to be voted by external nodes other than the public chain nodes; and the response of external nodes may slow down and the internal nodes of the public chain will be suspended. In addition, in some cases, when there is indeed an error in the block data in a certain block on the public chain, if t...
