Embodiment Construction
[0073] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0074] figure 1 It is an overall flow chart of the block chain offline transaction method based on identification authentication from on-chain to off-chain in an embodiment, as shown in figure 1 As shown, the above methods include:
[0075] Step 110, assets are transferred from the on-chain payer's account to the off-chain payer's virtual card.
[0076] When the payer's account needs to pay to the payee's account, and it needs to be realized through offline transactions, the assets can be transferred from the payer's account to the off-chain payer's virtual card first.
[0077] Step 120, assets ...

The present invention relates to a block chain offline transaction method and system based on identification authentication. The method includes: the virtual card of the payee generates first initial information, and sends the first initial information to the virtual card of the payer; The first initial information includes at least the payee identification and the first transaction amount; the payer virtual card generates first transaction information based on the verified first initial information, and the first transaction information includes at least the The payer's virtual card deducts the transaction information of the same asset as the first transaction amount in the first initial information; the payer's virtual card generates first transaction verification information based on the first transaction information; the payee's virtual card The card adds the same asset as the first transaction amount based on the verified first transaction verification information. The invention can realize safe and convenient offline transaction under the chain.
Description
technical field [0001] The present invention relates to the field of computers, in particular to a block chain offline transaction method and system based on identification authentication. Background technique [0002] Blockchain is a combination of Internet protocols and technologies about trust. The purpose is to build a distributed deployment and real-time synchronization system. The data in it can only be added but not tampered with. At the same time, it allows multiple parties to participate in the establishment of data according to the consensus mechanism. And maintenance, to ensure that each valid node on the chain has completely consistent data. [0003] In blockchain technology, in order to ensure the security of each transaction, even a small transaction requires a consensus on the entire network, which not only brings inconvenience to both parties of the transaction, but also consumes a lot of computing resources. Therefore, in some blockchains, in order to solve...
