A block chain-based transaction method, the improvement of which is that the method includes: a server receives a transaction sent by a user terminal, wherein the transaction includes a transaction category, an associated account number, and a transaction status; the server receives the transaction from the transaction Extract the transaction type, associated account number, and transaction status from it, and judge whether the transaction type is a financial transfer; when the transaction type is a financial transfer, the server accesses the transaction pool and/or the block chain through the node and judge whether the target transaction related to the associated account is screened out from the transaction pool and/or block chain; when the target transaction related to the associated account is screened out, the server calculates the According to the result of the target transaction and judging whether the transaction is correct or not, mark the transaction status of the correct transaction as pending on-chain, and send the marked transaction to the user terminal for For the user terminal to confirm, wherein the server sequentially calculates the result of the target transaction according to the time sequence and judges whether the transaction is correct according to the result of the target transaction includes: sequentially calculating the target transaction according to the time sequence Whether the content of the target transaction is consistent; when the content of the target transaction is consistent, determine that the transaction is correct; and when the content of the transaction is inconsistent, determine that the transaction is incorrect; and the server receives the transaction sent by the user terminal successfully Or the confirmation information of the transaction failure, and when receiving the confirmation information of the transaction success, mark the transaction status of the transaction as confirmed and package the transaction into a block and chain it to the block chain by the node , including: the server transmits the transaction whose transaction status is to be linked to the transaction pool through the node, and when receiving the confirmation information of the successful transaction sent by the user terminal, through the The node extracts the transaction from the transaction pool, and packages the transaction into a block and links it to the block chain through the node. The transaction method based on block chain as described in claim 1, wherein, the method also includes: When the transaction type is reserved for transaction records, the server accesses the transaction pool and/or block chain through the node, and screens the transaction pool and/or block chain from the transaction pool and/or block chain All target transactions associated with the above transactions, calculate the results of the target transactions in sequence according to the time sequence, and package the transactions corresponding to the target transactions with correct calculation results into blocks and chain them to the blockchain by nodes . The transaction method based on block chain as described in claim 1, wherein the method further includes: when no target transaction related to the associated account is screened out, the server uses the node from the Read the balance of the associated account of the transaction in the block chain and judge whether the transaction is correct according to the balance of the associated account, mark the transaction status of the correct transaction as waiting to be uploaded, and mark the marked transaction sent to the user terminal for confirmation by the user terminal. The transaction method based on block chain as described in Claim 1, wherein the method further includes: when the server receives the information of transaction failure, it marks the transaction status of the transaction as failed, and through the The node sends the marked transaction to the user terminal. The blockchain-based transaction method as described in claim 1, wherein the method further includes: the server marks the transaction status of the incorrect transaction as failure, and sends the marked transaction to the user user terminal, and notify the user terminal to delete the transaction. The transaction method based on block chain as described in claim 3, wherein, the server uses the node to read the balance of the associated account of the transaction from the block chain and according to the balance of the associated account The balance judging whether the transaction is correct includes: determining that the transaction is correct when the balance of the transfer account in the account associated with the transaction is not less than the transfer amount, otherwise determining that the transaction is incorrect. A block chain-based transaction device, the improvement of which is that the device includes: a receiving module for receiving a transaction sent by a user terminal, wherein the transaction includes a transaction category, an associated account number, and a transaction status; The transaction category judging module is used to extract the transaction category, associated account number and transaction status from the transaction, and judges whether the transaction category is a financial transfer; the screening module is used when the transaction category is a financial transfer When the node accesses the transaction pool and/or block chain and judges whether the target transaction related to the associated account is screened out from the transaction pool and/or block chain; the transaction result judgment module is used for when When screening out the target transactions related to the associated account, calculate the results of the target transactions in sequence according to the time sequence and judge whether the transactions are correct according to the results of the target transactions, and mark the transaction status of the correct transaction as pending chain, and send the marked transaction to the user terminal for confirmation by the user terminal, wherein the result of the target transaction is calculated sequentially according to the time sequence and the target transaction is judged according to the result of the target transaction Whether the transaction is correct includes: sequentially calculating whether the content of the target transaction is consistent according to the time sequence; determining that the transaction is correct when the content of the target transaction is consistent; and determining that the transaction is incorrect when the content of the transaction is inconsistent ; and an on-chain module, which is used to receive the confirmation information of successful transaction or transaction failure sent by the user terminal, and when receiving the confirmation information of successful transaction, mark the transaction status of the transaction as confirmed and pass the The node packs the transaction into a block and uploads it to the blockchain, including: the server sends the transaction whose transaction status is to be linked to the transaction pool through the node, when When the transaction success confirmation information sent by the user terminal is received, the node extracts the transaction from the transaction pool, and the node packages the transaction into a block and chains it to the block in the block chain. An electronic device, the improvement of which is that the electronic device includes a processor and a memory, and the processor is used to execute the computer program stored in the memory to implement the region-based Blockchain transaction method.
