the first computing module is configured to sign the first transaction data to obtain second transaction data, and includes: invoking the first transaction data, the first transaction data comprising an initiator signature; the first transaction data is sent to a first encryption card, the first transaction data is used for triggering the first encryption card to check the validity of a signature of an initiator in the first transaction data, and the first encryption card is an encryption card corresponding to the transaction initiating node; receiving a first check value sent by the first encryption card, and if the first check value is a first state value, signing the first transaction data to obtain second transaction data, wherein the first check value comprises the first state value, the first state value indicates that a signature of an initiator in the first transaction data is a valid signature, and the second transaction data is the first transaction data with a signature of a transaction initiating node;
if the first check value is the first state value, signing the first transaction data to obtain second transaction data, and further including: checking a transaction type corresponding to the first transaction data, and confirming at least one first voting node according to the transaction type;
the second calculation module is used for sending the second transaction data to at least one first voting node and receiving the first voting data sent by each first voting node, wherein the first voting node is a node which needs to vote on the second transaction data in a blockchain network;
the third calculation module is used for packaging the plurality of first voting data in the second transaction data to obtain third transaction data, and sending the third transaction data to a master node, wherein the third transaction data is used for triggering the master node to send the third transaction data to each node in a blockchain network;
the fourth calculation module is used for acquiring the third transaction data sent by the master node and sending the third transaction data to a first encryption card, wherein the first encryption card is an encryption card corresponding to the transaction initiating node and is used for checking signature validity of the third transaction data;
and the fifth calculation module is used for receiving the detection instruction sent by the first encryption card and processing the third transaction data according to the detection instruction.
4. A blockchain transaction device based on an encryption card, comprising:
a memory for storing a computer program;
a processor for implementing the steps of the encryption card-based blockchain transaction method of any of claims 1 to 2 when executing the computer program.
