Fig. 1 is a schematic flow chart of a packet processing method based on a block chain according to an embodiment of the present invention. In the embodiment of the present invention, the SWIFT (Society for world wide Interbank Financial telecommunications Society of the same industry as banking, international banking and telecommunications) is one of the most important international Financial communication network systems, the format of the SWIFT has standardization, and the format of the current transmission message mainly uses the format of the SWIFT message.
In this embodiment, the method for processing a packet based on a block chain includes:
s1, acquiring transaction data of the cross-border transaction request from the pre-constructed blockchain network, and calculating a transaction hash value of the transaction data;
in the embodiment of the invention, the block chain network is constructed by a primary network and a secondary network. Specifically, the blockchain network is jointly established by a financial institution, a local bank and an agency with independent SWIFT system authority. The financial institution with the independent SWIFT system authority is established as a primary network of the preset block chain network, and the local bank and the agency are established as a secondary network of the preset block chain network. The primary network adopts a P2P mode to construct a alliance chain, and the secondary network adopts a star topology structure to construct a private chain.
The nodes in the primary network are divided into an accounting node set, a verification node set and a contract node set, wherein the accounting node set is mainly used as an accounting book record; the verification node set is used for verifying the authenticity of the transaction data; the contract node set is an agency of a committee which is formed by the financial institutions with independent SWIFT system authority, does not participate in verification, and is responsible for maintaining the order of the system.
In the embodiment of the invention, the primary network in the block chain network can ensure information safety and can avoid the intervention of a certain country; the secondary network is beneficial to the state to supervise the transaction data and lock illegal transactions in China.
The verification node set is K × N nodes randomly selected from the primary network nodes by the contract node, wherein K is a parameter for balancing verification efficiency and credibility, and when the number of nodes in the alliance is large, K can set a small parameter to improve verification efficiency.
The secondary network is used for sending SWIFT access authority, transaction requests, receiving cross-border message information and the like. In an embodiment of the present invention, the transaction data may be transaction data of one or more transactions.
In detail, referring to fig. 2, the calculating a transaction hash value of the transaction data in S1 includes:

s13, dividing the transaction data in the binary coding format with the preset length into transaction data blocks;
and S14, performing circular summary calculation on the transaction data block to obtain a transaction hash value of the transaction data.
Specifically, the embodiment of the present invention complements the transaction data in the binary code format to obtain the transaction data in the binary code format with the preset length. The preset length may be a multiple of 512 bits, and the transaction data block may be a block of transaction data in 512 bits.
The hash function in the embodiment of the invention can convert an input with any length into an output with a fixed length, wherein the output is a hash value, and the hash value can be a digital fingerprint and is a method for creating a small digital fingerprint from any kind of data. The hash function compresses the transaction data into digests, reducing the amount of data, fixing the format of the data, and scrambling and mixing the digests to recreate a fingerprint called a hash value. The hash value is typically represented by a short string of random letters and numbers. The hash value of the transaction data is unchanged for the preset hash function, but the hash value can be changed greatly only by modifying one bit of the transaction data, so that the SWIFT message can be ensured not to be tampered in the processing process by judging the hash value, and the safety of SWIFT message processing is ensured.

In the embodiment of the invention, the encryption key and the decryption private key are key pairs obtained through an algorithm, the encryption key is a part which is open to the outside, the decryption private key is a non-public part, and the key pairs obtained through the algorithm can be guaranteed to be unique worldwide. When using this key pair, if one of the keys is used to encrypt a piece of data, the other key must be used to decrypt the piece of data.

For example: and the verification node directly determines whether the transaction amount exceeds the balance according to the account balance of the transaction initiator on the account book of the verification node, if so, the compliance examination is not passed, and if not, the compliance examination is passed.
For example, the compliance verification of the geographic location refers to that a verification node queries whether effective addresses of the transaction initiator and the transaction receiver are correct, if the effective addresses are wrong, the compliance verification of the geographic location does not pass, and if the effective addresses are correct, the compliance verification of the geographic location passes.

traversing each verification node in the verification node set to obtain the consistency verification passing condition of each verification node;
and summarizing the consistency verification passing condition of each verification node to obtain the consistency verification passing rate of the transaction data.
In the embodiment of the present invention, since the transaction hash values are obviously different even when there is a slight change in the transaction data, the verification hash value of the transaction data obtained from the encrypted data is calculated by using the hash function preset in S1, and when the transaction hash value is the same as the verification hash value, it indicates that the transaction data obtained from the encrypted data has not been tampered.
According to the embodiment of the invention, if consistency verification is carried out only by one verification node, the possibility of verification error or false exists, so that each verification node in the verification node set is traversed to obtain the consistency verification passing condition of each verification node, and the consistency verification passing rate of the transaction data is obtained by summarizing the consistency verification passing condition of each verification node.

The preset threshold is 50%, and when the consistency verification passing rate received by the contract node is 60%, the sizes of 50% and 60% are compared.
When the consistency verification passing rate is smaller than a preset threshold value, S5, judging that the cross-border transaction request is not verified;
in the embodiment of the invention, when the consistency verification passing rate x is less than or equal to the preset threshold tau, the transaction information is not credible, and the cross-border transaction cannot be executed by sending the message that the cross-border transaction is not verified.
When the consistency verification passing rate is greater than or equal to the preset threshold value, S6, determining that the cross-border transaction request passes verification, executing the cross-border transaction request, and packaging the transaction data into a message data block;
in the embodiment of the present invention, when the consistency verification passing rate x is greater than the preset threshold τ, it indicates that the transaction information is trusted, the cross-border transaction passes verification, the cross-border transaction request is executed, the contract node establishes a message data block, and encapsulates the transaction data and the transaction hash value into the message data block.
S7, broadcasting the message data block to the block chain network, and recording the message data block.
