In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Fig. 1 is a schematic flow chart of a payment method based on a blockchain system according to an embodiment of the present invention, as shown in fig. 1, the payment method based on the blockchain system includes the following steps:
and S101, when a payment request sent by a first user terminal is acquired, controlling the transfer pool to start.
That is, when the blockchain system acquires a payment request sent by the first user end, the relay pool is controlled to start so as to process the payment request.
As an example, the transit pool is set as a trusted transaction address that is system-hardened, and a corresponding public key and private key are configured for the transit pool.
And S102, the first user end sends a first transaction request to the transfer pool, encrypts the first transaction request by adopting a first encryption mode, sends transaction address information of the second user end to the transfer pool, and encrypts the transaction address information of the second user end by adopting a second encryption mode, wherein the first transaction request comprises the transaction address information of the first user end, the transaction address information of the transfer pool and transaction amount information.
That is, after the transit pool is started, the first user sends a first transaction request to the transit pool, wherein the first transaction request comprises transaction address information of the first user, transaction address information of the transit pool and transaction amount information; the first user terminal encrypts the first transaction request in a first encryption mode; meanwhile, the first user end also sends the transaction address information of the second user end to the transfer pool, and encrypts the transaction address information of the user end by adopting a second encryption mode.
The first user end refers to an initiator of the transaction request, and the second user end refers to a receiver of the transaction request.
As an example, the encrypting the first transaction request by using the first encryption manner specifically includes: the first user terminal encrypts the first transaction request by using a first user terminal private key.
As an example, the encrypting the transaction address information of the second user end by using the second encryption manner specifically includes: and the first user terminal encrypts the transaction address information of the second user terminal by adopting the transit pool public key.
It should be noted that the public key and the private key are a key pair obtained through an algorithm, the public key is a public part of the key pair, and the private key is a non-public part. The key pair derived by such an 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 corresponding key must be used to decrypt the piece of data; for example, data encrypted using a public key must be decrypted using the corresponding private key; alternatively, data encrypted using a private key must be decrypted using the corresponding public key, otherwise decryption will not succeed.
S103, the transfer pool decrypts and verifies the first transaction request, judges that the first user side meets transaction conditions and obtains transaction amount after the first transaction request passes the verification, and decrypts the encrypted transaction address information of the second user side to obtain the transaction address of the second user side.
That is to say, after receiving the first transaction request, the transit pool decrypts the first transaction request, verifies whether the first user side meets the transaction condition according to the transaction address information of the first user side in the first transaction request, obtains the transaction amount after verifying that the first user side meets the transaction condition, and simultaneously decrypts the encrypted transaction address information of the second user side to obtain the transaction address of the second user side.
As an example, the decrypting and verifying the first transaction request specifically means that the transfer pool decrypts the first transaction request by using a first user public key to obtain transaction address information of the first user, transaction address information of the transfer pool, and transaction amount information in the first transaction request; and verifying whether the corresponding first user side meets the condition for conducting transaction according to the transaction amount information according to the transaction address information of the first user side (for example, when the transaction amount information is 50 bitcoins, judging whether the first user side is an owner of the 50 bitcoins according to the transaction address information of the first user side, and if so, determining that the first user side meets the condition for conducting transaction according to the transaction amount information).
As an example, decrypting the encrypted transaction address information of the second user end to obtain the transaction address of the second user end specifically means that the transfer pool decrypts the encrypted transaction address information of the second user end by using a transfer pool private key to obtain the transaction address information of the second user end.
And S104, the transfer pool sends a second transaction request to the second user end according to the transaction address of the second user end, encrypts the second transaction request by adopting a third encryption mode, simultaneously sends the transaction address information of the first user end to the second user end, and encrypts the transaction address information of the first user end by adopting a fourth encryption mode, wherein the second transaction request comprises the transaction address information of the second user end, the transaction address information of the transfer pool and the transaction amount information.
That is to say, after decrypting the encrypted first transaction request and the transaction address information of the second user, the transit pool acquires the transaction address information of the first user, the transaction address information of the transit pool, the transaction amount information and the transaction address information of the second user in the first transaction request; sending a second transaction request to the second user end according to the transaction address of the second user end, and encrypting the second transaction request by adopting a third encryption mode; meanwhile, the transaction address information of the first user end is sent to the second user end, and the transaction address information of the first user end is encrypted by adopting a fourth encryption mode; the second transaction request comprises transaction address information of the second user end, transaction address information of the transfer pool and transaction amount information.
As an example, the encrypting the second transaction request by using the third encryption manner specifically means that the transit pool encrypts the second transaction request by using a transit pool private key.
As an example, encrypting the transaction address information of the first user by using the fourth encryption manner specifically means that the transit pool encrypts the transaction address information of the first user by using the public key of the second user.
And S105, the second user terminal decrypts and verifies the second transaction request, judges that the transit pool meets the transaction condition and obtains the transaction amount after the second transaction request passes the verification, and decrypts the encrypted transaction address information of the first user terminal to obtain the transaction address of the first user terminal so as to complete the payment process from the first user terminal to the second user terminal.
That is to say, after receiving the second transaction request sent by the transit pool, the second user end decrypts the second transaction request, verifies whether the transit pool meets the condition of performing transaction according to the transaction amount information according to the transaction address information of the transit pool in the second transaction request, and obtains the transaction amount after the verification is passed; meanwhile, after receiving the encrypted transaction address information of the first user end sent by the relay pool, the second user end decrypts the transaction address information of the first user end to obtain the transaction address of the first user end, so that the payment process from the first user end to the second user end is completed.
As an example, after receiving a second transaction request sent by a transit pool, a second user terminal decrypts the second transaction request by using a transit pool public key to obtain transaction address information of the second user terminal, transaction address information of the transit pool and transaction amount information in the second transaction request, verifies whether the transit pool meets a condition for performing a transaction according to the transaction amount information according to the transaction address information of the transit pool in the second transaction request, and obtains a transaction amount after the verification is passed; meanwhile, the second user end also adopts a second user end private key to decrypt the encrypted transaction address information of the first user end so as to obtain the transaction address information of the first user end, and therefore the payment initiator corresponding to the transaction amount is obtained.
In summary, according to the payment method based on the blockchain system in the embodiment of the present invention, first, when a payment request sent by a first user is obtained, a relay pool is controlled to start; then, the first user end sends a first transaction request to the transfer pool, encrypts the first transaction request by adopting a first encryption mode, sends transaction address information of a second user end to the transfer pool, and encrypts the transaction address information of the second user end by adopting a second encryption mode, wherein the first transaction request comprises the transaction address information of the first user end, the transaction address information of the transfer pool and transaction amount information; then, the transfer pool decrypts and verifies the first transaction request, judges that the first user end meets transaction conditions and obtains transaction amount after the first transaction request passes the verification, and decrypts the encrypted transaction address information of the second user end to obtain the transaction address of the second user end; then, the transfer pool sends a second transaction request to the second user end according to the transaction address of the second user end, encrypts the second transaction request by adopting a third encryption mode, simultaneously sends the transaction address information of the first user end to the second user end, and encrypts the transaction address information of the first user end by adopting a fourth encryption mode, wherein the second transaction request comprises the transaction address information of the second user end, the transaction address information of the transfer pool and the transaction amount information; then, the second user terminal decrypts and verifies the second transaction request, judges that the transit pool meets the transaction condition and obtains the transaction amount after the second transaction request passes the verification, and decrypts the encrypted transaction address information of the first user terminal to obtain the transaction address of the first user terminal so as to complete the payment process from the first user terminal to the second user terminal; therefore, the user can pay in the blockchain system in an anonymous mode, the privacy of the user is guaranteed, and meanwhile the safety of the blockchain system is improved.
