Description
Technical Field
The present invention relates to a method for trading cryptocurrency, and more particularly, to a system and method for trading cryptocurrency.
Technical Field
In recent years, bitcoins have received much attention along with other types of cryptocurrency that have been derived. While more and more people recognize and agree on the virtual money, the business scale of the cryptocurrency exchange is rapidly expanding. However, as a centralized mechanism, the digital currency exchange maintains confidence by credit, and stores a large amount of cryptocurrency, which is easy to be stolen and has serious consequences on the exchange fraud, a great risk is formed.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a cryptocurrency transaction system and a cryptocurrency transaction method, which are used for improving the security of cryptocurrency transaction and reducing the fraud risk of an exchange.
The invention can be used for designing an exchange system of the encryption currency and the legal currency, reduces the custody responsibility of a centralized exchange, and ensures that the exchange is safer and more credible.
A transaction system for encrypting currency comprises a data acquisition unit, a background management system, an encryption and decryption module, a user display end and a communication module. The data acquisition unit is connected with the background management system and is used for detecting whether related transactions occur on the P2P network; the communication module is connected with the background management system and is used for detecting the message sent by the user. The background management system receives the data collected by the data collector and then judges whether the transaction is normally carried out and controls the transaction flow; the user display end comprises a mobile phone, a tablet personal computer and a PC end, and a user searches for a transaction object through the user display end, determines transaction details and sends out transaction operation. The encryption and decryption module executes the generation of secret keys, the public key calculation, the address calculation operation and the encryption and decryption operation on the user display end and the background management system.
A method of using a cryptocurrency transaction system, comprising the steps of:
step 1, user joining and insurance fund acceptance.
And 2, the buyer and the seller negotiate to determine the transaction content by using the user display terminal.
And 3, randomly selecting the private key PA by the buyer through the encryption and decryption module and calculating the public key PA, and randomly selecting the private key PB by the seller through the encryption and decryption module and calculating the public key PB.
And 4, the two parties of the transaction report the transaction content to the background management system through the user display end, and the background management system receives the message through the communication module and locks the deposit of the two parties after confirming the consistency.
And 5, the buyer discloses PA, the seller discloses PB, the background system obtains PA and PB through the communication module, then calculates a new public key PA (+) PB through the encryption and decryption module, calculates a new address S, and simultaneously sends the obtained new public key PA (+) PB and the new address S to the buyer and the seller through the communication module.
And 6, the seller transfers the digital money to the new address S, and the background management system detects the transfer through a data receipt device. If the seller does not transfer correctly within one hour, step 11 is performed; if the transfer is correctly performed, step 7 is performed.
And 7, the background management system informs the buyer to pay the transaction price to the seller through the communication module. The seller confirms that the transaction price is obtained and then informs the background management system.
And 8, after confirming that the buyer pays the price, the background management system informs the seller of disclosing the private key pa and detects the private key pa by using the communication module. If the seller correctly discloses pa within an hour, step 10 is performed, if not, step 9 is performed.
And 9, the background management system returns the seller and the buyer guarantee fund as the indemnity fund to the buyer after one hour without finding that the seller correctly discloses pa through the communication module.
And step 10, the background management system releases the locking of the deposit between the buyer and the seller, the buyer uses pa to unlock the digital currency in the address S, and the transaction is completed.
And step 11, the background management system returns the seller and the buyer's guarantee fund to the buyer as the indemnity fund, and the transaction is finished.
Step 1 is realized as follows:
1-1, the user applies for joining, provides a bank account, conducts NYC verification, creates an account after the bank account passes the verification, and issues the use permission of the user display terminal.
1-2, the user pays the guarantee money of the user-defined amount.
The transaction content in step 2 comprises the digital currency amount of the transaction and the unit price.
The invention has the following beneficial effects:
the system of the invention reduces the risk of transaction. Transfer to an intermediate address is required for the seller, and the seller has less risk of completing the transfer but not paying the price. Since the purchaser will not get anything if he does not pay the consideration and will lose the margin. The transfer of the intermediate address is observable and verifiable to the purchaser, and there is no risk of the transfer of the intermediate account being maliciously transferred by a third party after the consideration is paid or the service is provided. The risk of the seller not presenting the private key is relatively small because if the seller does not present the private key, nothing is available. And the seller is returned a margin from the back office management system by presenting the private key to the buyer so that the buyer can complete the transfer.
For the background management system, only the deposit is required to be kept, and the digital currency is not required to be kept like the existing exchange. The benefit of fraud is reduced, and the capital flow is regulated by banking, so the cost of illegal actions is high.
