The present invention relates to a transaction information processing apparatus. More specifically, the present invention relates to a transaction information processing apparatus for a use-specific cryptocurrency.

Recently, interest in bitcoin, a kind of digital cryptocurrency that can pay in kind, has been highlighted.

Bitcoin is a digital currency created by Satoshi Nakamoto in 2009. It has a structure without a central device for issuing and managing the currency. Instead, Bitcoin's transactions are made through a peer-to-peer network-based distributed database, which typically performs transactions using public key encryption algorithms.

Such digital cryptocurrency that can be paid for in kind, in addition to Bitcoin, Litecoin, Darkcoin, Namecoin, Dogicoin, Ripple, etc., the common feature is that traders use digital cryptocurrency including Bitcoin The book of the transaction transaction is stored in the electronic wallet, the books are sequentially connected according to the block and hash conversion in a certain unit, can be shared on the blockchain network in a form that can be verified by the hash comparison. Such cryptocurrency can be exemplified by Bitcoin, Litecoin, Darkcoin, Namecoin, Dogecoin, Ripple and the like.

Individual blocks connected to the blockchain may be sequentially connected according to a hash transformation, and may be configured in the form of a data packet including a plurality of information. For example, the information contained within the block may be the transaction history of the participants trading the currency, and the hash value, difficulty, nonnce, etc. of the previous block. Each block contains the hash value of the previous block, and these blocks can form a blockchain that contains the transfer history in chronological order.

Once such a blockchain network is formed, one transaction ledger can be shared through the nodes connected to that network, and the transaction ledger can be preserved by a blockchain that is verified and formed by an unspecified number of nodes. Such a transaction book is continuously shared and verified and preserved by all of the node terminals connected to the network, so that forgery of the transaction book is prevented by the majority of nodes that wish to maintain the transaction system.

In addition, the target of the attack such as hacking on the blockchain network should be the transaction system itself consisting of an unspecified number of nodes instead of a specific terminal, and since the action itself destroys the transaction system itself, The low gain value prevents the establishment of hacking in advance, thus enabling the establishment of reliable distributed transactions of cryptocurrencies without separate central control.

However, such blockchain-based trading technology is based on the anonymity that anyone can join and participate in, and limiting it can undermine system stability, which leads to various social problems, For example, bribery, illegal money laundering, embezzlement of money, embezzlement of money, and the creation of slush funds can occur.

The process for verification processing may be pre-registered in the form of a code such as SMART CONTRACT in the transaction book data shared on the blockchain network, and thus forgery may be prevented.

Accordingly, according to the verification of the cryptocurrency transaction information including the use restriction code, the trader terminal 100 processes the verifier to verify during the third party transaction of the money collector who collects the cryptocurrency, thereby making it available only to the designated place of use when remitting. It is possible to provide a transaction information processing method and apparatus for cryptocurrency that can be distributed and verified by nodes connected on a blockchain network such that it cannot be traded or used for limited purposes.

3 to 5 are flowcharts illustrating in more detail a method of processing transaction information of a cryptocurrency according to an embodiment of the present invention.

First, FIG. 3 illustrates an operation of the first trader terminal 100 as a remitter. First, the trader terminal 100 accesses a blockchain network and registers node information (S1001).

The node information may include, for example, account information of the remitter connected through the first trader terminal 100. The account information may be an encryption key previously issued for the account registration of the remitter and the public key information of the remitter. It may include.

In addition, the first trader terminal 100 receives the collector node information and the transaction amount information through the user input unit 140 (S1003).

Here, the collector node information may be a pre-issued encryption key for registering a remitter's account, and may include the collector's public key information.

Subsequently, when the input of the usage information corresponding to the transaction amount information is confirmed (S1005), the first trader terminal 100 generates a usage restriction code corresponding to the usage information through the usage restriction code generation unit 110. (S1007).

When the usage restriction code is generated and a password corresponding to the transaction information is input, the first trader terminal 100 generates cryptocurrency transaction information including the usage restriction code through the control unit 130 (S1009). .

On the other hand, when the usage information is not input, the first trader terminal 100 receives the password for the normal transaction amount and generates general cryptocurrency transaction information (S1013).

Thereafter, the first trader terminal 100 shares the generated cryptocurrency transaction information on the blockchain network through the communication unit 120 (S1011), and the shared transaction information is verified and approved from other nodes, The transaction approval may be processed by updating the blockchain generated according to the approval of the node equal to or higher than the ratio and transaction book data corresponding thereto (S1015).

On the other hand, Figure 4 is for explaining the transaction information processing operation of the second trader terminal 200, the collector, the second trader terminal 200 and the third node information corresponding to the third node to trade cryptocurrency and The transaction amount information is input (S2001).

Here, the second trader terminal 200 determines whether the cryptocurrency corresponding to the transaction value information is a limited use cryptocurrency (S2003).

Here, in the case of the usage-limited cryptocurrency, it may be recorded separately from the general cryptocurrency, and a usage restriction code corresponding to a certain unit may be set. The usage restriction code may include, for example, usage restriction information or usage specification information corresponding to a certain unit of cryptocurrency, and may include counter information that can be subtracted according to the number of transactions. This will be described later in more detail.

In the case of a transaction for the restricted cryptocurrency, the second trader terminal 200 shares the verification processing request based on the usage restriction code and the third party node information on the blockchain network (S2005), and Obtain the verification result information (S2007).

For example, the verification result information may indicate whether operator information corresponding to the node information of the third party exists in a block shared in advance through the blockchain network, and whether the operator information is associated with the usage restriction code. Can be.

In order to process the verification result, the second trader terminal 200 may request distributed verification processing to one or more node terminals connected to the blockchain network, whereby verification processing of a predetermined ratio or more of the blockchain network is confirmed. In this case, it can be obtained as verification result information and recorded in the transaction book data. Here, the verification result information may include flag information (true or false) indicating whether to verify.

If the verification result is found to be true, that is, for example, the operator information in the third party node information is identified as a carrier designated by the restriction code, or identified as a carrier not restricted by the restriction code, the second trader terminal. 200 may share the cryptocurrency transaction information including the verification result information and the usage restriction code on the blockchain network (S2009). However, if the verification result is false, the second trader terminal 200 may output a message indicating the failure of the transaction request itself.

Here, the usage restriction code may be included only when there is more than one remaining counter information of the usage restriction code. When the counter information of the usage restriction code is 0, the usage restriction code is released. May be treated as a regular transaction. Therefore, the application-specific cryptocurrency according to an embodiment of the present invention can be converted into a general cryptocurrency according to a predetermined condition such as counter exhaustion.

On the other hand, when the usage is not limited cryptocurrency, the second trader terminal 200 generates transaction information to the third party node corresponding to the general cryptocurrency (S2013), and shares the generated general transaction information (S2015). .

Thereafter, when the shared cryptocurrency transaction information is approved, the second trader terminal 200 may check the transaction approval result corresponding to the blockchain generation of the transaction information according to the update of the transaction book data (S2011).

Meanwhile, FIG. 5 illustrates an operation of the third trader terminal 300 to provide distributed verification processing. First, the third trader terminal 300 is used from a verification process request shared from the second trader terminal 200. The restriction code is identified (S3001).

In addition, the third trader terminal 300 obtains operator information of the third party node corresponding to the usage restriction code from the blockchain transaction book data (S3003).
