1 is a networked device based on block 900 chain. Although only five devices are illustrated in FIG. 1, the number of block-based devices in the block 900 is not limited to five, but may be less or more.

The block producer node 100 generates and transmits a block 900 including event announcement information to the applicant terminal device 1100. The block producer node (BP) 100 is a blockchain provider server device. Although the server device of the event organizer is not shown, it is not connected to the blockchain network and can perform simple wireless communication with the block producer node (BP) 100. In FIG. 1, the block producer node (BP) 100 is connected to the applicant terminal device 1100 in a block chain network, but is not limited thereto. Only the applicant terminal devices 1100 may be connected in a block chain network. have.

In addition, the block producer node (BP) 100 may be connected to the blockchain network only until the disclosure of the intelligent contract and the deposit of the margin to the event host server. After the publication of the intelligent contract, the smart contract automatically and immediately implements the contractual terms on the basis of the specific mechanism. The intelligent contract and margin deposit information is provided by the server apparatus of the event organizer to the block producer node 100.

The event announcement information includes at least one of tax information, winning reward information, and an event schedule. The event announcement information is information that can be recognized by the applicants to the event. The tax information is information about the tax corresponding to the winning prize when the winning prize is handed to the applicant. As shown in FIG. 3, the block producer node (BP) 100 may be network-connected with the IRS server device 3100 to receive tax information according to the winnings from the IRS server device 3100. In addition, when the winnings are actually paid to the winners, the information required for the tax return can be immediately transmitted to the IRS server device 3100 to unify the tax processing.

Winning reward information includes information such as winning amount and deposit information. Conventionally, the winning amount according to the event winning was confirmed, but the information on the depository bank, etc. included in the deposit information could not be confirmed. The deposit information includes information such as deposit amount, deposit time, deposit bank, and the like. The depositary object is not limited to money, but may be a garden. If the depositary object is a garden, the deposit information may include market price information of the garden. The event schedule includes information such as an entry start date and a winning date.

The block producer node (BP) 100 generates event announcement information, and converts the event announcement information into blocks 900 to transmit them to all distributed devices. Referring to FIG. 1, all of the distributed devices are the applicant terminal devices 1100.

In the present invention, the step of generating and transmitting the block 900 may be followed by determining the validity included in the block 900 and acknowledging the validity.

One applicant terminal device 1100 generates and transmits a block 900 including event entry information to another applicant terminal device 1100 and a block producer node 100 (BP). The event entry information includes at least one of a bank name, a bank account number, a phone number, a date of birth, an entry time, a place, and a random number. The name of the bank is the bank where the applicant will receive the winnings, and the account number is the account number or blockchain account address of the bank that will receive the winnings. The telephone number is the applicant's telephone number, and the date of birth is the applicant's date of birth. The entry time is the time when the applicant entered through the applicant terminal device 1100, and the position of the applicant at the time when the applicant entered the application is a place. The applicant terminal device 1100 may be equipped with a GPS module to estimate a position at the time of entry. The random number is any number, and at the time of entry, the random number generator generates a random number. The random number generator may be software included in the applicant terminal device 1100, or may be a random number generator provided by a block producer (BP) 100.

When the block producer node 100 receives the block 900 including the event entry information, the block producer node 100 generates the chain of the block 900 by approving the event entry information. The block producer 100 may provide a lottery result verification interface to the entrant terminal device 1100 that has transmitted the block 900 including the event entry information. The entrant terminal device 1100 may verify the winner by executing the lottery result verification interface to determine whether the selected winner is authentic.

In addition, when the block producer node (BP) 100 having received the block 900 including the event entry information generates the chain of the block 900 by approving the event entry information, the block generation node ( The block producer (BP) 100 may transmit an entry receipt to the entrant terminal device 1100 that has transmitted the block 900 including the event entry information.

One applicant terminal device 1100 generates event entry information corresponding to an event entry from a user, and the other applicant terminal device 1100 and the block generation node BP connected to the block-based network. producer) (100).

In the transmitting of the event entry information, the entry information generated by one of the applicant terminal devices 1100 may include entry information for a plurality of users. That is, for example, when a lottery club consisting of 10 people participates in an event jointly, one applicant terminal device sends the event entry information for 10 people to another applicant terminal device and a block producer node (BP). Can transmit As the number of event entries increases according to the number of people, the probability of winning the prize can be increased accordingly. At this time, the distribution of the winnings is made in proportion to the individual application amount.

The validity of the information included in the block 900 received by the applicant terminal device 1100 and the block producer node 100 is determined.

In the block-based event winning processing method, each applicant terminal generates a public key and a private key and delivers the public key to another applicant terminal and a block producer node (BP) 100. And, the private key further comprises the step of storing in the applicant terminal. The applicant terminal device 1100 may determine validity by checking information included in each block 900 using a public key encryption algorithm.

Finally, the manager server may transmit the winnings, which use the public key of the winner terminal device 1100 as the recipient, to all applicant terminal devices 1100 on the P2P network. Here, all the applicant terminal devices 1100 are all the applicant terminal devices 1100 that perform P2P communication based on the block 900 chain. Although the applicant terminal device 1100 connected to the block 900 chain receives the prize money, the only person who can actually use the prize money is a device having the private key of the applicant terminal device 1100 which is the winner.

Anyone can verify that the winner terminal device 1100, who is the winner, is the person who will receive the winning money using a public key encryption algorithm.

A majority or more devices confirm the validity of the event entry information, and the block producer node (BP) 100 approves the event entry information. When the validity of the event entry information is confirmed and approved by the block producer node (BP) 100, the applicant terminal device 1100 and the block producer node (BP) 100 receive the approved event entry information. A block 900 including the block 900 is connected to the previous block 900 to generate a block 900 chain.

Previous block 900 refers to block 900 that includes information that has previously been validated or has been validated and verified. The generated block 900 chain may be registered in each of the devices shown in FIG.

The information included in the block 900 is the hash value, difficulty, nonce, etc. of the previous block 900, in addition to the event entry information or event announcement information described above. Each block 900 contains the hash value of the previous block 900, and the subsequent blocks 900 form a block 900 chain containing the details generated in chronological order. Each block 900 may be extended to a size of up to several kilobytes to several thousand megabytes (MB), and may be used for storing transfer details except for a few bytes or more of headers and other bytes or more.

And generating and transmitting a block 900 including the winning information to the applicant terminal device 1100 by the block producer node 100, wherein the winning information is one of the winnings and the winners. The block producer node 100 may include at least one, and seed the data contained in at least one of a plurality of fields included in all blocks accumulated in the winner's announcement day or the last generated block. Set to. The seed is hashed to calculate a hash value, and a winner corresponding to the applicant number corresponding to the remainder obtained by dividing the hash value by the number of applicants is selected as a winner. That is, the block producer node 100 performs a modulo P operation on the hash value to determine the winner.

The block producer node (BP) 100 generates and transmits a block 900 including the winning information to the applicant terminal device 1100 on the winning date. At this time, the block producer node (BP) 100 generates and transmits a block 900 including the winning information to all the applicant terminal devices 1100. At this time, the winning information includes at least one of the winnings and the winners.

In addition, the block producer node (BP) 100 according to the present invention selects a winner by a method distinguished from the prior art.

The block producer node (BP) 100 calculates a hash value by hashing data included in at least one of a plurality of fields included in all blocks accumulated or the last generated block until the winner's announcement date, and The winner corresponding to the applicant number corresponding to the remainder obtained by dividing the hash value by the number of applicants is selected as a winner. As shown in FIG. 4, the block producer node (BP) 100 hashes data included in at least one of a plurality of fields included in all of the accumulated blocks or the last generated block, and generates a hash value. Calculate. The key shown in FIG. 4 is data included in at least one of a plurality of fields included in all the cumulatively generated blocks or the last generated block.

The block producer node 100 may calculate a hash value through SHA256, MD5, or other hash function. The block producer (BP) 100 divides the calculated hash value by the number of applicants and calculates the remainder. The number of applicants is the number of terminal devices actually applied among applicant terminal devices 1100. If the hash value is 10 and the number of applicants is 4, the rest is 2.

The applicant number is a number previously set by the block producer (BP) 100 and assigned to each applicant terminal device 1100. There is no limitation on how to set the number. The block producer node 100 may assign a number to the applicant terminal device 1100 in the order of submission.

The block producer node (BP) 100 selects a winner corresponding to the applicant number corresponding to the above-mentioned remainder as a winner. In the following example, if the remainder is 2, an applicant having an applicant number 2 is determined as a winner.

The winning information also includes a winning method. The winning method is to calculate the remainder by dividing the number of applicants from the calculated hash value, and to select an applicant corresponding to the applicant number corresponding to the remainder as a winner, and a detailed description of the winning method has been described above.

By disclosing this winning method, it is possible to exclude the possibility of random manipulation in the winner's decision process. In addition, the organizer can prevent the contract from defaulting or delay the delivery of winnings.

If the selected winner cannot receive the prize or the winner transmits the information including the intention of receiving the prize to the administrator server, the block producer node selects a candidate to receive the prize. .

The block producer node (BP) first determines the order of candidates to receive the winning prizes in the order of the highest application amount, if the number of entries of the candidates is the same, and if the number of entries of the candidates is different, the number of entries is small. Determine the order of the candidates who will receive the winnings in order.

The application amount is the amount bet at the time of entry, and the number of application is the number of times the event was submitted.

In the above order, the amount of winnings for each of the candidates is determined by multiplying the winners' winnings, the winnings turnover ratio, and the winnings taking over ratio.

The winnings are the winnings that the winner must originally receive, for example, 100 million won.

The winning turnover ratio is the ratio of the number of entries of the winner to the number of entries of the winner and the candidate. The winner's original winnings will decrease as the winnings multiplied by the winning percentage. If three winners, nominee 1, nominee 2, nominee 3, nominee 4, nominee 4 and nominee 2 have entered, the winning percentage is 10 / (10 + 2 + 50% of 1 + 4 + 1 + 2) * 100.

The winning acceptance rate is the ratio of the number of entries of any one candidate to the number of entries of all the candidates. For example, if there are 5 candidates, candidate 1 twice, candidate 2 once, candidate 3 four times, candidate 4 once, candidate 5 twice, and the candidate 1 can take over 20% which is 2 / (2 + 1 + 4 + 1 + 2) * 100. In a similar manner, candidate 2's acceptability ratio is 10%, candidate 3's acceptability ratio is 40%, candidate 4's acceptability ratio is 10%, and candidate 5's acceptability ratio is 20%.

Accordingly, the amount of winnings for each of the candidates is calculated by multiplying the winnings, the winning turnover ratio and the winnings taking over ratio.

For example, the winning amount is 10 million won, which is multiplied by 100 million won of winnings and 50% of possible winnings and 20% of candidates taking over. In the same way, candidate 2's winnings are KRW 5 million, candidate 3's winnings are KRW 20 million, and candidate 4's winnings are KRW 5 million. Candidate 5's winnings are KRW 10 million.

That is, the original winner is previously set how to distribute the winnings to other candidates in a situation where it is difficult to receive the winnings, thereby providing clarity in the distribution of the winnings.

The block producer node (BP) is characterized in that when a particular candidate fails to take over the winning amount, the winning amount is distributed to the candidates in proportion to the application amount of the remaining candidates.

In the above example, if candidate 5 among the five candidates is difficult to receive the winning amount, the winning amount of 10 million won is distributed to the remaining four candidates.

If candidate 1's entry amount is 1,000 won, candidate 2's entry amount is 1,000 won, candidate 3's entry amount is 2000 won, and candidate 4's entry amount is 1,000 won, candidate 5's takeover amount will be 1/1. 5 million won will be distributed. Calculating in the same way, candidate 2 is 1/5 million won, candidate 3 is 4 million won is distributed to candidate 4 candidate 4 million won.

If even a particular candidate fails to take over the winning amount, the method of allocating the winning amount is pre-set to provide clarity in the prize allocation.

The block producer node (BP) selects the user with the highest number of entries during the specific time period of the application period as the excellent user. The user with the highest number of entries during the specific time is selected as the best user when the amount of entries is also highest.

The block producer node (BP) generates a block including winning information, and if it does not receive a transmission result from the applicant terminal device within 1 hour from the time of transmission, the manager terminal outputs green light on the display of the manager terminal device. Send a light command to the device. Although not shown in FIG. 1, the manager's terminal device is a terminal device possessed by a manager of a block producer node (BP). It is apparent that the terminal device of the manager communicates with the transmitter 400 in a wired or wireless manner.

The block producer node (BP) transmits a light emitting command to the terminal device to output yellow light on the display of the terminal device of the manager when the transmission result is not received within 1 hour or 2 hours after the transmission time of the transmitted message.

The block producer node (BP) transmits a light emitting command to the terminal device to output an orange light on the display of the terminal device of the manager if the transmission result is not received within two hours and three hours after the transmission time of the transmitted message.

The block producer node (BP) sends a light emitting command to the terminal device to output a red light on the display of the terminal device of the manager if the transmission result is not received within 3 hours and 4 hours after the transmission time of the transmitted message. .

The block producer node (BP) outputs a colored light with high visibility from the manager's terminal device as the time for which the transmission result has not been received from the transmission time of the transmitted message is increased. It is easy to recognize that the owner of the terminal device is in a serious situation that the terminal device cannot be handled. In addition, since the block producer node (BP) informs the administrator by dividing into four situations over time, the administrator can easily recognize the elapsed time according to the color output from the terminal device.

In other words, the block producer node (BP) can simply measure the status of the user who participated in the event by simply notifying the winning result.

All applicant terminal devices 1100 illustrated in FIG. 1 may check a winner through a block 900 transmitted by a block producer node (BP) 100. At this time, the block producer node (BP) 100 also transmits the winning information to the bank server device 2100. The bank server device 2100 transfers the winning amount to the winner included in the winning information. At this time, the bank server device 2100 performs a signature according to the winning amount remittance with a private key generated by itself. In addition, when the winning address is the address on the blockchain, the operator node executes the code disclosed to perform cryptocurrency transfer.
