Technology and life sciences are leading.

Among the technologies of the 4th industrial revolution, Blockchain is attracting attention as a major technology. Blockchain is a technology that provides security as a public transaction ledger. These blockchains are attracting attention, and the Bitcoin platform and ethereum platform, which are blockchain-based cryptocurrency technologies, are also attracting attention.

Bitcoin refers to a cryptocurrency that can record transaction records by blockchain technology, and Ether of Ethereum refers to a cryptocurrency that can record additional information such as contracts as well as transaction technology. In particular, Ethereum is attracting more attention by supporting a smart contract function that can record separate information.

On the other hand, in sports, an individual or a team decides the game according to a set rule. In general, sports are conducted to determine a game, but not only whether the player wins or loses, but also the player's contribution to victory is also an important outcome factor. So, if a particular player has shown great skills, or if a particular player plays a crucial role in winning in a team match, then the particular player is referred to, for example, Most Valuable Player or Man Of the Match. It is also selected as.

On the other hand, with the development of the Internet, voting for selecting an MVP or Man of the Match in a sports event can be performed through web or application rather than mail or phone. Accordingly, it is possible to conduct sports voting more easily and more quickly.

In this way, sports voting conducted online must be accompanied by fairness. Therefore, there may be a need in the art for a system that ensures fairness of voting through sports voting based on a blockchain network.

1 is a diagram illustrating an example of a sports voting system in which various aspects of the present disclosure may be implemented.

Referring to FIG. 1, a sports voting system may include a blockchain network 100, a sports platform server 600, and an external server 700. However, the above-described components are not essential in implementing the sports voting system, and thus the sports voting system may have more or fewer components than the above-listed components.

In addition, the blockchain network 100, the sports platform server 600, and the external server 700 may mutually transmit and receive data for a sports platform service according to some embodiments of the present disclosure through a network.

Networks according to some embodiments of the present disclosure include Public Switched Telephone Network (PSTN), x Digital Subscriber Line (xDSL), Rate Adaptive DSL (RADSL), Multi Rate DSL (MDSL), Very High Speed (VDSL). Various wired communication systems such as DSL), Universal Asymmetric DSL (UADSL), High Bit Rate DSL (HDSL), and local area network (LAN) can be used.

In addition, the network presented here is CDMA (Code Division Multi Access), TDMA (Time Division Multi Access), FDMA (Frequency Division Multi Access), OFDMA (Orthogonal Frequency Division Multi Access), SC-FDMA (Single Carrier-FDMA) and Various wireless communication systems such as other systems can be used.

The network according to the embodiments of the present disclosure may be configured regardless of its communication mode, such as wired and wireless, and is composed of various communication networks such as a personal area network (PAN) and a wide area network (WAN). Can be. In addition, the network may be a known World Wide Web (WWW), and may use a wireless transmission technology used for short-range communication such as infrared (IrDA: Infrared Data Association) or Bluetooth (Bluetooth).

The techniques described herein may be used not only in the networks mentioned above, but also in other networks.

According to some embodiments of the present disclosure, the blockchain network 100 may include a master node 110 and a plurality of user nodes 120. However, the above-described components are not essential for implementing the blockchain network 100, and thus the blockchain network 100 may have more or fewer components than the components listed above.

The term “node” used in the present disclosure may be any type of computing device such as a server or terminal capable of exchanging data with at least one of a “master node” and a “blockchain network”. However, the present invention is not limited thereto, and the node may be any device capable of exchanging data between a plurality of nodes.

According to some embodiments of the present disclosure, a plurality of nodes included in the blockchain network 100 may include a full block chain node and a light weight node.

A full block chain node can contain all block information from the first block of the block chain to a block that is currently newly created. In addition, the full blockchain node collects and stores all blockchain information, and can verify the received block to add a new block.

The lightweight node does not have the original of all block information, and may include only header information. In order for the lightweight node to verify the transaction, it can perform Simple Payment Verify (SPV).

For example, a lightweight node can request block information from a full blockchain node, and the authentication content of a transaction can be verified through Merkle Root.

However, for convenience of explanation, a plurality of nodes included in the blockchain network 100 may be described below assuming that they are full blockchain nodes.

In addition, the term “block” used in the present specification is a unit stored in a blockchain network, and can form a block chain by being connected to adjacent blocks. When the information of the master node 110 and the content related to the information of the blockchain network 100 are issued as a transaction to the blockchain network, it may be included in a block in the corresponding transaction and recorded in the blockchain network. Depending on the settings of the blockchain network, the right to read, the right to consensus, and/or the right to verify the data stored in the block can be determined.

Smart contracts according to some embodiments of the present disclosure are written in a digital language for contracts related to sports event creation (eg, conditions for participation in sports events, conditions for team creation, whether rewards for sports events or whether to record sports results, etc.) It can run on any computing device. That is, when the code and/or function included in the smart contract is executed, any type of contract according to the embodiments of the present disclosure (e.g., determining whether to participate in a sports game, creating a team, providing a reward, or playing a sports game) Result recording, etc.) can be implemented.

A smart contract according to some embodiments of the present disclosure includes a method of creating a new smart contract, a method of executing a function on a specific smart contract, or a method of transmitting a coin operable in the blockchain network 100. It can be implemented by at least one. In addition, smart contracts can be executed by transactions or other contracts generated by externally owned accounts.

The smart contract for creating a contract related to the creation of a sports event according to some embodiments of the present disclosure performs a transaction in order to prevent malicious code such as, for example, infinite repetition and to ensure the integrity of data related to the contract related to the creation of a sports event. It can also be stipulated to pay specific execution costs when executed. The execution cost here may mean any type of coin that can be traded in the blockchain network 100 or a separate type of medium (eg, gas, etc.) that can be linked with the coin. As a non-limiting example, the base execution cost of the transaction may be set to 21,000 gas. For example, such execution costs may include the cost of processing the Elliptic Curve Digital Signature Algorithm (ECDSA) for the account address of the issuer of the transaction, the storage cost for storing the transaction, and the network bandwidth cost. If the smart contract is defined to pay a certain cost when executing the smart contract, malicious attacks such as infinite execution such as intentional DDoS attacks can be prevented.

In order to implement a contract related to creating a sports event according to some embodiments of the present disclosure, a call between smart contracts may be implemented using a structure called a message. For example, these messages can be generated by a contract account (CA), and can be delivered to other contracts when calling a function. In one embodiment, since the message in this case is generated and processed inside the blockchain network 100, unlike transactions that occur in externally owned accounts, separate execution costs such as gas may not be incurred.

In implementing a contract related to sports event creation according to some embodiments of the present disclosure, when synchronizing through a blockchain by including a function of a smart contract in a transaction in the form of a compiled code, the information included in the transaction is input to the function The smart contract can be implemented in a way that executes the function expressed as code and stores the result in a separate state.

When the contents of the function and the input of the function are shared by a smart contract shared in the blockchain network 100, the integrity of the data can be guaranteed even if the result of the function is not separately shared.

In a further embodiment, the computing devices constituting the blockchain network 100 of the present disclosure for executing a contract related to the creation of a sports event store a transaction storage database that changes the state of the smart contract and the latest state of the smart contract. You can also include a database of smart contracts that you are doing. In this case, a smart contract for the execution of a contract related to the creation of a sports event in the present disclosure may be defined as an application (eg, a sports platform application) that can change the state on the blockchain network 100, The state of the smart contract can be defined as a variable used in the application (i.e., sports platform application), and the input value for changing it is issued from at least one of the master node 110 or a plurality of user nodes 120 Can be included in the transaction.

In a further embodiment, the database storing the state of the smart contract may be combined with the database storing the transaction to achieve a high compression rate. In addition, in order to achieve the distributed consensus of the database storing the state of the smart contract and low dependency of the smart contract, it can operate separately from the database storing the transaction.

A plurality of nodes included in the blockchain network 100 may share and store generated transactions and/or smart contracts through the network. In addition, a plurality of nodes can perform a function of recording a transaction in a block when the verification of the transaction and/or smart contract is completed through the consensus algorithm of the blockchain technology.

According to some embodiments of the present disclosure, the consensus algorithm performed in the blockchain network 100 is: PoW (Proof of Work) algorithm, PoS (Proof of Stake) algorithm, DPoS (Delegated Proof of Stake) algorithm, PBFT (Practical Byzantine Fault Tolerance) algorithm, Delegated Byzantine Fault Tolerance (DBFT) algorithm, Redundant Byzantine Fault Tolerance (RBFT) algorithm, Sieve algorithm, Tendermint algorithm, Paxos algorithm, Raft algorithm, PoA (Proof of Authority) algorithm and/or PoET (Proof of Elapsed Time) algorithm may be included.

Since the consensus algorithm of the blockchain technology is used to record smart contracts and/or transactions including content related to game creation in a block, the effect of preventing forgery or alteration of information related to game generation is generated.

Meanwhile, a block chain network structure according to some embodiments of the present disclosure may be of a public type or a private type. In the case of a public blockchain network, there is a disadvantage of inefficient in terms of consensus time, transaction processing speed, and efficiency of use of computing resources, as all nodes must perform verification in order to verify a transaction. Because it is possible, there may be advantages in the transparency and integrity of the stored data. In addition, in the case of a private (or consortium) block chain, since the operating entity is clear, there is an advantage of being efficient in terms of consensus time, transaction processing speed, and efficiency of use of computing resources, but transparency about the transaction processing process and results. There may be advantages in terms of

The consensus algorithm in some embodiments of the present disclosure may be a private or consortium-type blockchain network, but is not limited thereto, in order to improve the user experience through efficient use of computing resources and increase in transaction processing speed. Depending on the implementation, public type may be used as the consensus algorithm when it is desired to further emphasize the transparency of transactions or smart contracts.

According to some embodiments of the present disclosure, among the plurality of user nodes 120 of the blockchain network 100, the first user node 121 masters a smart contract including contents related to the creation of a sporting event written by the user. It can be transmitted to the node 110. Specifically, the first user node 121 may generate a smart contract that can be operated on the blockchain network 100 using an arbitrary language such as Solidity and transmit it to the master node 110.

Meanwhile, each of the plurality of user nodes 120 included in the blockchain network 100 may verify the smart contract received from the master node 110 through a consensus algorithm. Further, each of the plurality of user nodes 120 may generate a block when the smart contract is verified through a consensus algorithm, and record the smart contract in the block.

Specifically, the smart contract extracts a nonce value that satisfies a preset condition by any one of the plurality of user nodes 120, and the consensus algorithm when the nonce value is recognized as valid in each of the plurality of user nodes 120 It can be recognized that it has been verified through. Here, the preset condition may be satisfied when the hash value of the block generated when the information stored in the header of the block and the nonce value are converted through a hash algorithm is less than the difficulty value of the block.

According to some embodiments of the present disclosure, a specific user node of the blockchain network 100 may transmit a smart contract call signal (query) to the master node 110. Specifically, the specific user node may transmit a smart contract call signal including a contract address of the smart contract generated by the first user node 121. Here, the specific user node may be a node of a user who has participated in a sports event in response to a smart contract including content related to the creation of a sports game generated by the first user node 121.

According to some embodiments of the present disclosure, the contract address of the smart contract may be formed in hexadecimal. However, the present invention is not limited thereto, and the contract address of the smart contract may have various forms.

According to some embodiments of the present disclosure, the processor 112 of the master node 110 may search for a smart contract on the blockchain network 100 through a contract address included in a smart contract call signal (query). In addition, the master node 110 may provide a reward corresponding to the discovered smart contract to a specific node.

As described above, in relation to the operation in which the processor 112 transmits a signal (query) to search for a smart contract, the communication unit 111 of the master node 110 can transmit the inquiry query to the blockchain network 100. In addition, the node receiving the query from the blockchain network 100 may perform a response to the query. In the case of such an inquiry (query) operation, since values stored in the blockchain network can be inquired without changing the blockchain data, the blockchain network 100 does not need to be synchronized separately. Therefore, the node of the blockchain network 100 can check its own DB by responding to a corresponding inquiry (query) and perform a quick response regardless of block synchronization.

The information inquiry query in the present disclosure may be used to search information recorded on the blockchain network 100. Transactions and/or smart contracts in the present disclosure are used to insert new data into the blockchain network 100 or update (modify/change/delete/add) data recorded on the blockchain network 100. Can be used.

In addition, the master node 110 may generate a transaction as a reward corresponding to the smart contract is provided to the specific node. Here, the transaction may include content provided with a reward to a specific node.
