It is related to the configuration diagram showing the components of the transaction history tracking type white coin transaction forming device (1) consisting of the white coin transaction mediation module and AOS type blockchain module, which is issued by public organizations (government, enterprises, organizations) After one public fund is verified in the blockchain, it is converted into a white coin, and the transaction history of the white coin is transacted with a white coin between the public fund provider and the public fund consumer, or between the public fund consumer and another public fund consumer. It is configured to track and control the movement path.

The transaction history tracking type white coin transaction forming apparatus 1 is more specifically, an application module 100 for public fund providers, a white coin transaction brokering module 200, and an AOS (Append Only Storage) type blockchain module 300. , It consists of an application module 400 for public fund consumers.

First, the application module 100 for a public fund provider according to the present invention will be described.

The application module 100 for the public fund provider is connected to the white coin transaction intermediary module through a wired / wireless communication network, requests a certificate check toward the white coin transaction intermediary module, and when authentication is completed, the public organization toward the white coin transaction intermediary module (government, enterprise) , Group) sends a request for verification of the smart contract regarding public funds, business information about public funds, and public fund transaction contract data, and inputs the verification completion signal of the AOS (Append Only Storage) blockchain module accordingly When it does, it plays a role of performing an application module for public fund consumers and a white coin transaction related to public funds through the white coin transaction brokerage module.

It consists of either a server computer or a smart device from a public fund provider.

Here, public funds are funds issued by public organizations (government, corporations, and organizations) and are generated in units of 100 million to 1 trillion.

The project information on the public fund includes both national support project information and national R & D project information.

In addition, the public fund transaction contract data refers to a contract for public fund operation and business between an application module for a public fund provider and an application module for a public fund consumer.

In addition, when the application module for the public fund provider sends a whitecoin tracking request signal to the whitecoin transaction intermediary module, the whitecoin transaction intermediary module sends a whitecoin tracking request signal to the AOS (Append Only Storage) type blockchain module. As a response signal, it is configured to receive a smart contract that includes whitecoin tracking result data regarding the transaction history and movement path of the whitecoin.

Next, the white coin transaction brokering module 200 according to the present invention will be described.

The white coin transaction brokering module 200 is located between the application module for the public fund provider and the application module for the public fund consumer, and after checking the certificate of the application module for the public fund provider and the application module for the public fund consumer, The smart contract requested by the application module for the certified public fund provider and the smart contract requested by the application module for the public fund consumer are sent to the AOS (Append Only Storage) type blockchain module for verification and verification, and the smart of the verified application module for the public fund provider By receiving the contract and the converted white coin based on the smart contract, between the application module for the public fund provider and the application module for the public fund consumer, or between the application module for the public fund consumer and the application module for the public fund consumer It serves to broker transactions.

3, the certificate check unit 210, the shared block generation unit 220, the shared block delivery unit 230, the block chain verification completion data transmission unit 240, the white coin transaction broker 250 It consists of.

First, the certificate checking unit 210 according to the present invention will be described.

The certificate check unit 210 serves to check whether the application module for the public fund provider, the application module for the public fund consumer, is the authorized application module for the public fund provider, or the application module for the authorized public fund consumer.

Second, the shared block generator 220 according to the present invention will be described.

The shared block generation unit 220 performs a white coin transaction with the smart contract requested by the application module for the public fund provider that has been authenticated through the certificate check unit, the smart contract requested by the application module for the public fund consumer, and the application module for the public fund consumer. At the same time, the generated smart contracts are stored in Append Only Storage to generate a shared block of Append Only Storage.

This consists of the identification number (sid) given by the blockchain network, smart contract issuance information (data), block creation time (timestamp), certificate issuing country name (country), and the most recent HASH value (pre_HASH) of the book table.

Here, the Append Only Storage occurs when the smart contract requested by the application module for the public fund provider, the smart contract requested by the application module for the public fund consumer, and the white coin transaction with the application module for the public fund consumer It does not allow modification and deletion of the old smart contracts and data, and serves to connect them to one and store them in a state without change.

As illustrated in FIG. 4, the shared block generation unit 220 is composed of a white coin-type merkle tree unit 221 and a block generation cycle control unit 222.

[White Coin-Type Merkle Tree (221)]

The white coin-type merkle tree unit 221 generates all digital fingerprints for the entire set of transactions, in order to summarize all the transactions (= transaction history for each coin, the movement path of the coins) contained in the corresponding block. It serves to verify whether it is included inside the block.

Here, the Merkle tree, also called a binary hash tree, refers to a data structure used to efficiently summarize and verify the integrity of a large data set.

The Merkle Tree is used by Whitecoin to summarize all transactions within a block, and it creates a very efficient process for generating all digital fingerprints of the entire set of transactions and verifying whether a particular transaction is contained within a block.

Create a Merkle tree by repeatedly hashing a pair of nodes until there is one hash called the root or Merkle root.

White Coin's Merkle Tree consists of a double SHA256 type cryptographic hash algorithm engine.

In the Merkle tree, N data elements are hashed, and when summarized, a maximum of 2 * log₂ (N) operations are required to find out whether a specific data element is included in the tree, thus creating a very efficient data structure.

That is, in order to prove that a specific transaction is included in a block, the path size (hash) is an authentication path or a Merkle path (where a node generates log₂ (N) 32-byte hashes and connects a specific transaction with the root of the tree). merkle path).

This can be used efficiently when the number of transactions increases.

The reason is that the value of log ₂ (N) increases much more slowly.

Accordingly, when the Whitecoin node efficiently produces 10 or 12 hashes (320 to 384 bytes), the number of cases increases to prove one transaction out of 1,000 transactions within a megabyte-sized block. You can do it.

[Block creation cycle control unit 222]

The block generation period control unit 222 serves to control to generate a block of white coins every 5 to 20 minutes on average.

This is the heartbeat of White Coin, and based on this generation cycle, the frequency of currency issuance and the rate of settlement of transactions are determined.

This may also change the number of participants participating in mining and the computers they use.

In order to maintain the creation time of the block from 5 minutes to 20 minutes, the difficulty level of the white coin-type mining part is configured in consideration of the above changes.

In fact, the difficulty level is a dynamic parameter, and is set periodically to meet the target value of blocks generated every 5 to 20 minutes.

That is, the target value of difficulty is set to a value in which the mining ability has a block generation time of 5 to 20 minutes.

Number of transactions	Block size	Path size (hash)	Path size (bytes)
14 cases	4 KB	4 hashes	128B
452 cases	128KB	9 hashes	288B
1,848 cases	512KB	11 hashes	352B
64,567 cases	16 MB	16 hashes	512B

As shown in Table 1, while the block size rapidly increased from 14 KB to 4,64,567 transactions to 16 MB, the Merkle path needed to demonstrate whether the transaction was included in the block was 128 to only 512 bytes. It can be seen that it increases slowly. With the Merkle Tree, nodes simply download block headers (80 bytes per block) and retrieve transactions from the full sized Merkle path from a full node without the need to store or transmit massive blockchains that may be tens of gigabytes. You can check whether it is included.

A simple gibble verification (SPV) node, a node that does not store a full blockchain, can verify transactions without downloading the full block using the Merkle path.

Here, the simple payment verification (SPV) node does not have a function for storing all the full blockchain in all nodes.

Many public funding application modules are configured to run on space-constrained or power-constrained devices such as smartphones, tablets, and embedded systems.

In these devices, it is configured to operate without storing the full blockchain using the simple payment verification (SPV) method.

The SPV node downloads only the block header, not the transactions in the Gaga block.

As the adoption of white coins rapidly increases, SPV nodes become the most common form of white coin nodes, especially white coin wallets.

Third, the shared block delivery unit 230 according to the present invention will be described.

The shared block delivery unit 230 AOS the smart contract of the application module for public fund providers and the smart contract of the application module for public fund consumers generated by the shared block generator through the shared block generation unit. It serves to deliver to the (Append Only Storage) type blockchain module.

This consists of the identification number (sid) given by the blockchain network, smart contract issuance information (data), block creation time (timestamp), certificate issuing country name (country), and the most recent HASH value (pre_HASH) of the book table.

Fourth, a description will be given of the blockchain verification complete data transmission unit 240 according to the present invention.

The blockchain verification completion data transmission unit 240 serves to transmit the verified smart contract from the AOS (Append Only Storage) type blockchain module to the application module for the public fund provider and the application module for the public fund consumer.

Fifth, the whitecoin transaction intermediary 250 according to the present invention will be described.

The whitecoin transaction brokerage unit 250 receives the smart contract of the application module for the public fund provider, which has been verified from the AOS (Append Only Storage) type blockchain module, and the converted white coin based on the smart contract, and the public fund It acts as a proxy for the supplier's application module and brokers the transaction with the application module for public fund consumers.

This is a value for public business execution and results to the application module for public fund consumers connected to the selected blockchain network, which is one of P2P, P2C, and C2P, and is configured to broker transactions by issuing white coins.

In other words, if the public fund issued by the government, business, or organization is 300 million won, 3000 white coins (1 = 100,000 won) will be issued from the AOS (Append Only Storage) type blockchain module.

The whitecoin transaction brokerage unit calculates the deposit interest of real money converted into white coins into a profit structure, calculates the whitecoin transfer fee, and then distributes the revenue to distribute to the application module for public fund providers or to the application module for public money consumers. The control unit is included and configured.

Here, the deposit interest of real money converted into white coins is handled by the bank management server, and the whitecoin remittance fee is handled by the whitecoin transaction brokerage module.

In other words, the whitecoin transaction brokerage unit is connected to the bank management server, and when the application module for public funds requests the actual currency exchange for the white coin, the whitecoin transaction brokerage unit exchanges the actual currency for the white coin to the bank management server. It consists of a structure that requests, receives the actual currency accordingly, and delivers it to the application module for public fund consumers through the bank management server itself or the whitecoin transaction brokerage.

Next, the AOS (Append Only Storage) type blockchain module 300 according to the present invention will be described.

The AOS (Append Only Storage) type blockchain module 300 is composed of a number of cell-type verification clients in a mesh structure, and is transmitted in the form of a shared block from the whitecoin transaction brokerage module through a distributed storage-based data forgery prevention technology. , Verify whether the public contract transaction data included in the smart contract, the whitecoin supply request data according to the public fund, the whitecoin transaction approval data according to the public fund, and the use of whitecoin data are properly written, and create block and link between blocks. While in charge, based on the smart contract of the application module for the public fund provider, it is converted to white coin, and according to the tracking request signal of the white coin transaction intermediary module, the transaction history and movement of the white coin used in the application module for the public fund consumer It serves to track and control the route.

5, the API interface unit 310, a block file storage unit 320, a white coin conversion unit 330, a white coin-type key encryption setting control unit 340, and a virtual machine. It consists of a (Virtual Machine) unit 350, an artificial intelligence white coin tracking control unit 360.

First, the API interface unit 310 according to the present invention will be described.

The API interface unit 310 is connected to the whitecoin transaction brokerage module and the API interface network to form a whitecoin transaction brokerage module, an insert interface, and a read interface.

Second, the block file storage unit 320 according to the present invention will be described.

As shown in FIG. 6, the block file storage unit 320 is a smart contract of an application module for a public fund provider that is a shared block from a whitecoin transaction brokerage module connected to an API interface network through an API interface unit. Wow, it serves to collect and store smart contracts of application modules for public fund consumers.

This includes and stores smart contracts related to white coins converted through the white coin conversion unit.

Third, the white coin conversion unit 330 according to the present invention will be described.

The white coin conversion unit 330 retrieves public fund data included in the smart contract of the application module for the public fund provider, which is a shared block stored in the block file storage, and converts it into white coin according to the usage It plays a role.

It is formed by dividing public funds issued by governments, corporations, and organizations into 1,000 to 1,000,000,000 won depending on the usage.

Here, the white coin is a digital currency or digital coin, which includes system structure information as a digital document, and includes transaction party information in a transaction, and the transaction information is configured to be disclosed in an authorized object.

A smart contract for the white coin converted through the white coin conversion unit is generated and stored in the block file storage unit.

Fourth, the white coin-type key encryption setting control unit 340 according to the present invention will be described.

The white coin-type key encryption setting control unit 340 serves to control to set public key-based encryption on the white coin converted through the white coin conversion unit.

It is configured to set and control key encryption so that transactions can be made by trading between white coin e-wallet holders among application modules for public fund consumers.

As shown in FIG. 7, all whitecoin users have a pair of key values consisting of a public key serving as an address and a private key used for digital signature upon transaction approval.

The private key (k) is composed of numbers, and is usually randomly extracted.

The first and most important step in the process of generating a private key is to find a highly secure entropy source, that is, randomness.

Whitecoin software uses a basic operating system random number generator to generate 256-bit entropy.

In other words, the task of generating a white coin key is, for example, to throw a coin up 256 times to determine a binary number constituting a random private key that can be used in a white coin wallet.

Ownership and control of the private key is the key to user control over all money associated with the white coin address corresponding to the private key.

If you prove the ownership of the money used in the transaction, you will be able to consume the white coin, and at this time, use the private key to sign the necessary.

The private key should never be disclosed to others.

This is because releasing a private key to a third party is equivalent to passing control over a white coin secured with the private key.

The public key K is generated from the private key using an elliptic curve addition function, which is a one-way encryption function.

Since calculation works only in one direction, the private key can be converted into a public key, but the public key cannot be converted into a private key.

Similarly, a white coin address (A) is generated from the public key (K) using a one-way cryptographic hash function.

The address generated from the public key is identified in the form of a combination of random numbers and letters, and each address is composed of the balance, the transaction history for each coin, and the movement path of the coin.

The whitecoin address can be shared with whitecoin users who use the whitecoin address to send the whitecoin directly into the wallet of the counterparty like an email address.

The difference from email addresses is that users can create as many new addresses as they like, and receive money transfers to all the whitecoin addresses created.

There is practically no limit to the number of addresses a user can create.

The key value is not actually stored on the network, and the user creates and stores it in a file, usually in a structured file or in a simple database in an electronic wallet.

The key in the user's wallet is completely independent of the Whitecoin protocol, and can be created and managed by the user's wallet software without reference to the blockchain or Internet access. In fact, wallets can be said to be a key chain containing a private / public key pair.

Users sign their transaction using a key, proving that they own the transaction output (white coin).

Whitecoins are stored in the blockchain in the form of transaction output values (commonly known as vout or txout).

In other words, the key here enables the interesting properties of Whitecoin, such as decentralized trust and management, proof of ownership, and cryptographic-proof security model.

Fifth, the virtual machine unit 350 according to the present invention will be described.

The virtual machine (350) is a mining (mining, mining) operation that gives a proof of work (proof of work) to approve the block, and the smart contract and data stored in the block file storage (Block File Storage) It does not allow modification and deletion, and performs the functions of data verification, block verification, block sync (synchronization), monitoring, and data inquiry while connecting and functioning as an append-only storage without change. Do it.

It is connected to the outside only through the API interface part, and the root authority and admin authority are sealed in the system, so that only two ports (for web services and blockchain-only services) are opened.

In addition, it is driven only by a predefined function, and it is a virtual appliance type and physically exists as only one virtual server file. The internal block file has a characteristic that is not destroyed unless the virtual server itself is removed.

The virtual machine unit 350 includes a white coin-type mining unit 351.

As illustrated in FIG. 8, the white coin-type mining unit 351 provides a proof of work for authorizing a block that is a set of account transfer transaction records of white coins on a P2P network. Mining).

That is, for example, by accrediting a block containing a transaction that has occurred for 10 minutes on a network according to specific conditions, it gives an effect of accrediting all transactions in the block, and then repeating the same process of making a block to repeat these blocks continuously. It repeats the process of maintaining the blockchain that continues.

Here, we have to look at two points: the subject who gives proof of work and how it works.

First, the subject that gives public confidence is called a miner in the white coin system.

In addition, the minor refers to a verification client in which a plurality of cell-type verification clients are made of a mesh structure and the verification clients approve the data processing requests coming into the blockchain network through an agreement process (= highly contributing miners first).

And the method of giving credibility is called mining, and these are called nodes from a computer network perspective, and the functional aspect is called a timeserver.

The Whitecoin protocol, a decentralized P2P network, includes built-in algorithms that define mining operations across the entire network.

 The difficulty of the processing work that the minor has to perform is dynamically adjusted to successfully record a block composed of transactions occurring in the white coin network.

In other words, on average, every 10 minutes, mining is successful regardless of how many miners (and CPUs) are doing mining.

Transactions sent over the network are not verified until they go up to the blockchain, a distributed ledger worldwide.

Here, some nodes on the whitecoin network are special nodes called miners mentioned above.

For example, suppose that a miner named “A” is running a mining league, a specialized computer hardware system designed for mining white coins, to mine white coins.

Miner's specialized mining hardware is connected to a server running a full white coin node.

Therefore, Aminer's node keeps a local copy of the blockchain, which is a full list of blocks created from the start.

If the current A miner's node consists of a chain of blocks up to 'Block # 277314', the Aminer's node collects transactions and shows a valid proof of work for the new block called 'Block # 277315', that is, proof of work ) Mining to find a solution for the algorithm that assigns (the hash value that satisfies a certain condition), and checks if there are any blocks found by nodes of other miners.

Here, if Miner's node receives a new valid 'Block # 277315' propagated on the Whitecoin network before effectively generating 'Block # 277315', someone else wins the competition in the minors and A loses It means that.

But the end of the competition marks the start of a new competition.

After the block arrives, the competition for 'Block # 277315' ends, and the competition where 'Block # 277316' is generated begins.

The miner calculates the hash value of a new block by entering a hash value of the previous block, an unacknowledged transaction record (encrypted message), and a random number called nonce.

While inputting the nonce differently, it is checked whether the calculated hash value satisfies the system requirement, that is, the condition that it should be lower than the set threshold. In the system, the more the miner, the higher the difficulty.

Sixth, the artificial intelligence-type white coin tracking control unit 360 according to the present invention will be described.

The artificial intelligence white coin tracking control unit 360 self-learning through machine learning and deep learning, and then uses white coin usage data included in the smart contract of the application module for public fund consumers according to the request signal of the white coin transaction brokerage module. Based on, after analyzing the transaction history pattern, it plays a role of tracking and controlling the transaction history and movement path of the white coin.

Here, as shown in FIG. 9, the transaction history and movement path of the white coin, the number of white coin transactions associated with a specific address, the balance held by the address, the total amount sent, the total amount received, the first transaction date, the last transaction date, and the transaction history , Trader information, trader's IP address, account information associated with the Whitecoin wallet, and transaction history and movement path for trader personal information.

It consists of a block chain explorer.

The block chain explorer provides services that allow you to see each step visually while tracking transactions through the whitecoin network and blockchain.You can find the whitecoin address, transaction history, blocks, etc. You can know the relationship and flow between them.

Each service can find related data on the whitecoin network and blockchain by searching for information such as the block number of the whitecoin address.

The artificial intelligence white coin tracking control unit self-learns the white coin usage data included in the smart contract of the application module for public fund consumers through machine learning and deep learning, and analyzes the collected data to track illegal transactions. Gives

 At this time, if you enter the date range and the amount range, it is configured to search for White Coin Transactions corresponding to those ranges.

Also, it analyzes the correlation between addresses, visualizes input / output by searching for all white coin transactions transmitted or received by a specific address, and clusters by finding relationships between addresses.

At this time, it is possible to trace the route between them by analyzing the relationship transmitted from one address to another.

By tracking the characteristics of the Whitecoin Transaction, known suspicious behaviors can be identified using Machine Learning to identify patterns, and unknown future suspicious behaviors can be predicted using Unsupervised Learning. It is composed.

The following describes the process of tracking the characteristics of White Coin Transaction for Machine Learning.

First, self-learning to find a link that connects white coin addresses and personal information.

This is to identify the suspect by identifying the suspect's white coin address converging to the final destination of the transaction flow by analyzing the relationship of the white coin addresses used by the criminal suspect as a means of crime (because multiple white coin addresses can be generated simultaneously). You need to find a route that you can.

Subsequently, whitecoin abuse criminals can often look at situations where people make as many addresses as they want, in order to conceal personal information as much as possible, which makes it difficult for transactions with the same person to be repeated again.

If you want more concealment of personal information, you can use the method of washing through a third party that mixes all the white coins into a pool and extracts a new address.

At this time, self-learning attempts to connect to a specific individual's address list through machine learning.

For example, this list of addresses can be obtained by using non-blockchain information, such as analyzing consumption habits or changing transactions sent from one address to another.

The artificial intelligence type white coin tracking control unit traces the public address of FIG. 10 (a) based on the data of the white coin included in the smart contract of the application module for public fund consumers, as shown in FIG. 10 (b) relates to an exemplary diagram in which patterns of transaction history related to a whitecoin transfer process are analyzed.

Next, the application module 400 for public fund consumers according to the present invention will be described.
