Description

  The present invention relates to a distributed ledger apparatus, a distributed ledger method, and a broadcast apparatus and method of transaction information for managing identification of a user and controlling the flow of tokens in a block chain.

  Blockchains can be applied to various technical fields, but ICO (Initial Coin Offering) facilitates fundraising and has been developed as a technology for realizing cryptographic currency (or virtual currency). The For example, bitcoin is also achieving the same value as a currency without using a third party such as a central bank, unlike a common currency, by using blockchain technology. Before inventing the blockchain, in order to make electronic money to replace the currency, it was necessary to "middlemen" to guarantee its value and manage the transaction record of the currency. However, using a blockchain, the following structure allows a specific cryptographic currency to function as the actual currency without the need for a third party.

  (1) The blocks are sorted in time units, and the blocks include the transaction record and the connection information for the previous block, so it is difficult to forge and alter.

(2) By adopting a distributed ledger structure, the transparency of transactions is high and duplicate payments are difficult.
For the reasons mentioned above, cryptocurrency has become able to function as a currency. Various cryptocurrencies having such attributes, such as Bitcoin, Litecoin, Ripple, Etherium, Dash, Monero, etc., have been issued to the public. In particular, at present, large-scale funding (fundraising) is performed on a specific token via ICO (Initial Coin Offering). As described above, although various cryptocurrency currencies are issued, they are divided into those mainly used and those not so used due to the network effect.

  Also, various applications using block chains have been tried. For example, international remittance services such as Sentbe, Align Commerce, Moin, letters of credit transaction services verified by Bank of America and HSBC Holdings (HSBC Holdings plc, etc.), various types of financing, Power distribution services, content services such as Stememit and Streamium, notary services such as NEM, copyright management services such as Blockai, commodity transaction tracking services such as Everledger, contract management and execution services of Visa and Docusign .

  Such Smart Contract Code (Code), for example, in the case of Ethereum, is used as a language of Solidity, Serpent, LLL, Mutan, but is currently Solidity ( Solidity) is mainly used, and its syntax is similar to JavaScript (JavaScript (registered trademark)). Smart Contract is program code that is processed by the processing module 11 including “variables”, “structures” and “functions”. Such smart contract code (Smart Contract Code) is converted into byte code (Byte Code) through a compile process. Byte code is compiled using Solidity Realtime Compiler. Solidity's byte code (Byte Code) is all a hexadecimal code, and in Solidity, this byte code (Byte Code) is assigned to Payload (data :) type without a receiving address. If you distribute a transaction (Blockchain) to a blockchain (Blockchain), a minor (Minor) generates a block (Block), and such a transaction (Transaction) is regarded as a contract creation transaction (Contract Creation Transaction), and the transaction Control of receipt (Transaction Receipt) Contract Address: The address of the generated Contract is placed in the field, and the process returns.

  A Smart Contract development environment can include a range that includes development tools and a compiler. For example, in the case of Solidity, when a code is created and compiled, all compilers are required to use "Byte Code", "Function Signature", "Application Binary," and so on. Output interface (Application Binary Interface, ABI).

  The byte code (Byte Code) is a result of compiling the Smart Contract Code as described above, and when a Contract Creation Transaction (Contract Creation Transaction) is generated and placed in a block chain (Blockchain), Distributed ledger device (1, Ethernetium) depending on when a message transaction (Message Tx: Message Transaction) to a contract (Contract) occurs and when a call / query (Call / Query) to a contract (Contract) occurs In the case of EVM).

  A function signature (Function Signature) is used as an interface when calling a contract function, and is a 4-byte hash value obtained by hashing the contract function name with a SHA-3 cryptographic hash function. When executing a function of Contract (Contract), the To: address of Transaction (Contract) contains the Contract Address, and the data: portion contains 4 bytes of this method signature (method signature) and the parameter value as a payload ( Enter Payload.

  Application Binary Interface (ABI) means Application Interface written in a manner independent of a specific language or platform. The definition of ABI is output by a compiler or ABI generator (ABI Generator), but the ABI defines metadata of functions and parameters of a Smart Contract (Smart Contract). When creating a JavaScript (JavaScript) language-based application using ABI, you can create an object so that functions of Contract can be called simply by calling the method of that object Can be Currently Ethereum (web) 3. Support to create and use objects easily using ABI in JavaScript (JavaScript) application together with js, and Go-Esariam (Ethereum) 1.4.0 or later, Go Native language-based application ABIGen provides ABIGen to generate Go Code based on ABI, so that Smart Contract can be easily bound.

  Such smart contract (Smart Contract) development environment is linked with a block chain engine (Blockchain Engine) to create Contract Creation / Deployment, Message Transaction (Message Tx), Call (Call) / Query (Query) Query) can be transmitted, but such a block chain engine (Blockchain Engine) means the distributed ledger device 1 according to one embodiment of the present invention, and in the example of Etheriam Parity), which means Ethereum Node such as S (eth). Finally, a virtual machine such as EVM for transaction processing and Contract execution associated with all Smart Contracts is on a node such as Distributed Ledger Device 1. Is configured.

In such a Smart Contract development environment, ABI can be linked with Applications. Smart Contract owns only Logic and needs an Application for interaction with the user or an external system.
Application such as Html + CSS + JavaScript, application server (Application Server), wallet (wallet) is configured to interact with Smart Contract via, for example, the interface with Etherium (Ethereum) It is.

  Smart Contract Code (Smart Contract Code) is roughly divided into "Creation / Deployment", "Invoke by Message", and "Call". The code of the identification information management contract account according to one embodiment of the present invention is also roughly classified into contract account generation, identification information storage by message transaction, and identification information confirmation by query.

  Identification information (reference identification information and confirmation identification information) according to an embodiment of the present invention may mean information related to user identification, such as digital wallet information, e-mail information, social network ID, and the like. Since the identification information is stored in the form of transaction information in a block by the memory module 12 according to an embodiment of the present invention, it is difficult to forge or falsify the identification information, it is possible to clearly grasp the identification information recording time, user identification It is effective to be able to control the flow of tokens automatically.

The identification information management contract is a kind of smart contract, and can mean program code stored in the block chain of the memory module 12 and executed by the processing module 11. When it is requested to the distributed ledger device 1 according to one embodiment of the present invention in the form of a message transaction (Message Transaction) which causes the storage of reference identification information to change the global state, such transaction is Identification information management contract account address information shown in FIG. 4, identification information storage execution instruction, and a parameter (parameter) of the instruction from a specific EOA (Externally Owned Account) or a specific CA (Contract Account) to the address of the identification information management contract account It can be transmitted including reference identification information which is any one of the above, and other value information (Value) or parameters to be transmitted.

  The value information or parameter included in transaction information of storage of identification information according to an embodiment of the present invention may include a variable for black listing or white listing of the identification information. . The blacklisting request is a request provided by the user for the specific account when the confirmation identification information received in the query receiving step corresponds to at least one of the reference identification information. It can be meant to be returned to the user's digital wallet address. The whitelisting is generated when a smart contract code of the specific account is executed when the confirmation identification information received in the query receiving step corresponds to at least one of the reference identification information. May be stored in the distributed ledger and distributed to the blockchain distributed network.

  The value information or parameter included in transaction information for storing identification information according to an embodiment of the present invention may further include token issue amount condition information corresponding to the reference identification information. The use of such token issue amount condition information can be taken as an example when an ICO (Initial Coin Offering) is made public for a specific coin. For example, if it is desired to specify the limit (minimum or maximum) of Coins that can be purchased in the case of ICO to a specific user, the token issuance amount corresponds to the identification information in the identification information storage transaction information according to one embodiment of the present invention Condition information can be further input.
