1 shows an example of a communication structure between a server and a user device.

In this specification, “server” is a kind of server that communicates with external devices (eg, user devices) or external servers (other than itself) through a network, and is used to operate external devices or external servers. can indicate a server for In one example, the server may be implemented using a web server program provided in various ways according to an operating system such as DOS, Windows, Linux, Unix, and Macintosh in general server hardware. Or, in one example, the server may be the same or similar device as the user device described below.

In one embodiment, the server 110 may refer to a device (part of the system) that provides an asset management service based on a blockchain through a metaverse. For example, the server 110 may be referred to by various names such as an operating server, a metaverse server, and a metaverse asset management platform.

In this specification, “user device” refers to smart phones, mobile phones, smart TVs, smart watches, electronic wristwatches, set-top boxes, tablet PCs, digital cameras, camcorders, laptop computers, desktops, electronic With a variety of devices including book terminals, digital broadcasting terminals, PDAs (Personal Digital Assistants), PMP (Portable Multimedia Players), navigations, MP3 players, wearable devices, air conditioners, microwave ovens, audio, DVD players, etc. can be implemented

In this specification, the server 110 and the user device 120 may mutually communicate through a communication network. The communication network may be, for example, a wireless communication network or a wired communication network. The wireless communication network may be, for example, a communication network based on Long Term Evolution (LTE), Radio Access Technology (RAT), New Radio (NR) RAT, WiFi, and the like.

In one example, the server 110 and the user device 120 may perform Device-to-Device (D2D) communication with each other and perform UU communication with a base station (eg, gNB and/or eNB). can do. In a time division multiple access (TDMA) and frequency division multiples access (FDMA) system for performing the D2D communication or the UU communication, accurate time and frequency synchronization may be required. If time and frequency synchronization are not accurate, system performance may deteriorate due to Inter Symbol Interference (ISI) and Inter Carrier Interference (ICI). In D2D communication according to an example, for time/frequency synchronization, a synchronization signal may be used in a physical layer and a master information block (MIB) may be used in a radio link control (RLC) layer.

In the process of D2D communication, the server 110 and the user device 120 are directly synchronized with GNSS (global navigation satellite systems), or via a terminal directly synchronized with GNSS (within network coverage or outside network coverage) It can be indirectly synchronized to GNSS. When GNSS is set as a synchronization source, the server 110 and the user device 120 may calculate a DFN and a subframe number using Coordinated Universal Time (UTC) and a (pre)set Direct Frame Number (DFN) offset. .

Alternatively, the server 110 and the user device 120 may be directly synchronized with the base station or synchronized with other terminals that are time/frequency synchronized with the base station. For example, the base station may be an eNB or gNB. For example, when the server 110 and the user device 120 are within network coverage, the server 110 and the user device 120 receive synchronization information provided by a base station and are directly synchronized with the base station. can After that, the server 110 and the user device 120 may provide synchronization information to other nearby terminals. When the base station timing is set as a synchronization criterion, the server 110 and the user device 120 use a cell associated with a corresponding frequency (when the frequency is within cell coverage), a primary cell, or a serving cell for synchronization and downlink measurement. (if outside cell coverage at the frequency).

A base station (eg, a serving cell) may provide synchronization settings for a carrier used for D2D or sidelink (SL) communication. In this case, the server 110 and the user device 120 may follow the synchronization setting received from the base station. If the server 110 and the user device 120 do not detect any cell on the carrier used for the D2D or SL communication and do not receive synchronization settings from the serving cell, the server 110 and the user device 120 may follow preset synchronization settings.

Alternatively, the server 110 and the user device 120 may be synchronized with other terminals that do not directly or indirectly acquire synchronization information from a base station or GNSS. Synchronization source and preference may be set in advance for the terminal. Alternatively, the synchronization source and preference may be set through a control message provided by the base station.

In one embodiment, the server 110 and the user device 120 may mutually communicate through the network 100 (or communication network). For example, when the server 110 transmits data to the network 100, the network 100 may deliver (transmit) the data to the user device 120. Alternatively, when the user device 120 transmits data to the network 100, the network 100 may transmit (transmit) the data to the server 110.

2 to 7 below, based on signal exchange or communication between the server 110 and the user device 120, the asset management system provides asset management services based on the blockchain through the metaverse. The method is reviewed in detail.

2 is a diagram for explaining a metaverse environment according to an embodiment.

Metaverse means a virtual space platform that enables real-life social, economic, educational, cultural, and scientific and technological activities through avatars. 2 shows an example in which the user uses/experiences/experiences the 3D virtual space 210 in the metaverse through the avatar 220. In the example of FIG. 2, the virtual space is depicted as 3D, but the metaverse environment is not limited to 3D. The metaverse environment may be expressed through a two-dimensional flat virtual space, or through a four-dimensional virtual space in which the sense of touch or smell is added.

A plurality of users can use/experience/experience the metaverse environment through their respective avatars. For example, within the 3D virtual space 210 in the metaverse, the first avatar performs physical activities such as moving, jumping, sitting, lying down, or exercising, and trading with the second avatar. Activities may be performed, and learning may be performed through images displayed in the 3D virtual space 210 .

In one embodiment, a transaction is made between a first avatar and a second avatar within the metaverse, or a transaction between the first avatar and a metaverse server (eg, a first avatar purchasing a work of art from a virtual art museum within the metaverse). case), the cryptocurrency of the blockchain platform can be used. Cryptocurrency may also be referred to as virtual currency, digital asset, digital currency, and the like. A transaction method through cryptocurrency will be described later in the description of FIGS. 3 and 4 .

In one embodiment, a user who controls the avatar 220 through a user device provides a view, such as observing the avatar 220 at a specific location in the 3D virtual space 210 in the metaverse, from the user device. can receive For example, the user may select an avatar (within a height range higher than the height of the avatar 220 in the 3D virtual space 210) from the user device. 220), or provided with the same view as observing the avatar 220 from the side (ie, within an altitude range lower than the height of the avatar 220 in the 3D virtual space 210). can receive In this case, the user device may be a device having a flat display such as a PC, a laptop computer, and a smart phone.

In another embodiment, a user who controls the avatar 220 through a user device may be provided with the same view as when the user becomes the avatar 220 and observes the 3D virtual space 210 from the user device. have. That is, when the avatar 220 stands in front of the TV at home in the 3D virtual space 210, the user can be provided with the same view as if he/she is in front of the TV in the 3D virtual space 210, and the avatar 220 When the user tilts his or her head upward, the user may be provided with the same view as looking at the ceiling of a home in the 3D virtual space 210 . In this case, the user device may be a head mounted display (HMD), and the 3D virtual space 210 may be a virtual reality (VR) 360 degree image implemented through the HMD.

In one embodiment, within the virtual space 210 linked with the real space, asset images corresponding to assets owned by users in the real space may be displayed in the virtual space 210 within the metaverse. For example, when a user in a real space checks an asset of interest through a user device, the corresponding check information may be linked to the metaverse and displayed. At this time, the user can manage the location, number, type, etc. of holding assets using the blockchain platform. A more detailed description related to this embodiment will be described later in the description of FIG. 5 .

3 is a diagram for explaining an example in which a blockchain transaction is performed.

A block chain is a collection of blocks connected one after another. Here, the block forming the chain may record/include confirmed transaction details traded for a certain period of time through the corresponding blockchain platform. In order for a block recording transaction details before confirmation to be approved, a validity judgment must be performed by network participants. An example of a validity judgment method or a consensus protocol will be described later in detail with reference to FIG. 4 .

Figure 3 shows a communication structure between participants performed within a specific blockchain platform. The first block chain transaction participation device 310 and the second block chain transaction participation device 320 may represent user devices of two users performing block chain transactions, and one device or all devices may be a server. can For example, each of the first blockchain transaction participation device 310 and the second block chain transaction participation device 320 may be any one of the server 110 or the user device 120 described above in FIG. 1 .

A blockchain platform may mean a blockchain ecosystem or a blockchain network operated based on an independent blockchain technology. There are various types of blockchain platforms, such as Bitcoin, Ethereum, Solana, and klaytn, and each blockchain platform has a blockchain consensus protocol, interface, and block size. Some of the elements may be different. The transaction method used in each blockchain platform is cryptocurrency, and the method of generating and trading cryptocurrency may vary according to the consensus protocol adopted by each blockchain platform. The consensus protocol is described in detail in FIG. to be described later.

Ethereum is a public blockchain platform created by Vitalik Buterin on July 30, 2015, and represents the name of the platform's own currency (i.e., cryptocurrency). While Bitcoin focuses on payment or transaction-related systems, that is, functions as currency, Ethereum is based on blockchain, which is a core technology. It can provide scalability so that various applications can be operated transparently. In other words, it is a platform that allows anyone to create and use analysis applications (Decentralized Applications) called dAPP as well as currency. The mainstream of Ethereum's programming language has versatility by supporting most major programming languages such as Solidity, which is a variation of JavaScript, C++, Java, Python, and Go.

NFT (Non-Fungible Token), that is, 'non-fungible token', can refer to a blockchain-based token that is unique and scarce because it is impossible to exchange and copy. Fungible cryptocurrencies such as Bitcoin mentioned above have the same value, so 1:1 exchange is possible, whereas NFTs have values and characteristics that cannot be replaced by each being given a unique recognition value. do. By applying NFT technology that puts a unique serial number on assets that can be digitized, it is possible to create (digital) assets that cannot be duplicated, that is, the only one in the world. They range from digital contents such as texts to artworks, collectibles, game items, phonemes, various products, and virtual real estate.

The plurality of nodes 330 represent a plurality of servers, a plurality of devices, and a plurality of networks involved in the consensus protocol of transactions performed on the specific blockchain platform. The ranges of the plurality of nodes 330 may be different according to the type of consensus protocol.

In FIG. 3, it is described that the plurality of nodes 330 and the first block chain transaction participation device 310 and the second block chain transaction participation device 320 are distinguished, but this is to clearly indicate the block chain transaction participation device. In some embodiments, the plurality of nodes 330 may include the first blockchain transaction participation device 310 and the second blockchain transaction participation device 320 . The plurality of nodes 330 shown in FIG. 3, the first blockchain transaction participating device 310 and the second blockchain transaction participating device 320, through the network 100 described above in FIG. Data can be transmitted and received between them.

A method of transmitting a specific cryptocurrency used within the specific blockchain platform from the first blockchain transaction participation device 310 to the second blockchain transaction participation device 320 according to an embodiment is as follows. The address of the cryptocurrency electronic wallet owned by the first user of the first blockchain transaction participation device 310, the amount of the specific cryptocurrency to be transmitted, and the cryptocurrency electronic wallet to be transmitted (i.e. , Transaction information (or ID) including the address of the cryptocurrency electronic wallet owned by the second user of the second blockchain transaction participation device 320, the first blockchain transaction participation device 310 ) to the plurality of nodes 330, the plurality of nodes 330 may approve the transaction through a predetermined consensus protocol method. If the transaction is approved, the specified amount of cryptocurrency may be transferred from the cryptocurrency electronic wallet owned by the first user to the cryptocurrency electronic wallet owned by the second user. In other words, through the plurality of nodes 330, the specific cryptocurrency by the amount is reduced in the cryptocurrency electronic wallet owned by the first user, and in the cryptocurrency electronic wallet owned by the second user. A block recording that the specific cryptocurrency has increased by the amount can be combined with an existing block chain in the block chain platform to form a new block chain.

A smart contract refers to a digital contract method in which contract conditions are coded based on blockchain technology and the contents of the contract are fulfilled when the conditions are met. The first blockchain transaction participation device 310 and the second blockchain transaction participation device 320 according to an embodiment conclude a smart contract based on the specific block chain platform as follows. same. At this time, either of the first blockchain transaction participation device 310 and the second blockchain transaction participation device 320 supports a non-fungible token (NFT) trading platform such as, for example, opensea. It may be a server that When the first blockchain transaction participation device 310 requests the plurality of nodes 330 to create a smart contract account, the plurality of nodes 330 create a smart contract account can do. At this time, the second blockchain transaction participation device 320 agreeing to the contract details of the smart contract transfers the contract details and the first user of the first block chain transaction participation device 310 to the plurality of nodes 330. When transmitting transaction information (or ID) including the cryptocurrency electronic wallet address owned by and the cryptocurrency electronic wallet address owned by the second user of the second blockchain transaction participation device 320, the smart contract By being concluded, the contents of the contract can be realized/executed. For example, the NFT owned by the first user moves from the cryptocurrency electronic wallet of the first user to the cryptocurrency electronic wallet of the second user, and the predetermined cryptocurrency owned by the second user moves to the second user's cryptocurrency electronic wallet. It is possible to move from the user's cryptocurrency electronic wallet to the first user's cryptocurrency electronic wallet.

4 is a diagram for explaining examples of a method of proving a blockchain transaction.

Consensus protocol methods in which a plurality of nodes 330 constituting a blockchain platform prove blockchain transactions include, for example, Proof of Work (PoW) 410 and Proof of Stake (Proof of Stake). PoS) 420 exists, and the types of consensus protocol methods are not limited to the above two.

In the proof-of-work method 410, a block creator (or miner, verifier, etc.) applies a nonce value and hash algorithm with random characteristics to transaction record information, It refers to a consensus protocol that creates a block and receives compensation by detecting a hash value that satisfies the difficulty condition. Block creators can receive, for example, cryptocurrency used in the blockchain platform as a reward. Blockchain platforms that use the proof-of-work scheme 410 include, for example, Bitcoin. When the consensus protocol method of a specific block chain platform is the proof-of-work method 410, since the object of proving the block chain transaction within the specific block chain platform is the block creator (or miner, verifier, etc.), the plurality of Nodes 330 may mean the block creator.

The proof-of-stake method 420 refers to a consensus protocol that differentially grants authority to create a block to each node according to the amount of each node's stake in the blockchain platform at the time of consensus. The stake of each node may be proportional to the amount of cryptocurrency each node holds. Each node can receive a reward for the transaction fee generated by the blockchain platform according to the rate at which each node contributes to block creation. Blockchain platforms using the proof-of-stake method 420 include, for example, Solana and ADA. When the consensus protocol method of a specific blockchain platform is the proof-of-stake method (420), all participants or nodes holding cryptocurrency used in the blockchain platform are subject to proof of blockchain transactions within the specific blockchain platform. Therefore, the plurality of nodes 330 may mean all participants or nodes.

5 is a flowchart illustrating the operation of an asset management system according to an embodiment.

Operations disclosed in the flowchart of FIG. 5 may be performed in conjunction with various embodiments of the present invention. In one example, the server illustrated in FIG. 5 may correspond to the server 110 illustrated in FIG. 1 , the server 601 illustrated in FIG. 6 , or the server 700 illustrated in FIG. 7 . In one example, the operations disclosed in the flowchart of FIG. 5 may correspond to some of the (server) operations disclosed in FIGS. 1 to 4 and 7 .

In step S510, the asset management system according to an embodiment, by the user's user device, to a plurality of nodes in the blockchain platform based on blockchain technology, the user's interest (interest) of the asset Location information and type information of the asset of interest may be transmitted.

In one embodiment, the asset of interest refers to an asset that the user wants to update in an asset management system, and indicates an asset that the user is observing, an asset that the user wants to collect information through the user device, and the like. can

In an embodiment, the user device may acquire location information of the asset of interest and type information of the asset of interest based on radio frequency identification (RFID).

In one example, the transceiver of the user device may include an RFID unit for performing RFID.

RFID, also called wireless recognition, is a recognition system that reads stored data such as tags, labels, and cards with embedded semiconductor chips in a non-contact manner using radio frequencies. RFID tags can be divided into active types that require power and passive types that are operated by the electromagnetic field of the reader. RFID technology is divided into low frequency and high frequency systems according to the operating frequency. Low-frequency systems below 300 MHz are representative of standard frequencies of 125 KHz and 13.56 MHz. It has features such as inexpensive tag, small amount of data storage, short read distance, and omnidirectional antenna. The high-frequency system has an operating frequency of 400 MHz or higher, 860-930 MHz, and 2450 MHz. In particular, it has a long reading distance ranging from several meters to more than tens of meters, so it is suitable for moving objects or multi-tag packages that need to be recognized very quickly, and has a directional antenna.

In another embodiment, the user device may obtain location information of the asset of interest and type information of the asset of interest based on an airtag.

In one example, the transceiver of the user device may include an air tag unit for performing an air tag.

The basic operation method of AirTag is to track the location of AirTag using an encrypted anonymous network, and in conjunction with a smartphone equipped with a U1 chip, the direction and distance of AirTag can be precisely measured based on AR in a 3D space. can be traced In addition, it is equipped with functions that can help in case of loss, such as lost mode and movement notification, and functions for protecting personal information.

Meanwhile, although the RFID and the Airtag have been proposed as a method for the user device to acquire the location information of the asset of interest and the type information of the asset of interest, these are only examples. A method of acquiring asset type information is not limited to the above example. For example, the user device may acquire location information of the company of interest and type information of the asset of interest based on image capture (photographing, video recording, etc.). Alternatively, for example, the user device may obtain location information of the asset of interest and type information of the asset of interest by using a weight sensor and image capture together. Or, for example, the user device performs Device-to-Device (D2D) communication or Internet of Things (IoT) communication with a communication module included in the asset of interest, thereby providing information on the location of the asset of interest and the asset of interest. Type information can be obtained.

In one embodiment, the location information of the asset of interest may indicate a location of the asset of interest in a virtual space within a metaverse. For example, the position of the asset of interest may be expressed based on a Cartesian coordinate system, a polar coordinate system, or a spherical coordinate system. In another embodiment, the location information of the asset of interest may indicate a location of the asset of interest in real space.
