Description

Investor terminal for trading multi-asset collateralized security tokens {INVESTOR TERMINAL FOR SUPPROTING TRANSACTION OF MULTI-ASSET BACKED SECURITY TOKEN}

This disclosure relates to the development of a new type of financial investment product based on blockchain, and more specifically, security tokens that can be issued and operated on a blockchain network, especially based on multiple assets. It relates to a platform device that supports the issuance and operation of security tokens.

Since Satoshi Nakamoto introduced blockchain technology to the world through the cryptocurrency Bitcoin, interest in various forms of cryptocurrency and the blockchain technology that supports them has been growing. Blockchain technology is being examined for applicability in various fields because it enables transactions based on a decentralized distributed shared ledger method and provides high openness, reliability, transparency, and interactivity. In particular, new blockchain technologies such as Ethereum, which followed Bitcoin, support smart contracts, a digital contract function that specifies contract conditions on the blockchain and automatically executes the contract when the conditions are met. , The use of various forms of blockchain technology is being attempted in various industrial fields, especially in the financial field.

Meanwhile, the revitalization of investment is linked to the problem of securing liquidity. Liquidity refers to the degree to which funds can be converted into cash. Conventionally, high-value assets such as large-scale real estate or famous works of art were an investment area for only a small number of wealthy individuals, which were not easily accessible to the general public due to the problem of lack of liquidity. However, recently, as the use of blockchain technology in the financial field has increased, rights to various types of tangible or intangible assets, such as real estate, artwork, investment funds for unlisted companies, and various intellectual property rights, can be secured on the blockchain network. Attempts to provide digital tokenization for transactions are emerging. At this time, digital tokens issued based on tangible and intangible assets, unlike utility tokens (mainly tokens with inherent rights to use specific services provided on the blockchain network) issued through conventional ICOs, generate profits (mainly from the underlying asset itself). It is a security token (more accurately, an asset-backed security token) that has inherent legal ownership that can receive dividends, operating profits, etc.) or transfer ownership of the asset itself. There are expectations that the growth of the security token market will improve asset liquidity and thereby revitalize various forms of investment markets, and will serve as an important bridge connecting the traditional financial market and the blockchain technology field.

However, the security token market is a field that has just begun to emerge, and most of the issued security tokens are simply in the form of so-called single-asset collateral security tokens issued on a blockchain network based on a given asset such as real estate or works of art.

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Below, if it is judged that there is a risk of unnecessarily obscuring the gist of the present disclosure, detailed descriptions of already known functions and configurations will be omitted. In addition, it should be noted that the content described below only relates to one embodiment of the present disclosure and is not limited thereto.

The terms used in this disclosure are only used to describe specific embodiments and are not intended to limit the disclosure. For example, a component expressed in the singular should be understood as a concept that includes plural components unless the context clearly indicates only the singular. It should be understood that the term “and/or” as used in this disclosure encompasses any and all possible combinations of one or more of the listed items. Terms such as 'include' or 'have' used in this disclosure are only intended to designate the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in this disclosure, and the meaning of these terms is The use is not intended to exclude the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

In embodiments of the present disclosure, the term asset refers to anything that has an ownership value that can be converted into money, as a tangible or intangible thing of value that can be owned by someone or controlled to create value. For example, it is important to note that assets can include not only various types of assets, including real estate, artwork, jewelry, and various physical assets, but also intangible assets such as intellectual property rights such as patents and copyrights, stocks, and bonds.

In embodiments of the present disclosure, the term asset backed security token refers to rights associated with a given asset, such as the right to receive returns (dividends, operating income, etc.) from the given asset itself or the asset itself. It refers to converting transferable legal ownership into a digital token representation and uploading it to the blockchain network. It should be noted that, in embodiments of the present disclosure, the term asset-backed security token may also be used to collectively refer to single-asset-backed security tokens and multi-asset-backed security tokens, which will be described later.

Depending on the embodiment of the present disclosure, there may be cases where an asset-backed security token secures ownership of the underlying asset.

In embodiments of the present disclosure, a single-asset-backed security token refers to an asset-backed security token issued based on a single-asset, where the single-asset does not necessarily require that it be physically one asset. It should be noted that it may be physically a single asset, or alternatively, it may be a series of assets grouped into a single unit to serve as the basis for token issuance. In an embodiment of the present disclosure, the real asset that serves as the basis for issuing a single-asset collateral security token may be real estate or other tangible assets, or may be an intangible asset including intellectual property rights such as patent rights. In an embodiment of the present disclosure, the single-asset underlying the issuance of a single-asset collateralized security token may be a bundle of the same or different types of assets.

In an embodiment of the present disclosure, a multi-asset collateralized security token is issued by binding multiple, single-asset collateralized security tokens that have already been issued and offered for trading on the token platform and using them as the underlying assets. , refers to a new asset-backed security token. Here, binding may refer to the state or bundle of each single-asset-backed security token being bound to become the underlying asset of a new multi-asset-backed security token (thus, the multi-asset-backed security token's The transaction will not be referred to as a direct transaction of each single-asset collateral security token bound to the underlying asset, but will be referred to as a transaction of the value of the single-asset collateral security token bound to the underlying asset). For example (by way of example only), in an embodiment of the present disclosure, on a token platform, a single-asset collateralized security token A based on a specific asset called a (a unit of real estate, such as a' building), and a specific asset called b. When a single-asset-backed security token B based on a set of real estate (e.g., a bundle of apartments, which may be referred to as b) is issued, a predetermined number of security tokens A and a predetermined number of security tokens Based on B's binding, new multi-asset collateral security tokens may be issued. For example (by way of example only), in an embodiment of the present disclosure, on a token platform, there is a single-asset collateralized security token A' based on a specific asset (one or a series of patents) called a', and a specific asset called b' ( When a single-asset-backed security token B' based on another one or a series of patents has been issued, a new plurality is created based on the binding of a predetermined number of security tokens A' and a predetermined number of security tokens B'. -Asset-backed security tokens may be issued. In other words, a multi-asset-backed security token can be said to be based on a bundle of multiple types of tokens (specifically, multiple types of single-asset-backed security tokens) already issued on the platform, and It can be said to be indirectly based on multiple assets through each single-asset collateralized security token. Therefore, multi-asset-backed security tokens may be considered a type of derivative in the asset-backed security token market.

In the embodiment of the present disclosure, the issuance of an asset-backed security token means that the corresponding token is created on a blockchain network and placed in a state where it can be traded (or purchased), and the investor issues the token. If you purchase some of the tokens available, the tokens may be transferred to the investor's token wallet.

In addition, unless otherwise defined, all terms used in this disclosure, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the technical field to which this disclosure pertains. It should be noted that terms defined in commonly used dictionaries should be interpreted as having a meaning consistent with the context meaning of the related technology, and should not be interpreted in an overly restrictive or expanded manner unless clearly defined otherwise in the present disclosure. .
