Description

非同質化代幣憑證之交易確認系統Transaction confirmation system for non-homogeneous token certificates

本發明係有關於一種交易確認系統,尤其是指一種針對非同質化代幣憑證進行交易確認之交易確認系統。The present invention relates to a transaction confirmation system, in particular to a transaction confirmation system for non-homogeneous token certificates.

由於環保意識抬頭和購物型態的轉變,消費者和企業雙方都覺得有以新的貨幣支付方式來因應新的消費型態或清算營業所得之需求,電子支付技術逐漸廣為社會大眾所應用。在電子支付中,雖然仍以實體貨幣為計價單位,並利用電子憑證進行支付行為,但是大部分的個人資料(特別是身分驗證資料)、支付運算資料、清算資料與帳戶資料,都過度集中儲存在雲端伺服器中處理,在使用者利用行動式通信裝置與雲端伺服器進行資料驗證與傳輸的過程中,相對比較容易被駭客侵入竊取個人資料或竄改交易紀錄。此外,由於目前的電子支付仍需借助金融機構或系統管理業者之系統資源,因而在完成交易後,通常會被扣取一部分之交易手續費,造成企業額外的損失。Due to rising awareness of environmental protection and changes in shopping patterns, both consumers and businesses feel that there is a need to use new currency payment methods to meet new consumption patterns or clear business income needs, and electronic payment technology is gradually widely used by the general public. In electronic payment, although physical currency is still used as the denomination unit and electronic certificates are used for payment, most of the personal data (especially identity verification data), payment calculation data, settlement data and account data are stored excessively. It is processed in the cloud server. During the process of data verification and transmission between the mobile communication device and the cloud server, it is relatively easy for hackers to steal personal data or tamper with transaction records. In addition, since the current electronic payment still needs to rely on the system resources of financial institutions or system management operators, after the transaction is completed, a part of the transaction fee is usually deducted, resulting in additional losses for the enterprise.

為了有效避免將大部份的交易資料都集中儲存在雲端伺服器,而導致容易暴露於交易紀錄被竊取或竄改的風險中,一種利用利用加密貨幣支付的新型態交易方式就孕育而生。在加密貨幣支付的交易方式中,是透過區塊鏈技術,使得過去需要透過中心集中發行和驗證的模式,可以單純依靠分散式的電腦節點達到驗證和價值傳輸的功能,所以可以去中心化地運作。In order to effectively avoid the centralized storage of most of the transaction data in the cloud server, resulting in easy exposure to the risk of transaction records being stolen or tampered with, a new type of transaction method that utilizes encrypted currency payment is born. In the transaction method of cryptocurrency payment, through the blockchain technology, the previous mode of centralized issuance and verification through the center can be achieved by relying solely on decentralized computer nodes to achieve the functions of verification and value transmission, so it can be decentralized. operate.

另一方面,在日益沉重的工作與生活壓力下,人類開始需要藉由對創意作品的欣賞與品味來紓緩壓力。在此前提下諸多創意作品,諸如畫作、藝術品、音樂、影片、美術、遊戲、口號標語、或其他限時限量專案活動等創意商品在市場上的需求也與日俱增。雖然這些創意作品本身是可以無限複製的,但這些代表它們的代幣憑證卻能在其底層的區塊鏈上被完整地溯源追蹤,藉此能為買家提供具有公信力的所有權證明,也讓擁有這些所有權證明的人們在心靈上有了更深的滿足感。於是,非同質化代幣(英語:Non-Fungible Token,簡稱:NFT)也就孕育而生。On the other hand, under the increasingly heavy pressure of work and life, human beings began to need to relieve the pressure by appreciating and tasting creative works. Under this premise, many creative works, such as paintings, artworks, music, films, art, games, slogans, or other limited-time and limited-edition projects, are in increasing demand in the market. Although these creative works themselves can be copied infinitely, the token certificates representing them can be completely traced and traced on the underlying blockchain, thereby providing buyers with credible proof of ownership and allowing People who have these proofs of ownership have a deeper sense of spiritual satisfaction. As a result, non-homogeneous tokens (English: Non-Fungible Token, referred to as: NFT) were born.

NFT是一種被稱為區塊鏈數位帳本上的資料單位,每一NFT可以代表一個獨特的數位資料,作為虛擬商品所有權的電子認證或憑證。由於NFT與加密貨幣都是在記錄於區塊鏈上,因此,在進行交易時,可以用加密貨幣為計價單位來交易NFT,或者利用另一NFT以(虛擬)物易(虛擬)物的方式來交易NFT。在實務應用上,仍以用加密貨幣為計價單位來交易NFT的方式較為常見。NFT is a data unit known as a blockchain digital ledger. Each NFT can represent a unique digital data as an electronic certification or certificate of virtual commodity ownership. Since both NFT and cryptocurrency are recorded on the blockchain, when trading, you can trade NFT with cryptocurrency as the pricing unit, or use another NFT to (virtually) barter (virtual) things Come and trade NFTs. In practical applications, it is still more common to trade NFT with cryptocurrency as the pricing unit.

在現有利用加密貨幣為計價單位來交易NFT的技術中,通常會採用以下兩種技術。第一種技術是將一使用者的私鑰直接儲存於一由一使用者所持有並可通信連結於區塊鏈之行動式電子裝置。該行動式電子裝置中安裝有一電子錢包應用程式(電子錢包App),在將私鑰進行單向推導解密成一公鑰後,可輸入公鑰執行電子錢包App而使行動式電子裝置具備一軟體電子錢包的功能。在行動式電子裝置具備一軟體電子錢包的功能時,可顯示該使用者的軟體電子錢包中所記錄擁有的各種加密貨幣與金額,同時也能從區塊鏈中搜尋NFT圖檔並加以顯示,藉以在進行NFT交易時供使用者觀看,並直接利用儲存在行動式電子裝置中的私鑰進行簽章。Among the existing technologies that use cryptocurrencies as pricing units to trade NFTs, the following two technologies are usually used. The first technique is to store a user's private key directly in a mobile electronic device owned by a user and communicatively linked to the blockchain. An electronic wallet application program (electronic wallet App) is installed in the mobile electronic device. After one-way derivation and decryption of the private key into a public key, the public key can be input to execute the electronic wallet App so that the mobile electronic device has a software electronic function of the wallet. When the mobile electronic device has the function of a software electronic wallet, it can display various cryptocurrencies and amounts recorded in the user's software electronic wallet, and can also search for NFT image files from the blockchain and display them. In order to allow users to watch when conducting NFT transactions, and directly use the private key stored in the mobile electronic device to sign.

由於私鑰是決定區塊鏈各項虛擬物品(包含加密貨幣、NFT或其他建構於區塊鏈上之虛擬物品等)存取權或交易權的唯一重要依據,一旦私鑰被盜取,則將會導致各項虛擬物品被盜用或被轉移所有權。然而,由於使用者一般使用習慣中,通常會讓行動式電子裝置經常性地通信連結於網際網路,導致私鑰經常性地暴露在被盜取風險較高的通信環境中。為了解決上述私鑰高暴險的問題,另一個現有技術也就孕育而生。Since the private key is the only important basis for determining the access or transaction rights of various virtual items in the blockchain (including cryptocurrencies, NFT or other virtual items built on the blockchain, etc.), once the private key is stolen, the It will lead to the theft or transfer of ownership of various virtual items. However, due to the general usage habits of users, mobile electronic devices are often connected to the Internet through communication, so the private key is often exposed in a communication environment with a high risk of being stolen. In order to solve the above-mentioned problem of high risk of private keys, another existing technology was born.

在另一個現有技術中,是採用將私鑰與公鑰分開儲存的方式,其中公鑰儲存於由一使用者所持有並可通信連結於區塊鏈之行動式電子裝置,私鑰則儲存一個無法通信連結於網際網路或區塊鏈等開放式通信節點的硬體電子錢包中。只有在利用私鑰進行對智能合約簽章以進行交易時,才利用短距離通信手段通信連結由行動式電子裝置,以讀取智能合約,並將完成簽章的智能合約經由行動式電子裝置上傳至區塊鏈。然而,在現有技術中,由行動式電子裝置傳送至硬體電子錢包的待交易簽章內容多半是二進位代碼(binary code),在利用硬體電子錢包中所儲存的私鑰進行簽章時,往往還必須觀看行動式電子裝置所顯示的NFT圖檔影像才能獲悉智能合約的交易標的物與對象等資訊,所以存在必須同時操作行動式電子裝置傳與硬體電子錢包才能完成簽章的問題。若在簽章時不同時操作行動式電子裝置,則只能盲目簽章,因而衍生出誤簽章的問題。In another prior art, the method of storing the private key and the public key separately is adopted, wherein the public key is stored in a mobile electronic device held by a user and can be communicatively linked to the blockchain, and the private key is stored in A hardware electronic wallet that cannot communicate with open communication nodes such as the Internet or blockchain. Only when the private key is used to sign the smart contract for transaction, the short-distance communication means is used to communicate with the mobile electronic device to read the smart contract and upload the signed smart contract through the mobile electronic device to the blockchain. However, in the prior art, most of the transactions to be signed and signed by the mobile electronic device to the hardware electronic wallet are binary codes. When using the private key stored in the hardware electronic wallet to sign , It is often necessary to watch the NFT image file displayed on the mobile electronic device to learn about the subject matter and object of the smart contract transaction, so there is a problem that the mobile electronic device must be operated at the same time to transfer to the hardware electronic wallet to complete the signature . If the mobile electronic device is not operated at the time of signing the seal, one can only sign the seal blindly, thus deriving the problem of wrong signature.

有鑒於在先前技術中,不是存在私鑰高暴露風險的問題,就是存在必須同時操作二個裝置的不便性或容易誤簽章的問題。本發明為解決先前技術中之上述種種問題所採用之技術手段係提供一種非同質化代幣憑證(Non-Fungible Token;NFT)之交易確認系統。NFT之交易確認系統係通信連結於一區塊鏈。區塊鏈係儲存有至少一NFT、至少一對應於NFT之NFT圖檔以及至少一用以規範NFT之制式智能合約。In view of the prior art, either there is a problem of high exposure risk of the private key, or there is the problem of the inconvenience of having to operate two devices at the same time or the problem of easy mis-signing. The technical means adopted by the present invention to solve the above-mentioned various problems in the prior art is to provide a non-fungible token certificate (Non-Fungible Token; NFT) transaction confirmation system. The transaction confirmation system of NFT is communicatively linked to a blockchain. The blockchain stores at least one NFT, at least one NFT image file corresponding to the NFT, and at least one standard smart contract for regulating the NFT.

NFT之交易確認系統包含一行動式電子裝置與一硬體電子錢包。行動式電子裝置係用以通信連結於區塊鏈,係安裝有一軟體電子錢包應用程式,儲存有一公鑰,並在利用公鑰執行軟體電子錢包應用程式後作為一軟體電子錢包。軟體電子錢包包含一軟體電子錢包操作介面、一智能合約處理模組與一NFT圖檔搜尋模組。The NFT transaction confirmation system includes a mobile electronic device and a hardware electronic wallet. The mobile electronic device is used to communicate with the block chain, install a software electronic wallet application program, store a public key, and use the public key to execute the software electronic wallet application program as a software electronic wallet. The software electronic wallet includes a software electronic wallet operation interface, a smart contract processing module and an NFT image file search module.

軟體電子錢包操作介面係供一使用者輸入該至少一NFT中之一者作為一待交易NFT,並供使用者輸入一交易對象之一交易對象位址。智能合約處理模組係用以依據所輸入之待交易NFT,在區塊鏈中從該至少一NFT之制式智能合約中搜尋出一用以規範待交易NFT之待用制式智能合約,更用以依據待交易NFT、交易對象位址與待用制式智能合約而產生一待簽章智能合約。NFT圖檔搜尋模組係用以利用公鑰與待交易NFT,在區塊鏈中從該至少一NFT圖檔中搜尋出一對應於待交易NFT之待交易NFT圖檔。The software electronic wallet operation interface is for a user to input one of the at least one NFT as an NFT to be traded, and for the user to input an address of a traded object. The smart contract processing module is used to search for a standard smart contract for standardizing the NFT to be traded from the at least one NFT standard smart contract in the blockchain according to the input NFT to be traded, and is further used to Generate a smart contract to be signed according to the NFT to be traded, the address of the transaction object and the standard smart contract to be used. The NFT image file search module is used to use the public key and the NFT to be traded to search for an NFT image file to be traded corresponding to the NFT to be traded from the at least one NFT image file in the blockchain.

硬體電子錢包係安裝有一硬體電子錢包應用程式,儲存有一私鑰,具有一顯示器,並用以通信連結於行動式電子裝置以擷取待交易NFT圖檔、交易對象位址與待簽章智能合約。顯示器係播放待交易NFT圖檔與顯示交易對象位址。The hardware electronic wallet is installed with a hardware electronic wallet application program, stores a private key, has a display, and is used to communicate with the mobile electronic device to retrieve the NFT image file to be traded, the address of the transaction object and the smart card to be signed contract. The monitor plays the NFT image file to be traded and displays the address of the trade object.

硬體電子錢包在執行該硬體電子錢包應用程式後產生一交易確認操作介面與一簽章產生模組。交易確認操作介面係用以在使用者確認顯示器所顯示之待交易NFT圖檔與交易對象位址無誤後,供使用者操作確認而產生一操作確認信號。簽章產生模組係用以在接收到操作確認信號後,利用私鑰對待簽章智能合約加以簽章而形成一已簽章智能合約,並用以將已簽章智能合約經由行動式電子裝置傳送至區塊鏈進行交易確認。The hardware electronic wallet generates a transaction confirmation operation interface and a signature generating module after executing the hardware electronic wallet application program. The transaction confirmation operation interface is used to generate an operation confirmation signal for the user to operate and confirm after the user confirms that the NFT image file to be traded and the address of the transaction object displayed on the display are correct. The signature generation module is used to sign the smart contract to be signed with the private key after receiving the operation confirmation signal to form a signed smart contract, and is used to transmit the signed smart contract through the mobile electronic device To the blockchain for transaction confirmation.

在上述必要技術手段的基礎下,更可延伸出以下附屬技術手段。智能合約處理模組可再包含一智能合約搜尋單元,且智能合約搜尋單元係依據待交易NFT從該至少一NFT之制式智能合約中搜尋出一用以規範待交易NFT之待用制式智能合約。智能合約處理模組可更包含一待簽章智能合約產生單元,且待簽章智能合約產生單元係用以將待交易NFT與交易對象位址寫入待用制式智能合約而將待用制式智能合約改寫成待簽章智能合約,藉以產生該待簽章智能合約。行動式電子裝置可更具有一軟體錢包儲存模組,藉以儲存公鑰以及智能合約處理模組所搜尋出之待用制式智能合約。硬體電子錢包可包含一硬體錢包儲存模組,用以儲存私鑰與該已簽章智能合約。On the basis of the above-mentioned necessary technical means, the following auxiliary technical means can be extended. The smart contract processing module may further include a smart contract search unit, and the smart contract search unit searches for a standard smart contract for standardizing the NFT to be traded from the at least one standard smart contract of the NFT according to the NFT to be traded. The smart contract processing module may further include a smart contract generation unit to be signed, and the smart contract generation unit to be signed is used to write the NFT to be traded and the address of the transaction object into the smart contract to be used, and the smart contract to be signed The contract is rewritten into a smart contract to be signed, so as to generate the smart contract to be signed. The mobile electronic device can further have a software wallet storage module to store the public key and the standby standard smart contract searched by the smart contract processing module. The hardware electronic wallet may include a hardware wallet storage module for storing the private key and the signed smart contract.

較佳者,上述行動式電子裝置可為一智慧型手機或一平板電腦,為了降低私鑰不慎外流或被盜用的風險,只有在進行交易確認時,硬體電子錢包才利用一短距離通信手段而通信連結於智慧型手機或平板電腦,且該短距離通信手段可為一藍芽通信手段或一近場無線通信(Near-field communication,NFC)手段。Preferably, the above-mentioned mobile electronic device can be a smart phone or a tablet computer. In order to reduce the risk of inadvertent leakage or theft of the private key, only when confirming the transaction, the hardware electronic wallet uses a short-distance communication The communication means is connected to the smart phone or the tablet computer, and the short-distance communication means can be a Bluetooth communication means or a near-field wireless communication (Near-field communication, NFC) means.

由以上敘述可知,在本發明所提供之NFT之交易確認系統中,係將私鑰與公鑰分別儲存在硬體電子錢包與行動式電子裝置中。整個交易確認流程大致可劃分為兩個階段進行,第一階段的主要工作是依據使用者在行動式電子裝置所輸入的待交易NFT與交易對象位址產生待用制式智能合約,並搜尋出待交易NFT圖檔;第二階段是在硬體電子錢包中顯示待交易NFT圖檔與交易對象位址,以供使用者進行操作產生已簽章智能合約供交易確認之用。It can be seen from the above description that in the NFT transaction confirmation system provided by the present invention, the private key and the public key are stored in the hardware electronic wallet and the mobile electronic device respectively. The entire transaction confirmation process can be roughly divided into two stages. The main work of the first stage is to generate a standard smart contract to be used based on the NFT to be traded and the address of the transaction object entered by the user on the mobile electronic device, and to search out the pending Transaction NFT image file; the second stage is to display the NFT image file to be traded and the address of the transaction object in the hardware electronic wallet for the user to operate to generate a signed smart contract for transaction confirmation.

由於在第一階段中,完全不會使用到私鑰,也不會讓硬體電子錢包通信連結於行動式電子裝置,只有在第二階段才會讓硬體電子錢包藉由短距離通信手段通信連結於行動式電子裝置,因此可以有效降低私鑰外流或被盜用的風險。此外,由於在第二階段使用者利用硬體電子錢包對待簽章智能合約進行簽章時,可在硬體電子錢包直接觀看到待交易NFT圖檔與交易對象位址,因此不需要在同時操作觀看行動式電子裝置的情況下,也可獲悉完整的資訊完成簽章,因而大幅提升操作的便利性並大幅降低誤簽章的風險。Because in the first stage, the private key will not be used at all, and the hardware electronic wallet will not be connected to the mobile electronic device. Only in the second stage will the hardware electronic wallet be communicated by means of short-distance communication. Linked to mobile electronic devices, it can effectively reduce the risk of private key leakage or theft. In addition, since the user uses the hardware electronic wallet to sign the smart contract to be signed in the second stage, he can directly view the NFT image file to be traded and the address of the transaction object in the hardware electronic wallet, so there is no need to operate at the same time When watching the mobile electronic device, you can also know the complete information to complete the signature, thus greatly improving the convenience of operation and greatly reducing the risk of false signature.

由於本發明所提供之非同質化代幣憑證之交易確認系統,可廣泛應用於對多種非同質化代幣憑證進行交易確認的領域,其組合實施方式更是不勝枚舉,故在此不再一一贅述,僅列舉其中較佳的一個實施例來加以具體說明。Since the transaction confirmation system for non-homogeneous token certificates provided by the present invention can be widely used in the field of transaction confirmation for various non-homogeneous token certificates, and its combination implementation methods are too numerous to enumerate, so it will not be repeated here One by one will be described in detail, and only one preferred embodiment will be listed for specific description.

A private key PRK is stored in the hardware wallet storage module 22 . The hardware electronic wallet 2 here refers especially to a portable electronic device that stores a private key but does not have the ability to connect to an open data access node such as a block chain or the Internet.

請參閱第二圖,其係顯示本發明較佳實施例經過第一階段運作後之功能方塊圖。如第二圖所示,在利用公鑰PUK執行軟體電子錢包應用程式11後具有一軟體電子錢包13。軟體電子錢包13包含一軟體電子錢包操作介面131、一智能合約處理模組132與一NFT圖檔搜尋模組133。Please refer to the second figure, which shows the functional block diagram of the preferred embodiment of the present invention after the first stage of operation. As shown in the second figure, there is a software electronic wallet 13 after executing the software electronic wallet application program 11 using the public key PUK. The software electronic wallet 13 includes a software electronic wallet operation interface 131 , a smart contract processing module 132 and an NFT image file search module 133 .

軟體電子錢包操作介面131係供使用者300在NFT N1~N3中選擇輸入其中一者作為一待交易NFT,在本實施例中使用者300選擇NFT N2作為待交易NFT。同時,軟體電子錢包操作介面131還供使用者300輸入一交易對象之一交易對象位址TA,並將交易對象位址TA儲存於軟體錢包儲存模組12。所謂的交易對象位址TA,是指在完成交易後,代表下一位擁有待交易NFT(即NFT N2)的所有權人的位址。The software electronic wallet operation interface 131 is for the user 300 to select and input one of the NFTs N1-N3 as an NFT to be traded. In this embodiment, the user 300 selects NFT N2 as the NFT to be traded. At the same time, the software electronic wallet operation interface 131 is also for the user 300 to input a transaction object address TA of a transaction object, and store the transaction object address TA in the software wallet storage module 12 . The so-called transaction object address TA refers to the address representing the next owner of the NFT to be traded (ie NFT N2) after the transaction is completed.

智能合約處理模組132包含一智能合約搜尋單元1321與一待簽章智能合約產生單元1322。智能合約搜尋單元1321係用以依據所輸入之待交易NFT(即NFT N2),在區塊鏈200中從制式智能合約SC1~SC3中搜尋出一用以規範待交易NFT之一者作為一待用制式智能合約,也就是搜尋出用以規範NFT N2之制式智能合約SC2作為待用制式智能合約。The smart contract processing module 132 includes a smart contract search unit 1321 and a smart contract generation unit 1322 to be signed. The smart contract search unit 1321 is used to search for one of the standard smart contracts SC1~SC3 in the blockchain 200 to standardize one of the NFTs to be traded as a pending NFT according to the input NFT to be traded (NFT N2). Using the standard smart contract means searching for the standard smart contract SC2 used to regulate NFT N2 as the standard smart contract to be used.

待簽章智能合約產生單元1322係用以將待交易NFT(即NFT N2)之一連結路徑與交易對象位址TA寫入待用制式智能合約(即制式智能合約SC2)而將待用制式智能合約改寫成一待簽章智能合約NSC,藉此產生出待簽章智能合約NSC,更可進一步將待簽章智能合約NSC儲存至軟體錢包儲存模組12。NFT圖檔搜尋模組133係用以利用公鑰PUK與待交易NFT(即NFT N2),在區塊鏈200中從NFT圖檔NF1~NF3中搜尋出一對應於待交易NFT(即NFT N2)之待交易NFT圖檔SNF(即NFT圖檔NF2),並將待交易NFT圖檔SNF儲存於軟體錢包儲存模組12。The smart contract to be signed generation unit 1322 is used to write one of the link paths of the NFT to be traded (ie NFT N2) and the transaction object address TA into the standby standard smart contract (ie standard smart contract SC2) and write the standby standard smart contract The contract is rewritten into a smart contract NSC to be signed, thereby generating a smart contract NSC to be signed, and the smart contract NSC to be signed can be further stored in the software wallet storage module 12 . The NFT image file search module 133 is used to use the public key PUK and the NFT to be traded (ie, NFT N2 ) to search for a corresponding NFT to be traded (ie, NFT N2 ) from the NFT image files NF1~NF3 in the blockchain 200 ), and store the NFT image file SNF to be traded in the software wallet storage module 12 .

由以上敘述可知,上述之軟體電子錢包操作介面131、智能合約處理模組132(包含智能合約搜尋單元1321與待簽章智能合約產生單元1322)與NFT圖檔搜尋模組133,都是在行動式電子裝置1執行軟體電子錢包應用程式11產生的,更具體而言,也就是行動式電子裝置1執行軟體電子錢包應用程式11中對應的相關主程式與副程式後所產生的。It can be seen from the above description that the above-mentioned software electronic wallet operation interface 131, smart contract processing module 132 (including the smart contract search unit 1321 and the smart contract generation unit 1322 to be signed) and the NFT image file search module 133 are all in action The mobile electronic device 1 executes the software electronic wallet application program 11, more specifically, it is generated after the mobile electronic device 1 executes the corresponding main program and subprogram in the software electronic wallet application program 11.

請參閱第三圖,其係顯示本發明較佳實施例經過第二階段運作後之功能方塊圖。如第三圖所示,在使用者300操作行動式電子裝置1而產生待簽章智能合約NSC並擷取待交易NFT圖檔SNF後,若使用者300欲進一步對待簽章智能合約NSC進行簽章,則可在此時進一步使硬體電子錢包2利用一短距離通信手段而通信連結於行動式電子裝置1,所述的短距離通信手段可為一藍芽通信手段或一近場無線通信(Near-field communication,NFC)手段。Please refer to the third figure, which shows the functional block diagram of the preferred embodiment of the present invention after the second stage of operation. As shown in the third figure, after the user 300 operates the mobile electronic device 1 to generate the smart contract NSC to be signed and retrieve the NFT image file SNF to be traded, if the user 300 wants to further sign the smart contract NSC to be signed Chapter, then at this time, the hardware electronic wallet 2 can be further connected to the mobile electronic device 1 by a short-distance communication means. The short-distance communication means can be a bluetooth communication means or a near-field wireless communication (Near-field communication, NFC) means.

藉由短距離通信手段,可使硬體電子錢包2自行動式電子裝置1擷取待交易NFT圖檔SNF、交易對象位址TA與待簽章智能合約NSC。硬體電子錢包2在執行硬體電子錢包應用程式21後產生一交易確認操作介面24與一簽章產生模組25。在使用者300操作交易確認操作介面24時,顯示器23可播放待交易NFT圖檔SNF並顯示交易對象位址TA。在使用者300確認顯示器23所顯示之待交易NFT圖檔SNF與交易對象位址TA無誤後,交易確認操作介面24可供使用者300進行操作確認,並在完成操作確認後產生一操作確認信號。By means of short-distance communication, the hardware electronic wallet 2 can automatically retrieve the NFT image file SNF to be traded, the address TA of the transaction object, and the smart contract NSC to be signed from the mobile electronic device 1 . The hardware electronic wallet 2 generates a transaction confirmation operation interface 24 and a signature generation module 25 after executing the hardware electronic wallet application program 21 . When the user 300 operates the transaction confirmation operation interface 24, the display 23 can play the NFT image file SNF to be traded and display the transaction target address TA. After the user 300 confirms that the NFT image file SNF to be traded and the address TA of the transaction object displayed on the display 23 are correct, the transaction confirmation operation interface 24 is available for the user 300 to perform operation confirmation, and an operation confirmation signal is generated after the operation confirmation is completed .

簽章產生模組25係用以在接收到操作確認信號後,利用存儲於硬體錢包儲存模組22之私鑰PRK對待簽章智能合約NSC加以簽章而形成一已簽章智能合約SSC。此時,簽章產生模組25可將已簽章智能合約SSC經由行動式電子裝置1傳送至區塊鏈200進行交易確認,更可將已簽章智能合約SSC儲存至硬體錢包儲存模組22。The signature generation module 25 is used to sign the smart contract NSC to be signed by using the private key PRK stored in the hardware wallet storage module 22 to form a signed smart contract SSC after receiving the operation confirmation signal. At this time, the signature generation module 25 can transmit the signed smart contract SSC to the blockchain 200 via the mobile electronic device 1 for transaction confirmation, and can also store the signed smart contract SSC to the hardware wallet storage module twenty two.

由以上敘述可知,上述之交易確認操作介面24與簽章產生模組25,都是在硬體電子錢包2執行硬體電子錢包應用程式21後產生的,更具體而言,也就是硬體電子錢包2執行硬體電子錢包應用程式21中對應的相關主程式與副程式後所產生的。As can be seen from the above description, the above-mentioned transaction confirmation operation interface 24 and signature generating module 25 are all generated after the hardware electronic wallet 2 executes the hardware electronic wallet application program 21, more specifically, the hardware electronic wallet The wallet 2 is generated after executing the corresponding main program and sub-program in the hardware electronic wallet application program 21 .

由以上敘述可知,在本發明所提供之NFT之交易確認系統中,係將私鑰PRK與公鑰PUK分別儲存在硬體電子錢包2與行動式電子裝置1中。整個交易確認流程大致可劃分為兩個階段進行,第一階段的主要工作是依據使用者300在行動式電子裝置1所輸入的待交易NFT(即上述實施例中的NFT N2)與交易對象位址TA產生待簽章智能合約NSC,並搜尋出待交易NFT圖檔SNF;第二階段是在硬體電子錢包中顯示待交易NFT圖檔SNF與交易對象位址TA,以供使用者300進行操作產生已簽章智能合約SSC供交易確認之用。It can be seen from the above description that in the NFT transaction confirmation system provided by the present invention, the private key PRK and the public key PUK are stored in the hardware electronic wallet 2 and the mobile electronic device 1 respectively. The entire transaction confirmation process can be roughly divided into two stages. The main work of the first stage is based on the NFT to be traded (that is, the NFT N2 in the above-mentioned embodiment) and the transaction object bit input by the user 300 on the mobile electronic device 1 . The address TA generates the smart contract NSC to be signed, and searches out the NFT image file SNF to be traded; the second stage is to display the NFT image file SNF to be traded and the address TA of the transaction object in the hardware electronic wallet for the user 300 to carry out The operation generates a signed smart contract SSC for transaction confirmation.

由於在第一階段中,完全不會使用到私鑰PRK,也不會讓硬體電子錢包2通信連結於行動式電子裝置1,只有在第二階段才會讓硬體電子錢包2藉由短距離通信手段通信連結於行動式電子裝置1,因此可以有效降低私鑰PRK外流或被盜用的風險。此外,由於在第二階段使用者利用硬體電子錢包2對待簽章智能合約NSC進行簽章時,可在硬體電子錢包2直接觀看到待交易NFT圖檔SNF與交易對象位址TA,因此不需要在同時操作觀看行動式電子裝置1的情況下,也可獲悉完整的資訊完成簽章,因而大幅提升操作的便利性並大幅降低誤簽章的風險。 Because in the first stage, the private key PRK will not be used at all, and the hardware electronic wallet 2 will not be communicated with the mobile electronic device 1, only in the second stage will the hardware electronic wallet 2 be connected via short The remote communication means is communicatively connected to the mobile electronic device 1, so the risk of the private key PRK being leaked or stolen can be effectively reduced. In addition, when the user uses the hardware electronic wallet 2 to sign the smart contract NSC to be signed in the second stage, he can directly view the NFT image file SNF and the address TA of the transaction object in the hardware electronic wallet 2. It is not necessary to operate and watch the mobile electronic device 1 at the same time, but also obtain the complete information and complete the signature, thereby greatly improving the convenience of operation and greatly reducing the risk of false signature.

藉由以上較佳具體實施例之詳述,係希望能更加清楚描述本發明之特徵與精神,而並非以上述所揭露的較佳具體實施例來對本發明之範疇加以限制。相反地,其目的是希望能涵蓋各種改變及具相等性的安排於本發明所欲申請之專利範圍的範疇內。 Through the above detailed description of the preferred embodiments, it is hoped that the characteristics and spirit of the present invention can be described more clearly, and the scope of the present invention is not limited by the preferred embodiments disclosed above. On the contrary, the intention is to cover various changes and equivalent arrangements within the scope of the patent application for the present invention.
