Description
本發明係關於一種交易系統及方法，具體而言，本發明係指一種使用區塊鏈技術之代幣交易系統及方法，以供使用者透過區塊鏈網路進行交易。 The present invention relates to a trading system and method. Specifically, the present invention refers to a token trading system and method using blockchain technology for users to conduct transactions through the blockchain network.
早期，人們將區塊鏈(blockchain)視為一項獨立技術，特別是點對點在網路上的一個分類帳本，自每筆轉帳或交換產生起，每筆轉帳或交換都會被記錄在“區塊”上，而區塊與區塊間相連並形成鏈狀結構，且所有的紀錄被公布於網路上所有的節點，節點間通過共識機制形成共識。另一方面，每個節點所屬的成員都可根據許可權查閱相關交換或轉帳紀錄，但無法透過任何單一節點輕易控制和更改整個網路的資料(例如，記錄於“區塊”的資料)。 In the early days, people regarded blockchain as an independent technology, especially a peer-to-peer ledger on the network. Since each transfer or exchange was generated, each transfer or exchange would be recorded in the "block On the other hand, the blocks are connected and form a chain structure, and all records are published on all nodes on the network, and the nodes form a consensus through a consensus mechanism. On the other hand, the members to which each node belongs can check the relevant exchange or transfer records according to the permission, but it is not possible to easily control and change the data of the entire network (for example, the data recorded in "blocks") through any single node.
在區塊鏈的應用上，最常見於網路資訊安全、零售、消費、供應鏈管理、會員忠誠度管理等等。以網路資訊安全為例，由於區塊鏈的系統為公開，其核驗、發送等資料交流過程採用先進的加密技術。加密技術確保了資料來源的正確性及避免資料在傳輸過程中被他人攔截、竄改，因此，運用區塊鏈技術除了可解決以往對於中介人的需求之外，亦可降低駭客襲擊的潛在安全風險。而在零售相關產業方面，不論是實體或者虛擬之買賣，可將買家與賣家之間的信任基礎建立在區塊鏈技術的交換之上，其可去除中間人與其他相關費用，而買賣雙方的信任來自於區塊鏈技術及完善的智能合約(smart contract)，以保護其交易之安全性。從上述可知，區塊鏈的應用逐漸廣泛且具安全性。 In the application of blockchain, it is most commonly used in network information security, retail, consumption, supply chain management, member loyalty management, etc. Taking network information security as an example, since the blockchain system is open, its encryption and encryption are used in the process of data exchange such as verification and transmission. Encryption technology ensures the accuracy of the data source and prevents data from being intercepted and tampered by others during transmission. Therefore, the use of blockchain technology can not only solve the previous needs for intermediaries, but also reduce the potential security of hacker attacks. risk. In terms of retail-related industries, whether it is physical or virtual trading, the trust between buyers and sellers can be built on the exchange of blockchain technology, which can eliminate intermediaries and other related fees, while both buyers and sellers The trust comes from blockchain technology and a perfect smart contract to protect the security of its transactions. As can be seen from the above, the application of blockchain is gradually becoming more extensive and safe.
而目前要完成區塊鏈加密代幣交易的標準流程為(1)交易雙方建立區塊鏈電子錢包；(2)傳送方需準備一定數量之虛擬代幣(例如，乙太幣)；(3)進入虛擬代幣交易節點網頁(如，乙太坊交易節點網頁)；(4)輸入交易雙方的電子錢包位址、傳送方的錢包密鑰及交易金額；(5)區塊鏈礦工協助計算打包資料區塊；(6)傳送方扣除指定數量的虛擬代幣(例如，乙太幣)以支付礦工費；(7)顯示交易完成。上述的流程明顯複雜且繁瑣，所以使用者需要克服極大的門檻方能 使用區塊鏈之交易。 The current standard process for completing blockchain encrypted token transactions is (1) the two parties to establish a blockchain electronic wallet; (2) the sender needs to prepare a certain amount of virtual tokens (for example, ether); (3 ) Enter the virtual token transaction node webpage (eg, Ethereum transaction node webpage); (4) Enter the e-wallet address of both parties to the transaction, the wallet key of the sender, and the transaction amount; (5) Blockchain miner assists calculation Pack data blocks; (6) The sender deducts a specified amount of virtual tokens (for example, ether) to pay the miner's fee; (7) Shows the completion of the transaction. The above process is obviously complicated and cumbersome, so users need to overcome a huge threshold before they can Use blockchain transactions.
另一方面，從上述的流程可知使用者如想應用區塊鏈技術，使用者需要額外準備交易所需之電子錢包密鑰、虛擬代幣(如乙太幣)等等，而使用者在進入虛擬代幣交易節點網頁(如，乙太坊交易節點網頁)後，於輸入電子錢包密鑰的流程會有資安上的風險，再者，使用者尚需要自行準備乙太幣支付礦工費，這對平時習慣以實體代幣交易的使用者而言極具難度，因為一般使用者對於乙太幣的來源並不熟悉，所以，雖然區塊鏈的使用有其優點，但尚未發展出讓一般使用者方便使用區塊鏈交易的路徑。 On the other hand, it can be seen from the above process that if the user wants to apply blockchain technology, the user needs to additionally prepare the electronic wallet key, virtual token (such as ether) required for the transaction, etc., and the user is entering After the virtual token transaction node webpage (for example, the Ethereum transaction node webpage), there is a risk of security in the process of entering the electronic wallet key. Furthermore, users still need to prepare Ethereum to pay the miner's fee. This is extremely difficult for users who are usually used to trading in physical tokens, because the average user is not familiar with the source of ether. Therefore, although the use of blockchain has its advantages, it has not been developed for general use. It is convenient to use the path of blockchain transactions.
因此，綜上所述，為了提高使用者對於區塊鏈技術的使用率，亟需要提出並開發出一種簡易的操作平台或方法讓使用者能更輕易地使用區塊鏈並享受區塊鏈之優點。 Therefore, to sum up, in order to improve the user's utilization rate of blockchain technology, there is an urgent need to propose and develop a simple operating platform or method to allow users to more easily use the blockchain and enjoy the blockchain advantage.
本發明之目的在於提供一種使用者不需準備密鑰，亦不需要額外準備乙太幣支付手續費之使用區塊鏈技術之代幣交易系統，利用本系統可協調主要存在於用戶行動裝置之應用程式(Application,APP)和企業之間可進行更緊密且即時的串連，另一方面，使用者亦不需要進入區塊鏈網路(例如，乙太坊)交易節點網頁進行直接操作。於本系統中，使用者在交易過程只要直接以交易的加密代幣支付手續費；而本發明之系統於區塊鏈網路上建立一個加密代幣之智能合約(smart contract)用以協助驗證使用者之交易內容。本發明之智能合約在運作上能接收並執行外部給予之程式指令，而智能合約之條款編碼亦放置於區塊鏈網路之區塊，當智能合約被觸發而啟動，智能合約將按合約內容所編寫之條款執行並自動檢查所有條款之實施狀況。而上述智能合約之啟動尚需其合約擁有人共同透過輸入其密鑰認證後方能被啟動。 The purpose of the present invention is to provide a token transaction system using blockchain technology that does not require the user to prepare a key and does not need to additionally prepare an Ethernet payment fee. The system can coordinate the main presence on the user's mobile device The application (APP) and the enterprise can be connected more closely and in real time. On the other hand, the user does not need to enter the transaction node webpage of the blockchain network (for example, Ethereum) for direct operation. In this system, users only need to pay transaction fees directly with the encrypted tokens during the transaction process; and the system of the present invention establishes a smart contract of encrypted tokens on the blockchain network to help verify the use of Content of the transaction. The smart contract of the present invention can receive and execute externally given program instructions in operation, and the term code of the smart contract is also placed in the block of the blockchain network. When the smart contract is triggered and activated, the smart contract will follow the contract The written terms are executed and the implementation status of all terms is automatically checked. However, the activation of the above-mentioned smart contract requires the contract owner to authenticate by inputting its key.

For example, when the second token is a non-blockchain token, the first token is a blockchain token, and the non-blockchain token is to be exchanged for a blockchain token, the aforementioned exchange needs to be performed It can be exchanged with fixed or floating exchange value. For example, if the exchange value between blockchain tokens and non-blockchain tokens is 1:40, it means that 40 non-blockchain tokens can be exchanged.
在一實施例中，本發明之非區塊鏈代幣之取得來源為購物回饋、活動贈送、遊戲獎勵、由區塊鏈代幣交換而得。於某一實施例中，本發明之區塊鏈代幣之取得來源為ICO公開發行認購、加密貨幣交易所、由非區塊鏈代幣交換而得。從上述可知，本發明之非區塊鏈代幣及區塊鏈各有其獲取之管道，亦可透過本發明之系統相互交換。 In one embodiment, the non-blockchain tokens of the present invention are obtained from shopping rewards, event gifts, game rewards, and exchanged by blockchain tokens. In an embodiment, the blockchain tokens of the present invention are obtained from ICO public offering subscriptions, cryptocurrency exchanges, and exchanges from non-blockchain tokens. As can be seen from the above, the non-blockchain tokens and blockchains of the present invention each have their own acquisition channels, and can also be exchanged through the system of the present invention.
