一般交易行為，是由買方及賣方雙方合意直接進行，並無公正第三方的參與，因而無從保障買賣雙方任一方的履約，造成買賣雙方於交易時需冒風險、擔心害怕。買方害怕賣方的交易標的有瑕疵、於運輸或交易過程減損、或是不履約交付交易標的。賣方則擔心買方收到交易標的後，卻不履約付清交易價金。特別在交易金額龐大時，買賣雙方其交易風險與可能損失亦隨之放大。因此先前已有金融機構、信託機構、建經公司、房屋仲介公司與電子商務公司等機構單位，辦理第三方交易中介（亦稱交易中介信託）、買賣價金信託、履約保證、信用狀與第三方支付等模式，透過公正第三方進行交易中介，以因應買賣雙方存在的信任問題與交易風險等。The general trading behavior is carried out directly by both the buyer and the seller. There is no fair third party's participation, so there is no guarantee of the performance of either party to the buyer or seller, causing the buyer and the seller to take risks and fear when trading. The buyer is afraid that the seller's transaction target is defective, derogated from the transportation or transaction process, or the contract is not fulfilled. The seller is concerned that the buyer will not pay the transaction price after receiving the transaction target. Especially when the transaction amount is huge, the trading risk and possible losses of the buyers and sellers will also be enlarged. Therefore, financial institutions, trust institutions, Jianjing companies, housing agencies and e-commerce companies have previously handled third-party transaction intermediaries (also known as transaction intermediary trusts), bid-and-trade trusts, performance guarantees, letters of credit and Three-party payment and other modes, through a fair third party to deal with the transaction, in order to deal with the trust issues and trading risks of buyers and sellers.
雖已存在第三方交易中介來降低交易風險，但在交易過程中，交易價金與交易標的進行交換時的金流與資訊流仍存在如偽造、竄改、冒名傳送等安全性問題，從而造成有遭受損失的可能，因此，現有的具有第三方交易中介的交易方式仍需要進一步之改良。Although there are already third-party transaction intermediaries to reduce the transaction risk, in the transaction process, the transaction flow and the transaction target exchange gold flow and information flow still have security problems such as forgery, tampering, impersonation, etc. The possibility of loss, therefore, the existing trading methods with third-party transaction intermediaries still need further improvement.

如圖4所示，本發明的該交易管理裝置12通過區塊鏈技術記錄的該虛擬貨幣的交易資訊包含有一付款方虛擬貨幣錢包地址、一收款方虛擬貨幣錢包地址、一輸入金額(淨收金額)、一輸出金額(淨付金額)、一交易手續費、一付款方數位簽章、一交易時間之時間戳記(Timestamp)以及一雜湊值(Hashing value)，並由該交易管理裝置12透過時間戳記與該雜湊值確保此交易內容未經竄改。該雜湊值係根據該付款方虛擬貨幣錢包地址、該收款方虛擬貨幣錢包地址、該輸入金額、該輸出金額、該交易手續費、該付款方數位簽章及該交易時間之時間戳記計算的。As shown in FIG. 4, the transaction information of the virtual currency recorded by the transaction management apparatus 12 of the present invention by the blockchain technology includes a payer virtual currency wallet address, a payee virtual currency wallet address, and an input amount (net). Received amount), an output amount (net payment amount), a transaction fee, a payer digital signature, a time stamp of a transaction time (Timestamp), and a hashing value, and the transaction management device 12 The time stamp and the hash value ensure that the transaction has not been tampered with. The hash value is calculated according to the payer virtual currency wallet address, the payee virtual currency wallet address, the input amount, the output amount, the transaction fee, the payer digital signature, and the time stamp of the transaction time. .
如圖5所示，本發明的該交易管理裝置12的區塊鏈技術中揭露之一區塊鏈(Blockchain)的架構，係由複數個區塊，亦即N個區塊(區塊1~區塊N)所形成。相鄰的兩區塊，例如區塊1與區塊2、區塊2與區塊3，依此類推，乃至區塊N-1與區塊N係相串鏈結(chaining)，形成所述區塊鏈。As shown in FIG. 5, the blockchain technology of the transaction management apparatus 12 of the present invention discloses a blockchain architecture, which is composed of a plurality of blocks, that is, N blocks (block 1~). Block N) is formed. Two adjacent blocks, such as block 1 and block 2, block 2 and block 3, and so on, and even block N-1 and block N are chained to form the Blockchain.
單一區塊的內容，亦即存放於該單一區塊內的內容，以區塊N為例，係包含該區塊N的前一個區塊之一區塊雜湊值(a hashing value of the previous block)，亦即該區塊N的前一區塊N-1之一區塊雜湊值、存放在該區塊N內的一筆或複數筆交易之紀錄，亦即n筆交易之紀錄(交易N1~交易Nn)、該區塊N完成建立之一時間戳記(time stamp)以及該區塊N之一區塊雜湊值。The content of a single block, that is, the content stored in the single block, taking block N as an example, is a hash value of a block containing the previous block of the block N (a hashing value of the previous block) ), that is, the hash value of one block of the previous block N-1 of the block N, the record of one or more transactions stored in the block N, that is, the record of n transactions (transaction N1~) Transaction Nn), the block N completes establishing a time stamp and a block hash value of the block N.
其中，該區塊N之該區塊雜湊值係由該區塊N的前一區塊N-1之該區塊雜湊值、所述一筆或複數筆交易N1~Nn之紀錄以及該區塊完成建立時之該時間戳記透過一安全雜湊演算法(cryptographic hash function)所產生。以該區塊N為當下做為存放交易之區塊為例，是以，定義該區塊N為一操作區塊。在本創作中，由於該操作區塊係為該區塊N，因此，該區塊N之前的所有區塊，亦即區塊1~區塊N-1係已完成建立，換言之，所述N-1個區塊的內容將無法再變更。因此，可透過驗證各該區塊相關聯的區塊之區塊雜湊值是否發生變更，即可判斷所述區塊1~區塊N-1的內容是否遭到竄改。一旦當該區塊鏈中任一該區塊的資料內容遭到竄改，可立即地、準確地察覺，藉此判斷資料是否完整，以及確保資料之資料完整性(integrity)。The hash value of the block of the block N is recorded by the block hash value of the previous block N-1 of the block N, the one or more transactions N1~Nn, and the block is completed. The timestamp at the time of creation is generated by a cryptographic hash function. Taking the block N as the block for storing the transaction as an example, the block N is defined as an operation block. In the present creation, since the operation block is the block N, all the blocks before the block N, that is, the block 1 to the block N-1 have been established, in other words, the N - The contents of 1 block will no longer be changed. Therefore, whether the content of the block 1~block N-1 is falsified can be determined by verifying whether the block hash value of each block associated with the block is changed. Once the data content of any of the blocks in the blockchain has been tampered with, it can be immediately and accurately detected to determine whether the data is complete and to ensure the integrity of the data.
該區塊N之該時間戳記係為當該區塊N存滿該等交易N1~Nn時，亦即，不再接收其他交易存入時，定義該區塊N完成建立，並且該區塊N之該時間戳記即為該區塊N完成建立時當下之日期與時間。此外，該時間戳記係透過以毫秒的時間格式進行記錄與儲存，為各式存取端進行轉換其所需的日期時間格式。透過紀錄不同區塊建立時之時間戳記資訊，搭配區塊鏈當中之前後區塊時間順序關係，亦即，建立在後的區塊其時間戳記必晚於建立在前的區塊的時間戳記，換言之，建立在後的區塊其時間戳記之毫秒數必大於建立在前的區塊的時間戳記之毫秒數。藉此，可透過判斷不同區塊間之時間戳記的先後資訊，以驗證是否發生任一區塊遭到竄改或發生偽造的狀況，以及驗證該等區塊的建立時間之合理性(rationality)。The timestamp of the block N is defined when the block N is full of the transactions N1~Nn, that is, when other transactions are no longer received, the block N is defined to be established, and the block N is completed. The time stamp is the current date and time when the block N is completed. In addition, the time stamp is used to record and store in a time format of milliseconds, and converts the various date and time formats required for the various access terminals. By recording the timestamp information when different blocks are created, and matching the time-order relationship of the previous and subsequent blocks in the blockchain, that is, the timestamp of the established block must be later than the timestamp of the block before the establishment. In other words, the number of milliseconds of the timestamp of the block that is created must be greater than the number of milliseconds of the timestamp of the block that was created. In this way, it is possible to verify whether any block has been tampered with or forged by verifying the time-series information of the time stamps between different blocks, and to verify the rationality of the settling time of the blocks.
如圖6所示，其中，所述區塊鏈及其所具有之區塊可建立與存放在一部或多部網路伺服器上，而各該伺服器以網路相連接，所述網路可為私有網路(private network)、公開網路(public network)或混合式網路(hybrid network)等。然，不以上述該等網路型態為限制本創作之實施。As shown in FIG. 6, the blockchain and the blocks it has can be established and stored on one or more network servers, and the servers are connected by a network. The road can be a private network, a public network, or a hybrid network. However, the implementation of this creation is not limited by the above-mentioned network types.
由於所有伺服器節點亦取得並儲存相同的區塊鏈資料。一旦，任一伺服器節點發生失效、無法存取的狀況，則可透過其他儲存該區塊鏈資料的伺服器節點取得相同的區塊鏈資料，以確保區塊鏈資料的高可用性(high availability)。Since all server nodes also get and store the same blockchain data. Once any server node fails or cannot be accessed, the same blockchain data can be obtained through other server nodes storing the blockchain data to ensure high availability of blockchain data. ).
