Description

基於區塊鏈的節點清單維護系統及其方法Node list maintenance system based on blockchain and method thereof

本發明涉及一種維護系統及其方法,特別是在認許制的區塊鏈環境下,以區塊鏈儲存節點清單,使節點根據節點清單連結所有節點,用以維護每一節點之間的連線之基於區塊鏈的節點清單維護系統及其方法。The invention relates to a maintenance system and a method thereof, in particular, in a blockchain environment of a privileged system, a blockchain storage node list is used, so that a node connects all nodes according to a node list to maintain a connection between each node. A block-based node list maintenance system and method thereof for a line.

近年來,隨著區塊鏈技術的普及與蓬勃發展,各種基於區塊鏈的應用便如雨後春筍般出現,其中,又以認許制的區塊鏈最受金融業矚目。In recent years, with the popularization and vigorous development of blockchain technology, various blockchain-based applications have sprung up. Among them, the blockchain with recognition system is the most popular in the financial industry.

一般而言,認許制的區塊鏈會先取得整個區塊鏈網路的節點之網路位址,假設有十個節點,便預先取得十個網路位址。接下來為各節點產生一組金鑰對(Key Pair)且利用公鑰產生對應的節點識別碼,以「Ethereum」為例,節點識別碼是透過公鑰、網路地址及服務的通訊埠來產生,如節點識別碼為:「enode://f3bb48a3adf47226eeea89d08915e6d84b62797b5b67e48abb41b3c05c064dcfbe1922775103d7672fa8e122fe50c82baf136666816a360c579f0ad18f61a686@52.78.19.221:30303」。因此,在十個節點的情況下,就會先產生十個節點識別碼。接著,各節點在指定的網路位址上,使用相應的私鑰執行區塊鏈程式,例如:「Ethereum」的「Geth」。各節點會將節點搜尋功能(Node Discovery)關閉,並且使用節點資料作為靜態節點清單(Static Node List)。然而,此一方式在新增節點的情況下,需要逐一更新區塊鏈網路內的各節點之靜態節點清單,當節點數目眾多時,需要耗費大量時間才能完成新增節點,因此,具有節點擴充不便的問題。In general, the occupant blockchain will first obtain the network address of the node of the entire blockchain network. Assuming ten nodes, ten network addresses are obtained in advance. Next, a set of key pairs is generated for each node and a corresponding node identifier is generated by using the public key. Taking "Ethereum" as an example, the node identifier is communicated through the public key, the network address, and the service. Generated, for example, the node identification code is: "enode://f3bb48a3adf47226eeea89d08915e6d84b62797b5b67e48abb41b3c05c064dcfbe1922775103d7672fa8e122fe50c82baf136666816a360c579f0ad18f61a686@52.78.19.221:30303". Therefore, in the case of ten nodes, ten node identification codes are generated first. Then, each node executes the blockchain program using the corresponding private key on the specified network address, for example, "Geth" of "Ethereum". Each node will turn off the node discovery function (Node Discovery) and use the node data as a static node list. However, in the case of adding a new node, it is necessary to update the static node list of each node in the blockchain network one by one. When the number of nodes is large, it takes a lot of time to complete the newly added node, and therefore, has a node. The problem of inconvenient expansion.

綜上所述,可知先前技術中長期以來一直存在節點擴充不便之問題,因此實有必要提出改進的技術手段,來解決此一問題。In summary, it can be seen that there has been a problem of inconvenient node expansion in the prior art, and it is therefore necessary to propose an improved technical means to solve this problem.

In addition, the list array refers to a memory space for storing a list of nodes read from the blockchain. In other words, the contents of the list array are changeable and can be regarded as a variable.

以下配合圖式對本發明基於區塊鏈的節點清單維護系統及其方法做進一步說明,請先參閱「第1圖」,「第1圖」為本發明基於區塊鏈的節點清單維護系統之系統方塊圖,此系統包含:節點110及管理節點120。在節點110的部分,多個節點110組成區塊鏈網路100,每一節點110具有相同內容的區塊鏈且包含:生成模組111、讀取模組112及連線模組113。其中,生成模組111用以持續根據交易生成區塊(Block),並且在此區塊通過所述節點110驗證後,將此區塊連結在區塊鏈的尾端,以及所述節點110於初始時,根據預設的創世區塊定義檔產生創世區塊(Genesis block)以作為區塊鏈的頭端,並且同時在創世區塊中產生智能合約以記錄節點清單,此智能合約包含預先設定的合約位址。在實際實施上,假設有新的節點清單產生,可透過交易方式生成包含節點清單的區塊,並且在此區塊通過驗證後,將此區塊連結至區塊鏈的尾端,往後,節點110透過合約地址讀取節點清單時,將從最後生成的包含節點清單的區塊來進行讀取。另外,在實際實施上,可利用創世區塊定義檔設定更新智能合約的權限,例如:透過在創世區塊定義檔「genesis.json」中,設定可更新節點清單的帳號,例如:「0x1a9afb711302c5f83b5902843d1c007a1a137632」(即:特許帳號)。特別要說明的是,智能合約可記錄至少一個擁有者(以如上的帳號方式記錄),當所述節點110擁有特許帳號時,即成為智能合約的擁有者,允許發送交易去變更節點清單的內容,在實際實施上,至少需要預先設定一個特許帳號在「genesis.json」中,以避免之後無法變更節點清單的內容。The following is a description of the blockchain-based node list maintenance system and the method thereof according to the following drawings. Please refer to "FIG. 1" first, and "FIG. 1" is the system of the blockchain-based node list maintenance system of the present invention. Block diagram, this system includes: node 110 and management node 120. In the portion of the node 110, the plurality of nodes 110 form a blockchain network 100. Each node 110 has a blockchain of the same content and includes a generation module 111, a reading module 112, and a connection module 113. The generating module 111 is configured to continuously generate a block according to the transaction, and after the block is verified by the node 110, the block is connected to the end of the blockchain, and the node 110 is Initially, a Genesis block is generated as a head end of the blockchain according to a preset creation block definition file, and at the same time, a smart contract is generated in the creation block to record a node list, and the smart contract includes a preset Contract address. In actual implementation, a new node list is generated, and a block containing a node list can be generated by a transaction method, and after the block is verified, the block is linked to the end of the block chain, and then When the node 110 reads the node list through the contract address, it will read from the last generated block containing the node list. In addition, in actual implementation, the authority to update the smart contract can be set by using the creation block definition file, for example, by setting the account of the list of updateable nodes in the creation block definition file "genesis.json", for example: "0x1a9afb711302c5f83b5902843d1c007a1a137632" (ie: franchise account). In particular, the smart contract can record at least one owner (recorded in the above account mode), and when the node 110 owns the license account, it becomes the owner of the smart contract, allowing the transaction to be sent to change the contents of the node list. In actual implementation, at least one privileged account number needs to be preset in "genesis.json" to avoid the possibility of changing the contents of the node list afterwards.

讀取模組112用以持續根據合約地址讀取區塊鏈中的節點清單,並且將此節點清單的內容儲存至清單陣列,所述清單陣列包含每一節點110的節點識別碼。在實際實施上,節點110在讀取節點清單之後,當節點清單的內容與所述節點110的清單陣列之內容相同時,取消將節點清單的內容儲存至清單陣列。如此一來,可以節省將節點清單的內容儲存至清單陣列所耗費的轉換及處理時間,進而增加執行效率。The reading module 112 is configured to continuously read the list of nodes in the blockchain according to the contract address and store the contents of the list of nodes to the inventory array, the list array containing the node identification code of each node 110. In practical implementation, after reading the node list, the node 110 cancels storing the content of the node list to the list array when the content of the node list is the same as the content of the list array of the node 110. In this way, the conversion and processing time spent storing the contents of the node list to the list array can be saved, thereby increasing the execution efficiency.

連線模組113用以在加入區塊鏈網路100之前,通過預設的靜態節點清單與區塊鏈網路100連結,當加入區塊鏈網路100且更新區塊鏈之後,根據清單陣列的節點識別碼連結所有節點110,並且維護每一節點110之間的連線。所述維護每一節點110之間的連線包含中斷與已被刪除的所述節點110的連線,以及建立與新增的所述節點110的連線。在實際實施上,節點110為第一個節點時,預設的靜態節點清單可為空值(Null),第一個節點之後的所述節點110,其預設的靜態節點清單可為區塊鏈網路100中的所述節點110至少其中之一,甚至亦可直接設為管理節點120的節點識別碼。The connection module 113 is used to connect to the blockchain network 100 through a preset static node list before joining the blockchain network 100. After joining the blockchain network 100 and updating the blockchain, according to the list The node identification code of the array links all nodes 110 and maintains the connection between each node 110. The maintaining the connection between each node 110 includes disconnecting the connection with the node 110 that has been deleted, and establishing a connection with the newly added node 110. In actual implementation, when the node 110 is the first node, the preset static node list may be a null value (Null), and the node 110 after the first node may have a preset static node list as a block. At least one of the nodes 110 in the chain network 100 may even be directly set as the node identification code of the management node 120.

在管理節點120的部分,所述管理節點120用以連結區塊鏈網路100且預先儲存每一節點110的網路位址及一組金鑰對,並且根據網路位址及此組金鑰對產生對應每一節點110的節點識別碼,假設產生的節點識別碼為:「enode://f3bb48a3adf47226eeea89d08915e6d84b62797b5b67e48abb41b3c05c064dcfbe1922775103d7672fa8e122fe50c82baf136666816a360c579f0ad18f61a686@52.78.19.221:30303」。在此例的節點識別碼中,使用的金鑰為「f3bb48a3adf47226eeea89d08915e6d84b62797b5b67e48abb41b3c05c064dcfbe1922775103d7672fa8e122fe50c82baf136666816a360c579f0ad18f61a686」、網路位址為「52.78.19.221」及通訊埠為「30303」。另外,管理節點120會使用特許帳號將每一節點110的節點識別碼儲存至區塊鏈以更新節點清單。如此一來,無論新增的新節點或既有的舊節點,皆可待區塊鏈更新完成後,從最新的節點清單中取得節點識別碼,並且根據節點識別碼進行新增(建立)或刪除(中斷)節點連線,無需逐一手動更新在各節點的靜態節點清單,即可自動將每一節點110之間的連線維護在最新狀態。In the portion of the management node 120, the management node 120 is configured to connect to the blockchain network 100 and pre-store the network address and a set of key pairs of each node 110, and according to the network address and the group of gold The key pair generates a node identification code corresponding to each node 110, assuming that the generated node identification code is: "enode://f3bb48a3adf47226eeea89d08915e6d84b62797b5b67e48abb41b3c05c064dcfbe1922775103d7672fa8e122fe50c82baf136666816a360c579f0ad18f61a686@52.78.19.221:30303". In the node identification code of this example, the key used is "f3bb48a3adf47226eeea89d08915e6d84b62797b5b67e48abb41b3c05c064dcfbe1922775103d7672fa8e122fe50c82baf136666816a360c579f0ad18f61a686", the network address is "52.78.19.221", and the communication port is "30303". In addition, the management node 120 stores the node identification code of each node 110 to the blockchain using the privileged account to update the node list. In this way, regardless of the newly added new node or the existing old node, after the blockchain update is completed, the node identification code is obtained from the latest node list, and the node identification code is added (established) or Deleting (interrupting) node connections eliminates the need to manually update the static node list at each node, and automatically maintains the connection between each node 110 in the latest state.

特別要說明的是,所述節點110及管理節點120皆為具有網路連線能力且透過網路相互連接的計算機裝置。舉例來說,其可為伺服器、電腦主機等等。另外,所述管理節點120可視為在區塊鏈網路100中的一個節點,其與節點110的差異僅在於管理節點120會預先儲存每一節點110的網路位址及一組金鑰對,以及能夠產生每一節點110的節點識別碼並儲存至區塊鏈以更新節點清單。In particular, the node 110 and the management node 120 are computer devices having network connection capabilities and interconnected through a network. For example, it can be a server, a computer host, or the like. In addition, the management node 120 can be regarded as a node in the blockchain network 100, which differs from the node 110 only in that the management node 120 pre-stores the network address and a set of key pairs of each node 110. And the node identification code of each node 110 can be generated and stored in the blockchain to update the node list.

And the set of key pairs generates a node identification code corresponding to each node 110, and stores the node identification code of each node 110 to the blockchain using a privileged account to update the node list (step 230); the node 110 is joining Before the blockchain network 100, it is connected to the blockchain network 100 through a preset static node list. After joining the blockchain network 100 and updating the blockchain, the node 110 continues to read the block according to the contract address. a list of nodes in the chain, and storing the contents of the list of nodes to the inventory array (step 240); the nodes concatenate all nodes according to the node identification code of the inventory array and maintain a connection between each node 110 (step 250) . Through the above steps, the node list can be stored in the blockchain through the smart contract, and before the node 110 joins the blockchain network 100, the node is connected to the blockchain network 100 using a preset static node list. After joining the blockchain network 100, the list of nodes in the blockchain is continuously read according to the contract address, and the contents of the node list are stored to the list array to link all the nodes 110 according to the node identifier of the list array, and each is maintained. A connection between a node 110.

以下配合「第3圖」及「第4圖」以實施例的方式進行如下說明,請先參閱「第3圖」,「第3圖」為應用本發明新增節點的節點清單變化之示意圖。假設節點110根據合約地址讀取區塊鏈上的節點清單,節點110會將讀取到的節點清單之內容儲存在清單陣列,其內容如陣列311所示意。在新節點加入區塊鏈網路100之前,管理節點120會根據預先儲存的新節點之網路位址、金鑰對及通訊埠產生相應的節點識別碼320,接著,管理節點120會透過特許帳號更新區塊鏈的節點清單。至於在新節點的部分,新節點在加入區塊鏈網路100之前,會通過預設的靜態節點清單與區塊鏈網路100連結以加入區塊鏈網路100,並且在加入區塊鏈網路100之後,新節點會更新自己本身的區塊鏈,當區塊鏈網路100中的所有節點110皆完成區塊鏈的更新後,節點110從區塊鏈上讀取到的節點清單之內容同樣儲存在清單陣列中,此時,其清單陣列的內容如陣列312所示意。如此一來,所有節點110即可讀取最新節點清單以儲存至自己本身的清單陣列,以便自動維護各節點110之間的連線。The following description will be made by way of example with reference to "Fig. 3" and "Fig. 4". Please refer to "3rd figure" and "3rd figure" as a schematic diagram of the change of the node list of the newly added node of the present invention. Assuming node 110 reads a list of nodes on the blockchain based on the contract address, node 110 stores the contents of the list of read nodes in a list array, the contents of which are illustrated by array 311. Before the new node joins the blockchain network 100, the management node 120 generates a corresponding node identifier 320 according to the network address, key pair and communication port of the new node stored in advance, and then the management node 120 passes the license. The list of nodes for the account update blockchain. As for the new node, the new node joins the blockchain network 100 through the preset static node list to join the blockchain network 100 before joining the blockchain network 100, and joins the blockchain. After the network 100, the new node updates its own blockchain. When all the nodes 110 in the blockchain network 100 complete the update of the blockchain, the node 110 reads the list of nodes from the blockchain. The content is also stored in the inventory array, at which point the contents of its inventory array are as illustrated by array 312. In this way, all nodes 110 can read the latest node list for storage to their own inventory array to automatically maintain the connections between the various nodes 110.

如「第4圖」所示意,「第4圖」為應用本發明刪除節點的節點清單變化之示意圖。假設管理節點120欲刪除一個節點(具有節點識別碼420),其可透過特許帳號,如:「0x1a9afb711302c5f83b5902843d1c007a1a137632」更新區塊鏈的節點清單。當區塊鏈中的各節點110更新區塊鏈並且讀取最新的節點清單後,倘若發現在區塊鏈中讀取到的節點清單與本身的清單陣列的內容(其內容如陣列411所示意)不同時,節點110會將節點清單的內容重新儲存至清單陣列,其內容如陣列412所示意。此時,即完成清單陣列的內容更新,接著,節點110會根據新的清單陣列之內容維護每一節點110之間的連線,在此例中,由於刪除了一個節點識別碼420,所以新的清單陣列之內容不會有節點識別碼420,因此,所有節點110皆會中斷與具有節點識別碼420的節點之連線。As shown in "Fig. 4", "Fig. 4" is a schematic diagram showing changes in the list of nodes for deleting nodes by applying the present invention. It is assumed that the management node 120 wants to delete a node (with the node identification code 420), which can update the node list of the blockchain through a privileged account number, such as: "0x1a9afb711302c5f83b5902843d1c007a1a137632". When each node 110 in the blockchain updates the blockchain and reads the latest node list, it finds the list of nodes read in the blockchain and the contents of its own list array (the contents of which are represented by array 411). At the same time, node 110 will re-storage the contents of the node list to the inventory array, the contents of which are illustrated by array 412. At this point, the content update of the list array is completed. Then, the node 110 maintains the connection between each node 110 according to the content of the new list array. In this example, since a node identifier 420 is deleted, the new The contents of the manifest array do not have a node identification code 420, so all nodes 110 will be disconnected from the node having the node identification code 420.

綜上所述,可知本發明與先前技術之間的差異在於透過智能合約將節點清單儲存在區塊鏈,並且在節點加入區塊鏈網路之前,使用預設的靜態節點清單與區塊鏈網路連結,當節點加入區塊鏈網路之後,持續根據合約地址讀取區塊鏈中的節點清單,並且將節點清單的內容儲存至清單陣列,以便根據清單陣列的節點識別碼連結所有節點,並且維護每一節點之間的連線,藉由此一技術手段可以解決先前技術所存在的問題,進而在認許制的區塊鏈環境下,達成提高節點的擴充便利性之技術功效。In summary, it can be seen that the difference between the present invention and the prior art is that the node list is stored in the blockchain through the smart contract, and the preset static node list and the blockchain are used before the node joins the blockchain network. The network link, after the node joins the blockchain network, continuously reads the list of nodes in the blockchain according to the contract address, and stores the contents of the node list to the list array, so as to link all the nodes according to the node identifier of the list array. And maintaining the connection between each node, by this technical means can solve the problems existing in the prior art, and in the privileged blockchain environment, the technical effect of improving the convenience of the node expansion is achieved.
