Bitcoin and the blockchain technology derived from it have introduced signature systems, consensus mechanisms, time stamps and other technologies. The mutual cooperation between the modules perfectly solves the security risks caused by decentralization. Therefore, the blockchain is not a new Internet technology, but a clever integration of a number of existing technologies, such as asymmetric key signatures, consensus mechanisms, time stamps, hash algorithms, and P2P communications. Generally, blockchain can be understood as a distributed ledger, or as a distributed computing and storage system.
现有的区块链***，通常是由区块链客户端向数据节点请求背书和调用智能合约，接收并验证数据节点返回的合约执行结果，然后将通过验证的合约执行结果提交给共识节点。在此过程中，远程网络调用次数过多，影响了区块链***整体处理延时以及每秒事务处理量(Transaction Per Second，TPS)的进一步优化。因此，发明人意识到，区块链客户端的存在增加了网络交互和***延迟，现有的区块链实现方法存在改善空间。In the existing blockchain system, the blockchain client usually requests an endorsement from the data node and calls the smart contract, receives and verifies the contract execution result returned by the data node, and then submits the verified contract execution result to the consensus node. In this process, there are too many remote network calls, which affects the overall processing delay of the blockchain system and the further optimization of Transaction Per Second (TPS).

参照图3所示，为本申请区块链实现方法第一实施例的流程示意图。该方法包括如下步骤：Referring to FIG. 3, it is a schematic flowchart of the first embodiment of the blockchain implementation method of this application. The method includes the following steps:
步骤S300，数据节点接收应用端发送的执行对应智能合约的请求。所述数据节点可以是与应用端建立连接的任一数据节点，例如所述数据节点3。所述应用端可以为任意具有数据收发功能的电子设备，用户可以在所述应用端向区块链***发送执行对应智能合约的请求，为了降低***延迟，所述应用端可以选择最近的数据节点进行连接和发送请求。所述智能合约也叫“可编程合约”，它是一段代码和数据的集合，即通过程序编码定义合约，预设执行条件，当触发执行条件时执行预设行为。其中的“智能”是执行上的智能，也就是说，当达到某个预设条件(例如通过背书)时，合约自动执行。智能合约的本质是一些执行任务的集合，当满足合约中的预设条件时，执行预先定义好的执行任务。通常，执行任务可包括操作和交易，操作和交易的执行请求可由用户发起。在本实施例中，所述请求对应的内容可以为“{"contract"："ClearBank"，"param"：{"args"：[“100”]}}”，其中，“ClearBank”表示智能合约的名称，“100”表示执行参数。在其他实施例中，所述请求还可以包括用户身份信息、智能合约编号、智能合约调用地址等，在此不再赘述。In step S300, the data node receives the request for executing the corresponding smart contract sent by the application. The data node may be any data node that establishes a connection with the application end, such as the data node 3. The application end can be any electronic device with data transceiving function. The user can send a request to execute the corresponding smart contract on the application end to the blockchain system. In order to reduce the system delay, the application end can select the nearest data node Make a connection and send a request. The smart contract is also called a "programmable contract", which is a collection of a piece of code and data, that is, a contract is defined by program coding, and execution conditions are preset, and the preset behavior is executed when the execution conditions are triggered. The "intelligence" is execution intelligence, that is, when a certain preset condition (for example, through endorsement) is reached, the contract is automatically executed. The essence of a smart contract is a collection of some execution tasks. When the preset conditions in the contract are met, the predefined execution tasks are executed. Generally, execution tasks can include operations and transactions, and execution requests for operations and transactions can be initiated by users. In this embodiment, the content corresponding to the request may be "{"contract": "ClearBank", "param": {"args": ["100"]}}", where "ClearBank" represents a smart contract The name of "100" means the execution parameter. In other embodiments, the request may also include user identity information, smart contract number, smart contract calling address, etc., which will not be repeated here.
在本实施例中，所述智能合约可以是预先设置的智能合约，也可以是根据所述请求生成的确定的智能合约，智能合约通过编写、编译和发布，可以在区块链***1中广播，可被存储在该区块链***1中的各个节点上。对于确定的智能合约，背书策略是确定的，即需要对该智能合约进行背书的节点和背书的规则是确定的。应用端通常会选择与需要对该智能合约进行背书的数据节点建立连接。具体地，所述应用端可以通过安全传输层协议(Transport Layer Security，TLS)与数据节点建立连接，为了保障通信安全，所述数据节点和所述应用端可以通过多次握手(Handshake)，通过TLS双向认证，从而建立连接。数据节点和应用端建立连接后，所述应用端通过建立的连接将执行对应智能合约的请求发送给所述数据节点，所述数据节点接收所述应用端发送的执行对应智能合约的请求。In this embodiment, the smart contract can be a preset smart contract, or a determined smart contract generated according to the request. The smart contract can be written, compiled, and published, and can be broadcast in the blockchain system 1. , Can be stored on each node in the blockchain system 1. For a certain smart contract, the endorsement strategy is determined, that is, the nodes that need to endorse the smart contract and the endorsement rules are determined. The application side usually chooses to establish a connection with the data node that needs to endorse the smart contract. Specifically, the application end may establish a connection with the data node through a Transport Layer Security (TLS). In order to ensure communication security, the data node and the application end may pass multiple handshake (Handshake) through TLS mutual authentication to establish a connection. After the data node and the application side establish a connection, the application side sends a request to execute the corresponding smart contract to the data node through the established connection, and the data node receives the request to execute the corresponding smart contract sent by the application side.
步骤S310，所述数据节点对智能合约进行背书，在所述智能合约通过背书后，根据所述请求中的执行参数执行该智能合约，并将合约执行结果以及对应的请求发送至共识节点群。In step S310, the data node endorses the smart contract. After the smart contract passes the endorsement, the smart contract is executed according to the execution parameters in the request, and the contract execution result and the corresponding request are sent to the consensus node group.
在本实施例中，假设所述智能合约的背书策略指定的背书节点为所述数据 节点，则所述数据节点可以通过数字签名的方式对所述智能合约进行背书，如果该智能合约通过背书，则所述数据节点将根据所述执行参数执行该智能合约，然后将合约执行结果以及对应的请求发送至所述共识节点群；。In this embodiment, assuming that the endorsing node specified by the endorsement policy of the smart contract is the data node, the data node can endorse the smart contract by way of digital signature. If the smart contract is endorsed, Then the data node will execute the smart contract according to the execution parameters, and then send the contract execution result and the corresponding request to the consensus node group;
步骤S320，所述共识节点群采用预先确定的共识算法对接收到的合约执行结果以及对应的请求进行共识排序，形成区块，并将形成的区块发送给所述数据节点。在本实施例中，所述共识算法可以是工作量证明(Proof of Work，PoW)算法、股权证明(Proof of Stake，PoS)算法、实用拜占庭容错算法(Practical Byzantine Fault Tolerance，PBFT)算法、委托权益(Delegated Proof of Stake，DPoS)算法、Raft算法或Ripple算法中的任意一种。In step S320, the consensus node group uses a predetermined consensus algorithm to perform consensus sorting on the received contract execution results and corresponding requests to form a block, and send the formed block to the data node. In this embodiment, the consensus algorithm may be a Proof of Work (PoW) algorithm, a Proof of Stake (PoS) algorithm, a Practical Byzantine Fault Tolerance (PBFT) algorithm, a commission Any of the Delegated Proof of Stake (DPoS) algorithm, Raft algorithm, or Ripple algorithm.
具体地，所述共识节点群在接收到所述数据节点发送的合约执行结果以及对应的请求后，可以根据所述请求执行所述智能合约，验证所述合约执行结果的有效性，给验证为有效的合约执行结果以及对应的请求加上序号，当所述序号达到预设序号阈值或经过预设时间阈值后，将所述合约执行结果和对应的请求打包形成区块，并将形成的区块发送给所述数据节点。Specifically, after the consensus node group receives the contract execution result sent by the data node and the corresponding request, it can execute the smart contract according to the request, verify the validity of the contract execution result, and verify as The effective contract execution result and the corresponding request plus the serial number. When the serial number reaches the preset serial number threshold or the preset time threshold, the contract execution result and the corresponding request are packaged to form a block, and the formed area The block is sent to the data node.
步骤S330，所述数据节点将所述区块广播至所有其他数据节点，并将所述合约执行结果返回给所述应用端。在本实施例中，所述数据节点在接收到所述共识节点群发送的区块后，可以将该区块广播至所有其他数据节点，各个数据节点将该区块存储至本地的区块链中，实现数据同步。所述数据节点还可以将所述合约执行结果返回给所述应用端，随后断开与该应用端的连接。Step S330, the data node broadcasts the block to all other data nodes, and returns the contract execution result to the application side. In this embodiment, after the data node receives the block sent by the consensus node group, the block can be broadcast to all other data nodes, and each data node stores the block in the local blockchain In, to achieve data synchronization. The data node may also return the contract execution result to the application terminal, and then disconnect the application terminal.
基于上述实施例提出区块链实现方法的第二实施例。参照图4所示，为本申请区块链实现方法第二实施例的流程示意图。在该实施例中，所述数据节点仅为所述智能合约确定的背书策略所指定的背书节点之一，所述数据节点需要将所述请求转发给所述背书策略指定的其他背书节点，即需要对该智能合约进行背书的其他数据节点，因此步骤S310将被步骤S311-S313替换。A second embodiment of the blockchain implementation method is proposed based on the above embodiment. Referring to FIG. 4, it is a schematic flowchart of the second embodiment of the blockchain implementation method of this application. In this embodiment, the data node is only one of the endorsing nodes specified by the endorsement policy determined by the smart contract, and the data node needs to forward the request to other endorsing nodes specified by the endorsement policy, that is Other data nodes that need to endorse the smart contract, so step S310 will be replaced by steps S311-S313.
步骤S311，所述数据节点将所述请求转发给所述智能合约确定的背书策略指定的其他数据节点。具体地，每个数据节点持有一组密钥对，该密钥对中的公钥被区块链***中的所有数据节点以及共识节点群所知，该密钥对中的私钥只由各数据节点本身持有。所述数据节点在向其他数据节点转发所述请求 时，先采用预先确定的哈希函数(例如SHA-256或MD5)对所述请求进行哈希计算，生成第一请求摘要，并用自己的私钥对该第一请求摘要进行加密，加密后的第一请求摘要将作为请求的数字签名和请求一起发送给其他数据节点。其他数据节点在接收到该请求后，先利用所述预先确定的哈希函数从接收的请求中计算出第二请求摘要，然后再用所述数字节点的公钥对请求附加的数字签名进行解密，如果解密得到的请求摘要与该第二请求摘要相同，那么接收到所述请求的数据节点就确认该数字签名是所述数据节点的，接收到的请求来自所述数据节点，未被篡改。数据在区块链***内部的传递通常可以采用类似的数据签名技术保障数据安全，包括数据节点与共识节点群之间的数据传递，为了叙述的方便和重点的突出，本申请并未着重强调这部分内容。可以理解的是，所述共识节点群中的各个共识节点也可以持有密钥对，所述共识节点群与数据节点间的数据传递以及共识节点群内部各共识节点间的数据传递都可以采用数据签名技术保障数据安全，在此不再赘述。Step S311, the data node forwards the request to other data nodes specified by the endorsement policy determined by the smart contract. Specifically, each data node holds a set of key pairs, the public key in the key pair is known by all data nodes in the blockchain system and the consensus node group, and the private key in the key pair is only Each data node itself holds. When the data node forwards the request to other data nodes, it first uses a predetermined hash function (such as SHA-256 or MD5) to hash the request, generates a first request digest, and uses its own private The key encrypts the first request digest, and the encrypted first request digest will be sent to other data nodes together with the request as the digital signature of the request. After receiving the request, other data nodes first use the predetermined hash function to calculate the second request digest from the received request, and then use the public key of the digital node to decrypt the digital signature attached to the request If the decrypted request digest is the same as the second request digest, the data node that receives the request confirms that the digital signature belongs to the data node, and the received request comes from the data node and has not been tampered with. Data transmission within the blockchain system can usually use similar data signature technology to ensure data security, including data transmission between data nodes and consensus node groups. For the convenience of narrative and highlight the key points, this application does not emphasize this. Part. It is understandable that each consensus node in the consensus node group can also hold a key pair, and the data transmission between the consensus node group and the data node and the data transmission between the consensus nodes within the consensus node group can be adopted Data signature technology guarantees data security, so I won’t repeat it here.
步骤S312，接收到所述请求的数据节点对所述智能合约进行背书，在所述智能合约通过背书后，根据所述执行参数执行所述智能合约。按照所述智能合约确定的背书策略，当该智能合约收集到所述背书策略指定的多个数据节点中预设数量数据节点的背书时，即认为该智能合约通过背书。在该智能合约通过背书后，对该智能合约进行背书的数据节点可以根据所述执行参数各自模拟执行该智能合约，每个数据节点将得到一个合约执行结果。Step S312: The data node that receives the request endorses the smart contract, and after the smart contract passes the endorsement, executes the smart contract according to the execution parameters. According to the endorsement strategy determined by the smart contract, when the smart contract collects endorsements from a preset number of data nodes among the multiple data nodes specified by the endorsement strategy, the smart contract is deemed to be endorsed. After the smart contract is endorsed, the data nodes that endorse the smart contract can simulate the execution of the smart contract according to the execution parameters, and each data node will get a contract execution result.
步骤S313，验证执行所述智能合约的各个数据节点得到的合约执行结果是否一致，若所述合约执行结果一致，则将该合约执行结果以及对应的请求发送至所述共识节点群，若所述合约执行结果不一致，则由接收所述应用端请求的数据节点将错误信息返回给所述应用端。可以理解的是，针对同一请求，如果各个数据节点得到的合约执行结果一致，则该执行结果和对应的请求将被发送至所述共识节点群，如果各个数据节点得到的合约执行结果不一致，则将发送错误信息给所述应用端，所述应用端可以根据接收到的错误信息重新发送请求或者放弃执行对应的智能合约。在本实施例中，可以由接收所述应用端请求的数据节点判断所述合约执行结果是否一致，并由该数据节点向所述共识节点群发送所述执行结果及对应的请求或向所述应用端返回错误信息。Step S313, verifying whether the contract execution results obtained by each data node executing the smart contract are consistent, if the contract execution results are consistent, then the contract execution results and the corresponding request are sent to the consensus node group, if the If the contract execution results are inconsistent, the data node that receives the application request will return error information to the application. It is understandable that for the same request, if the contract execution result obtained by each data node is consistent, the execution result and the corresponding request will be sent to the consensus node group.
