Description
技术领域technical field
本发明涉及数据处理技术领域，尤其涉及具有网络编码的区块链分布式存储方法及系统。The invention relates to the technical field of data processing, in particular to a block chain distributed storage method and system with network coding.
背景技术Background technique
1. 分布式存储，是将数据分散存储在多台独立的设备上。传统的网络存储系统采用集中的存储服务器存放所有数据，存储服务器成为系统性能的瓶颈，也是可靠性和安全性的焦点，不能满足大规模存储应用的需要。分布式网络存储系统采用可扩展的系统结构，利用多台存储服务器分担存储负荷，利用位置服务器定位存储信息，它不但提高了系统的可靠性、可用性和存取效率，还易于扩展。1. Distributed storage is to disperse and store data on multiple independent devices. Traditional network storage systems use centralized storage servers to store all data. Storage servers become the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. The distributed network storage system adopts a scalable system structure, uses multiple storage servers to share the storage load, and uses the location server to locate and store information. It not only improves the reliability, availability and access efficiency of the system, but also is easy to expand.
2. 传统的通信网络传递数据的方式是存储转发，即除了数据的发送节点和接收节点以外的节点只负责路由，而不对数据内容作任何的处理，中间节点扮演者转发器的角色。网络编码则是在节点上对数据进行编码处理，最后经过传输到达目的节点后，在用相应的译码方法还原出源数据。网络编码相比与传统的数据传输方式可以有效的提升网络吞吐量、均衡网络负载和提高带宽利用率。2. The traditional communication network transfers data by store-and-forward, that is, nodes other than the sending node and receiving node of the data are only responsible for routing, without any processing of the data content, and the intermediate nodes play the role of transponders. Network coding is to encode the data on the node, and finally after the transmission reaches the destination node, the corresponding decoding method is used to restore the source data. Compared with traditional data transmission methods, network coding can effectively improve network throughput, balance network load and improve bandwidth utilization.
3. 区块链是一个去中心化的分布式数据库，该数据库由一串使用密码学方法产生的数据区块有序链接而成，区块中包含有一定时间内产生的无法被篡改的数据记录信息。区块中包含数据记录、当前区块根哈希、前一区块的根哈希时间戳以及其他信息。区块链的工作流程是：首先发送节点将新的数据记录向全网广播；然后接收节点对区块进行校验，通过校验后数据记录将被纳入一个区块中；紧接着全网所有接收节点对该区块执行共识算法；最后通过共识算法的区块被正式纳入区块链中存储，全网节点表示接受该块。3. The blockchain is a decentralized distributed database. The database is composed of a series of data blocks generated by cryptography. The blocks contain data that cannot be tampered with within a certain period of time. record information. A block contains data records, the current block root hash, the root hash timestamp of the previous block, and other information. The workflow of the blockchain is: first, the sending node broadcasts the new data record to the entire network; then the receiving node verifies the block, and the data record will be included in a block after passing the verification; The receiving node executes the consensus algorithm on the block; finally, the block that passes the consensus algorithm is formally included in the blockchain for storage, and the nodes of the entire network indicate that they accept the block.
由于区块链的去中心化和公开透明特性，网络中的几乎所有节点都包含网络中的所有交易数据，这样才能保证交易数据不被篡改。但是随着区块链的发展，区块链系统中的每个节点的存储的区块会越来越大，这对每个节点的存储空间容量提出了极高的要求。Due to the decentralization and openness and transparency of the blockchain, almost all nodes in the network contain all transaction data in the network, so as to ensure that the transaction data will not be tampered with. However, with the development of the blockchain, the blocks stored by each node in the blockchain system will become larger and larger, which puts extremely high requirements on the storage space capacity of each node.

具体实施方式detailed description
本发明公开了一种具有网络编码的区块链分布式存储方法，包括如下步骤：The invention discloses a block chain distributed storage method with network coding, comprising the following steps:
接收步骤：网络各节点接收发送节点广播的原始交易数据；Receiving step: each node of the network receives the original transaction data broadcast by the sending node;
验证步骤：经过验证交易数据，获得网络节点的认可；Verification step: After verifying the transaction data, obtain the approval of network nodes;
编码步骤：利用网络编码对原始交易数据进行编码为多个数据包；Coding step: use network coding to encode the original transaction data into multiple data packets;
存储步骤：将多个数据包发送到网络中的多个网络节点纳入到区块并加入区块链中。Storage step: Send multiple data packets to multiple network nodes in the network into the block and add it to the blockchain.
在所述验证步骤中，经过验证交易数据，通过共识算法获得网络节点的认可。In the verification step, after verifying the transaction data, the approval of the network nodes is obtained through a consensus algorithm.
在所述编码步骤中，利用随机网络编码对原始交易数据进行编码为多个数据包。In the encoding step, random network encoding is used to encode the original transaction data into multiple data packets.
含有原始交易数据的区块中包括本身数据信息、前一区块的哈希值、时间戳。The block containing the original transaction data includes its own data information, the hash value of the previous block, and the timestamp.
本发明的工作原理是：将交易数据广播到网络各节点后，经过验证后将其纳入一个区块，随后经过共识算法，大部分节点认可并同意将其作为最新区块加入到区块链中。此时我们并不像之前的做法一样直接将数据块存储到区块链中，而是先利用网络编码对原始交易数据进行编码，然后在将编码后的数据分别存入各网络节点中的区块链中。对于随后产生的交易数据也做同样的处理。这样利用网络编码来代替直接的存储，可以缓解网络中节点的存储压力。每一个经过网络编码后的区块包含数据记录、原始交易数据的哈希值、时间戳以及其它的信息。The working principle of the present invention is: After broadcasting the transaction data to each node of the network, it will be included in a block after verification, and then through the consensus algorithm, most nodes will recognize and agree to add it to the blockchain as the latest block . At this time, we do not directly store the data blocks in the blockchain as in the previous practice, but first use network coding to encode the original transaction data, and then store the encoded data into the blocks of each network node. in the block chain. The same process is also done for the subsequent transaction data. In this way, network coding is used instead of direct storage, which can relieve the storage pressure of nodes in the network. Each network-encoded block contains data records, hashes of raw transaction data, timestamps, and other information.
如图1所示，以（3,2）码举例说明。假设网络中有五个节点，原始交易数据A经广播到各个节点并通过共识算法获得绝大多数的节点的认同。此时并不直接将交易数据A纳入一个区块进行存储，而是利用随机网络编码对A进行编码为c1、c2、c3，3个数据包。此时分别将他们发送到网络中的3个节点纳入到某一区块并加入区块链中。当下一个交易数据B到来时经过网络中大部分节点的认同后，用随机网络编码对它进行编码为d1、d2、d3，3个数据包。然后也分别发送到3个节点纳入进某一区块并加入到区块链中。含有A的区块中包含本身含数据信息、前一个区块的哈希值和时间戳以及其他的信息，含有B的区块中包含自身的数据、交易数据A的哈希值、时间戳以及其他信息。之后的交易也像A、B一样存储在网络中，此处不一一列出。As shown in Figure 1, take (3,2) code as an example. Assuming that there are five nodes in the network, the original transaction data A is broadcast to each node and obtained the approval of most of the nodes through the consensus algorithm. At this time, the transaction data A is not directly included in a block for storage, but the random network code is used to encode A into three data packets of c1, c2, and c3. At this time, the three nodes they sent to the network are included in a certain block and added to the blockchain. When the next transaction data B arrives, after being approved by most of the nodes in the network, it is encoded into three data packets of d1, d2, and d3 with random network coding. Then it is also sent to 3 nodes to be incorporated into a certain block and added to the blockchain. The block containing A contains its own data information, the hash value and timestamp of the previous block and other information, and the block containing B contains its own data, the hash value of transaction data A, timestamp and other information. Subsequent transactions are also stored in the network like A and B, and will not be listed here.
这样网络中的每个节点的存储量就缩小为原来的1/2，缓解了网络中各节点的存储压力。In this way, the storage capacity of each node in the network is reduced to 1/2 of the original, which relieves the storage pressure of each node in the network.
本发明在区块链进行存储之前，不同于传统的做法直接将数据存入，而是先将数据进行网络编码之后分别存入区块链网络中的节点。这样做相比于原来的直接存储节省了存储空间。The present invention is different from the traditional method of directly storing data before storing in the block chain, but first performs network coding on the data and then stores them in nodes in the block chain network respectively. This saves storage space compared to the original direct storage.
