Translated fromChinese技术领域technical field
本发明属于基于区块链的数据读写领域，尤其是一种基于区块链的非结构化数据操作方法和系统。The invention belongs to the field of data reading and writing based on block chain, in particular to a method and system for operating unstructured data based on block chain.
背景技术Background technique
区块链作为一种分布式储存技术，数据以区块的形式的存储在节点中，每个节点都拥有一个完整的备份，节点通过共识机制共同参与区块的产生，区块上链保证数据不可篡改。然而对于非结构数据上链，需要把数据拆解、分块，读取数据时需要重新组合数据，增加计算资源；其次，非结构数据存储成本非常高，这对节点同步增加不少的负担。Blockchain is a distributed storage technology. Data is stored in nodes in the form of blocks. Each node has a complete backup. The nodes participate in the generation of blocks through a consensus mechanism, and the blockchain guarantees data. Immutable. However, for unstructured data to be uploaded to the chain, the data needs to be disassembled and divided into blocks, and the data needs to be recombined when reading data, which increases computing resources; secondly, the storage cost of unstructured data is very high, which increases a lot of burden on node synchronization.
对于非结构化数据储存，目前有一种做法是IPFS。，IPFS通过把非结构数据区块化，将数据分发到不同节点分别存储，最后通过生成文件的哈希值来索引。但是这种存储方式受限于网络传输性能和背书节点计算性能，效率低下。For unstructured data storage, one of the current practices is IPFS. , IPFS blocks the unstructured data, distributes the data to different nodes for storage, and finally generates the hash value of the file to index. However, this storage method is limited by the network transmission performance and the computing performance of the endorsement node, and the efficiency is low.
还有一种做法是APP在云端直接储存非结构数据，同时把数据的MD5值上传到区块链中，通过区块链校验保证数据的不可篡改性。这种做法违背了数据储存的透明原则，APP在上链过程中，用户可通过恶意上传非法的MD5值，影响系统可靠性。而且在非结构化数据上链的过程割裂性大，难以保证数据的MD5校验过程与共享存储的非结构化保存对应管理，可信程度低。Another approach is that the APP directly stores unstructured data in the cloud, and at the same time uploads the MD5 value of the data to the blockchain to ensure that the data cannot be tampered with through blockchain verification. This approach violates the transparent principle of data storage. During the process of APP being on the chain, users can maliciously upload illegal MD5 values, which will affect the reliability of the system. In addition, the process of uploading unstructured data to the chain is highly fragmented, and it is difficult to ensure that the MD5 verification process of the data corresponds to the management of the unstructured storage of shared storage, and the degree of credibility is low.

具体实施方式Detailed ways
下面结合附图，对本发明做进一步说明。The present invention will be further described below with reference to the accompanying drawings.
作为示例性的，本实施方式中，利用FaaS+S3对象存储实现对区块链的非结构化数据存储，以下说明中FaaS使用AWS的lambda云函数。FaaS+S3对象储存是一种无服务架构，实现非结构数据储存的透明化和自动化，同时lambda云函数支持弹性管理，能够自动分配和扩展所需资源，有效降低开发成本和运营成本。As an example, in this implementation manner, FaaS+S3 object storage is used to implement unstructured data storage on the blockchain, and in the following description, FaaS uses the lambda cloud function of AWS. FaaS+S3 object storage is a serviceless architecture that realizes the transparency and automation of unstructured data storage. At the same time, lambda cloud functions support elastic management and can automatically allocate and expand required resources, effectively reducing development costs and operating costs.
在FaaS+S3对象存储方案中，用户可以直接操作S3服务器存储(读取)文件，通过S3服务自动触发lambda云函数向区块链发送相关信息来保证系统的可靠性，同时lambda云函数会记录每次操作的用户、内容、时间等信息，保证数据可追溯性。另外关于数据的MD5校验值也通过lambda云函数透明实现，防止用户入侵或恶意上传非法MD5值。In the FaaS+S3 object storage solution, users can directly operate the S3 server to store (read) files, and automatically trigger the lambda cloud function to send relevant information to the blockchain through the S3 service to ensure the reliability of the system, and the lambda cloud function will record The user, content, time and other information of each operation ensure data traceability. In addition, the MD5 check value of the data is also transparently implemented through the lambda cloud function, preventing users from intrusion or malicious uploading of illegal MD5 values.
为保证lambda云函数不被非法篡改，安全可靠运行lambda云函数，在每次执行lambda云函数，需要对lambda云函数进行校验，需事先把lambda云函数的函数名和MD5存入到区块链中。S3对象存储器中存储有对应表，该对应表记录有lambda函数名以及与该lambda函数名一一对应的源代码路径。云函数服务器可以从该对应表中根据函数名获取源代码的路径，再根据源代码的路径获取到该函数名对应的源代码。由于云函数服务器在获取源代码后还会校验源代码，而校验码已存放在区块链中，这一校验操作已经保证了源代码的可靠性，所以无需将源代码也存放在区块链中，而仅仅存储在S3对象存储器中即可。In order to ensure that the lambda cloud function is not illegally tampered with and run the lambda cloud function safely and reliably, the lambda cloud function needs to be verified every time the lambda cloud function is executed, and the function name and MD5 of the lambda cloud function must be stored in the blockchain in advance middle. A correspondence table is stored in the S3 object storage, and the correspondence table records a lambda function name and a source code path corresponding to the lambda function name one-to-one. The cloud function server can obtain the source code path according to the function name from the corresponding table, and then obtain the source code corresponding to the function name according to the source code path. Since the cloud function server will verify the source code after obtaining the source code, and the verification code has been stored in the blockchain, this verification operation has ensured the reliability of the source code, so there is no need to store the source code in the In the blockchain, it is only stored in the S3 object storage.
