We suggest a novel approach to designing totally decentralized data management systems in distributed environments with administratively unrelated or loosely related user groups and in conditions of partial or complete lack of trust between them. This approach is based on the integration of blockchain technology, smart contracts and provenance metadata driven data management. Provenance metadata (PMD) contain key information that is necessary to determine the origin, authorship and quality of relevant data, their storage and usage consistency, and for interpretation and confirmation of relevant results of data processing. Architecture, operation principles and algorithms have been developed for the system, entitled ProvHL (Provenance HyperLedger), which provides fault-tolerant, safe and reliable management of provenance metadata, control of operations with data files, as well as resource access management in collaborative distributed computing systems (CDCS). CDCS refers to distributed systems formed by combining into a single pool of computer resources of various organizations (institutions) to work together in the framework of a project. The paper also suggests a new blockchain-based method for delegation of rights within distributed computing systems which is free from shortcomings inherent in other solutions. The main goal of the work is to demonstrate the capabilities of the proposed approach and the above technologies to improve the functional properties of CDCSs.

基于源元数据,智能合约和区块链技术的协作分布式环境中数据存储和处理的业务流程工程

我们建议一种新颖的方法来设计具有管理员无关或松散相关用户组的分布式环境中,以及它们之间部分或完全缺乏信任的情况下的完全分散式数据管理系统。这种方法基于区块链技术,智能合约和出处元数据驱动的数据管理的集成。来源元数据(PMD)包含关键信息,这些信息对于确定相关数据的来源,作者和质量,它们的存储和使用一致性以及对数据处理的相关结果的解释和确认是必需的。已为系统开发了名为ProvHL(来源HyperLedger)的体系结构,操作原理和算法,它提供了容错,安全可靠的来源元数据管理,控制数据文件的操作以及协作分布式计算系统(CDCS)中的资源访问管理。CDCS是指通过将各种组织(机构)的计算机资源合并到一个单一的池中而形成的分布式系统,以在项目框架中一起工作。该论文还提出了一种新的基于区块链的分布式计算系统中权利的授权方法,该方法没有其他解决方案固有的缺点。这项工作的主要目的是证明所提出的方法和上述技术的功能,以改善CDCS的功能特性。CDCS是指通过将各种组织(机构)的计算机资源合并到一个单一的池中而形成的分布式系统,以在项目框架中一起工作。该论文还提出了一种新的基于区块链的分布式计算系统中的权利授权方法,该方法没有其他解决方案固有的缺点。这项工作的主要目的是证明所提出的方法和上述技术的功能,以改善CDCS的功能特性。CDCS是指通过将各种组织(机构)的计算机资源合并到一个单一的池中而形成的分布式系统,以在项目框架中一起工作。该论文还提出了一种新的基于区块链的分布式计算系统中权利的授权方法,该方法没有其他解决方案固有的缺点。这项工作的主要目的是证明所提出的方法和上述技术的功能,以改善CDCS的功能特性。
