| + | ====== Managing provenance metadata and data access rights in distributed storage based on blockchain technology and smart contracts ====== | ||
| + | |||
| + | Currently, the implementation of large scientific, engineering and business projects is associated, as a rule, with the need to store and process large amounts of data. This leads to development of new, more economical and reliable, architecture and operating principles of information systems, including storage systems. Extreme options for architectural solutions for the latter are fully centralized and [[https:// | ||
| + | |||
| + | In other words, it is necessary to provide tools to support the implementation of business processes of storage and exchange of scientific data in a distributed environment with administratively unrelated or loosely related organizations participating in joint projects or simply exchanging data on certain conditions. First of all, this requires a provenance metadata registry that is resistant to malicious changes as well as a method of ensuring consensus among participants in the business process about the content and order of transactions with data. | ||
| + | |||
| + | It should be noted that although a number of projects have been implemented in recent years to create systems for metadata storage and management, including the provenance of data, the vast majority of the implemented solutions are [[https:// | ||
| + | |||
| + | In the framework of this project we proposed a new approach to the construction of data management system and access rights in a distributed environment, | ||
| + | |||
| + | At present, a testbed has been created in SINP MSU, on which a preliminary version of the ProvHL prototype is deployed for implementation and elaboration of the principles and algorithms developed. In addition to simply maintaining the immutable ledger with provenance metadata the problem of distributed data access management including management of access rights is solved. The metadata is written to the blockchain beforehand, and data management systems refer to the blockchain and performs the transactions recorded there (metadata driven data management). Within the testbed, smart contracts is implemented to support basic operations with files (upload, download; copy to another storage) and with directories (create, delete, content listing). The deployment of a number of nontrivial endorsement policies of transactions with data by duly authorized parties within the distributed storage system was carried out. The connection to the network of remote storages (e.g., clouds) using http and ftp protocols is also simulated. Creating a production-level ProvHL system will improve the quality and reliability of the results, obtained on the basis of processing and analyzing data in distributed computer environments. | ||
