Committed to Research

Research is key to a healthy tech ecosystem, helping to ensure that emerging technologies are being applied ethically and responsibly in game-changing ways.

As blockchain technology expands around the world, we believe it is essential to continue studying and evaluating the technology’s potential. Our white papers and fact sheets tackle some of the most pressing questions in the blockchain community.

Ring Signature-Based Voting on Blockchain

Feb 07, 2020

Amid ongoing digitalization, the use case of electronic voting has naturally arisen, with attempts beginning as early as 2000. Blockchain technology has the potential to bring trust and built-in auditing tools to such systems. This paper presents a prototype of the system for collective voting.
It is based on blockchain and linkable ring signatures to ensure the transfer of closed (secret) data without the loss of reliability and with respect for the privacy of group members.

Token Standard for Heterogeneous Assets Digitization into Commodity

Jan 31, 2020

This paper, written in partnership with the Moscow Financial University at Government, the Skolkovo Institute of Science and Technology and the National Research University Higher School of Economics, describes the transfer of exchange investment mechanisms to the cryptocurrency and tokenized assets market. We propose an architecture of a new token standard, which allows dividing different assets into a commodity. The implementation of the prototype on the Ethereum platform is provided. An example of the token application on the banking system is also presented.

Fractional Reservation Based Mempool Processing in Blockchains

Jan 31, 2020

Massive traffic events that impact all the nodes in the distributed system may cause a Denial of Service (DoS). Managing DoS attacks is even harder in peer-to-peer projects because of multiple equal in rights nodes (miners
or maintainers) that communicate across the globe to secure the network. This paper, written in partnership with the Moscow Financial University at Government, the Skolkovo Institute of Science and Technology and the National Research University Higher School of Economics, describes a private blockchain project demo built on Bitfury’s Exonum framework designed to prevent DoS attacks in public blockchains without transaction fees and for private blockchains without any tokens.

Bitcoin Mining and Electricity Price: A New Paradigm

Dec 10, 2019

In this article, Bitfury executive vice chairman George Kikvadze shares an update about the economics of bitcoin mining, showing that we are now in an era where the price of electricity outweighs the importance of the efficiency of hardware. Now available in Japanese, Korean and Chinese.

Bitfury Launches Enterprise Blockchain

Dec 05, 2019

The Bitfury Group today announced it has launched Exonum Enterprise, a full-service blockchain division building on Bitfury’s Exonum™ award-winning blockchain framework. The “Blockchain-as-a-Service” (or BaaS) offering will help companies and governments easily design and launch private blockchain projects.

Building cryptotokens based on permissioned blockchain framework

Dec 03, 2019

Blockchain technology has a lot of applications including but not limited to cryptotokens. For example, permissioned blockchains for state registries can include no money logic inside. But the creation of cryptotoken is a typical example of blockchain application and is a popular model to measure performance. In this paper, we described how to construct an account-based cryptotoken using Exonum, an open-source framework for creating blockchain applications, and by the means of performance tests shown that the proposed solution meets real-life throughput requirements for many applications. The proposed approach can be used to create cryptocurrencies in other open-source frameworks focused on permissioned blockchain applications.

Building a Private Currency Service Using Exonum

Dec 03, 2019

Zero-knowledge proofs are an emerging cryptographic technology that have many potential applications for blockchains. Exonum is an extensible open-source framework for creating blockchain applications. In this article, we describe how zero-knowledge proofs, specifically bulletproofs, can be applied to build a privacy-focused service using Exonum. The token logic is implemented as a platform service and is a proof of concept.

Blockchain-Based Solution to Prevent Postage Stamps Fraud

Jul 16, 2019

This research paper, published by IEEE, is a continuation of the research Bitfury published in December 2018. In this article, the researchers discuss the issue of postage stamp fraud and include a technical description and performance tests of the proposed blockchain solution.

Multi-Database Monitoring Tool for the E-Health Services

Jun 26, 2019

The paper outlines some aspects of developing an information system for e-Health database administrators (DBA). This system is equipped with advanced database performance monitoring and prediction features and based on different captured metrics as CPUs, RAMs, HDDs, and other values as well as historical events from host cluster/nodes. The data are aggregated, processed and transformed to provide the developers, production and host DBA teams with timely, proper, and valuable information about existing issues. The graphical representation of critical parameters to the working instance is provided. The approaches to forecasting database performance troubles related to the degradation of its characteristics due to different cumulative effects are discussed.
