Exonum

Exonum is a scalable blockchain platform with the open code. It is intended for creation of projects on a private blockchain and helps legal and to individuals and also it is safe to governments to realize the ideas and solutions.

Exonum is founded on the safe Rust programming language and applies the built-in Byzantine algorithm of consent which protects data needlessly "get" blocks, even in that case when nodes do not work properly or are subject to actions of malefactors.

The platform shows the high performance of operations on transaction processing and also gives the chance to take advantage of security of a blockchain of Bitcoin. In addition, the platform has such feature and function as transparency and smart contracts.

Exonum is available to everyone who wishes to construct the solutions based on blockchain technology.

Joint solution Bitfury Group and Etton Group for collection of data on the movement of waste

On June 27, 2019 the Bitfury Group company reported that it together with Etton Group developed the solution which will help to improve an ecological situation, thanks to use of technologies of the distributed register in a management system for waste. The platform will be built based on a blockchain platform open source — Bitfury Exonum.

According to the company, the project is going to start in the I quarter 2020. First of all a system will be started in Vladimir region on the landfills equipped with the electronic weight platform with the built-in means automatic photovideo fixings. It will help to collect and process information about results of weighing of the garbage trucks driving on a polygon and also to provide control of volume of waste and identify motor transport.

As of July, 2019 in Russia more than 60 million tons of household waste are annually formed, and this digit annually grows. The big problem is represented by waste disposal polygons, they are a source of greenhouse gases and constitute danger to health and life of people at violation of health regulations.

Application of blockchain technology, for storage of the register of the origins of waste, will allow to provide accuracy of the data in real time, will exclude a possibility of independent change of information of the register and export on polygons of the waste which is not meeting standards which the toxic waste polluting the environment is among.

Process of identification of an obrazovatel of waste will become transparent for regulatory authorities and the operator according to the address with waste. Financial calculations between the owner of the landfill and the operator on waste management which will be carried out on the basis of smart contracts of network will also be transferred to a blockchain. We are glad to be a part of the project which will help to improve an ecological situation in our country. told Dmitry Ufayev, CEO Bitfury Russia

The platform represents a private accounting system and information processing on transportation and waste disposal. Based on each object the computer connected to a blockchain of network (note) will be installed. Information on transactions will come from a set of notes to the decentralized network based on Exonum framework. As a masternoda of network both the State environmental control, and the operator on waste management can act, and nody-auditors can be set in perimeter of the regulator or independent public organizations on environmental protection.

The amount of the household waste imported on official polygons for July, 2019 in many cases is not fixed. It leads to incorrect determination of a rate for transportation and waste disposal. This system will allow if not to lower a rate, then to record it without increase. It will be the main result for citizens. told Klimov Efim, the CEO of Etton Group

Open data on an ecological situation and the existing problems in each region will allow inhabitants to obtain reliable data about quantity and structure of waste which are formed near the place of their accommodation. And preserving of information on the actual movement of waste will allow to avoid the unreasonable growth of utility rates.

Besides, connection of the additional hardware IoT will provide a possibility of automatic verification of garbage trucks and their contents, at entrance on a polygon on waste disposal. Transfer and data analysis from the onboard systems of motor transport throughout all way will help to reduce transport costs of waste significantly.

Start of the platform for maintaining queues on receiving housing based on Exonum

On April 11, 2019 international a blockchain company Bitfury Group reported that it together with IT companies "Time Trajectory" and IVS group started a blockchain platform for maintaining queues on receiving housing and improvement of living conditions. The solution is constructed based on a blockchain platform open source — Bitfury Exonum guaranteeing transparency of actions of each participant, simplicity of audit and a continued access to information.

2018

Integration into the PatentBot system

On October 25, 2018 the Bitfury Group company announced the cooperation with PatentBot for creation of a system on the basis of blockchain technology which will allow to mark the documents confirming copyright using digital time stamps. For solution deployment PatentBot will use the Exonum blockchain platform from Bitfury company. Read more here.

The functional designer for private blockchains

Not September, 2018 of Exonum — the functional designer for private blockchains who combines such characteristics as scalability, performance, transparency of transactions and security. All these characteristics receive special value in information security: protection and a guarantee of reliability, transparency of actions of each participant, simplicity of audit and a continued access to information is a way to real security and bringing financial and reputational risks to this minimum.

Release of Java Binding

The Exonum command of Bitfury Group company released on June 20, 2018 expansion for the framework of the same name which received the name Java Binding. It is the tool open source, available on GitHub in the corresponding repository of Exonum. This expansion will allow developer Java to create own products on the Exonum platform for private blockchains.

As explained in Bitfury, Java Binding thought as the tool for developer Java. With its help they can implement interfaces which will allow to expand Exonum with services with the built-in business logic. Java Binding also includes tool kit for software development (Software Development Kit, or SDK) which allows to integrate external Java applications in blokcheyn0platformu Exonum.

The developers creating own services on Java will be able to use opportunities of a core of a framework of Exonum written on Rust at the same time to develop customer services in the native language.

The current release of Java Binding is the alpha of a product intended for training of the developers mastering bases of development of a blockchain. Its purpose — to provide developers with "the training platform" where they would learn to create products on the Exonum platform.

The command actively works on adding of important functions to this tool to bring it to ready condition to mass public operation. We will start Java Binding 1.0 for implementation in solutions of industrial level soon — Gleb Paliyenko, the head of Exonum reported.

2017: Exonum start

In the summer of 2017 in Russia the Exonum platform designed to help private companies and government institutions was started it is safe to create the solutions and services based on a blockchain. The source code is available to Exonum on the official site of a product and Github. Developers can freely include, adapt and expand the source code Exonum according to assigned tasks.^[1]

Exonum is founded on the safe Rust programming language and applies the built-in Byzantine algorithm of consent which protects data needlessly "get" blocks, even in that case when nodes do not work properly or are subject to actions of malefactors. This function does adding in a blockchain of Exonum of incorrect data or change of history from malefactors impracticable, emphasized in Bitfury Group, the developer of the platform.

Even if at once several nodes are exposed to the attack, Exonum blockchain still answers key parameters of security and protects data, claim in the company. Besides, the platform is immediately updated with adding of each new block. And when using this consensus algorithm the blockchain of Exonum processes up to 3 thousand transactions per second (on the global distributed network) with a cleaning delay in 2.5 seconds.

"Interest in a blockchain more and more increases. We understand that simple, available tools using which business companies and government institutions will be able to do the products and services are necessary. Exonum just should become such tool. Before issuing the platform, it passed test on our project in Georgia where based on Exonum registration of the property rights is implemented. Also it was used for certification of survey results, protection of digital rights for creators of content and at the moment applied upon transition of the electronic government of Ukraine to a blockchain" — Valery Vavilov, the CEO of Bitfury Group told.

The due security level of a blockchain of Exonum is provided that the checked systems and also a binding to bitcoin are its cornerstone cryptographic.

As explained in Bitfury Group, the binding is a process of preserving of "the instant picture" of a system status in a public source that excludes need of unconditional trust to the administrator of a blockchain when preserving confidentiality of personal data. The service of a binding periodically saves the cryptographic hash reflecting Exonum blockchain status in a blockchain bitcoin. Even if malefactors get into the majority of nodes, any changes in a blockchain of Exonum will be written and are at once noticeable.
