As a startup, Yonix Digital Systems Sp. z o. o. has created the Watra Ledger system, an autonomous billing platform within blockchain technology, as well as others in the energy sector. There is a group of programmers, electronic engineers, lawyers, and financiers involved in the project.
The software is designed to support energy clusters and the emerging free electricity market. The basis of the system is the Hyperledger Iroha technology - a blockchain designed for mobile applications. Developed by the Linux Foundation, the system is responsive to and supportive of global IT concerns.
We provide the platform with an open-source code under the GNU GPL 3 license, charging for any additional services.
The genesis of the idea stems from the implementation of the research project "Building the market of electric vehicles and their charging infrastructure as the basis of energy security".
As part of the tests and trials, the problem of flexible settlements and payments for electricity consumption appeared. There are many entities involved in deliveries to the market, banks, central databases and millions of customers. While searching for the optimal solution to a number of problems, the authors of the idea discovered blockchain. This technology then proved to be a good solution to billing problems across the energy sector and several other areas.
The Watra Ledger platform is available under the GNU GPL 3 free software license. The company may charge for the platform maintenance service, service, development of dedicated functions, providing system documentation, software installation and training.
The Watra Ledger platform performs the functions of an independent billing operator in the renewable energy sector: it enables the automation of settlements of energy flow between suppliers, recipients and prosumers using tokens. The system was developed, inter alia, as part of the participation of the platform's creators in the work of the KlastER consortium - an organization created by the Ministry of Climate, AGH and the National Center for Nuclear Research, whose aim is to stimulate the development of energy clusters. Many detailed solutions and know-how have been implemented in the platform thanks to cooperation with the Niedzica Hydroelectric Power Plant Group, which is the leader of the Czorsztyn Reservoir Energy Cluster.
From an economic point of view, the concept of a virtual power plant as a business and technology provider of renewable and distributed energy sources seems to be the optimal solution for clusters and the proper operation of the power grid. It is a network of scattered connections between energy producers and consumers based on a management and billing platform, an ICT network, as well as agreements and market mechanisms. From the point of view of the power grid, a virtual power plant is a separate, controllable unit. Blockchain technology offers many new functions and possibilities.
The Hyperledger Iroha technology and the Watra Ledger based on it also include typical FinTech functions. These are, among others, payments based on the built-in smart contract system, enabling the transfer of tokens between user or device accounts. The basis here is a billing token that performs a purely accounting function, dynamically reflecting the states of energy meters or other IOT sensors. Depending on the state of legal regulations, a system of trading in prepaid tokens is also planned, the value of which is convertible and corresponds to the value of legal means of payment. This feature has been tested in the system and will be optional. Hyperledger Iroha was used in a pioneering undertaking by the National Bank of Cambodia in cooperation with the Japanese company Soramitsu as the basis of the banking payment system in this country.
The blockchain platform created by the Yodiss team can be used as an important component of the smart city concept. The Watra Ledger digital platform enables the connection of various types of sensors and uses billing and event recording, which can operate autonomously over vast areas. In addition to electricity billing, the system also enables the billing of water, heat and gas consumption. It is also possible to automate the ticketing infrastructure and to control and document the segregation of household and industrial waste.
The basis of the Watra Ledger platform is the Hyperledger Iroha blockchain technology. It is a modular blockchain designed for mobile and business applications - a system dedicated to information, payment and identity management. The platform components can therefore operate on the smallest computer devices and cooperate with measuring devices and sensors, including energy meters, creating an IOT network.
Iroha is classified as a Crash Fault Tolerant. Hyperledger blockchain technology is a free software project, one of the largest in history, developed by the Linux Foundation based in San Francisco. Supporting consortium members include: IBM, Microsoft, Intel, Deutsche Bank, SAP, Airbus, Fijitsu, CISCO, Accenture, Baidu, Hitachi, JP Morgan, NEC, American Express, Deloite, Deutsche Boerse, Lenovo, and Samsung. In total, more than 200 companies and organizations have shown confidence in the project.
Built using this underlying technology, the Watra Ledger billing platform offers monitoring and billing functions for various goods and services, including electricity, water, gas, heat and tickets. The starting point for billing is the tokenization of specific goods or services. The system architecture is based on a network of nodal distributed databases on cloud servers. Watra Ledger technology can be an important element of energy clusters or a smart city.
No. Unlike the Bitcoin or Ethereum networks, approving transactions does not require the use of large computing powers, and thus does not consume large amounts of electricity. The consensus among the Byzantyne Fault Tollerant group guarantees a high level of safety and, at the same time, low energy consumption. Hyperledger Iroha, designed for mobile applications and IOT networks, especially has an advantage over older generations of blockchain networks in this respect.
Not necessarily. The activation and recording of energy flows in the blockchain network can take place by using additional ports in existing meters or by using an optical head.
No. Only the owner or the electricity seller, who has obtained the consent of the account owner, has access to the data. The data can be exported from the blockchain network to accounting programs only at the explicit instruction of the account owner.
The strength of the blockchain network is that there is not one central database, but many identical copies in different places. Also, users can install a database node on their hardware. Because blockchain databases are dispersed, it is difficult to change the registers stored in them, hence the high reliability of blockchain records.
The Watra Ledger platform is partly private and partly public. It is a private network in the sense that an account on the network can only be created with the consent of the operator or administrator. In addition, all user data is hidden and therefore not accessible to the public. It is public in the sense that the network database nodes can also be run by entities independent of the operator. This increases the security and control of the system by users. A copy can be obtained after agreeing with the operator.
Yes. Watra Ledger platform software is released under the GNU GPL 3 license.
