By bundling the further development of Stereum and the software as a service offering StereumPlus in the legally independent Stereum Services FlexCo, the course has been set for further growth. In addition to IT infrastructure, RockLogic will concentrate on node operation for large institutional customers, and we are already working intensively on other business areas in the field of blockchain - a technology with a cornucopia of possibilities that offer a great future.

The Future

After several years of experience in large companies, it was time for Stefan Kobrc to combine his profound IT knowledge into his own company, and so in 2012 he founded RockLogic GmbH with like-minded people. Infrastructure maintenance - still a key pillar of RockLogic today as IT Infrastructure - as well as the creation of websites and IT project consulting were a solid business model that provided the basis for what was to come.

Foundation

Driven by the desire to develop a saleable product or service, the open source software Stereum was created, which, through its graphical user interface (GUI), opened Ethereum up to a wider group of users and thus promotes one of the essential basic principles of blockchain: decentralization. The success of Stereum was overwhelming. From 2020, this node setup client software developed into a highly popular tool in the Ethereum community, which brought RockLogic an excellent international reputation and many valuable partnerships.

Stereum as a Growth Engine

The new and exciting technology "blockchain", first made known by Bitcoin, promised to become a fascinating challenge from 2015 with the introduction of Ethereum. Stefan Kobrc began developing a Docker Composer, the forerunner of Stereum, to make Ethereum's service offering easier to use.

Blockchain

In the years from 2020 to 2024, the company grew from a small business to a medium-sized IT service provider with over 25 employees, and the next stage of development was launched: the founding of Stereum Services FlexCo, in which StereumPlus, an outstanding service model for the operation of Ethereum network nodes, was created and put into operation October 2024.

Company Description

Downloads

„Eine Blockchain ist eine kontinuierlich erweiterbare Liste von Datensätzen in einzelnen Blöcken. Neue Blöcke werden nach einem Konsensverfahren erstellt und mittels kryptographischer Verfahren an eine bestehende Kette angehängt. Jeder Block enthält dabei typischerweise einen kryptographisch sicheren Hash (Streuwert) des vorhergehenden Blocks, einen Zeitstempel und Transaktionsdaten.
Eine Blockchain ist ein Beispiel einer Distributed-Ledger-Technologie (dezentral geführte Kontobuchtechnologie) oder DLT und ähnelt in der Funktionsweise dem Journal der Buchführung. Die Blockchain wird auch als „Internet der Werte“ (Internet of Values) bezeichnet und legt die technische Basis für Kryptowährungen wie z.B. Bitcoin.“
(Quelle: wikipedia)

Definition

Ethereum ist die größte Smart Contract-Blockchain der Welt, ein dezentralisiertes, erlaubnisloses Netzwerk. Neben Überweisungen der eigenen Währung (Ether, ETH), bietet Ethereum das Ausführen von automatisierten Verträgen (Smart Contracts). Diese ermöglichen die Erstellung von sog. Decentralized Applications, zu deren Anwendungen zB. ein dezentrales Finanzwesen gehört. Alle Teilnehmer nutzen mit Ethereum eine gemeinsame Datenbasis.
Dabei gibt es 2 Hürden: Bisher brauchte man profunde IT-Kenntnisse, um sich überhaupt auszukennen, und ein gewisses Einstiegskapital, wenn man selbst einen Node betreiben wollte.

Die Blockchain Ethereum

Wir wollen mit unserer Software Stereum allen Menschen ermöglichen, an der Blockchain Ethereum teilzunehmen und deren umfangreiche Funktionalitäten zu nutzen - auch ohne tiefgehende IT-Programmierkenntnisse.
Und wir bieten jenen, die teilnehmen, aber keinen Netzwerkknoten auf eigener Hardware betreiben wollen, diesen Betrieb als Service an - unsere Serviceleistung Node Operation.

Unsere Mission…

Dabei kooperieren wir auch mit unserem größten Kunden: Lido, selbst ein großer Pool Node Operator auf Ethereum. Für Lido fügen wir Stereum eigene Funktionen hinzu und betreiben Nodes für deren Pool.

… für gemeinsamen Erfolg

Die Kombination von eigener Software und Node Operation als Dienstleistung macht RockLogic zu einem Vorreiter in Österreich - wir sind 2025, noch, die einzigen Österreicher, die das können.

Einzigartig in Österreich

Blockchain ist, gemeinsam mit KI, einer der größten Wachstumsbereiche unserer Zeit. Grundprinzip ist eine denzentralisierte, für alle Menschen zugängliche Technologie, mit der verschlüsselt Verträge abgeschlossen, Kryptowährungen ausgetauscht und noch viele andere interessante Dinge gemacht werden können - der Fantasie sind hier keine Grenzen gesetzt!

Virtualization Services

Node operation is a critical aspect of blockchain networks, as nodes are responsible for maintaining the network's integrity, validating transactions, and supporting the decentralized architecture that characterizes blockchain technology. Nodes are the backbone of any blockchain, ensuring that the network remains secure and that consensus mechanisms function effectively.

About Node Operation on Blockchains

By running validator nodes, RockLogic contributes to the network's security and decentralization. As Ethereum validators, we help to ensure that the network remains reliable and that transactions are processed efficiently, contributing to the blockchain's growth and stability.
This activity requires a deep understanding of the technology and commitment to maintaining the hardware and software infrastructure that keeps these nodes running optimally. For software, we use our proven open source tool Stereum for easy access to Ethereum. And for the hardware infrastructure we benefit from our decade-long experience of building our own data center in Austria, which is audited and is being enhanced to grow with our customers’ needs.

RockLogic’s Involvement in Node Operation

Lido is one of the most prominent decentralized staking protocols that allows users to participate in PoS networks without locking up their assets. Traditionally, staking involves locking assets for a specified period, which can limit liquidity and flexibility for participants. Lido addresses this by offering liquid staking, where users can stake their assets while still being able to use them in other DeFi applications.

Lido: A Key Component in Liquid Staking

RockLogic has played an active role in the Lido ecosystem by operating validator nodes that help facilitate the liquid staking process. As a node operator within the Lido network, RockLogic is responsible for validating transactions, securing the network, and generating staking rewards that are distributed to Lido users.

RockLogic's Partnership With Lido

From a business perspective, RockLogic's involvement in node operation and Lido liquid staking opens up new revenue streams through staking rewards. By running validator nodes, our company earns rewards for its participation in network consensus, which can be a lucrative source of income, especially as more networks adopt PoS models.
Moreover, RockLogic’s activities with Lido position us as a thought leader and innovator in the Web3 space. This involvement allows us to build relationships within the DeFi ecosystem, engage with other stakeholders in the blockchain community, and stay at the forefront of technological advancements in decentralized finance.

Business and Strategic Impact

Our VISION: Reliably functioning decentralized blockchains
Our MISSION: We are the most diversified node operator

While developing Stereum, we gained vast experience in the field of node operation for Ethereum as well. With its growing significance, we made node operation a new RockLogic business field in the beginning of 2024. We offer node operation as a service to those who want to participate in Ethereum, but do not want to operate a network node on their own hardware. Additionally, we also cooperate with other pool node operators, e.g. Lido, for whom we add special functions to Stereum and operate nodes for their pool.
These activities represent our dedication to decentralized finance (DeFi), infrastructure development, and Web3 technologies, further extending our expertise beyond traditional software development.

Node Operation

Over the course of our company’s history, the RockLogic team has worked on a diverse range of topics, including server maintenance, software development, and node operation on the Ethereum blockchain.
Some projects stand alone, while others are well interconnected. What they all have in common is that they have continuously expanded our knowledge and expertise. On these pages, we aim to illustrate this expertise.
