About us

DLT Austria is an independent think-tank and sees itself as a platform for the exchange of ideas on Blockchain-Technology. DLT Austria will contribute significantly to evolve Austria into a leading country for Distributed-Ledger-Technologies. Through targeted networking, coordination and promotion of players from science, business, education and society, we want to contribute to the targeted and sustainable application of DLT in Austria.

  • We are accomplishing awareness for the benefit, the opportunities but also for the consequences of Blockchain-Technology (Transformation process)
  • We are the main driver for Blockchain initiatives
  • We are a platform for knowledge, exchange and communication
  • We are the the place to go for questions, problems or ideas related to DLT

New technologies imply big challenges and create a lot of uncertainty!

To be able to ask the proper questions and reach your goals, it is necessary to understand the fundamental technology, their functionality and use cases.

DLT Austria is bridging this gap and serves as a Think Tank and platform to facilitate an exchange for all related topics regarding Distributed-Ledger-Technologies.

A well-directed network, the coordination and the support of science, economy, education and community stakeholders enables us to facilitate a sustainable use of Blockchain-Technology in Austria.

Accomplish more together!

Our role is to be the link between stakeholders and policymakers.

Information, awareness & education

The goal is to build up basic knowledge for everyone interested in Distributed-Ledger-Technologies. The focus is set on the Blockchain-Technology and its use cases in business and industry areas like automotive, finance, insurance, public administration, real estate, transport, ICT, energy and many more.

Community-Building & Networking

We set up, we organise and we maintain all relations to strengthen the network. Our initial focus is set on Germany, Austrian and Switzerland.

Use Case & Design Thinking

Many decision makers have the difficult task to find or identify a proper use case. The correct approach to this problem is crucial. We help to develop ideas for potential use cases free of limitations and offer therefore Innovation Workshops, Design Thinking and Hackathons.

Pilot-Project assistance

The pilot project should analyse and question the Startups or enterprises in their and related industries. As a follow up it is necessary to evaluate if these ideas are putting the own business at risk and to find the optimal approach. We connect, we cooperate or we work together on innovative solutions.


We place ourselves as a link between the „DLT-/Blockchain-/Crypto- and Digital-Assets-Community“. Through well structured information and communication we are able to meet your requirements and find the best fit for everyone.

Frequently Asked Questions

The most frequently asked questions Around Distributed Ledger Technologies and Blockchain Technologies.

  • In the simplest sense, a blockchain can be described as a data structure that contains transaction records while ensuring security, transparency, and decentralization. You can also think of it as a chain of records, which are stored in the form of blocks that are basically not controlled by any single entity.

    A blockchain is a distributed ledger that is completely open to everyone on the network. Once information is stored in a blockchain, it is extremely difficult to change or delete it. Each transaction is secured with a digital signature that confirms its authenticity. Due to the use of encryption and digital signatures, the stored data is tamper-proof and cannot be changed.

    Blockchain technology allows all network participants to reach an agreement, commonly referred to as consensus. All stored data is recorded digitally and has a common history that is available to all network participants. This eliminates the risk of fraudulent activity or duplicate transactions ("double spending") without the need for a third party.

  • A blockchain is a chain of blocks. These blocks can contain any type of data or information. A new block consists of the hash of the previous block and the new data. Together these form the hash for the next block.

    The Hash

    Ein Hash ist ein eindeutiger mathematischer Code, der zu einem bestimmten Block gehört. Wenn die Informationen im Block geändert werden, dann ändert sich auch der Hash des Blocks. Die Verbindung von Blöcken über eindeutige Hash-Schlüssel macht Blockchain Manipulations- und Fälschungssicher. A hash is a unique mathematical code that belongs to a specific block. If the information in the block is changed, the hash of the block also changes. The connection of blocks via unique hash keys makes blockchain tamper-proof and forgery-proof.

    Transaction validation

    Each transaction must be validated by a node on the network. In the Bitcoin blockchain, these nodes are called "miners" and use the concept of proof-of-work to process and validate transactions in the network. For a transaction to be valid, each block must refer to the hash of the previous block. The transaction only takes place if the hash is correct.

    This ensures that the blockchain is immutable. Every change that is made to the block chain is reflected in the entire network, easily recognized and thus classified as invalid.

  • Decentralized

    The basic idea is that each blockchain is managed in a decentralized manner. This means that no single person or group has control over the entire network. While everyone in the network has a copy of the distributed ledger, nobody can change it themselves. This unique function of the blockchain enables transparency and security.

    Peer to Peer Transaction

    The blockchain makes it possible for two parties to interact securely without them knowing each other and makes a third party, which normally serves as a guarantee of trust, obsolete. Since the entire network keeps an identical copy of the transactions and is also validated by the network, the question of trust does not arise for the second party, because this is checked by the network and ensures that everything is compliant with the rules.

    Immutable and tamper-proof

    The immutability property of a blockchain refers to the fact that data once written to the blockchain cannot be changed. If you try to change the data of a block, the entire subsequent blockchain has to be changed, as each block stores the hash of the previous block. A change in one hash results in a change in all subsequent hashes. It is extremely complicated and computationally expensive to change all hashes and would also require the consensus of the entire network. Therefore, the data stored in a blockchain are not susceptible to changes or hacker attacks due to their immutability and can therefore also be viewed as tamper-proof.

  • Although the blockchain has developed on many levels since its inception, there are two main categories in which it can mainly be classified:

      * Public blockchain

      * Private Blockchain

    Both a public and a private blockchain have decentralized peer-to-peer networks. All participants in the network keep a copy of the shared ledger with them and verify each new transaction by consensus.

    Public blockchain - This is a so-called "permissionless" blockchain, anyone who has access to the Internet can download and access it and become a node in the blockchain. Therefore, the control is incumbent on the general public. An example of a public blockchain is the Bitcoin blockchain.

    Private Blockchain - In contrast to the public blockchain, the “permissioned” blockchain requires a permit or invitation to participate. Overall control of the network is in the hands of the owners. Private blockchains can be run independently of one another or integrated into other blockchains. These are typically used by businesses and organizations. Therefore, the level of trust required by the participants in private blockchains is higher.

  • The cryptocurrency

    The first application was that of the cryptocurrency. The security that everyone only spends the amount they own and that they can be trusted without knowing them, makes the whole thing so revolutionary.

    Smart Contracts

    Smart contracts perform similar functions to paper-based agreements. The distinguishing feature of intelligent contracts is that they can be executed both digitally and personally. Self-executable means that if certain pre-determined conditions are met, these contracts are then automatically considered to be fulfilled and trigger an action.

    Intellectual property protection

    Digital content or information can be easily reproduced and distributed using the Internet. Because of this, people from all over the world have the opportunity to copy, replicate, and use them without giving credits to the actual producer of the content. There are copyright laws to protect such issues, but in the current scenario these laws are not adequately defined according to common global standards. With the help of blockchain technology, all copyrights can be saved in the form of intelligent contracts. Since blockchain is immutable, an entry that has once been stored in the blockchain cannot be changed or modified. The owner of the work has overall authority over ownership and distribution of the content.

    Identity management

    The world is becoming more digital every day. For example, if you want to conduct financial transactions online, you can easily access your money using your log-in details. In this case, however, no one can ensure the identity of the person moving the money. If someone compromises your username and password, they can do anything with your money. The need of the hour is to have a system that manages individual identification on the web. The distributed ledger technology used in blockchains gives you advanced methods of public-private encryption that you can use to prove your identity and digitize your documents. This unique secure identity can serve as your savior when conducting financial transactions or online interactions in a shared economy. In addition, the gap between different government agencies and private organizations can be closed by a universal online identity solution that blockchain can offer.

Obituary Professor Philipp Sandner 1980 - 2024!

We are very sad about the sudden passing of Professor Philipp Sandner, a top expert in digital assets in Germany. He was a leader and one of the most important people in blockchain technology and crypto-assets. He died at only 43 years old, leaving a big gap in the German and international blockchain community. Professor Sandner was more than just a teacher. He was a leader who understood the importance of Bitcoin and blockchain long before others did. He started a blockchain institute at the Frankfurt School of Finance & Management. He shared his knowledge and made a place for people to talk and grow in blockchain. His work, including writing a lot and organizing big conferences, made him well-known beyond Germany. As a speaker, podcaster, and always being at conferences, he was a hardworking and passionate supporter of his field. Philipp Sandner was good at making hard ideas easy for everyone to understand. His love and excitement for blockchain inspired many young people to learn and get involved in this field. His work and being at conferences helped make blockchain and crypto-assets taken seriously as technologies of the future. Losing him is not just a big loss for the science community but also a personal loss for those lucky to know and work with him. We remember Professor Philipp Sandner as a passionate, committed, and inspiring visionary. His legacy lives on in many projects and initiatives he started, and in the hearts and minds of those he inspired. Philipp leaves behind a wife and two young children. We send our deepest condolences and sympathy to his family for their great pain and loss. Our thoughts are with his family, friends, and colleagues in this tough time. We will miss Philipp. We have asked people from the blockchain community to share their memories and thoughts about Philipp Sandner. We kept this message in German, without hashtags or other elements.

Our call to the blockchain community: Let's honor Philipp Sandner's memory by turning skepticism, backwardness, and general criticism of crypto and Bitcoin into an open and accepting attitude. We should act with expertise and understanding of the opportunities of this century, for which Philipp Sandner was so passionate.

Bitcoin Whitepaper

In solidarity with other leading organisations from the blockchain and crypto community, we are linking to the Bitcoin whitepaper on our web presence.

We believe that Bitcoin being open source, maintaining access to the Bitcoin whitepaper is essential to inform others about the beginning of DLT and Blockchain technology.

We oppose the legal threats against two key contributors to the Bitcoin whitepaper and hope that this page will recall the spirit in which Satoshi Nakamoto first published his groundbreaking message about the peer-to-peer electronic cash system in 2009.
