Welcome to QUASAR

We offer professional services to explore & design products and solutions using blockchain technologies across various industries.

Our services are used by financial service companies who are starting to collaborate with specialised FinTech businesses to complement and strengthen their in-house innovation strategy. A typical use case is how a blockchain can be adopted to process a wide range of financial transactions in a more efficient and cost-effective way. We share a passion for building solid software. Our developers have extensive experience and have worked on complex, scalable and mission-critical enterprise applications for large corporate clients. We use Agile methodologies throughout all of the interaction with our clients, from business idea capture through delivery processes to technical implementation. We know what it is to deliver data-centric and user-friendly solutions which must meet stringent requirements for security, compliance, administration and maintenance.

The Quasar Network uses blockchain technology to create a new infrastructure that uses the Quasar Distributed Ledger to quickly and easily enable peer-to-peer (micro-)transactions between enterprises, consumers and the Internet of Everything (IoE).

The Quasar Network platform addresses the evolving market of 50 billion IoT devices –  a market with completely new requirements for payments (like instant, irreversible micro payments between autonomous operating appliances) which cannot as easily be addressed by traditional payment systems.

This, in turn, makes payments between „Things“ possible. Quasar instantly processes peer-to-peer micropayments, making the money immediately available in the user’s (or machine’s) digital wallet.

The Quasar Network platform thus offers a gateway between traditional bank accounts and digital wallets. This gateway enables a 1:1 conversion between fiat and digital money, eliminating volatility risk exposure for users. Through its data-sensitive design, the Quasar Network platform is compliant with regulations and fully scopes user privacy.

  • permissioned and permissionless blockchains

  • cryptocurrency
  • multisig wallets and security
  • compliance
  • smart contracts
  • blockchain-based escrow services
Blockchain consultancy

Quasar offers professional services to explore emerging blockchain technologies and to understand the potential impact for various industries.


Joint workshops are organised to understand the need, goal(s) and establish Key Performance Indicators. Following the workshops we use the insights gained to create design concepts and share these for feedback and approval.


After acceptance of the proposed concept design, we start prototyping, using software visualisation techniques. This is an iterative process which allows for direct feedback and implementation of users’ requests. Relevant sample data is used in the project to simulate a real life environment.


Building on the Proof of Concept and with a focus on speed of delivery while maintaining quality, we can start immediately with an infrastructure ready from the day we begin working on a specific client project.
