Blockchain

Ever since the inception of Bitcoin in 2008, the idea of a digital currency which no single party controls fascinated researchers and entrepreneurs worldwide. Its potential to disrupt the financial industry sparked research efforts and attracted large scale investments.

However, the truly disruptive innovation of Bitcoin was not the cryptocurrency, but the underlying technological concept of a blockchain. A blockchain is an immutable and censorship resistant shared append-only database built on top of a peer-to-peer network. For the first time, there are non-duplicable digital assets.

These properties enable applications to replace costly trust management with peer-based verification and decentralized control. Hence, blockchains have a huge potential to disrupt entire industries by replacing trusted parties in business processes and applications. Besides disintermediation, blockchain technology can also be used to create an immutable and irrefutable record of events making it attractive in auditing and reporting scenarios.

Advanced blockchains beyond the original bitcoin technology, e.g., Ethereum, support the decentralized execution of complex code commonly referred to as smart contracts and with that provide a platform for the development of decentralized applications.

In ISE, we employ our deep knowledge and experience in distributed systems as well as databases to analyze, deploy and advance blockchain technology in order to solve today's societal and business challenges.

We work on and explore projects both with large enterprises, start-ups, and blockchain developers to tackle pushing problems in the blockchain ecosystem. Our topics include:

     

  • Decentralized application architecture design and integration
  • Performance, security, and privacy in enterprise settings using permissionless and permissioned blockchains
  • Software engineering practices for blockchain-based applications and Smart Contracts, e.g. off-chaining computations
  •  

As part of our ISE teaching portfolio, we offer several courses incorporating blockchain technologies from both, a theoretical and a practical point of view.
