- Blockchain and Distributed Ledger Technologies
Blockchain and other Distributed Ledger Technologies change the way we deal with the issue of trust, the basis for all business relations. This paradigm shift enables a digital future with novel governance of organizations and business models: abandon centrally and hierarchically organized trust services of middlemen, reallocate their tasks in a decentralized network and reward each participant for his contribution to the maintenance of a healthy ecosystem.
Understand the capabilities and limitations of distributed ledgers.
Deep dive into the world of Ethereum, Quorum, Hyperledger Fabric and more.
Develop future-proof smart contracts and decentralized applications.
Ideate, evaluate and test prototypes of your blockchain use cases.
Design and implement your private blockchain network.
Make sure your distributed ledger applications have no critical vulnerabilities.
We participated in the joint review of the architecture with the goal to extend the wallet with scalable multi-currency support as well as in the development of the necessary feature extensions for enabling ETH and other Ethereum-based cryptocurrencies (ERC20 tokens). In the course of this development the mobile wallet was integrated with the Ethereum network using Infura and the web3j library and the new version of the user interface of the native Android app was redesigned providing e.g. real time exchange rates.
We designed the blockchain layer of a decentralized platform for the transport industry. Participants in a consignment share their data enabling them to optimize the planning and utilization of their resources. Scalability of the number of validators, throughput and latency as well as confidentiality of the transactions were key requirements. We evaluated a proof of concept comprising Parity and Quorum as the basis for an Ethereum-based consortium blockchain and Hyperledger Fabric as an alternative solution.
We set up of a permissioned blockchain for hosting providers and their clients to share an immutable log of system monitoring events relevant for the calculation and verification of SLA reports. Monitoring events are transmitted directly from the monitoring tools to the blockchain and can be observed by the clients immediately. We have implemented the blockchain layer using Hyperledger Fabric with a separate private channel for each client to keep its event log confidential.
We developed EtherLib, a decentralized marketplace for monetizing books their owners do not need anymore. The books are passed on from reader to reader, each of them compensating a portion of the original purchase price. After a certain number of transfers, the price of a book is split among all readers. Smart contracts on Ethereum govern the marketplace and the frontend, an Ionic mobile app communicates with the Ethereum network using web3.js and the Google Books API to retrieve master data of the books.
All-day workshop to become acquainted with the most important blockchain concepts. We show you how P2P networks and different consensus algorithms work, practice the design and the development of smart contracts and evaluate use cases for your organization.
