2nd Workshop on “Blockchain Technologies and Applications:
Towards Blockchain-Based Collaborative Enterprise”


Nowadays, we witness the emergence of new collaborative business models such as virtual market places, sharing economy, Remote Fabrication and distributed supply chain. This has been geared by the rise of new IT technologies, namely Internet of Things technologies and cloud computing.

Despite the advantages of these scenarios, managing security and trust are major obstacles that should be studied to spread the collaboration intensive business.

One of the most promising technology that can cope with these issues is distributed ledger technology. Distributed ledger technology e.g. Blockchain is a technology that provides a decentralized “database” on a network that is scalable, secure, tamper-proof, and accessible by each peer on the network. However, distributed ledger technologies are basically designed for financial application. Consequently, these technologies are, so far, not adapted to the development and the execution of collaborative business process necessary to meet business needs.

In this workshop, participants are invited to answer the questions: how to enable distributed ledger based infrastructures so that they can meet collaborative business needs? What are the fundamental obstacles in the current Distributed ledger technologies state that hinder the support of the business collaboration? At what levels in Distributed ledger architecture the changes are needed?
