N1 - Funding Information:
The functionality of the collaboration service is supported by an (Open) API. Other services are therefore able to use the API in order to interact with the collaboration service. Hence, the API abstracts the complexity of the blockchain infrastructure and provides a generic collaboration interface to other services. In this context, it also enables publish-subscribe message interactions from the blockchain infrastructure to a message bus infrastructure (like Apache Kafka) and vice versa.

N2 - Recent security incidents in the finance sector have demonstrated the importance of sharing security information across financial institutions, as a means of mitigating risks and boosting the early preparedness against relevant attacks. However, financial institutions are in several cases reluctant to share security information beyond what is imposed by applicable regulations. In this paper, we introduce a blockchain-based solution for sharing security information in a decentralized way, which boosts security and trust in the information sharing process. We also illustrate how the information that is shared across financial institutions can serve as a basis for collaborative security services such as risk assessment.
