TU Professor Sebastian Faust's cryptography project receives ERC grant funding
The European Research Council (ERC) is providing around two million euros of funding for a project at the Technical University of Darmstadt that aims to improve decentralised blockchain technologies. The project “CRYPTOLAYER – Cryptography for Second Layer Blockchain Protocols” by Computer Science professor Sebastian Faust is being supported with a renowned ERC Consolidator Grant for a term of five years. This will further strengthen TU Darmstadt's activities in cryptography and IT security research.

“Responsible Vulnerability Disclosure in Cryptocurrencies”
The article discusses the challenges of disclosing bugs and dealing with disclosures in open and distributed cryptocurrencies. Bugs in blockchain based systems can lead to severe security and privacy problems. Sometimes, these issues are resolved without much fanfare following a disclosure by the individual who found the hole. In other cases, they result in costly losses due to theft, exploits, unauthorized coin creation, and destruction. These experiences provide regular fodder for outrageous news headlines. In this article, we focus on the disclosure process itself, which presents unique challenges compared to other software projects.

“Deterministic Wallets in a Quantum World”
Most blockchain solutions are susceptible to quantum attackers as they rely on cryptography that is known to be insecure in the presence of quantum adversaries. In this work we advance the study of quantum resistant blockchain solutions by giving a quantum resistant construction of a deterministic wallet scheme.
