Calypso is an auditable data-management framework that allows decentralize sharing and life-cycle management of private data. It is describe in this paper: https://eprint.iacr.org/2018/209.pdf. We use Calypso to store private data on the blockchain. DARCs describe the access to this private data. We use it in an example game of rock-paper-scissors in our example mobile application. (…)
C4DT is working on bringing software from the labs to the real world. As part of this effort, we’re working on implementing use-cases for OmniLedger. OmniLedger is a novel blockchain that offers several new features. For example it works as a decentralised login service. This means that there is no central service deciding on who (…)
Current access rights management systems always depend on a centralized authority that all members must trust. However, for blockchains, this is not a good solution. Blockchains are decentralized and cannot easily use centralized trust systems. We built DARCs, a group-management on steroids that allows decentralized administration and delegation of identities. It is used in the (…)

Every week at our engineers-meeting we have a short presentation of _anything_ we found on the internet that is somewhat work-related and that we would like to share with our fellow engineers. As the team-lead, I wanted to do some short team-building exercise, and I thought about the game “The Mind”. It is a collaborative (…)

The C4DT Factory works using software produced by the EPFL IC labs. Our focus is on software that increases digital trust in the era of the internet. One area where we see a lack of trust is account management, which includes the following elements: self-sovereign management of the account using the account to login to (…)
The DEDIS lab at EPFL worked on a novel blockchain system called OmniLedger. It uses Calypso to provide decentralized access control including secure storage of data on a blockchain. This combination has the following characteristics: OmniLedger builds on byzcoin, a permissioned, public blockchain which uses little energy. Contrary to other permissioned blockchains, it still allows (…)
For a bit more than three years, DEDIS has been working on a blockchain based on the byzcoin paper. The groundwork has been laid to add client interactions, first as a number of command line interfaces, then a first web-interface, a second interface added by C4DT as a demonstrator, and now, finally, a mobile app (…)
When working on the command line, it is common to build complex commands that connect sub-tasks through the pipe. In those situations, it can be useful to have an idea of the data transferred between two connected processes. For example, what is the throughput? What about the volume of data transferred? Enter pv. You can (…)
Most projects need organization. There exists a bunch out there, from the post-its laying on the desk to a huge kanban spanning the whole chain of supply. With code¸I find using the same layout as the project is pretty practical: when digging deeper inside it, you get more relevant information, tagging these closer to the (…)
Protecting your SME from cyberattacks is often complicated: costs of IT security audits, absent or overly complex standards, lack of internal skills have discouraged more than one company from confronting these risks.
Born from a participative approach, the Label cyber-safe.ch helps SMEs and other small organizations to manage their cyber risks pragmatically. Since December 9, a free tool allows to easily assess the exposure of an SME on the website www.cyber-safe.ch.

The Center for Digital Trust is always searching for novel ways to decentralize control of users accounts so we don’t have to rely on a centralized structure that can be abused by administrators. Currently we have three kinds of services that we offer to our partners: A matrix.c4dt.org installation for internal discussions Our demo.c4dt.org demonstrators (…)
The rising importance of data has thrown up new challenges ranging from competition policy to privacy to the geostrategic implications of 5G. The goal of this conference, organized in collaboration with The Graduate Institute in Geneva (IHEID), is to boost understanding of what data is and help to develop mindsets and attitudes that are based on technical and economic realities rather than the myths and shallow discussions that so often appear in popular media.

The cryptocurrency Bitcoin is limited by its astronomical electricity consumption and outsized carbon footprint. A nearly zero-energy alternative sounds too good to be true, but as C4DT-affiliated Professor Rachid Guerraoui explains, it all comes down to our understanding of what makes transactions secure. DCL’s new system, dubbed Byzantine Reliable Broadcast, can achieve safe cryptocurrency transactions on a large scale with an energetic cost of virtually zero.
