safeFBDC partners at Gaia-X Hackathon

9 min readDec 7, 2021


Partners of safeFBDC, the research project of the Financial Big Data Cluster, joined the second Gaia-X hackathon to prototype the first Gaia-X use cases for the financial sector. In collaboration TechQuartier, spotixx, SAP Fioneer and Deloitte from the safeFBDC consortium with support of deltaDAO AG and Ocean Protocol explored Compute-to-Data during the two-day event in early December 2021.
During the Gaia-X hackathon safeFBDC contributed a use case to the “Compute-to-Data & DLT” track and the “Confidential Computing” track. The first use case “AML detection on graphs” aims to advance the development of detection methods for previously undetected cross-institutional patterns in money laundering.

Hackathon use case: “Compute-to-Data & DLT”

safeFBDC intends to iteratively train a global model across many data sources (e.g. Banks). Advanced implementations can entail continuous model aggregation and updates, split learning, randomization, and advanced consensus methodologies.

What is Compute-to-data?

Compute-to-Data is an approach that leaves the data where it is, with the owner, but takes the algorithm to the premise. This way a model can be trained on data of multiple data sources

  • without exposing any private data of any data source
  • without having a central authority that orchestrates the learning process
  • while the data owner keeps full control over their data and over algorithms that are trained on it
  • while the full process is transparent and written to an immutable audit trail

Compute-to-Data is especially suitable to remotely train machine learning models on data sets owned by different data providers without being dependent on a central authority. Using Compute-to-Data the data never leaves the premises of the data owners. The data owners remain the only entities in possession of the data. Owners only approve selected and trusted (vested) algorithms to access their data. So, the data owners never lose control over the data.

Minimal Viable Gaia-X Demonstrator — Implementation

Within the “Compute-to-Data & DLT” track of the hackathon deltaDAO and Ocean Protocol provided the Minimal Viable Gaia-X Demonstrator and a first reference implementation of the following Federation Services to facilitate this use case: Gaia-X Portal, Data Contracting Service & Access Controls, Trust & Identity, Data Exchange Logging Service and Federated Catalogue.

The safeFBDC portal acts as frontend to the trusted safeFBDC domain in which three data sets and two algorithms have been integrated to run in the secured Compute-to-Data cluster.

Access controls & data exchange logging services are based on distributed ledger technology (DLT) & smart contracts. Identity & trust services are based on the #opensource ESSIF compliant #SSI Kit by The pooling in the safeFBDC domain was enabled by providing a merging algorithm, while the consortium partners remain in strict control of the data at all times. At the heart of the use cases, besides the Gaia-X Federation Services, which are orchestrating and enabling this, is the privacy-preserving “Compute-to-Data” capability of Ocean Protocol. Their distributed ledger automatically creates audit trails and data collection plans that contribute to compliance, data access control and allow provenance of all data assets.

Contributions of the “Confidential Computing” track

The “Confidential Computing” track worked on the provisioning of a trusted execution and storage environment including the key management to create a foundation for the next hackathon and the on-demand creation of necessary infrastructures within the Gaia-X infrastructure, enabled by the Gaia-X Federation Services.

Synthetic Training Data and Algorithms from spotixx

The Frankfurt based startup and TechQuartier-member spotixx provided the necessary synthetic training data and algorithms to perform analytics on the individual and the pooled data. The graph algorithm aims to

  • uncover complex networks of criminal actors and organisations,
  • track the movement of illicit funds across the entire financial system, traversing multiple persons and institutions
  • detect unknown illegal activity that would be impossible to perceive looking at one bank alone

Overall and confidential computing architecture from SAP Fioneer, Deloitte Consulting and TU Darmstadt

SAP Fioneer, Deloitte Consulting and TU Darmstadt collaborate within safeFBDC at the Hackathon to identify new secure and data sovereignty preserving data architectures for safeFBDC Use Cases to exchange data between financial institutes.

Background: What is the safeFBDC?

safeFBDC is a research project funded by the Federal Ministry for Economic Affairs and Energy (BMWi) and orchestrated by TechQuartier. The aim of the project is to enable cross-institutional use of financial market data while preserving individual data sovereignty. It is the use case of Gaia-X in the financial domain and shall serve as a blueprint for data ecosystems made in Europe. For the project time from 2021 to 2023 a consortium, under the leadership of TechQuartier, which is made up of eleven founding and 30+ associated partners covering a large part of the German financial industry and beyond, was formed.

Its goal is to create a unique financial data platform that respects European values and data sovereignty while bringing flexibility, scalability and robustness to state of the art research in Machine Learning and AI to optimize business processes and develop new, data-driven solutions.

Five use cases covering the impact of climate risks on financial markets, the fight against money laundering and improved predictability for monetary policies as well as Stable Supply Chain Finance are researched, developed and prototypically validated using artificial intelligence and machine learning. The interest in the successful realization of safeFBDC is not limited to actors of financial markets; it is intended to serve the greater public good. This is a unique opportunity to establish a strong data ecosystem for the financial services market in Germany.

Consortial leader TechQuartier

As consortial lead of the safeFBDC, TechQuartier supports the evaluation of the demonstrator and the further development of the infrastructure together with the partners into the reference use case for the financial piece in Gaia-X. Many of the startups and partners are already established within the TechQuartier community, whose connections also enable trend scouting and innovation brokerage to this research project.

“Since data is a highly valued commodity of the digital age, we need to ensure the competitiveness of German and European companies and research institutions by giving them safe access to reliable and clean financial data. Currently, this data is being stored in individual financial silos and is not available to the innovators and thinkers who are creating new data-driven solutions for topics like climate risk management and anti-money laundering,”

spotixx GmbH was founded by a team of financial crime experts in 2019 with a goal to use Artificial Intelligence to improve the detection of criminal activity in the financial system. Today spotixx delivers on this goal by providing machine learning driven solutions that help financial organisations fight against fraud and money laundering.
For fraud prevention spotixx deploys intelligent automated agents either in the cloud or locally within a customers infrastructure to analyse and learn from their transactional data and build human readable rulesets that can be used directly to detect fraudulent transactions. The spotixx agents automatically learn and adapt to new criminal behaviours as they emerge, ensuring that the rulesets for detection are always up to date and effective. For money laundering prevention spotixx analyses network graphs in both single and multi-institutional data to highlight patterns of criminal activity. Spotixx models can be used for direct detection of money laundering or as a complementary tool to other detection paradigms to suggest when likely false positive alerts can be auto-closed, allowing for financial institutions to direct resources towards productive investigations and save costs.
