Summary of Project Atlas Report

Project Atlas is a data platform developed to map and analyze decentralized finance (DeFi) and crypto markets, addressing the need for reliable and tailored data for central banks and financial regulators. The platform, created by the Eurosystem and partners, fuses on-chain data from blockchains with off-chain data from crypto exchanges to provide insights into macroeconomic relevance and cross-border capital flows.

Key challenges include the lack of transparency in crypto markets, unreliable data reporting, and difficulties in mapping global flows due to pseudo-anonymity and regulatory gaps. The architecture employs a cloud-based medallion architecture with bronze, silver, and gold layers for data ingestion, processing, and storage, along with an analytics environment using tools like Apache Spark for flexible analysis and dashboards for visualization.

A proof-of-concept focuses on Bitcoin flows between crypto exchanges, using attribution data to estimate cross-border flows as a lower-bound proxy. This highlights significant but growing flows, offering structural insights into economic impacts. Dashboards visualize metrics such as on-chain transactions, cross-border flows, and comparisons between on-chain and off-chain activity.

Benefits include enhanced data reliability, improved risk assessment for financial stability, and support for policymakers and researchers. Future steps involve expanding data sources, incorporating other blockchains, and sharing insights as an open public good.

Overall, Project Atlas addresses data gaps in the dynamic crypto ecosystem, enabling more informed decisions and fostering better understanding of DeFi's role in global finance.
