After publishing my chapter “Blockchain-Based Finance for Advancing Astronomy and Astrophysics” in the CFBA 2025 proceedings, I found myself thinking more deeply about one of the underlying themes of that research — trust.

In astronomy, and in most data-intensive sciences, collaboration is essential. Teams across countries share observations, algorithms, and instrumentation data to make discoveries that no single researcher could achieve alone. Yet, despite all our technological progress, one of the greatest challenges in modern science remains coordination. Datasets are often fragmented across institutions, funding records lack transparency, and attribution for discoveries can become blurred over time.

That’s where blockchain and decentralized data infrastructures present an intriguing possibility. These technologies are not just about cryptocurrencies or finance; at their core, they are about maintaining transparent, verifiable records — a digital paper trail that no single entity controls. Imagine a global research network where every dataset upload, code contribution, or funding transaction is securely timestamped, attributed, and traceable. Such a system could make scientific collaboration more open, accountable, and resilient to data loss or manipulation.

Recent work in this area is promising. Mora et al. (Frontiers in Big Data, 2024) explored token-based incentive systems that reward data sharing and peer validation, while Singh and Hein (Nature Digital Infrastructure, 2023) demonstrated how distributed storage can preserve research metadata and ensure long-term reproducibility. Together, these studies suggest that blockchain can act as the “invisible infrastructure” of scientific trust — linking researchers not through institutions, but through shared accountability.

Of course, technology alone cannot solve the cultural and ethical dimensions of collaboration. True openness requires a mindset shift: one that values transparent data exchange as much as it values publications and citations. My own view is that interoperability — connecting blockchains and data systems across different scientific fields — will be the next big step. Astronomy, climate science, and biomedical research all generate massive open datasets, yet each operates in silos. If these domains could communicate through interoperable, privacy-aware ledgers, we could unlock a new era of cross-disciplinary discovery.

At its heart, this idea isn’t just about blockchain or data. It’s about restoring something fundamental to science: the ability to trust what we share.
