The permanence paradox in decentralized storage and the mutable nature of scientific knowledge

Centralized data repositories are foundational to the open science movement, yet they face persistent challenges that threaten the long-term viability of the FAIR data principles. Issues of sustainability, cost, and vulnerability to single points of failure cast doubt on whether today’s data will remain Findable and Accessible for future generations. Emerging decentralized storage technologies, like the InterPlanetary File System (IPFS) and blockchain-based platforms such as Arweave, propose a paradigm shift toward data permanence, integrity, and resilience. This commentary explores the potential of these systems to create a more robust and censorship-resistant scientific record. It evaluates the benefits, including long-term preservation and verifiable data integrity that enhance Reusability, against significant obstacles such as usability, governance, and economic sustainability. While decentralized storage is not a panacea, its principles warrant serious consideration. This commentary advocates for a hybrid model that integrates the strengths of centralized and decentralized systems, ensuring that the scientific record remains FAIR for generations while addressing the challenge of managing the evolution of scientific knowledge within a permanent system.
