Scientific research has relied on open data for historical data. Its constant availability allows scientists to use them at any time they desire. These data are often hosted in repositories that are either centralized in one location or duplicated in a few locations. However, the availability of open data can be threatened for various reasons, include those of technical or political nature. Should these data become unavailable, it will hamper research reliant on such data. To resolve the concerns of potential obstruction of accessibility, this paper proposes to mitigate such risks by hosting open data in a distributed manner. Distributed hosting will prevent an actor to obstruct access to open data, as the data will be constantly duplicated in an indefinite number of locations.As an approach to implement the proposal above, this research will use the InterPlan- etary File System (IPFS). At the same time, we will use the Bitcoin blockchain to timestamp these data in order to prove their existence at given dates. Based on the results of the experiment, IPFS can serve data with just as much utility as centralized methods, allowing data to be accessible almost as soon as it is uploaded.
