Since 2008 the cryptocurrency market has revolutionised the world by innovating and expanding into other areas (e.g., finance and art). However, with this rapid expansion, many projects are created every day, giving rise to a wide and varied range of websites, technologies and scams. Markets follow financing stages and it is during an initial stage of euphoria that more projects are created.
We believe that as the cryptocurrency market stabilises, projects/websites are disappearing because funding diminishes or runs out.
Arquivo.pt initiated a new web archive collection that preserves web content that documents Cryptocurrency activities.
This work produced a new open dataset with information documenting each cryptocurrency project, including it is original URLs and links to the corresponding web-archived version in Arquivo.pt. The information sources selected to create this dataset were:
We believe that by creating this new dataset related to cryptocurrencies and by preserving all the corresponding web content, it has the potential to originate innovative scientific contributions in several areas such as Economy or Digital Humanities.

Arquivo.pt is a service operated by the Fundação para a Ciência e Tecnologia I.P. that preserves data published on the Web between 1996 and the present day, making them accessible to any citizen for memory and research purposes.
EU open data directive includes documents on websites
“(30) This Directive lays down the definition of the term ‘document’ and that definition should include any part of a document. The term ‘document’ should cover any representation of acts, facts or information — and any compilation of such acts, facts or information — whatever its medium (paper, or electronic form or as a sound, visual or audiovisual recording.
(34) To facilitate re-use, public sector bodies should, where possible and appropriate, make documents, including those published on websites, available through an open and machine-readable format and together with their metadata, at the best level of precision and granularity, in a format that ensures interoperability
(35) A document should be considered to be in a machine-readable format if it is in a file format that is structured in such a way that software applications can easily identify, recognise and extract specific data from it. Data encoded in files that are structured in a machine-readable format should be considered to be machine-readable data. A machine-readable format can be open or proprietary. They can be formal standards or not.
(60) The Commission should facilitate the cooperation among Member States and support the design, testing, implementation and deployment of interoperable electronic interfaces that enable more efficient and secure public services.
Arquivo.pt is a public service that has the mission of preserving documents published on Internet sites to enable their long-term open access and provides interoperable electronic interfaces (APIs) for their automatic processing.
Any citizen can access the open data resulting from these historical archives and, for example, search for official information published on the websites of successive governments.
In 2021, Arquivo.pt provided open access to over 10 billion files (721 TB) from 27 million websites. The open data preserved by Arquivo.pt can be explored through the search interface, automatically through API (https://arquivo.pt/api) or by reusing derived datasets.
Derived datasets available on the Open Data Portal
Besides the original web artefacts preserved at Arquivo.pt, this service has generated open datasets derived from its activities, which are now available in open access so that they can be reused:
