As we are not aware of any daily updated repositories for scientific blockchain papers, we have started building one. Our main sources are the two arXiv categories cs.CS and q-fin. We have created some categories, and papers appear under one category only. We hope to update this list daily.
This is the link to the repository: https://www.cudominer.com/blockchain-related-papers/
This list was started around the end of April. We will try to add as many past papers as we can, but feel free to send us any relevant links to more papers. Likewise, if you feel a paper should belong to another category just let us know. Participation is most welcome!
For any suggestions or questions please contact us on firstname.lastname@example.org.
