Volume 2 (2017) Is Now Complete!

The Editorial Team at Ledger would like to announce the completion of our second year of publishing excellent, peer-reviewed work on cryptocurrency and blockchain technology research! 

Many thanks go out to all those who chose to work with us this year, to those kind reviewers who dedicated their time and energy to making the peer-review process work, and to our readers, for staying with us all year.

In this volume we present five peer-reviewed papers:

"Equihash: Asymmetric Proof-of-Work Based on the Generalized Birthday Problem," by Alex Biryukov and Dmitry Khovratovich,

"Bitcoin Mining as a Contest," by Nicola Dimitri,

"From Smileys to Smileycoins: Using a Cryptocurrency in Education," by Gunnar Stefansson and Jamie Lentin,

"What Diplomacy in the Ancient Near East Can Tell Us About Blockchain Technology," by Chris Berg, and

"Funding Science with Science: Cryptocurrency and Independent Academic Research Funding," by Edward Lehner, Dylan Hunzeker, and John R. Ziegler.

We hope you will take some time to give them a read!

We would also like to take this moment to remind you that our call for papers is always open, and that we publish on a rolling basis as papers clear the peer-review process. We already have some papers in the works that will be appearing in early 2018, so check back for more soon.

Once again, from the Editorial Team at Ledger, we would like to thank you for another great year.

See you in 2018!
