The Editorial Team at Ledger wishes to remind authors that the submission deadline (31 December 2015) for the journal's inaugural edition is rapidly approaching. We welcome papers of up to four thousand words detailing new ideas and perspectives on any relevant topic, including but not limited to the technical, social, economic, and philosophical developments and implications of Bitcoin, cryptocurrencies, public and decentralized ledgers, distributed consensus, and more. Interested authors should consult the submissions and policies sections on the Ledger website for more details on our focus and scope, submission methods, transparent peer-review process, author guidelines, and open-access policy. We will consider submissions after 31 December 2015 for subsequent issues on an ongoing basis.
