COVID-19 UPDATE
===============

After assessment of the COVID-19 Pandemic, the ESORICS 2020 Organizing
Committee has made the decision to move the conference and all
associated workshops to an online format. Arrangements for the virtual
format are being made and we will post updates as they are announced.
This new format will not affect our proceedings, which will be
published as Springer LNCS proceedings.

WORKSHOP HISTORY
=================

Since the appearance of Bitcoin in 2009, a plethora of new
cryptocurrencies and other blockchain based systems have been deployed
with different success. While some of them are slightly different
copies of Bitcoin, other ones propose interesting improvements or new
usages of the underlying blockchain technology. However, the novelty
of such technologies is often tied with rapid developments and
proof-of-concept software, and rigorous scientific analyses of the
proposed systems are often skipped.

This workshop aims to provide a forum for researchers in this area to
carefully analyze current systems and propose new ones in order to
create a scientific background for a solid development of new
cryptocurrencies and blockchain technology systems.

The main topics include (but are not limited to):

* Anonymity and privacy in cryptocurrencies.
* Privacy-preserving technologies.
* Cryptocurrency based trust systems.
* Security analysis of existing cryptocurrencies.
* Formal threat models in cryptocurrency systems.
* Improvement proposals for existing cryptocurrencies.
* P2P network cryptocurrencies analysis.
* Private transactions in blockchain based systems.
* Consensus mechanisms: proof-of-work, proof of stake,
  proof of burn, proof-of-useful-work.
* New usages of the blockchain technology.
* Scalability solutions for blockchain systems.
* Smart contracts.

===================
SUBMISSION DETAILS
===================

Regular and short papers must be original and not submitted for
publication elsewhere. Authors are invited to submit their manuscripts
following the LNCS Proceedings Manuscript style. Papers are limited to
16 pages (full papers), or 8 pages (short papers) including references
and appendices, and can be submitted as PDF via the CBT 2020 submission
site: https://easychair.org/conferences/?conf=cbt2020

*Double blind review*: CBT requires anonymized submissions -- please
make sure that submitted papers contain no author names or obvious
self-references.

Accepted regular papers will be published by Springer in the LNCS
collection. At least one author of each accepted paper is required to
register and present their work at the workshop; otherwise the paper
will not be included in the proceedings.
