Call for papers for a special issue of the IEEE Security & Privacy
magazine on Blockchain Security and Privacy.
Manuscript submission: 1 February 2017
Publication date: Jan/Feb 2018


The blockchain emerged as a novel distributed consensus scheme that
allows transactions, and any other data, to be securely stored and
verified without a centralized authority. For some time, the notion of
blockchain was tightly coupled with Bitcoin, a well-known proof of
work hash-based mechanism. Today, there are more than one hundred
alternate blockchains. Some are simple variants of Bitcoin, whereas
others significantly differ in their design and provide different
functional and security guarantees. This shows that the research
community is in search of a simple, scalable, and deployable
blockchain technology. Various reports further point to an increased
interest in the use of blockchains across many applications and a
significant investment by different industries in their development.

The blockchain will likely induce considerable change to a large
number of systems and businesses.

Distributed trust, and therefore security and privacy, is at the core
of the blockchain technologies and has the potential to either make
them a success or cause them to fail.

This special issue aims to collect the most relevant ongoing research
efforts in blockchain security and privacy. Topics include, but aren't
limited to:

o   Platforms for decentralized consensus (Bitcoin, Ethereum, Stellar, Ripple, 
    Open Blockchain, etc.)
o   New threat models and attacks on existing blockchain technologies
o   Defenses and countermeasures
o   Simple payment verification modes and lightweight blockchain clients
o   Anonymity and privacy issues and measures to enhance anonymity and privacy
o   Proof-of-work, -stake, -burn, and other consensus alternatives
o   Scalability issues and solutions
o   Incentive mechanisms for blockchains
o   Economic, monetary, legal, ethical, and societal aspects
o   Applicability of the technology in financial markets
o   Regulation and law enforcement
o   Fraud detection and financial crime prevention
o   Case studies (for instance, of adoption, attacks, forks, and scams)
o   New applications

Submission Guidelines

Submissions will be subject to the IEEE Computer Society's
peer-review process. Articles should be at most 6,000 words, with a
maximum of 15 references, and should be understandable to a broad
audience of people interested in security, privacy, and
dependability. The writing style should be down to earth, practical,
and original. Authors should not assume that the audience will have
specialized experience in a particular subfield. All accepted articles
will be edited according to the IEEE Computer Society style
guide. Submit your papers to ScholarĀ­One at
