Workshop on

Distributed Cryptocurrencies and Consensus Ledgers (DCCL 2016)
25th July 2016, Chicago (IL), USA


Co-located with PODC 2016 (http://www.podc.org)


The recent global interest in cryptocurrencies was triggered by the rise of
Bitcoin, which introduced a public ledger called the blockchain to record
the history of its transactions. Bitcoin maintains its blockchain through a
decentralized peer-to-peer cryptographic protocol that works without any
trusted central authority, but it assumes (at least) that a majority of the
computing power in the system is held by honest nodes. Cryptographic
techniques ensure the integrity of all transactions in the distributed
ledger and new entries are appended through a consensus protocol. Many
alternative cryptocurrencies have introduced variations of Bitcoin and
proposed alternative designs for consensus ledgers. Novel protocols, known
as "smart contracts", are constructed on top of the blockchain, achieving
guarantees that were not possible before. Today many financial institutions
see the disruptive power of this technology and regard it as a promising
alternative to their established business practices, not depending on
centralized control, eliminating intermediaries, and enabling new

Several consensus mechanisms are currently under investigation: On the one
hand, Bitcoin's consensus protocol, called "Nakamoto consensus", allows
anonymous nodes to participate based on a "proof-of-work". On the other
hand, traditional Byzantine consensus and BFT protocols play a role in
settings where all nodes are known to each other. Many other systems have
been proposed and lie somewhere between these extremes. Distributed
knowledge, consistency, and reaching consensus among selfish and mutually
distrusting nodes are core topics in the theory and practice of distributed
computing. Hence, the popularity of decentralized cryptocurrencies and
consensus ledgers creates a unique opportunity for the field to explore
this nascent domain and to influence it.

Call for Contributions

This workshop aims at discussing questions of consistency, concurrency,
distributed knowledge, integrity, and reaching consensus in the context of
cryptocurrencies and consensus ledgers. The workshop solicits submissions
describing current work addressing decentralized cryptocurrencies and
consensus ledgers, including analytical results, work on systems, and/or
position papers.

Topics of interest include, but are not limited to
* Distributed consensus among selfish nodes
* Scalability
* Mechanisms for consensus ledgers
* Proof-of-work and alternatives
* Byzantine fault tolerance
* Systems implementing distributed ledgers and blockchains
* Applications of blockchains to distributed computing
* Nakamoto consensus and protocols based on proof-of-work
* Smart contracts
* Anonymity and privacy
