Adding concurrency to smart contracts

Modern cryptocurrency systems, such as the Ethereum project, permit complex financial transactions through scripts called smart contracts. These smart contracts are executed many, many times, always without real concurrency. First, all smart …

The computational structure of progress conditions and shared objects

We study the effect of different progress conditions on the computability of distributed systems. For a system with n processes, we define exponentially many new progress conditions and explore their properties and relative strength. We cover many …

Deciding and verifying network properties locally with few output bits

Given a boolean predicate on labeled networks (e.g., the network is acyclic, or the network is properly colored, etc.), deciding in a distributed manner whether a given labeled network satisfies that predicate typically consists, in the standard …

Efficient randomized test-and-set implementations

We study randomized test-and-set (TAS) implementations from registers in the asynchronous shared memory model with n processes. We introduce the problem of group election, a natural variant of leader election, and propose a framework for the …

Demand-aware network designs of bounded degree

Traditionally, networks such as datacenter interconnects are designed to optimize worst-case performance under arbitrary traffic patterns. Such network designs can however be far from optimal when considering the actual workloads and traffic …

About this journal

The international journal Distributed Computing provides a forum for original and significant contributions to the theory, design, specification, and implementation of distributed systems. Topics covered by the journal include but are not limited to: design and analysis of distributed algorithms; multiprocessor and multicore architectures and algorithms; synchronization protocols and concurrent programming; distributed operating systems and middleware; fault-tolerance, reliability, and availability; architectures and protocols for communication networks and peer-to-peer systems; security in distributed computing, cryptographic protocols; mobile, sensor, and ad hoc networks; internet applications; concurrency theory; and specification, semantics, verification, and testing of distributed systems. In general, only original papers will be considered. Papers previously presented in conference proceedings may be submitted in enhanced form. If a paper has appeared previously, in any form, the authors must clearly indicate this and provide an account of the differences between the previously appeared form and the submission.
