Modern clouds depend crucially on an extensible ecosystem of thousands of controllers,
each managing critical systems (eg, a ZooKeeper cluster). A controller continuously …

International payments are slow and expensive, in part because of multi-hop payment
routing through heterogeneous banking systems. Stellar is a new global payment network …

In this paper we propose a novel human-centered approach for detecting forgery in face
images, using dynamic prototypes as a form of visual explanations. Currently, most state-of …

Formal verification is a promising approach to eliminate bugs at compile time, before they
ship. Indeed, our community has verified a wide variety of system software. However, much …

Distributed systems are complex and difficult to build correctly. Formal verification can
provably rule out bugs in such systems, but finding an inductive invariant that implies the …

Ivy is a multi-modal verification tool for correct design and implementation of distributed
protocols and algorithms, supporting modular specification, implementation and proof. Ivy …

This paper surveys the work to date on Ivy, a language and a tool for the formal specification
and verification of distributed systems. Ivy supports deductive verification using automated …

Quantified first-order formulas, often with quantifier alternations, are increasingly used in the
verification of complex systems. While automated theorem provers for first-order logic are …

In 2014, Heizmann et al. proposed a novel framework for program termination analysis. The
analysis starts with a termination proof of a sample path. The path is generalized to a Büchi …

We study the classical problem of verifying programs with respect to formal specifications
given in the linear temporal logic (LTL). We first present novel sound and complete …
