Ethereum smart contracts are programs that run inside a public distributed database called a
blockchain. These smart contracts are used to handle tokens of value, can be accessed and …

There are many approaches for automated software verification, but they are either
imprecise, do not scale well to large systems, or do not sufficiently leverage parallelization …

While model checking safety of infinite-state systems by inferring state invariants has
steadily improved recently, most verification tools still rely on a technique based on bounded …

Concolic testing is popular in unit testing because it can detect bugs quickly in a relatively
small search space. But, in system-level testing, it suffers from the symbolic path explosion …

Abstract Bounded Model Checking (BMC) is a popularly used strategy for program
verification and it has been explored extensively over the past decade. Despite such a long …

We present cpa-Daemon, a microservice for continuous software verification of C code. cpa-
Daemon provides full access to the verifier CPAchecker, but adds a clear network interface …

Modern software-verification tools need to support development processes that involve
frequent changes. Existing approaches for incremental verification hard-code specific …

Interpolation is becoming a standard technique for over-approximating state spaces in
software model checking with Satisfiability Modulo Theories (SMT). In particular when …

Interpolating, ie, computing safe over-approximations for a system represented by a logical
formula, is at the core of symbolic model-checking. One of the central tools in modeling …

We present UPPROVER, a bounded model checker designed to incrementally verify
software while it is being gradually developed, refactored, or optimized. In contrast to its …
