In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of a system with respect to a certain formal specification or property, using formal methods.
System types that are considered in the literature for formal verification include finite state machines (FSM), labelled transition systems (LTS) and their compositions, Petri nets, timed automata and hybrid automata, cryptographic protocols, combinatorial circuits, digital circuits with internal memory, and abstractions of general software components.
Usually formal verification is carried out algorithmically. The main approaches to implementing formal verification include state space enumeration, symbolic state space enumeration, abstract interpretation, abstraction refinement, process-algebraic methods, and reasoning with the aid of automatic theorem provers such as HOL or Isabelle.
Verification Sponsors are organizations or individuals that are supplied by the registrant that can supposedly confirm the eligibility of the registrant for the domain name.
Verification Partners are organizations that dotCoop has contracted with in locations around the world that agree to be contacted by dotCoop for verification assistance for registrations from particular countries.
Verification Partners are asked to respond within the time specified in their agreement with a recommendation based on the information they have about the registrant or that they can elicit from the Verification Sponsors.
