چکیده

Electronic inter-organizational relationships are governed by contracts regulating their interaction. It is necessary to run-time monitor the contracts, as to guarantee their fulfillment. The present work shows how to obtain a run-time monitor for contracts written in CL, a formal specification language which allows to write conditional obligations, permissions and prohibitions over actions. The trace semantics of CL formalizes the notion of a trace fulfills a contract. We show how to obtain, for a given contract, an alternating Büchi automaton which accepts exactly the traces that fulfill the contract. This automaton is the basis for obtaining a finite state machine which acts as a run-time monitor for CL contracts.

A Theoretical Basis for Run-time Monitoring of Contracts

Electronic inter-organizational relationships are governed by contracts regulating their interaction. It is necessary to run-time monitor the contracts, as to guarantee their fulfillment as well as the enforcement of penalties in case of violations. The present work shows how to obtain a run-time monitor for contracts written in CL, a specification language that allows writing conditional oblig...

Static Contract Simplification

Contracts and contract monitoring are a powerful mechanism for specifying properties and guaranteeing them at run time. However, run time monitoring of contracts imposes a significant overhead. The execution time is impacted by the insertion of contract checks as well as by the introduction of proxy objects that perform delayed contract checks on demand. Static contract simplification attacks t...

Examining the role of Smart Contracts in the development of the electronic registration system of documents

The document registration system is one of the most important instruments for guaranteeing the rights of individuals and preventing the occurrence of many disputes. In many developed countries, attempts have been made to change the system of registering transactions and documents. Thus, countries like the United States and Britain have changed the status of electronic registrations by adopting ...

TreatJS: Higher-Order Contracts for JavaScript

TreatJS is a language embedded, higher-order contract system for JavaScript which enforces contracts by run-time monitoring. Beyond providing the standard abstractions for building higher-order contracts (base, function, and object contracts), TreatJS’s novel contributions are its guarantee of non-interfering contract execution, its systematic approach to blame assignment, its support for contr...

Run-Time Monitoring of Fixed-Contract Interruptible Algorithms

Anytime algorithms give intelligent real-time systems the ability to trade deliberation time for quality of results. This capability is essential in domains where computing the optimal result is not computationally feasible or is not economically desirable. Examples of such domains include avionics, air traffic control, process control and missioncritical computations. Run-time monitoring of an...
