Scalability has become a de facto non-functional requirement for today’s Internet applications that start small and aim to become a huge success. The ability of the system to automatically scale is required by the dynamic nature of the workload experienced by these applications. In this context, the DEPAS (Decentralized Probabilistic Auto-Scaling) algorithm assumes an overlay network of computi...

Ethereum contracts can be designed to function as fully decentralized applications called DAPPs. Many DAPPs have already been fielded, including an online marketplace, a role playing game, a prediction market, and an Internet service provider. Unfortunately, DAPPs can be hacked, and the assets they control can be stolen. A recent attack on an Ethereum decentralized application called The DAO de...

Large and complex decentralized systems with au tonomous components often require appropriate mech anisms for cooperation reliability and dynamic recon guration It is crucial that these mechanisms allow the system to execute continuously for a long period of time with minimal disruption despite failure or recon guration of some components They should also allow various components to interact in...

The procedure for independent design of robust decentralized controllers proposed by Skogestad and Morari is improved by requiring that each individual controller is of the internal model control (IMC) type. It is shown how to find bounds on the magnitude of the IMC filter time constants such that robust stability or performance is guaranteed. In contrast, Skogestad and Morari found bounds on t...

The inefficiency of decentralized decision-making is one of the most influential findings of the supply chain coordination literature. This paper shows that with the possibility of continuing trade, decentralization can be beneficial in improving supply chain performance. In a supply chain with decentralized decision-making and continuing trade, it is easier to incentivize players to coordinate...

The wisdom of the crowd is a valuable asset in today’s society. It is not only important in predicting elections but also plays an essential rôle in marketing and the financial industry. Having a trustworthy source of opinion can make forecasts more accurate and markets predictable. Until now, a fundamental problem of surveys is the lack of incentives for participants to provide accurate inform...

Considerable research effort has recently been devoted to the design of structured peer-to-peer overlays, a term we use to encompass Content-Addressable Networks (CANs), Distributed Hash Tables (DHTs), and Decentralized Object Location and Routing networks (DOLRs). These systems share the property that they consistently map a large space of identifiers to a set of nodes in a network, and while ...

Since Autonomous Decentralized Systems have been proposed in 1977 and published [1], their technologies and applications in control and information fields have progressed and some of their technologies are approved as the de-facto standards of ODVA (Open DeviceNet Vendor association), OMG (Object Management Group), etc. Recently the ADS have been accelerated more under the unpredictable recent ...

East Japan Railway Company has created new businesses such as life-style business and information technology business on the basis of railway business for sustainable growth. These businesses generate and provide synergy to one another effectively because each business is autonomous decentralized system based on diversified infrastructure. The infrastructure includes not just structure but mana...

Blockchain is one of several technologies du jour. It combines clever methods from peer-to-peer decentralized computing to provide an online tracing function for virtual transactions, and, once someone sets it up, it requires minimal intervention from a central auditor. While Bitcoin is the most well-known application of this innovative computer science, verification of authenticity and identit...
