Mechanisms for Outsourcing Computation via a Decentralized Market
As the number of personal computing and IoT devices grows rapidly, so does
the amount of computational power that is available at the edge. Since many of
these devices are often idle, there is a vast amount of computational power
that is currently untapped, and which could be used for outsourcing
computation. Existing solutions for harnessing this power, such as volunteer
computing (e.g., BOINC), are centralized platforms in which a single
organization or company can control participation and pricing. By contrast, an
open market of computational resources, where resource owners and resource
users trade directly with each other, could lead to greater participation and
more competitive pricing. To provide an open market, we introduce MODiCuM, a
decentralized system for outsourcing computation. MODiCuM deters participants
from misbehaving-which is a key problem in decentralized systems-by resolving
disputes via dedicated mediators and by imposing enforceable fines. However,
unlike other decentralized outsourcing solutions, MODiCuM minimizes
computational overhead since it does not require global trust in mediation
results. We provide analytical results proving that MODiCuM can deter
misbehavior, and we evaluate the overhead of MODiCuM using experimental results
based on an implementation of our platform
Riley v. California and the Stickiness Principle
In Fourth Amendment decisions, different concepts, facts and assumptions about reality are often tethered together by vocabulary and fact, creating a âStickiness Principle.â In particular, form and function historically were considered indistinguishable, not as separate factors. For example, âcontainersâ carried things, âwatchesâ told time, and âphonesâ were used to make voice calls. Advancing technology, though, began to fracture this identity and the broader Stickiness Principle. In June 2014, Riley v. California and its companion case, United States v. Wurie, offered the Supreme Court an opportunity to begin untethering form and function and dismantling the Stickiness Principle. Riley presented the question of whether cell phone searches incident to a lawful arrest were constitutional. The Court, which had clung to pre-digital concepts such as physical trespass well into the twenty-first century, appeared ready to explore how technology is reshaping historically understood conceptions of privacy. From a broader perspective, the case offers an initial step in reconciling pre-digital rules based on outdated spatial conceptions of physical things with the changing realities of a technology driven world
