Title: Extending
Blockchains in Computing and Systems
Blockchainspresent a
newparadigm in distributed systems. Its model
considersasynchronous computing environments.
Blockchainssupport distributed transactions with aims to
achieve reliability, near real-time response, immutability and
consensus. In most cases, these goals are same asthose of
Distributed Systems. Adoption of the notion of
blockchainsenhances distributed system capabilities for fully
decentralized, secure and scalable support. Itaddsto
operational costs. At the same time, itwill add to refinements
in middleware techniques. Further research must, focus on
cases of un-deterministic delays prior to commit (item joining
blockchain). It may further contribute modifications in
middleware, to achievemore deterministic form of delays, with
improvements in response times.
For many applications, blockchainsfacilitate secure,
independent consistent global states to distributedprocesses
(independently) at high-speed (near real-time response). In
case of recovery (aftera failure), nodes may attain the
potential to recover quickly and autonomously.
Distributed computing applications in healthcare,
transportation and e-commerce are likely to adopt blockchains
to enhance utilities and services.
