Enterprise Readiness of Permissioned Blockchain

By Harika Narumanchi and Nitesh Emmadi, TCS Innovation Labs, India

Blockchain is an immutable shared ledger that enables mutually distrusting parties to transact with each other without any central authority. The parties together form a peer-to-peer network of nodes and enforce a common ledger. Blockchain is broadly categorized into permissioned and permissionless. In permissionless blockchain there are no restrictions on entities joining or leaving the network whereas in permissioned blockchain the entities are verified identities and the entities go through identity verification process before joining the network that enables non-repudiation and accountability. In this article, we focus on permissioned blockchains as they are more suitable in enterprise environments. Blockchain is being leveraged in supply chain, IoT, finance and several other business use cases. A survey by Wikibrands suggests that blockchain is one of the top 30 emerging technologies that will impact us the most over the next decade. A report by world economic forum predicted that 10% of global GDP would be stored on blockchain technology by 2025. Considering this importance of blockchain, we emphasize on the features and challenges involved in making permissioned blockchains deployable in practice.

The Essential Diversity of Blockchain Nodes

By Thomas Burke, CACI, International

The rampant evolution of blockchain technology has enraptured the world, and in many ways has caught everyone unprepared for what the future holds. The originating, unhindered cryptocurrency platform, with all its controversial and somewhat enigmatic trappings, often confounds those seeking to implement blockchain within corporate and government organizations – even at the most basic of levels.

Blinking: Trusted Digital Identity Solution

By Nikola Milinković; Miloš Milovanović; Miroslav Minović; Aleksei Migitko; and Andreja Velimirović, Blinking

The world is becoming increasingly digital. Digitalization and automatization of different aspects of our lives have grown to become the undisputed facts of this era. These two interlinked trends are forcing more and more people to communicate, exchange and conduct business online.

Nonetheless, there is not an established, reliable, and universal way of creating, handling and confirming digital identity of people in the online environment. At its most rudimentary level, an identity can be described as a set of personal characteristics which both define an individual and uniquely distinguish him or her from other people.

Open Execution—The Blockchain Model

By Khaled Salah, Khalifa University; Ernesto Damiani, Khalifa University; Ala Al-Fuqaha, Western Michigan University; Thomas Martin, Manchester Metropolitan University; Kamal Taha, Khalifa University; and M. Khurram Khan, King Saud University

In this article, we argue that blockchain has paved the way for an unprecedented, powerful phenomenon that is far superior to open source. We call this phenomenon “Open Execution.” As opposed to blackbox execution, open execution has the ability to verify, validate, and scrutinize the execution outcome, and thereby increasing the trust and credibility of execution. In this article, we discuss how blockchain is the right model and computing platform for open execution. We give a definition for open execution and describe a few use cases.
