Public blockchains are becoming a ubiquitous network service. However, it's hard to make consensus-breaking changes to production blockchain networks. To overcome this, we created Virtualchain, a logical layer for implementing arbitrary fork*-consistent replicated state machines (RSMs) on top of already-running blockchains. Blockchains provide a totally-ordered, tamper-resistant journal of stat...

We present an interpretation of classical linear logic in terms of operations on the blockchain. Anyone who understands the current economic, sociological , and technological situation is likely to be very excited by what the blockchain technology promises. Anyone who has actually had to work with the blockchain in real situations with mission-critical exchanges on the line is very likely to be...

The goal of this research paper is to summarise the literature on implementation of the Blockchain and similar digital ledger techniques in various other domains beyond its application to crypto-currency and to draw appropriate conclusions. Blockchain being relatively a new technology, a representative sample of research is presented, spanning over the last ten years, starting from the early wo...

Since the inception of the Bitcoin technology, its underlying data structure–the blockchain–has garnered much attention due to properties such as decentralization, transparency, and immutability. These properties make blockchains suitable for apps that require disintermediation through trustless exchange, consistent and incorruptible transaction records, and operational models beyond cryptocurr...

Until now, most systems for Internet of Things (IoT) management, have been designed in a Cloud-centric manner, getting benefits from the unified platform that the Cloud offers. However, a Cloud-centric infrastructure mainly achieves static sensor and data streaming systems, which do not support the direct configuration management of IoT components. To address this issue, a virtualization of IoT...

Blockchain technology, while still challenged with key limitations, is a transformative Information and Communications Technology (ICT) that has changed our notion of trust. Improved efficiencies for agricultural sustainable development has been demonstrated when ICT-enabled farms have access to knowledge banks and other digital resources. UN FAO-recommended ICT e-agricultural infrastructure co...

This article suggests that the worldwide relevance of blockchain technology is motivated by the changes that it is expected to cause in: (i) the way that business is organised and (ii) regulated, as well as (iii) by the way that it changes the role of individuals within a society. The article presents an overview of the features of blockchain technology. It then takes a closer look into the dev...
