Motivated by the recent explosion of interest around blockchains, we examine whether they
make a good fit for the Internet of Things (IoT) sector. Blockchains allow us to have a
distributed peer-to-peer network where non-trusting members can interact with each other …

Long before the advent of the blockchain, digital cash had been conceptualized in a setting
with a central server trusted to prevent double spending (Chaum, 1983). 1 In spite of major
cryptographic advances, failure to ensure compatibility between centralization, anonymity …

In this chapter we provide an overview of the concept of blockchain technology and its
potential to disrupt the world of banking through facilitating global money remittance, smart
contracts, automated banking ledgers and digital assets. In this regard, we first provide a …

Overview. A blockchain is best understood in the model of state-machine replication [8],
where a service maintains some state and clients invoke operations that transform the state
and generate outputs. A blockchain emulates a “trusted” computing service through a …

A peer-to-peer network, enabling different parties to jointly store and run computations on
data while keeping the data completely private. Enigma's computational model is based on
a highly optimized version of secure multi-party computation, guaranteed by a verifiable …

This paper reports the outcome of a series of interviews and focus group meetings with
professionals working in post-trade processing and the provision of mutual distributed
ledger services. The objective was to elicit and document views on three research …

A blockchain is a distributed ledger for recording transactions, maintained by many nodes
without central authority through a distributed cryptographic protocol. All nodes validate the
information to be appended to the blockchain, and a consensus protocol ensures that the …

Blockchain technology and distributed ledgers are attracting massive attention and trigger
multiple projects in different industries. However, the financial industry is seen as a primary
user of the blockchain concept. This is not only due to the fact that the most well-known …

Service replication distributes an application over many processes for tolerating faults,
attacks, and misbehavior among a subset of the processes. The established state-machine
replication paradigm inherently requires the application to be deterministic. This paper …

Abstract—Recent interest about the blockchain technology brought questions about its application
to other systems than the cryptocurrency one. In this paper we present blockchain and discuss
key applications to network systems in the literature. I. INTRODUCTION Blockchain is a technology …
