The core of many cryptocurrencies is the decentralised validation network operating on
proof-of-work technology. In these systems, validation is done by so-called miners who can …

This paper presents a study of the Poof-of-Stake (PoW) Ethereum consensus protocol,
following the recent switch from Proof-of-Work (PoS) to Proof-of-Stake within Merge …

Many variants of (delegated) Proof-of-Stake blockchains have been introduced since 2016,
among which Cardano, Algorand, and Tezos have been more widely adopted. Each of …

We consider the “block withholding attack” as introduced by Eyal, where mining pools may
infiltrate others to decrease their revenues. However, when two mining pools attack each …

Adaptive networks today rely on overparameterized fixed topologies that cannot break
through the statistical conflicts they encounter in the data they are exposed to, and are prone …

In this paper, we study consensus behavior based on the local application of the majority
consensus algorithm (a generalization of the majority rule) over four-connected bi …

Forks in the Bitcoin network result from the natural competition in the blockchain's Proof-of-
Work consensus protocol. Their frequency is a critical indicator for the efficiency of a …

In this paper we describe a prototype of a blockchain-in-a-box system which allows users to
easily bootstrap the whole Ethereum Proof-of-Work (PoW) network running on multiple …

A common problem facing an organisation of autonomous agents is to track the dynamic
value of a signal, by aggregating their individual (and possibly inaccurate or biased) …

The analysis of time-varying interactions within multivariate systems has seen a great deal of
interest within the last decade, with the international oil market being an archetypal and …
