In permissioned blockchains, a set of identifiable miners validates transactions and creates
new blocks. In scholarship, the proposed solution for the consensus protocol is usually …

Incentivized blockchain-based online social media (BOSM), where creators and curators of
popular content are paid in cryptocurrency, have recently emerged. Traditional social media …

This paper investigates the issue of fairness in Distributed Ledger Technology (DLT),
specifically focusing on the shortcomings observed in current blockchain systems due to …

A distributed and reliable source of randomness is always a critical element in cryptography,
both in the construction and application of cryptographic primitives. Modern cryptography …

This paper studies the relationship between blockchain patents and firms' environmental
and social performance. Using data from USPTO, we assess the effect of these patents on …

This paper considers the classical state machine replication (SMR) problem in a distributed
system model inspired by cross-chain exchanges. We propose a novel SMR protocol …

In recent years, blockchain technology has emerged as a pivotal tool for implementing
distributed ledgers. This thesis provides an in-depth exploration of blockchains that rely on …

Existing standards for player characterisation in tokenised state machine replication
protocols depend on honest players who will always follow the protocol, regardless of …

Blockchains based on proof-of-work suffer from serious drawbacks, such as high
computational overhead, long confirmation time, and forks. Committee-based blockchains …

Many blockchain platforms use committee-based consensus for scalability, finality, and
security. In this consensus scheme, a committee decides which blocks get appended to the …
