Blockchains are tamper evident and tamper resistant digital ledgers
implemented in a distributed fashion (i.e., without a central repository) and
usually without a central authority (i.e., a bank, com
Bitcoin's success has led to significant interest in its underlying
components, particularly Blockchain technology. Over 10 years after Bitcoin's
initial release, the community still suffers from a la
This chapter describes the primary building blocks of blockchain technology and illustrates various use-case scenarios of blockchain technology in the fields ofagriculture, energy health and others.
Supply chain applications operate in a multi-stakeholder setting, demanding
trust, provenance, and transparency. Blockchain technology provides mechanisms
to establish a decentralized infrastructure i
Homomorphic encryption and blockchain technology are regarded as two
significant technologies for improving e-voting systems. In this paper, we
suggest a novel e-voting system using homomorphic encryp
Blockchain technology is facing critical issues of scalability, efficiency
and sustainability. These problems are necessary to solve if blockchain is to
become a technology that can be used responsibl
We show that the efficiency and scalability of blockchain technology can be improved in the near-term without requiring powerful quantum computers to be available.
The rise of blockchain technology within a few years has attracted
researchers across the world. The prime reason for worldwide attention is
undoubtedly due to its feature of immutability along with t
We have entered an era where the importance of decentralized solutions has
become more obvious. Blockchain technology and its derivatives are distributed
ledger technologies that keep the registry of
We discuss the status quo of the power consumption of various implementations of blockchain technology, with special emphasis on the recent'bitcoin halving'and so-called'zk-rollups.
We argue that although bitcoin and other proof-of-work blockchains do indeed consume a lot of power, alternative blockchain solutions with significantly lower power consumption are already available today, and new promising concepts are being tested that could further reduce in particular the power consumption of large blockchain networksin the near future.
Blockchain is a decentralized ledger used to securely exchange digital
currency, perform deals and transactions efficient manner, each user of the
network has access to the least copy of the encrypted
Blockchain technology is an interlinked systematic chain of blocks that
contains transaction history and other user data. It works under the principle
of decentralized distributed digital ledger. This
In this paper, we systematically explore the attack surface of the Blockchain
technology, with an emphasis on public Blockchains. Towards this goal, we
attribute attack viability in the attack surface
Blockchains are still perceived chiefly as a new technology. But each
blockchain is also a community and a social experiment, built around social
consensus. Here I discuss three examples showing how c
This article considered deficiencies of the flourishing blockchain technology
manifested by the development of quantum computation. We show that the future
blockchain technology would under constant t
In this paper we want to emphasize the potential of blockchain technology in multiple sectors as well as the need to really understand the underlying principles which are allowing disruptability of traditional centralized software solutions.
Therefore, we implemented an educationallearning platform powered by blockchain technology to examine feasibility in industry and academic environment.
Blockchain has received a widespread attention because of its decentralized,
tamper-proof, and transparent nature. Blockchain works over the principle of
distributed, secured, and shared ledger, which
We delineate play-to-earn projects in terms of economic & governance models and implementation and analyze how blockchain technology can benefit these projects by providing system robustness, transparency, composability, and decentralized governance.
We also classify the implementation of the play-to-earn projects with different levels of robustness and transparency.
In this work, the importance of blockchain is analyzed and it is observed that blockchain technology and the processes associated with it will be utilised in the healthcare systems of the future for data acquisition from sensors, automatic patient monitoring, and secure data storage.
Quantum blockchain is another tool that can be utilised to maintain the confidentiality, authenticity, and accessibility of datarecords.
Blockchain technology has rapidly evolved from an enabling technology for
cryptocurrencies to a potential solution to a wider range of problems found in
data-centric and distributed systems. Interest
