This is an Open Access and Open Peer Review community at the vanguard of spreading and disseminating scientific knowledge and impactful discoveries to academics, professionals, researchers, and citizens worldwide. The aim of this community is to publish research about blockchain and blockchain-related discoveries managed by an Editorial Board of international professionals specialized in this technology. Blockchain and distributed-ledger technologies (DLT) allow the building of new infrastructures that enable open and trustworthy decentralized environments. Blockchain networks exist in a state of continuous consensus and automatic consistency checks enabling new trustworthy ways of communicating and transferring value with tremendous implications into our society. Join our community, and start reading, commenting, publishing, and collaborating with other researchers and decentralized technologies advocates.
Blockchain technology must have sparked widespread interest, applications associated with data monitoring, banking sectors, computer security, the Internet of Things, and food chemistry to the healthcare sector and cognitive science. The use of multimedia in the healthcare architecture also allows for the storage, processing and transmission of patient information in...
The maturity of the financial sector is pushing institutional centralization to the
extreme. The irruption of Blockchain technology seems to be celebrated as a way to
evade the barriers and asymmetry of a system increasingly biased. Decentralized
Finance has inaugurated a new stage where capital trading has a whole new meaning.
Not only has...
What do we really know about Blockchain? Talking about the Bitcoin revolution
without really knowing what is happening behind this innovation is common. Truth is
that we cannot separate the financial phenomenon from the technology that supports
it. Ethereum is the network that has given birth to the well-renowned system of
Decentralized Finance. The...
In the period that has passed, many projects in the form of proof of concept have been developped, and the most famous blockchain like Bitcoin and Etherium are old enough to start thinking about industrial projects and research trends in a more mature approach. This document aims to ask questions...
Les technologies blockchain combinent des innovations à des solutions informatiques existantes sur des systèmes informatiques distribués. Elles modifient de façon décisive la façon dont les organisations, même concurrentes, émettent et transfèrent en confiance des données ou des actifs numériques1 , sans passer par
une structure centrale de contrôle.
Il peut sembler paradoxal...
This document describes the computational models associated with blockchain and, in a second step, what is for blockchain the shutdown
problem. He then asks questions about the link between shutdown problem, computation, and governability in a blockchain project. This document aims to contribute to the implementation of industrial good practices. At...
This paper discusses several areas in the real estate and mortgage industries that a blockchain could be applied to and grow from. Blockchain is a distributed ledger technology that contains a ledger recording transactions hosted on the platform of tokenized assets, which smart contracts govern using transaction protocols. After interviewing...
For blockchain governance, data is an asset, and the time parameter is strategic and sensitive. This document aims to explore this issue for blockchain. It analyses the issues related to two properties associated with the parameter time : the ability to measure time (timestamp), and the guarantee of the ordering...
