Digital Twins and Agent-based Modeling and Simulation

Digital Twins Types There are presently three types of digital twins: those for individual assets, operations and predictions. In this article, we will focus on individual assets. Examples of these assets include drilling machines in the oil and gas industry or assembly line equipment.

Distributed Decision of Trust

Distributed Decision of Trust We live in an age where most, if not all of us use interconnected technological devices all day, everyday. The interconnectivity is sometimes established by trusted third party servers, and sometimes established in a completely peer-to-peer way thanks to the advanced technologies like bluetooth and wi-fi.

Adaptive State Trie Pruning in Blockchains

Bitcoin sürdürülebilir bir sistem mi?

Bitcoin ve blokzincirleri konusunda biraz mürekkep yalamış birisi olarak, son günlerde konuya olan büyük ilgiden dolayı bazı teknik konulara değinme ihtiyaci hissettim. İlk olarak, bu yazıda Bitcoin sisteminin neden sürdürülebilir olmadığını aktarmaya çalışacağım.

Is it possible to understand the dynamics of cryptocurrency markets over different time scales

Interested cryptocurrency users have already realized that sometimes the values graphs of cryptocurrencies look quite similar. For example, such a phenomenon has been noticed between Bitcoin, Ethereum and Litecoin and reported on StackExchange.

Is Bitcoin fair

In the classical Bitcoin protocol, the current maximum block size (1 MB) limits number of transactions per block (around 3 transactions per second). This can force regular users to compete for transactions by increasing the fees, pricing some users out of the network, once the corresponding blockchain system is popular enough, which is the case for Bitcoin currently.

Combining Privacy and Block-chain technology through Zero-Knowledge Proof

Context Blockchain technologies are suited to enact a large number of interactions among system users without the need of a central authority. Trust among users is built in a decentralized manner thanks to a distributed protocol permanently running among geographically distributed nodes.

Development of a Blockchain-based Digital Asset Exchange System

Context The management of the flow of assets (goods, physical components, digital data and assets, etc.) in a distributed and efficient manner while managing the trust between the organizations (suppliers, integrators, service providers, resellers, clients, customers, users, etc.
