Computer Science and Game Theory: A Brief Survey
There has been a remarkable increase in work at the interface of computer
science and game theory in the past decade. In this article I survey some of
the main themes of work in the area, with a focus on the work in computer
science. Given the length constraints, I make no attempt at being
comprehensive, especially since other surveys are also available, and a
comprehensive survey book will appear shortly.Comment: To appear; Palgrave Dictionary of Economic
From Blockchain to Hashgraph: Distributed Ledger Technologies in the Wild
With the introduction of the term blockchain in 2008, its interest has been
increasing in the community since the idea was coined. The reason for this
interest is because it provides anonymity, security and integrity without any
central third party organisation in control of data and transaction. It has
attracted huge interest in research areas due to its advances in various
platforms, limitations and challenges. There are various Distributed Ledger
Technologies that demonstrates their special features which overcome
limitations of other platforms. However, implementations of various distributed
ledger technologies differ substantially based on their data structures,
consensus protocol and fault tolerant among others. Due to these variations,
they have a quite different cost, performance, latency and security. In this
paper, working and in-depth comparison of major distributed ledger technologies
including their special features, strengths and weaknesses is presented and
discussed by identifying various criteria
