Cryptoeconomics

Cryptoeconomics is an evolving economic paradigm for a cross-disciplinary approach to the study of digital economies and decentralized finance (DeFi) applications. Cryptoeconomics integrates concepts and principles from traditional economics, cryptography, computer science, and game theory disciplines. Just as traditional economics provides a theoretical foundation for traditional finan

Cryptojacking

Cryptojacking is the act of exploiting a computer to mine cryptocurrencies, often through websites, against the user's will or while the user is unaware. One notable piece of software used for cryptojacking was Coinhive, which was used in over two-thirds of cryptojacks before its March 2019 shutdown. The cryptocurrencies mined the most often are privacy coins—coins with hidden transactio

Equihash

Equihash is a memory-hard Proof-of-work algorithm introduced by the University of Luxembourg's Interdisciplinary Centre for Security, Reliability and Trust (SnT) at the 2016 Network and Distributed System Security Symposium. The algorithm is based on a generalization of the Birthday problem which finds colliding hash values. It has severe time-space trade-offs but concedes vulnerability

Financial cryptography

Financial cryptography is the use of cryptography in applications in which financial loss could result from subversion of the message system. Financial cryptography is distinguished from traditional cryptography in that for most of recorded history, cryptography has been used almost entirely for military and diplomatic purposes.

Networks

Transient-key cryptography

Transient-key cryptography is a form of public-key cryptography wherein keypairs are generated and assigned to brief intervals of time instead of to individuals or organizations, and the blocks of cryptographic data are chained through time. In a transient-key system, private keys are used briefly and then destroyed, which is why it is sometimes nicknamed “disposable crypto.” Data encryp
