Cryptoeconomics brings together the fields of economics and computer science to study the decentralized marketplaces and applications that can be built by combining cryptography with economic incentives.

It focuses on individual decision-making and strategic interaction between different participants in a digital ecosystem (e.g. users, providers of key resources, application developers etc.), and uses methodologies from the field of economics - such as game theory, mechanism design and causal inference - to understand how to fund, design, develop, facilitate the operations and encourage the adoption of decentralized marketplaces and related services and digital assets. 

The resulting "digital economies" often require the definition of a monetary, fiscal, privacy and innovation policy. Moreover, they need effective governance to ensure that the platform maintainers can upgrade the underlying software protocols over time in response to changes in the environment, technology or market needs.
