What is Cryptoeconomics?

Could you elaborate on the concept of Cryptoeconomics? I'm interested in understanding how it marries the principles of cryptography and economics. What are the CORE tenets that define this field? How do they intersect to create a unique framework for understanding and analyzing decentralized systems, particularly in the realm of cryptocurrencies? I'd appreciate any insights you could provide on the economic incentives, security mechanisms, and potential applications of Cryptoeconomics in today's digital landscape.
