Cryptoeconomics is a field that combines cryptography and economics to create secure and decentralized systems. It uses cryptographic techniques to ensure the integrity and security of transactions, while economic principles help to incentivize participants to act honestly within a network. This is particularly important in systems like blockchain where trust is distributed among many users. In cryptoeconomic systems, participants are often rewarded for their contributions, such as validating transactions or maintaining the network. This creates a self-sustaining ecosystem where users are motivated to follow the rules, as their actions directly impact their financial rewards. Examples of cryptoeconomic systems include Bitcoin and Ethereum.
