Cryptoeconomics is an evolving economic paradigm for a cross-disciplinary approach to the study of digital economies and decentralized finance (DeFi) applications. [1] [2] Cryptoeconomics integrates concepts and principles from traditional economics, cryptography, computer science, and game theory disciplines. [3] Just as traditional economics provides a theoretical foundation for traditional financial (a.k.a., Centralized Finance or CeFi) services, cryptoeconomics provides a theoretical foundation for DeFi services bought and sold via fiat cryptocurrencies, and executed by smart contracts.
The term cryptoeconomics was coined by the Ethereum community during its formative years (2014-2015), [4] but was initially inspired by the application of economic incentives in the original Bitcoin protocol in 2008. [5] Although the phrase is typically attributed to Vitalik Buterin, the earliest public documented usage is a 2015 talk by Vlad Zamfir entitled “What is Cryptoeconomics?” [6] Zamfir describes the field as “… a formal discipline that studies protocols that govern the production, distribution, and consumption of goods and services in a decentralized digital economy. Cryptoeconomics is a practical science that focuses on the design and characterization of these protocols”.
In a 2017 talk, Buterin called cryptoeconomics as “building systems that have certain desired properties. Use cryptography to prove property about messages that happened in the past. Use economic incentives defined inside the system to encourage desired properties to hold into the future." [7]
Cryptoeconomics may be considered an evolution of digital economics, which in turn evolved from traditional economics (commonly divided into microeconomics and macroeconomics). In a 2024 survey, Kensuke Ito framed the goals of the field as designing consensus-building for decentralization and designing token value for autonomy, [8] calling for a close integration of cryptoeconomics with the overlapping field of tokenomics.
a) Designing consensus for decentralization: In blockchain systems, decentralization relies on consensus-building rather than centralized authority. These systems gather and aggregate information from distributed peers and produce a shared outcome (Consensus). This requires special mechanisms to handle issues like dishonest, strategic behavior or fake identities (Sybil attacks).
b) Designing token value for autonomy: In blockchain systems, agents act to maximize expected rewards. When those rewards are paid in tokens, the token’s value becomes crucial for ensuring the incentives actually work. This requires supporting market stability on both the supply and demand side, such as price-pegging schemes, automated market makers (AMMs), and models that account for marginal cost and marginal utility.
The historical roots of cryptoeconomics can be traced to the rise of altcoins, prominent among them the Ethereum project, which in 2015 pioneered the integration of smart contracts into its blockchain, thereby enabling a wide range of DeFi applications. [9]
Similar to how traditional economics is divided into macroeconomics (regional, national, and international economics) and microeconomics (individual and enterprise economics) subdisciplines, cryptoeconomics can be divided into crypto-macreconomics and crypto-microeconomics subdisciplines.
Crypto-macroeconomics is concerned with the regional, national, and international regulation of cryptocurrencies and DeFi transactions. More broadly, this subdiscipline analyzes the transmission of shocks and volatility between the emergent cryptocurrency markets and the traditional economy. [10] Research in this area investigates the growing integration of crypto assets with conventional assets, finding significant spillover effects where shocks in one market transmit to the other. [11] Recent studies using structural models show that cryptocurrency price shocks—driven by factors like market sentiment and technology— [12]
This growing economic significance has, in turn, prompted varied policy responses from governments around the world. The Group of Seven governments' interest in cryptocurrencies became evident in August 2014, when the United Kingdom Treasury commissioned a study of cryptocurrencies and their potential role in the UK economy, and issued its final report in January 2021. [13] In June 2021, El Salvador became the first country to accept Bitcoin as legal tender. [14] In August 2021, Cuba followed with a legal resolution to recognize and regulate cryptocurrencies such as Bitcoin. [15] However, in September 2021, the government of China, the single largest market for cryptocurrency, declared all cryptocurrency transactions illegal, completing a crackdown on cryptocurrency that had previously banned the operation of intermediaries and miners within China. [16]
Crypto-microeconomics is concerned with the individual and enterprise usages of cryptocurrencies and DeFi transactions. A strong majority of USA adults have heard about major cryptocurrencies (Bitcoin, Ether), and 16% say they personally have invested in, traded, or otherwise used one. [17] More than 300 million people use cryptocurrency worldwide, and approximately 46 million Americans have invested in Bitcoin. [18]
Bitcoin, along with other cryptocurrencies, has been described as an economic bubble by many economists, including Robert Shiller, [19] Joseph Stiglitz, [20] Vasilis Kostakis, [21] Richard Thaler, [22] Paul Krugman, [23] and Nouriel Roubini. [24] In addition, Bitcoin and other cryptocurrencies have been criticized for the amount of electricity required for cryptocurrency “mining” (blockchain transaction validation), [25] and for their being used to purchase illegal goods.
