Columbia CryptoEconomics (CCE) Workshop 2025 | Day 2

8:30 AM - 7:00 PM
In-Person

The Forum at Columbia University - 605 W 125th Street, New York, NY

Wednesday, December 10 - Thursday, December 11


Economics and incentives are a critical part of the design of modern layer-1 blockchain protocols such as Ethereum. For example, scarce resources like blockspace require careful pricing. Block rewards, transaction fees, and maximal extracted value (MEV) must be shared across the stakeholders in the system, and participants must be incentivized appropriately. Subtle game theory governs the interactions between block builders, block proposers, and end users. Many of these economic and game-theoretic challenges are specific to the blockchain application domain, necessitating new models, new mechanisms, and new analysis frameworks.

This two-day workshop will bring together practitioners, researchers, and academics to discuss challenges, recent progress, and opportunities in the economics of blockchain protocols. The workshop will consist of invited keynote presentations, contributed talks, and panel discussions.
