Play-to-Earn (P2E) is a gaming model where players can earn real-world value, typically in the form of cryptocurrency tokens or NFTs, through in-game activities. Unlike traditional games where in-game assets belong to the developer, P2E games use blockchain technology to give players verifiable ownership of their digital items, which can be traded or sold on open markets. The model gained mainstream attention with games like Axie Infinity in 2021.
