On Curve Finance, the inflation is going to users who provide liquidity. This usage is measured with gauges. The liquidity gauge measures how much a user is providing in liquidity.
Each gauge also has a weight and a type. Those weights represent how much of the daily CRV inflation will be received by the liquidity gauge.
The weight systems allow the Curve DAO to dictate where the CRV inflation should go. You can vote at this address: https://dao.curve.fi/gaugeweight
By doing so, you can put your voting power towards the liquidity gauge (or pool) you think should receive the most CRV.
