A protocol rule that permanently removes tokens from circulation when they are used to pay for network services, reducing supply over time.
Helium's Data Credits (DC) system is a canonical example: to send data across the Helium network, operators burn HNT to mint DC at a fixed USD peg. More network usage → more HNT burned → deflationary pressure on supply. Burns partially offset emissions and are a key metric for assessing a DePIN token's long-term value accrual.
