Net Issuance
New units created over a period minus units destroyed, showing whether supply actually grew or shrank.
Net issuance exists because gross issuance alone overstates supply growth on any network with a burn mechanism. On Ethereum the comparison is between issuance paid to validators under proof-of-stake and the base fee destroyed by the EIP-1559 fee mechanism introduced in 2021; when demand for block space is high enough, burns exceed issuance and supply falls over that period. The figure is period-dependent and activity-dependent by construction, so a week of heavy usage and a quiet week can point in opposite directions. It is normally shown as units per period or annualized as a percentage of supply.
In practice
After Ethereum's 2022 transition to proof-of-stake, staking issuance and the EIP-1559 base-fee burn are netted over a period to give a single supply change figure that can be positive or negative.
The common misunderstanding
A period of negative net issuance is not a permanent property of an asset; it depends on network activity and reverses when demand for block space falls.
The figure this maps to
New tokens created each day minus tokens destroyed, so supply growth after burns.
Limits: It is the small difference between two large numbers measured under different conventions, so it carries the error of both series and can change sign because of a definitional choice rather than a real event. A single 30-day window is short enough that seasonal patterns in blockspace demand…
