## Abstract
|
||
|
|
|
||
|
|
Set an in-protocol cap for the gas limit of 30,000,000.
|
||
|
|
|
||
|
|
## Motivation
|
||
|
|
|
||
|
|
A high gas limit increases pressure on the network. In the benign case, it
|
||
|
|
increases the size of the state and history faster than we can sustain. In the
|
||
|
|
malicious case, it amplifies the devastation of certain denial-of-service
|
||
|
|
attacks.
|
||
|
|
|
||
|
|
## Specification
|
||
|
|
|
||
|
|
As of the fork block `N`, consider blocks with a `gas_limit` greater than
|
||
|
|
`30,000,000` invalid.
|
||
|
|
|
||
|
|
## Rationale
|
||
|
|
|
||
|
|
### Why Cap the Gas Limit
|
||
|
|
|
||
|
|
The gas limit is currently under the control of block proposers. They have the
|
||
|
|
ability to increase the gas limit to whatever value they desire. This allows
|
||
|
|
them to bypass the EIP and All Core Devs processes in protocol decisions that
|
||
|
|
may negatively affect the security and/or decentralization of the network.
|
||
|
|
|
||
|
|
### No Fixed Gas Limit
|
||
|
|
|
||
|
|
A valuable property of proposers choosing the gas limit is they can scale it
|
||
|
|
down quickly if the network becomes unstable or is undergoing certain types of
|
||
|
|
attacks. For this reason, we maintain their ability to lower the gas limit
|
||
|
|
_below_ 30,000,000.
