Abstract
An adjustment in the Ethereum calldata cost which reduces the maximum possible block size and allows a higher block gas limit.
Motivation
Larger blocks take longer to propagate through the network. In this way, the maximum potential block size is constraining the block gas limit. Therefore, in order to safely increase the block gas limit, the calldata gas must be increased.
Specification
- Increase
G_CALLDATAZEROfrom 4 to 12. - Increase
G_CALLDATANONZEROfrom 16 to 48.
Rationale
Tripling the gas cost of calldata reduces the maximum possible block size by a factor of three.
Backwards Compatibility
Activation can cause some transactions to revert due to the increased gas costs.
Ahead of activation, eth_estimateGas could be calculated using the new parameters in order to provide results viable for activation, avoiding out-of-gas reverts.
Security Considerations
No security issues have been found.
