Abstract
This proposal updates cost per state byte (CPSB), the unit gas cost per new state byte introduced in SIP-8037, by re-deriving it for a new reference block gas limit. All other parameters, mechanisms, and semantics defined in SIP-8037 are unaffected and remain unchanged.
This is a placeholder SIP. The new reference block gas limit, the re-derived CPSB value, and the accompanying rationale are still to be determined.
Motivation
SIP-8037 derives CPSB from a reference block gas limit of 150M gas units, noting that “if a future block gas limit increase materially changes the expected state growth rate, CPSB can be re-derived in a subsequent SIP.” As the block gas limit increases beyond that reference point, CPSB needs to be recalibrated to keep state growth on target.
Specification
TBD. The CPSB value below will be re-derived using the same methodology as SIP-8037, with the reference block gas limit updated to a value still to be determined.

Rationale
TBD
Backwards Compatibility
This SIP updates a parameter defined by SIP-8037 and inherits its backwards compatibility considerations.
Security Considerations
Needs discussion.
