EIP-7923 cuts 95% of memory-expansion gas on today's execution paths
· 6 min read
EIP-7923 sounded like a repricing for pathological memory users. Then I ran its 100-gas page charge over 34.08 million recent mainnet transactions, holding the historical execution paths fixed. On those paths, it nearly deletes the charge it replaces: no more than 0.52 billion gas instead of 10.35 billion.
That 95% headline is real and a little misleading. Memory expansion was only 0.340% of all transaction gas in the sample, so the minimum fixed-path saving is 0.323% of historical transaction gas. The first free 4 KiB page does most of the work.
