From 60M to 200M: simulating Glamsterdam's fee market
Ethereum researchers simulated Glamsterdam's proposed gas limit increase from 60M to 200M across 12 demand scenarios, replaying 21 days of mainnet transactions through an instrumented reth fork with 50 simulation paths per scenario. After a 10-hour adjustment period, nine of twelve scenarios settled near 50% block utilization, with median base fees ranging from under 0.0001 gwei to 0.39 gwei depending on demand level and price elasticity. Three low-demand scenarios failed to reach the 100M-gas utilization threshold even at near-zero base fees, shifting gas costs to priority tips at a median of 0.025 gwei. At 2x demand, base fees varied 18-fold across elasticity assumptions (0.006 to 0.106 gwei), indicating block utilization alone cannot predict post-upgrade fee outcomes.
