Ethereum’s core developers wrapped up a week-long interoperability sprint last Friday and walked away with one of the most consequential technical commitments the network has made in years: a hard floor of 200 million gas per block, locked in for the post-Glamsterdam era.
That number represents a near-tripling of the roughly 60 million gas limit the network runs today, and it has immediate implications for how much computation fits in each Ethereum block, how low mainnet fees can go, and whether the case for migrating to a Layer-2 rollup still holds the same weight it did twelve months ago.
What Happened at the Soldøgn Interop Sprint
Between April 28 and May 2, client teams from across the Ethereum system gathered for what the Ethereum Foundation called the “Soldøgn” interoperability sprint – a focused engineering session designed to align client implementations before Glamsterdam ships.
By Friday, three core goals had been met, according to a recap published on the Ethereum Foundation blog:
The 200M gas target isn’t just a validator preference – it’s being treated as a hard floor, meaning validators who try to signal a lower gas limit will be out of consensus.
Why 200M Gas Changes the Calculation
The jump from 60M to 200M isn’t a simple scaling tweak. Glamsterdam couples the gas limit increase with parallel transaction execution – the ability to process independent transactions simultaneously rather than sequentially.
BingX’s explainer on the upgrade notes that the combination of higher gas ceilings and parallel execution is projected to reduce L1 gas costs by up to 78% during periods of peak demand. Blockonomi reported on Saturday that fees “could stay near zero for years” if throughput scales ahead of demand.
For context, peak Ethereum fees during the 2021 NFT surge hit $50-$200 per transaction. Even during moderate DeFi activity in early 2026, users regularly paid $5-$15 for a swap. A 78% reduction would push that range firmly below $2, potentially into sub-$1 territory for standard transfers.
The Glamsterdam Upgrade: Key Technical Changes
Glamsterdam, scheduled for June 2026, bundles several EIPs:
The upgrade follows Pectra (May 2025) and represents Ethereum’s continued push to remain competitive on throughput without compromising decentralisation.
What This Means for Layer-2 Networks
The Layer-2 system had a complicated reaction to the news. L2 networks – Arbitrum, Optimism, Base, zkSync – have built their entire user proposition around cheaper, faster transactions compared to Ethereum mainnet.
A previous CoinDesk analysis noted that “Ethereum Layer-2 Consolidation Accelerates as Smaller Rollups Become Zombie Chains” – suggesting that even before Glamsterdam, the rollup landscape was thinning out. A 78% cut to L1 fees would accelerate that pressure.
However, L2 advocates argue that rollups offer, and application-specific customisation that will remain valuable regardless of L1 pricing.
The more detailed take: Glamsterdam doesn’t kill L2s. It kills the weakest L2s – the ones whose only offer was “cheaper than mainnet.”
Ethereum Price and Market Context
ETH was trading around $2,322 at the time of writing, up modestly on the Glamsterdam confirmation news. The network’s transition toward a deflationary supply model post-Merge, combined with a clear scaling plan, continues to attract institutional interest.
Ark Invest’s latest research notes Ethereum’s TVL recovery to $95 billion and calls the L1-L2 interaction a “maturing symbiosis rather than a zero-sum competition.”
Developer Reaction
The crypto developer community welcomed the 200M floor confirmation. Coin Bureau called it “Ethereum’s most significant technical step since the Merge,” while independent developers on X pointed out that the gas limit increase, combined with EIP-4844 blob availability from Dencun (March 2024), gives rollups both a cheaper base layer and more blob space – a compounding benefit.
Ethereum co-founder ik Buterin has publicly supported higher gas limits as part of the plan toward 10,000+ TPS on the base layer without fragmenting the user experience across chains.
FAQ
When does the Glamsterdam upgrade go live? Glamsterdam is currently scheduled for June 2026, pending final testnet coordination between client teams. The Soldøgn sprint confirmed alignment on the key parameters required for the upgrade.
Will Glamsterdam lower Ethereum transaction fees immediately? Not immediately – the full fee reduction depends on network usage staying below the expanded gas capacity. If activity grows faster than throughput, fees can still spike. But analysts project a sustained reduction in baseline fees of 60-78% under normal usage conditions.
Does Glamsterdam make Layer-2 networks obsolete? No. While cheaper L1 fees reduce the fee-arbitrage advantage of rollups, L2 networks still offer application customisation, isolated execution environments, and specialised sequencing. Smaller general-purpose rollups may struggle to compete, but purpose-built L2s are expected to survive and grow.
