ETH Is Testing A 200M Gas Limit - But Not On Mainnet Yet Ethereum’s next big capacity experiment just cleared an important rehearsal. The upcoming Glamsterdam upgrade has successfully tested blocks at a 200 million gas limit, roughly double the kind of range Ethereum has been operating around recently. The point isn’t simply “more transactions per block.” $ETH developers are testing whether the network can process much heavier blocks without making validation unstable. One of the bigger changes is block-level access lists. Instead of execution staying mostly sequential, transactions can declare which parts of Ethereum’s state they need to touch, making more parallel processing possible. Nethermind says its client completed all 2,302 performance tests for the new setup. That matters because Ethereum’s scaling story has mostly been about pushing activity onto L2s. Glamsterdam is a different kind of scaling: increasing what the base layer itself can safely handle. The 200M setting is still experimental and isn’t currently scheduled to go straight onto mainnet. A proposed Sepolia test is set for October 6 first. So the interesting number here isn’t 200M by itself. It’s how far Ethereum can raise its execution ceiling before validator hardware becomes the bottleneck. #ETHBlockchain #ETHFoundation
