🚨 Ethereum Just Changed How Blocks Get Built
$ETH Glamsterdam is now live on the Sepolia testnet, marking a major step toward changing Ethereum’s block-production architecture.
The headline isn’t simply “more transactions.”
It’s who controls the block-building process.
🔹 Before: third-party builders assembled blocks while validators mainly proposed/attested to the result.
🔹 With Glamsterdam: Enshrined Proposer-Builder Separation (ePBS) moves the proposer-builder relationship into Ethereum’s protocol itself. The protocol now defines how builders commit, reveal payloads, and get paid.
And there’s more:
⚡ Sepolia is testing a 200M gas limit, up from roughly 60M — more than 3× the previous level.
🧩 Block-Level Access Lists (BALs) are also being introduced, allowing clients to identify state touched by a block and opening the door to more parallel processing and higher execution capacity.
📌 Important distinction:
The 200M gas figure is a testnet capacity target, not proof that Ethereum suddenly became 3× faster.
The real objective is to determine how much additional workload validators can safely handle while keeping the network decentralized and practical to operate.
Ethereum has also adjusted state-access and state-creation gas costs to better reflect real computational resources and make future gas-limit increases safer.
🔥 The bigger catalyst comes next: MAINNET.
Sepolia is the rehearsal. Hoodi and Ethereum mainnet still have no finalized activation date.
For $ETH, the important signal isn’t just today’s testnet headline.
It’s whether Glamsterdam successfully proves that Ethereum can push higher capacity + protocol-level block building + more efficient validation without compromising decentralization.
Testnet is the experiment.
Mainnet is the real market signal.
