Ethereum’s Glamsterdam Devnet 8 started with 84,000 genesis validators and a built-in schedule to test a 200 million gas limit, putting the planned upgrade’s capacity changes onto a live developer network after core developers completed the related repricing work.
The configuration from Ethereum infrastructure group EthPandaOps sets genesis at Aug. 13, 12:00 UTC. It begins the network at a 60 million gas limit, schedules the Gloas consensus changes for epoch 1,536, and schedules 200 million gas for epoch 1,566. The file places the latter milestone at Aug. 20, 11:02 UTC.
The numbers make Devnet 8 a substantive test environment, not a mainnet switch. Ethereum’s public roadmap describes Glamsterdam as a planned H2 2026 upgrade, while its timing and final production configuration still depend on further client and test-network work.
ETH traded near $1,878 on Saturday, according to Kraken’s Ethereum price page. The token traded around $1,890 a month earlier and ranged between about $1,841 and $1,952 in the intervening observations. Those market moves do not establish that the testnet caused a price change.
The Devnet 8 deployment file explicitly exports NUMBER_OF_VALIDATORS=84000, a GAS_LIMIT_SCHEDULE that moves from 60 million to 200 million gas, and the dates and epochs for the experiment. That is a primary configuration record, not an estimate from a tracker.

ETHEthereum Devnet 8 Tests 84,000 Validators
The 84,000 count refers to validators created for this test network, not Ethereum mainnet’s validator set or a fresh commitment of 84,000 real validator operators. The configuration says that, at 32 ETH each, the testnet starts with 2.69 million ETH of simulated stake and uses compounding withdrawal credentials.
That scale is useful for testing mechanics that are hard to assess in a small local network. Client teams can test how execution and consensus software behave under a large validator population, while block builders, staking services and application developers can test their own infrastructure against a shared configuration.
The network’s consensus file assigns GLOAS_FORK_EPOCH to 1,536. The matching Devnet 8 consensus configuration also records 84,000 as its minimum active validator count and gives the network an Aug. 13 genesis time.
Gloas is the consensus-side half of the combined Glamsterdam name. Ethereum’s roadmap says the upgrade’s headline feature is enshrined proposer-builder separation, or ePBS, which moves parts of block-building coordination into the protocol. Testing it alongside a large validator set can expose client interoperability and operational issues before users face a mainnet fork.
The Devnet 8 start is a clear next step from the gas-pricing decision reported Friday. In that 200 million gas-limit sign-off, execution developers said their final values for the connected repricing work could safely support the higher limit. The devnet now supplies a live schedule for exercising that claim under a specific network configuration.
200M Gas Test Follows Gloas Activation
Gas is Ethereum’s unit for measuring the work performed in a block. A higher limit permits more total computation and data activity, but it can also put greater pressure on the computers that validate the chain if resource-intensive operations are priced too cheaply.
Devnet 8 starts at 60 million gas. Its configuration then schedules Gloas at epoch 1,536 and a 200 million gas limit at epoch 1,566, only 30 epochs later. The schedule makes the test sequence concrete, but it does not announce an identical final setting for Ethereum mainnet.
Ethereum.org says Glamsterdam’s scaling work includes more accurate pricing for persistent state creation and state access. The roadmap describes 200 million gas as a floor enabled by the upgrade’s new designs, while noting that developers were using a 150 million reference block limit to derive state pricing. The Devnet 8 schedule is therefore a test parameter in a broader engineering process, not evidence that all capacity questions are closed.
The structure also gives readers a useful distinction between available block capacity and the fee on a single transaction. A 200 million total limit would not automatically make every transfer proportionately cheaper. Individual costs continue to depend on the gas schedule, transaction type and network demand, and repricing can raise the cost of operations that create lasting state.
It is separate from Ethereum’s longer-range goal of increasing layer-1 throughput. The Lean Ethereum roadmap discussed an aspirational 10,000-transactions-per-second direction. Devnet 8 is a bounded test of named upgrade components, not confirmation of that outcome.
Glamsterdam Mainnet Date Remains Unset
The central constraint is unchanged: a started devnet is not a mainnet activation. The EthPandaOps repository labels Devnet 8 as work in progress, and the materials reviewed do not state a public Glamsterdam mainnet date, an exchange or wallet migration requirement, or a change to ordinary ETH balances.
Ethereum’s roadmap says the upgrade is intended to improve capacity while keeping the burden on node operators manageable. It lists other elements that will need validation, including block-level access lists, proposal-builder separation and gas-pricing changes for state operations. Each client implementation must still converge on the final specifications.
The design’s safety focus also separates this work from the quantum-resistance discussion Ethereum has been developing. Ethereum’s quantum-safe key registry concerns a future account-security path, whereas Devnet 8 is testing planned execution and consensus changes for Glamsterdam.
The Crypto Fear & Greed Index read 34, or Fear, on Aug. 15, up from 29 the day before. That sentiment indicator is broad market context, not a measure of Devnet 8’s health or evidence that the engineering schedule is affecting ETH.
Fear & Greed Index
Aug. 15, 2026The next useful milestones are the Gloas activation and 200 million gas test scheduled in Devnet 8, followed by client results, broader public test work and a mainnet schedule. Until those steps occur, the verified change is narrower: Ethereum now has an 84,000-validator live development network configured to test the capacity target, while mainnet timing remains undisclosed.

Frequently Asked Questions
What is Ethereum Glamsterdam Devnet 8?
Glamsterdam Devnet 8 is a live developer test network for Ethereum's planned Glamsterdam upgrade. Its public configuration schedules the upgrade's Gloas changes and a 200 million gas-limit test before any mainnet activation.
Does Devnet 8 raise Ethereum's mainnet gas limit to 200 million?
No. The 200 million figure is scheduled only in the Devnet 8 configuration. Ethereum mainnet's live gas limit does not change because a developer testnet starts.
Why does the 84,000-validator count matter?
A large genesis validator set gives client teams and infrastructure operators a more demanding environment to test consensus behavior, block building and operational tooling before a mainnet rollout. It is not a count of mainnet validators.
When will Glamsterdam reach Ethereum mainnet?
No mainnet date is set in the Devnet 8 materials reviewed for this report. Ethereum still needs cross-client testing, releases, public testnet work and a coordinated mainnet schedule.
