Blueprint
What the dashboard will show.
The dashboard as it will open in Vantage. Each figure is named here and arrives with its receipt; until its data is published, its place stays empty.
Now
The current limit, the votes of recent blocks and how full they are.
Blocks voting up
%Share of the last day's blocks whose limit rose from their parent's.
Limit being converged on
gasThe limit that recent proposers hold steady at, the target the network is moving toward.
Block fullness
%Average gas used as a share of the gas limit over the last day's blocks.
Gas limit, recent blocks
gasThe gas limit of every block over the selected period, with the share of blocks voting up drawn beneath it.
Votes by builder
Recent blocks grouped by builder, where extra data or the fee recipient identifies one, with how many voted up, down or unchanged.
History
The gas limit since the Merge and every level it settled at.
Last new level
The date and block at which the limit last settled at a new level.
Days at this level
daysDays the network has spent at the current gas limit since it settled there.
Gas used against the limit
gasDaily gas used and gas limit since the Merge, to see whether demand fills new capacity.
Every settled level since the Merge
Each level the limit settled at since the Merge, with the date it was reached, how long the climb took and its first and last blocks.
- Period
- Last day, week or month, or since the Merge
About
What it answers, and for whom.
The gas limit caps how much computation fits in one Ethereum block, and with it how many transactions the chain can carry. Validators set it together: each block's proposer may move the limit a small step up or down from its parent's, toward the target set in its client, or registered with relays when an outside builder makes the block. This dashboard reads the limit from every block and shows which way proposers are pushing.
Use it to follow a gas limit increase as it happens: the share of recent blocks voting up, the limit the network is converging on and how full blocks are at the new level. A higher limit adds capacity, but every node must process the larger blocks, which is why increases come in steps, after testing.
Method
How it will be measured.
Every figure will be read at a block, kept with its source and its exact read, and open a receipt anyone can re-check.
How receipts work →- The gas limit and gas used are read from every block header, and each block's vote is the direction its limit moved from its parent's: up, down or unchanged.
- The protocol lets each block move the limit by just under a tenth of a percent of its parent's limit, so the share of blocks voting up sets how quickly the limit can rise.
- Votes are attributed to validators through the beacon proposer index of each slot, and to builders through the block's fee recipient and extra data, where known.
- A target is inferred where recent blocks stop moving: proposers that hold the limit steady have reached the target they are configured for.
- Each figure is pinned to its block, with the header read as its receipt.

Questions
Questions people ask.
What is the Ethereum gas limit?
It is the most gas a single block may use. A larger limit fits more transactions per block, raising capacity without changing the block time. The base fee targets half of the limit, so blocks average about half full when the fee is stable.
How is the gas limit increased?
No fork is needed. Each proposer may raise or lower the limit by a small step from the previous block, toward a target set in its client or passed to its builder. When enough validators configure a higher target, the limit climbs block by block until it reaches it.
Who decides the gas limit?
Validators do, through the targets they configure. In practice client teams set defaults and validators adopt them, so increases follow testing by client teams and researchers who check that nodes can keep up with larger blocks.
Is there a limit on gas per transaction?
Yes, since Fusaka. EIP-7825 caps the gas a single transaction may use, separately from the block limit, so one transaction cannot fill a whole block as the limit grows.
What happens to fees when the gas limit rises?
More gas per block means more room before blocks pass the half-full target that raises the base fee. If demand stays the same, the base fee tends to fall; if demand grows into the new space, fees settle near where they were. The dashboard shows fullness beside the limit to tell the two apart.
- Gas limit
- The most gas a block may use, set by proposers within a small step of the parent block's limit.
- Gas target
- Half the gas limit. Above it the next base fee rises; below it the base fee falls.
- Extra data
- A short free-form field in each block header that builders and clients often use to sign their name.
