Scope at the cutoff. At the information cutoff, this draft proposed a protocol-wide maximum declared transaction gasLimit of 30,000,000, independent of the block gas limit. A transaction above the cap would be excluded during transaction-pool validation, and a block containing one would be invalid before processing. The proposal did not change EVM gas prices or accounting, transaction encoding, opcodes, or block fields.

Under-specified at assessment cutoff: Yes
The EIP text available at the assessment cutoff left material behavior unresolved. The affected criteria and the plausible total range record that uncertainty.
Why: The central >30,000,000 block-validity predicate is testable as written, but the draft is not fully normative about fork activation, whether its broad wording covers every transaction form without exception, or whether references to gas usage are exclusively references to the declared gasLimit. Its proposed pool error code is only an example. These gaps are material to finalizing the test matrix but are localized and do not obscure the primary validity rule.
Plausible total
7–9
recorded score 8 · plausible tiers Low
Unresolved questions at the cutoff (4)
- What exact fork activation condition makes the new transaction and block rule effective?
- Does "any single transaction" cover every transaction form carrying a gasLimit, with no protocol-level exceptions?
- Are the abstract's references to maximum gas usage intended solely as checks of the sender-declared gasLimit, as the concrete validation clauses state?
- Is any exact transaction-pool error code normative, or is only rejection required?
Notable ambiguities noted by the assessor (3)
- The abstract describes a cap on gas usage, while the normative checks compare the declared gasLimit; the assessment follows the concrete gasLimit rule.
- The phrase "appropriate error code" is followed by an example rather than a required code, leaving transaction-pool error reporting non-normative.
- No explicit activation clause or exhaustive transaction-scope definition appears in the historical draft.
Criterion breakdown
| Criterion | Score | Why this score | Evidence / uncertainty |
|---|---|---|---|
| New or modified transaction validity mechanismsUnder-specified | 2 | This is a new validity rule for existing transactions: values above the cap are rejected at pool admission and make a containing block invalid. It changes affected existing cases but is a single comparison requiring limited vector updates rather than testing-infrastructure redesign. |
Confidence: High |
| Security risks | 2 | The consensus-critical cap touches the limited components of transaction admission and block acceptance. An inconsistent comparison or application could cause acceptance divergence, so targeted boundary review and fuzzing are warranted, while the rule has no broad interaction with EVM execution. |
Confidence: Medium Uncertainty: The EIP discusses intended DoS mitigation but does not analyze failure modes of inconsistent client enforcement. |
| Block syncing changesUnder-specified | 1 | Block import or syncing gains one simple validation rule: reject a block when any contained transaction declares a gasLimit above the cap. The check uses an existing transaction field and does not change its encoding. |
Confidence: Medium Uncertainty: The EIP calls this block validation rather than specifically RLP validation, so the rubric's block-RLP boundary admits a score of 0 interpretation. |
| Patterns affecting pre-existing tests | 1 | A minor subset of existing transaction and block-validity cases using gasLimit values above 30,000,000 changes from accepted to rejected. The EIP says values below the cap remain unaffected and expects only minimal practical impact. |
Confidence: Medium Uncertainty: The package contains no historical test inventory, so the exact number of pre-existing vectors above the cap is not established. |
| Edge/boundary conditions | 1 | The EIP introduces one sharp numeric boundary: 30,000,000 is permitted while a gasLimit greater than 30,000,000 is rejected, in both admission and block validation contexts. |
Confidence: High |
| Unspecified behavior requiring cross-client consensusUnder-specified | 1 | The concrete greater-than comparison determines the central block-consensus boundary, but the short draft leaves a few details implicit: whether every use of "gas usage" means declared gasLimit, the exhaustive transaction scope, and activation. These have an obvious intended reading rather than requiring a new consensus mechanism to be designed. |
Confidence: Medium Uncertainty: The suggested error code is explicitly only an example and appears to concern local admission rather than the block-consensus result; it is not treated as an additional consensus ambiguity. |
Show 22 zero-score criteria
| Criterion | Score | Why this score | Evidence / uncertainty |
|---|---|---|---|
| Added opcodes | 0 | No opcode is introduced. |
|
| Modified opcodes | 0 | Despite the heading, the described behavior changes only transaction and block validation; no pre-existing opcode result or behavior changes. |
|
| Added precompiles | 0 | No precompile is introduced. |
|
| Modified precompiles | 0 | No precompile logic or gas schedule is modified. |
|
| Added system contracts | 0 | The validation cap introduces no system contract. |
|
| Modified system contracts | 0 | The proposal neither modifies a system contract nor describes an indirect behavioral effect on one. |
|
| EVM Gas rule changes | 0 | The proposal adds a validity ceiling on the transaction's declared gasLimit; it does not alter an EVM gas charge, cost schedule, or accounting mechanism. |
|
| State-access ordering within opcode execution | 0 | The specified checks occur at transaction-pool and block validation and do not move any state access or gas charge within opcode execution. |
|
| Blob gas accounting changes | 0 | The cap concerns the ordinary transaction gasLimit and specifies no blob-gas accounting change. |
|
| State gas accounting changes | 0 | No state-writing charge, state-gas budget, reservoir, or spill interaction is introduced or modified. |
|
| New EVM gas refund | 0 | The proposal contains no gas-refund mechanism or refund-rule change. |
|
| New transaction types | 0 | The cap applies a validation rule to transactions and does not define a new transaction type. |
|
| New block / header fields | 0 | The existing block gas limit remains independent of the transaction cap, and no new block or header field is added. |
|
| Encoding changes (RLP/SSZ) | 0 | The proposal constrains the value of the existing gasLimit field but does not alter transaction, block, or interface encoding. |
|
| New fork activation mechanism | 0 | The proposal specifies no state or internal-variable modification at the fork activation block. |
Uncertainty: The historical draft does not state its activation mechanics, but nothing in its described rule calls for the kind of activation-block mutation scored by this anchor. |
| Engine API changes | 0 | No Engine API endpoint, field, or communication mechanism is specified. |
|
| Transition-tool interface changes | 0 | Validation uses the existing transaction gasLimit value and requires no new transition-tool field or interface mechanism. |
|
| New invariant on pre-existing tests | 0 | The cap changes the expected validity of affected cases; it does not produce a new value or invariant that unrelated pre-existing tests must additionally assert. |
|
| New test-framework primitives | 0 | A scalar boundary check and invalid-transaction or invalid-block expectations can be expressed with ordinary test cases; the proposal identifies no need for new framework abstractions. |
|
| Performance risks | 0 | The new operation is a fixed scalar validation check and does not itself require performance validation. The stated performance effects are reduced worst-case transaction load and more predictable block verification, not a new performance mechanism or risk. |
Uncertainty: The text motivates the numerical cap with performance concerns but supplies no benchmark methodology for validating the selected value. |
| Cryptography | 0 | The transaction gas-limit comparison introduces no cryptography. |
|
| Cross-EIP interactions | 0 | The sealed historical text names no other EIP and specifies no dependency, modification, or conflict requiring coordinated cross-EIP testing. |
