This proposal introduces a gas discount for contract deployments when the bytecode being deployed already exists in the state. The mechanism extends EIP-2930 access lists with an optional checkCodeHash flag to enable deterministic deduplication checks without breaking consensus.

Key features:

  • Access-list based deduplication via checkCodeHash flag
  • Avoids GAS_CODE_DEPOSIT * L costs for duplicate deployments
  • Solves database divergence issues across different sync modes
  • Becomes particularly relevant with EIP-8037's increased gas costs

This EIP is extracted from the original EIP-8037 proposal to allow independent review and adoption.

This EIP doesn't modify any interaction between users and the chain if not used. Meaning, users will get discounts if they use the EIP. They'll pay the same exact price as they do now if they don't use this EIP.

EIPS/eip-draft.md Outdated
Any address included in the access list automatically contributes to deduplication. This provides automatic gas optimization without requiring explicit flags or special handling.

5. Avoids chain split risks:
Since no new transaction structure is introduced, pre-fork and post-fork nodes handle the same transactions identically (just with different gas accounting post-fork). This eliminates the risk of chain splits from nodes rejecting transactions with unknown fields.

* Add EIP: Contract Bytecode Deduplication Discount (ethereum#10585)

* Add draft EIP: Contract Bytecode Deduplication Discount

This proposal introduces a gas discount for contract deployments when the
bytecode being deployed already exists in the state. The mechanism extends
EIP-2930 access lists with an optional checkCodeHash flag to enable
deterministic deduplication checks without breaking consensus.

Key features:
- Access-list based deduplication via checkCodeHash flag
- Avoids GAS_CODE_DEPOSIT * L costs for duplicate deployments
- Solves database divergence issues across different sync modes
- Becomes particularly relevant with EIP-8037's increased gas costs

This EIP is extracted from the original EIP-8037 proposal to allow
independent review and adoption.

* Address PR review comments and switch to implicit deduplication

Major changes:
1. Remove checkCodeHash flag - make deduplication implicit via access lists
2. Add co-authors Wei-Han and Guillaume Ballet
3. Fix grammar: behaviour -> behavior, formalise -> formalize
4. Update snap-sync description for technical accuracy
5. Clarify edge cases for same-block deployments
6. Move Same-Block Deployments section from Rationale to Specification
7. Add rationale explaining why implicit design avoids chain splits

Reviewer feedback addressed:
- @weiihann: Remove explicit checkCodeHash flag, use implicit checking
- @gballet: Chain split concerns resolved by implicit design
- @gballet: Grammar and technical accuracy fixes
- @weiihann: Simplify empty code handling
- @weiihann: Clarify same-block deployment edge cases

The implicit design provides several advantages:
- No protocol changes to access list structure
- Avoids chain split risks from unknown transaction fields
- Simpler implementation - any address in access list contributes
- Automatic optimization without explicit opt-in flags

* Address additional review comments from Guillaume

- Simplify deduplication logic to more concise form
- Remove pre-fork/post-fork language from chain split rationale
- Clarify that only gas accounting changes at fork activation
