Empty accounts deprecation
EIP 7523. Peter Davies.
EIP 7523, Empty accounts deprecation. This EIP prohibits the state of any post-merge network from containing empty accounts.
Status in the source: Last Call. A reading of the public specification, not a copy of it and not a certification.
Empty accounts deprecation is worth reading for the rule it actually adds: This EIP prohibits the state of any post-merge network from containing empty accounts.
The five-minute read
The rule
This EIP prohibits the state of any post-merge network from containing empty accounts.
What was already failing
An underpriced or ambiguous EVM rule is not a feature. It is a block that takes longer than the gas limit claimed, or a client that disagrees about the result.
What the number does not mean
The source marks this last call. It is not a live consensus rule just because it has a number.
What a builder should be able to point at
An implementation either constrains EVM or it is a different design.
One action, walked through
- Open EIP 7523 and read the status line before the examples.
- Write down the rule in one sentence. A fair version of that sentence is: This EIP prohibits the state of any post-merge network from containing empty accounts.
- Name the object that changes: EVM.
- Ask what an old client, an old contract, or an offline counterparty does. If the document is silent, the silence is part of the design.
The argument, unpacked
What the text is allowed to settle
Ethereum Improvement Proposal 7523 can settle the shape of Empty accounts deprecation. It cannot settle whether a later client, a later fork, or a later wallet still does this.
What this page will not pretend
There is no benchmark, no adoption number, and no claim that the mechanism is safe outside the assumptions written in the source.
What has to be true
- You are implementing EIP 7523 at the status the text itself states: Last Call.
- The object that has to change is EVM. A neighbouring document with a similar name is not this one.
- Constants in the text can be superseded by a later fork. Cite the EIP number and the fork you mean.
What happened after the paper
The source marks this last call. It is not a live consensus rule just because it has a number. Later documents can narrow, replace, or ignore this one. Cite the number you mean.
What to check before you use the idea
- What does Empty accounts deprecation charge, reject, or redefine on the first touch versus a later one?
- Does a reverted subcall roll the change back?
- Can you point at the object in a client: EVM?
Terms
- EIP 7523
- The public text titled Empty accounts deprecation.
- Last Call
- The document's own label for how finished the text is. It is not a market fact.
The problem the paper names
An underpriced or ambiguous EVM rule is not a feature. It is a block that takes longer than the gas limit claimed, or a client that disagrees about the result.
What the design proposes
- This EIP prohibits the state of any post-merge network from containing empty accounts.
- Since no empty accounts exist outside the testsuite and no new ones can be created this requirement is already achieved in practice.
- An explicit ban reduces technical debt going forward.
How the mechanism is specified
- Taken from the specification, the next constraint is: Since no empty accounts exist outside the testsuite and no new ones can be created this requirement is already achieved in practice.
- Locate EVM in EIP 7523 and apply it to one transaction or call.
- Then check the failure the class of rule always has: a node that did not upgrade, a reverted call, a replayed signature, or a peer that does not speak the message.
What this page does not treat as proven
- A gas or opcode change is not a throughput benchmark. It is a relative price and a validity rule.
- Constants in the text can be superseded by a later fork. Cite the EIP number and the fork you mean.
- The source marks this last call. It is not a live consensus rule just because it has a number.
Why a venture studio still reads it
Use EIP 7523 when a pitch says 'Empty accounts deprecation' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
