EIP Work Flow  Shepherding an EIP Parties involved in the process are you, the champion or EIP author, the EIP editors, and the Ethereum Core Developers. Before you begin writing a formal EIP, you should vet your idea. Ask the Ethereum community first if an idea is original to avoid wasting time on something that will be rejected based on prior research. It is thus recommended to open a discussion thread on the Ethereum Magicians forum to do this. Once the idea has been vetted, your next responsibility will be to present (by means of an EIP) the idea to the reviewers and all interested parties, invite editors, developers, and the community to give feedback on the aforementioned channels. You should try and gauge whether the interest in your EIP is commensurate with both the work involved in implementing it and how many parties will have to conform to it. For example, the work required for implementing a Core EIP will be much greater than for an ERC and the EIP will need sufficient interest from the Ethereum client teams. Negative community feedback will be taken into consideration and may prevent your EIP from moving past the Draft stage.  Core EIPs For Core EIPs, given that they require client implementations to be considered Final (see “EIPs Process” below), you will need to either provide an implementation for clients or convince clients to implement your EIP. The best way to get client implementers to review your EIP is to present it on an AllCoreDevs call. You can request to do so by posting a comment linking your EIP on an AllCoreDevs agenda GitHub Issue. The AllCoreDevs call serves as a way for client implementers to do three things. First, to discuss the technical merits of EIPs. Second, to gauge what other clients will be implementing. Third, to coordinate EIP implementation for network upgrades. These calls generally result in a “rough consensus” around what EIPs should be implemented. This “rough consensus” rests on the assumptions that EIPs are not contentious enough to cause a network split and that they are technically sound. :warning: The EIPs process and AllCoreDevs call were not designed to address contentious non-technical issues, but, due to the lack of other ways to address these, often end up entangled in them. This puts the burden on client implementers to try and gauge community sentiment, which hinders the technical coordination function of EIPs and AllCoreDevs calls. If you are shepherding an EIP, you can make the process of building community consensus easier by making sure that the Ethereum Magicians forum thread for your EIP includes or links to as much of the community discussion as possible and that various stakeholders are well-represented. In short, your role as the champion is to write the EIP using the style and format described below, shepherd the discussions in the appropriate forums, and build community consensus around the idea. ** EIP Process** The following is the standardization process for all EIPs in all tracks: Idea - An idea that is pre-draft. This is not tracked within the EIP Repository. Draft - The first formally tracked stage of an EIP in development. An EIP is merged by an EIP Editor into the EIP repository when properly formatted. Review - An EIP Author marks an EIP as ready for and requesting Peer Review. Last Call - This is the final review window for an EIP before moving to Final. An EIP editor will assign Last Call status and set a review end date (last-call-deadline), typically 14 days later. If this period results in necessary normative changes it will revert the EIP to Review. Final - This EIP represents the final standard. A Final EIP exists in a state of finality and should only be updated to correct errata and add non-normative clarifications. A PR moving an EIP from Last Call to Final SHOULD contain no changes other than the status update. Any content or editorial proposed change SHOULD be separate from this status-updating PR and committed prior to it. Stagnant - Any EIP in Draft or Review or Last Call if inactive for a period of 6 months or greater is moved to Stagnant. An EIP may be resurrected from this state by Authors or EIP Editors through moving it back to Draft or it’s earlier status. If not resurrected, a proposal may stay forever in this status.EIP Authors are notified of any algorithmic change to the status of their EIP Withdrawn - The EIP Author(s) have withdrawn the proposed EIP. This state has finality and can no longer be resurrected using this EIP number. If the idea is pursued at a later date it is considered a new proposal. Living - A special status for EIPs that are designed to be continually updated and not reach a state of finality. This includes most notably EIP-1.  What belongs in a successful EIP? Each EIP should have the following parts: • Preamble - RFC 822 style headers containing metadata about the EIP, including the EIP number, a short descriptive title (limited to a maximum of 44 characters), a description (limited to a maximum of 140 characters), and the author details. Irrespective of the category, the title and description should not include EIP number. See below for details. • Abstract - Abstract is a multi-sentence (short paragraph) technical summary. This should be a very terse and human-readable version of the specification section. Someone should be able to read only the abstract to get the gist of what this specification does. • Motivation (optional) - A motivation section is critical for EIPs that want to change the Ethereum protocol. It should clearly explain why the existing protocol specification is inadequate to address the problem that the EIP solves. This section may be omitted if the motivation is evident. • Specification - The technical specification should describe the syntax and semantics of any new feature. The specification should be detailed enough to allow competing, interoperable implementations for any of the current Ethereum platforms (besu, erigon, ethereumjs, go-ethereum, nethermind, or others). • Rationale - The rationale fleshes out the specification by describing what motivated the design and why particular design decisions were made. It should describe alternate designs that were considered and related work, e.g. how the feature is supported in other languages. The rationale should discuss important objections or concerns raised during discussion around the EIP. • Backwards Compatibility (optional) - All EIPs that introduce backwards incompatibilities must include a section describing these incompatibilities and their consequences. The EIP must explain how the author proposes to deal with these incompatibilities. This section may be omitted if the proposal does not introduce any backwards incompatibilities, but this section must be included if backward incompatibilities exist. • Test Cases (optional) - Test cases for an implementation are mandatory for EIPs that are affecting consensus changes. Tests should either be inlined in the EIP as data (such as input/expected output pairs, or included in ../assets/eip-###/<filename>. This section may be omitted for non-Core proposals. • Reference Implementation (optional) - An optional section that contains a reference/example implementation that people can use to assist in understanding or implementing this specification. This section may be omitted for all EIPs. • Security Considerations - All EIPs must contain a section that discusses the security implications/considerations relevant to the proposed change. Include information that might be important for security discussions, surfaces risks and can be used throughout the life-cycle of the proposal. E.g. include security-relevant design decisions, concerns, important discussions, implementation-specific guidance and pitfalls, an outline of threats and risks and how they are being addressed. EIP submissions missing the “Security Considerations” section will be rejected. An EIP cannot proceed to status “Final” without a Security Considerations discussion deemed sufficient by the reviewers. • Copyright Waiver - All EIPs must be in the public domain. The copyright waiver MUST link to the license file and use the following wording: Copyright and related rights waived via [CC0](/LICENSE).  EIP Formats and Templates EIPs should be written in markdown format. There is a template to follow.  EIP Header Preamble Each EIP must begin with an RFC 822 style header preamble, preceded and followed by three hyphens (---). This header is also termed “front matter” by Jekyll. The headers must appear in the following order. eip: EIP number title: The EIP title is a few words, not a complete sentence description: Description is one full (short) sentence author: The list of the author’s or authors’ name(s) and/or username(s), or name(s) and email(s). Details are below. discussions-to: The url pointing to the official discussion thread status: Draft, Review, Last Call, Final, Stagnant, Withdrawn, Living last-call-deadline: The date last call period ends on (Optional field, only needed when status is Last Call) type: One of Standards Track, Meta, or Informational category: One of Core, Networking, Interface, or ERC (Optional field, only needed for Standards Track EIPs) created: Date the EIP was created on requires: EIP number(s) (Optional field) withdrawal-reason: A sentence explaining why the EIP was withdrawn. (Optional field, only needed when status is Withdrawn) Headers that permit lists must separate elements with commas. Headers requiring dates will always do so in the format of ISO 8601 (yyyy-mm-dd).  author header The author header lists the names, email addresses or usernames of the authors/owners of the EIP. Those who prefer anonymity may use a username only, or a first name and a username. The format of the author header value must be:Random J. User [email protected] orRandom J. User (@username) orRandom J. User (@username) [email protected] if the email address and/or GitHub username is included, andRandom J. User if neither the email address nor the GitHub username are given. At least one author must use a GitHub username, in order to get notified on change requests and have the capability to approve or reject them.  discussions-to header While an EIP is a draft, a discussions-to header will indicate the URL where the EIP is being discussed. The preferred discussion URL is a topic on Ethereum Magicians. The URL cannot point to Github pull requests, any URL which is ephemeral, and any URL which can get locked over time (i.e. Reddit topics).  type header The type header specifies the type of EIP: Standards Track, Meta, or Informational. If the track is Standards please include the subcategory (core, networking, interface, or ERC).  category header The category header specifies the EIP’s category. This is required for standards-track EIPs only.  created header The created header records the date that the EIP was assigned a number. Both headers should be in yyyy-mm-dd format, e.g. 2001-08-14.  requires header EIPs may have a requires header, indicating the EIP numbers that this EIP depends on. If such a dependency exists, this field is required. A requires dependency is created when the current EIP cannot be understood or implemented without a concept or technical element from another EIP. Merely mentioning another EIP does not necessarily create such a dependency.  Linking to External Resources Other than the specific exceptions listed below, links to external resources SHOULD NOT be included. External resources may disappear, move, or change unexpectedly. The process governing permitted external resources is described in EIP-5757.  Execution Client Specifications Links to the Ethereum Execution Client Specifications may be included using normal markdown syntax, such as:

Which renders to: This is a sentence with a footnote.1 See the Citation Style Language Schema for the supported fields. In addition to passing validation against that schema, references must include a DOI and at least one URL. The top-level URL field must resolve to a copy of the referenced document which can be viewed at zero cost. Values under additional-urls must also resolve to a copy of the referenced document, but may charge a fee.  Linking to other EIPs References to other EIPs should follow the format EIP-N where N is the EIP number you are referring to. Each EIP that is referenced in an EIP MUST be accompanied by a relative markdown link the first time it is referenced, and MAY be accompanied by a link on subsequent references. The link MUST always be done via relative paths so that the links work in this GitHub repository, forks of this repository, the main EIPs site, mirrors of the main EIP site, etc. For example, you would link to this EIP as ./eip-1.md.  Auxiliary Files Images, diagrams and auxiliary files should be included in a subdirectory of the assets folder for that EIP as follows: assets/eip-N (where N is to be replaced with the EIP number). When linking to an image in the EIP, use relative links such as ../assets/eip-1/image.png.  Transferring EIP Ownership It occasionally becomes necessary to transfer ownership of EIPs to a new champion. In general, we’d like to retain the original author as a co-author of the transferred EIP, but that’s really up to the original author. A good reason to transfer ownership is because the original author no longer has the time or interest in updating it or following through with the EIP process, or has fallen off the face of the ‘net (i.e. is unreachable or isn’t responding to email). A bad reason to transfer ownership is because you don’t agree with the direction of the EIP. We try to build consensus around an EIP, but if that’s not possible, you can always submit a competing EIP. If you are interested in assuming ownership of an EIP, send a message asking to take over, addressed to both the original author and the EIP editor. If the original author doesn’t respond to the email in a timely manner, the EIP editor will make a unilateral decision (it’s not like such decisions can’t be reversed :)).  EIP Editors The current EIP editors are • Matt Garnett (@lightclient) • Sam Wilson (@SamWilsn) • Zainan Victor Zhou (@xinbenlv) • Gajinder Singh (@g11tech) Emeritus EIP editors are • Alex Beregszaszi (@axic) • Casey Detrio (@cdetrio) • Gavin John (@Pandapip1) • Greg Colvin (@gcolvin) • Hudson Jameson (@Souptacular) • Martin Becze (@wanderer) • Micah Zoltu (@MicahZoltu) • Nick Johnson (@arachnid) • Nick Savers (@nicksavers) • Vitalik Buterin (@vbuterin) If you would like to become an EIP editor, please check EIP-5069.  EIP Editor Responsibilities For each new EIP that comes in, an editor does the following: • Read the EIP to check if it is ready: sound and complete. The ideas must make technical sense, even if they don’t seem likely to get to final status. • The title should accurately describe the content. • Check the EIP for language (spelling, grammar, sentence structure, etc.), markup (GitHub flavored Markdown), code style If the EIP isn’t ready, the editor will send it back to the author for revision, with specific instructions. Once the EIP is ready for the repository, the EIP editor will: • Assign an EIP number (generally incremental; editors can reassign if number sniping is suspected) • Merge the corresponding pull request • Send a message back to the EIP author with the next step. Many EIPs are written and maintained by developers with write access to the Ethereum codebase. The EIP editors monitor EIP changes, and correct any structure, grammar, spelling, or markup mistakes we see. The editors don’t pass judgment on EIPs. We merely do the administrative & editorial part.  Style Guide  Titles The title field in the preamble: • Should not include the word “standard” or any variation thereof; and • Should not include the EIP’s number.  Descriptions The description field in the preamble: • Should not include the word “standard” or any variation thereof; and • Should not include the EIP’s number.  EIP numbers When referring to an EIP with a category of ERC, it must be written in the hyphenated form ERC-X where X is that EIP’s assigned number. When referring to EIPs with any other category, it must be written in the hyphenated form EIP-X where X is that EIP’s assigned number.  RFC 2119 and RFC 8174 EIPs are encouraged to follow RFC 2119 and RFC 8174 for terminology and to insert the following at the beginning of the Specification section:The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “NOT RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119 and RFC 8174.  History This document was derived heavily from Bitcoin’s BIP-0001 written by Amir Taaki which in turn was derived from Python’s PEP-0001. In many places text was simply copied and modified. Although the PEP-0001 text was written by Barry Warsaw, Jeremy Hylton, and David Goodger, they are not responsible for its use in the Ethereum Improvement Process, and should not be bothered with technical questions specific to Ethereum or the EIP. Please direct all comments to the EIP editors.  Copyright Copyright and related rights waived via CC0.
