# Bytecode Alliance Organizational Code of Conduct (OCoC)
*Note*: this Code of Conduct pertains to organizations' behavior. Please also see the [Individual Code of Conduct](CODE_OF_CONDUCT.md).
## Preamble
The Bytecode Alliance (BA) welcomes involvement from organizations,
including commercial organizations. This document is an
*organizational* code of conduct, intended particularly to provide
guidance to commercial organizations. It is distinct from the
[Individual Code of Conduct (ICoC)](CODE_OF_CONDUCT.md), and does not
replace the ICoC. This OCoC applies to any group of people acting in
concert as a BA member or as a participant in BA activities, whether
or not that group is formally incorporated in some jurisdiction.
The code of conduct described below is not a set of rigid rules, and
we did not write it to encompass every conceivable scenario that might
arise. For example, it is theoretically possible there would be times
when asserting patents is in the best interest of the BA community as
a whole. In such instances, consult with the BA, strive for
consensus, and interpret these rules with an intent that is generous
to the community the BA serves.
While we may revise these guidelines from time to time based on
real-world experience, overall they are based on a simple principle:
*Bytecode Alliance members should observe the distinction between
public community functions and private functions — especially
commercial ones — and should ensure that the latter support, or at
least do not harm, the former.*
## Guidelines
* **Do not cause confusion about Wasm standards or interoperability.**
Having an interoperable WebAssembly core is a high priority for
the BA, and members should strive to preserve that core. It is fine
to develop additional non-standard features or APIs, but they
should always be clearly distinguished from the core interoperable
Wasm.
Treat the WebAssembly name and any BA-associated names with
respect, and follow BA trademark and branding guidelines. If you
distribute a customized version of software originally produced by
the BA, or if you build a product or service using BA-derived
software, use names that clearly distinguish your work from the
original. (You should still provide proper attribution to the
original, of course, wherever such attribution would normally be
given.)
Further, do not use the WebAssembly name or BA-associated names in
other public namespaces in ways that could cause confusion, e.g.,
in company names, names of commercial service offerings, domain
names, publicly-visible social media accounts or online service
accounts, etc. It may sometimes be reasonable, however, to
register such a name in a new namespace and then immediately donate
control of that account to the BA, because that would help the project
maintain its identity.
* **Do not restrict contributors.** If your company requires
employees or contractors to sign non-compete agreements, those
agreements must not prevent people from participating in the BA or
contributing to related projects.
This does not mean that all non-compete agreements are incompatible
with this code of conduct. For example, a company may restrict an
employee's ability to solicit the company's customers. However, an
agreement must not block any form of technical or social
participation in BA activities, including but not limited to the
implementation of particular features.
The accumulation of experience and expertise in individual persons,
who are ultimately free to direct their energy and attention as
they decide, is one of the most important drivers of progress in
open source projects. A company that limits this freedom may hinder
the success of the BA's efforts.
* **Do not use patents as offensive weapons.** If any BA participant
prevents the adoption or development of BA technologies by
asserting its patents, that undermines the purpose of the
coalition. The collaboration fostered by the BA cannot include
members who act to undermine its work.
* **Practice responsible disclosure** for security vulnerabilities.
Use designated, non-public reporting channels to disclose technical
vulnerabilities, and give the project a reasonable period to
respond, remediate, and patch.
Vulnerability reporters may patch their company's own offerings, as
long as that patching does not significantly delay the reporting of
the vulnerability. Vulnerability information should never be used
for unilateral commercial advantage. Vendors may legitimately
compete on the speed and reliability with which they deploy
security fixes, but withholding vulnerability information damages
everyone in the long run by risking harm to the BA project's
reputation and to the security of all users.
* **Respect the letter and spirit of open source practice.** While
there is not space to list here all possible aspects of standard
open source practice, some examples will help show what we mean:
* Abide by all applicable open source license terms. Do not engage
in copyright violation or misattribution of any kind.
* Do not claim others' ideas or designs as your own.
* When others engage in publicly visible work (e.g., an upcoming
demo that is coordinated in a public issue tracker), do not
unilaterally announce early releases or early demonstrations of
that work ahead of their schedule in order to secure private
advantage (such as marketplace advantage) for yourself.
The BA reserves the right to determine what constitutes good open
source practices and to take action as it deems appropriate to
encourage, and if necessary enforce, such practices.
## Enforcement
Instances of organizational behavior in violation of the OCoC may
be reported by contacting the Bytecode Alliance CoC team at
[report@bytecodealliance.org](mailto:report@bytecodealliance.org). The
CoC team will review and investigate all complaints, and will respond
in a way that it deems appropriate to the circumstances. The CoC team
is obligated to maintain confidentiality with regard to the reporter of
an incident. Further details of specific enforcement policies may be
posted separately.
When the BA deems an organization in violation of this OCoC, the BA
will, at its sole discretion, determine what action to take. The BA
will decide what type, degree, and duration of corrective action is
needed, if any, before a violating organization can be considered for
membership (if it was not already a member) or can have its membership
reinstated (if it was a member and the BA canceled its membership due
to the violation).
In practice, the BA's first approach will be to start a conversation,
with punitive enforcement used only as a last resort. Violations
often turn out to be unintentional and swiftly correctable with all
parties acting in good faith.

# Security Policy
Building secure foundations for software development is at the core of what we do in the Bytecode Alliance. Contributions of external security researchers are a vital part of that.
## Scope
If you believe you've found a security issue in any website, service, or software owned or operated by the Bytecode Alliance, we encourage you to notify us.
## How to Submit a Report
To submit a vulnerability report to the Bytecode Alliance, please contact us at [security@bytecodealliance.org](mailto:security@bytecodealliance.org). Your submission will be reviewed and validated by a member of our security team.
## Safe Harbor
The Bytecode Alliance supports safe harbor for security researchers who:
* Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our services.
* Only interact with accounts you own or with explicit permission of the account holder. If you do encounter Personally Identifiable Information (PII) contact us immediately, do not proceed with access, and immediately purge any local information.
* Provide us with a reasonable amount of time to resolve vulnerabilities prior to any disclosure to the public or a third-party.
We will consider activities conducted consistent with this policy to constitute "authorized" conduct and will not pursue civil action or initiate a complaint to law enforcement. We will help to the extent we can if legal action is initiated by a third party against you.
Please submit a report to us before engaging in conduct that may be inconsistent with or unaddressed by this policy.
## Preferences
* Please provide detailed reports with reproducible steps and a clearly defined impact.
* Submit one vulnerability per report.
* Social engineering (e.g. phishing, vishing, smishing) is prohibited.

Object form, made available under the License, as indicated by a
copyright notice that is included in or attached to the work
(an example is provided in the Appendix below).
"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the

separable from, or merely link (or bind by name) to the interfaces of,
the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner
or by an individual or Legal Entity authorized to submit on behalf of

on behalf of whom a Contribution has been received by Licensor and
subsequently incorporated within the Work.
2. Grant of Copyright License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works

attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must

pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade

WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

Creative Commons Legal Code
CC0 1.0 Universal
CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
HEREUNDER.
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to
this CC0 or use of the Work.
