This repository contains early-stage research of interest to the blockchain community.

Blockchain Commons Research papers (BCRs) are not standards. They are fluid specifications, typically based on our own libraries or other coding. Because of their fluidity, BCRs might change without notice. If you decide to adopt a Blockchain Commons Research paper, you are becoming a Research Partner, examining how the specification might work in the real world. We look forward to working with you!

If you are using the specifications from a BCR, please let us know. Having a BCR in usage by at least two parties other than Blockchain Commons is one of our criteria for advancing a BCR to a Blockchain Commons Proposal (BCP), increasing its stability. If you can only use a specification if it is advanced to the BCP stage, sldo let us know that, as we sometimes advance BCRs on our own if they have achieved sufficient maturity.

Generally, it's only if a BCR advances to the BCP stage that we more deeply involve community in its continued maturation and focus on it becoming an actual standard.

Each BCR has a status which is indicated by a symbol.

❌❌ after another status symbol is read, "...but withdrawn" and ❌ is read, "...but superseded".

Also see our Testimony and our Blockchain Commons Proposals.

Please feel free to submit your own Drafts of BCRs for specifications that support the creation of open, interoperable, secure & compassionate digital infrastructure to this repo as PRs, as follows.

All contributions to this repo require a Signed Contributor License Agreement (which will be needed if we submit to other organizations like IETF, W3C, Linux Foundation, etc.).

Please number all Bitcoin Research BCRs with a four-digit number representing the current year (YYYY) followed by a three-digit sequence number for that year (SSS). For example: bcr-2020-001 is the first BCR for 2020, bcr-2020-017 is the 17th, and bcr-2021-001 is the first BCR for 2021.

Note that the sequence number reverts to 001 at the start of each year.

Please be sure that your title is concise, yet informative.

When updating BCRs, please use semantic versioning for your version number.

Most briefly: your version number should be of the form X.Y.Z, where X is the major number ("0" for a BCR Draft; "1" for something ready to become a BCR Work Product; and "2" or higher for a new version that has introduced a backward-incompatible change), Y is the minor number (for a backward-compatible new feature), and Z is the patch number (for fixing typos and making other clarifications that don't fundamentally change what the BCR means).

But please consult the semantic versioning document for more information and adjust appropriately for the fact that these are textual BCRs, not software.

Please list the person primarily responsible for the BCR, and moving it forward, as the owner. If there are multiple authors, they should be listed on the BCR itself, not on this overview.

This research is a project of Blockchain Commons. We are proudly a "not-for-profit" social benefit corporation committed to open source & open development. Our work is funded entirely by donations and collaborative partnerships with people like you. Every contribution will be spent on building open tools, technologies, and techniques that sustain and advance blockchain and internet security infrastructure and promote an open web.

To financially support further development of this research and other projects, please consider becoming a Patron of Blockchain Commons through ongoing monthly patronage as a GitHub Sponsor. You can also support Blockchain Commons with bitcoins at our BTCPay Server.

We encourage public contributions through issues and pull requests! Please review CONTRIBUTING.md for details on our development process. All contributions to this repository require a GPG signed Contributor License Agreement.

The best place to talk about Blockchain Commons and its projects is in our GitHub Discussions areas.

Gordian Developer Community. For standards and open-source developers who want to talk about interoperable wallet specifications, please use the Discussions area of the Gordian Developer Community repo. This is where you talk about Gordian specifications such as Gordian Envelope, bc-shamir, Sharded Secret Key Reconstruction, and bc-ur as well as the larger Gordian Architecture, its Principles of independence, privacy, resilience, and openness, and its macro-architectural ideas such as functional partition (including airgapping, the original name of this community).

Blockchain Commons Discussions. For developers, interns, and patrons of Blockchain Commons, please use the discussions area of the Community repo to talk about general Blockchain Commons issues, the intern program, or topics other than those covered by the Gordian Developer Community or the Gordian User Community.

As an open-source, open-development community, Blockchain Commons does not have the resources to provide direct support of our projects. Please consider the discussions area as a locale where you might get answers to questions. Alternatively, please use this repository's issues feature. Unfortunately, we can not make any promises on response time.

If your company requires support to use our projects, please feel free to contact us directly about options. We may be able to offer you a contract for support from one of our contributors, or we might be able to point you to another entity who can offer the contractual support that you need.

The following people directly contributed to this repository. You can add your name here by getting involved. The first step is learning how to contribute from our CONTRIBUTING.md documentation.

We want to keep all of our software safe for everyone. If you have discovered a security vulnerability, we appreciate your help in disclosing it to us in a responsible manner. We are unfortunately not able to offer bug bounties at this time.

We do ask that you offer us good faith and use best efforts not to leak information or harm any user, their data, or our developer community. Please give us a reasonable amount of time to fix the issue before you publish it. Do not defraud our users or us in the process of discovery. We promise not to bring legal action against researchers who point out a problem provided they do their best to follow the these guidelines.

Please report suspected security vulnerabilities in private via email to ChristopherA@BlockchainCommons.com (do not use this email for support). Please do NOT create publicly viewable issues for suspected security vulnerabilities.

The following keys may be used to communicate sensitive information to developers:

You can import a key by running the following command with that individual’s fingerprint: gpg --recv-keys "<fingerprint>" Ensure that you put quotes around fingerprints that contain spaces.
