Documents

Blockchain Commons has produced a variety of documentation of interest to developers and users of blockchains.

The Crypto Commons

Our crypto-commons specifications, reference tools, and libraries offer new interoperable methodologies for cryptocurrency wallets, and may be of interest to developers and users.

General

Key Derivation Names

Sharded Secret Key Reconstruction (SSKR)

SSKRs allow a seed to be sharded into shares that can be stored as words, URs, or QRs.

SSKR for Users
- SSKR Cold Storage
- SSKR Video Example
SSKR for Developers
- SSKR Test Vector

For an even more comprehensive list, please see our SSKR overview page, which includes links to research papers, references, code, and other material from other repos, all intended to support your understanding of SSKR, whether you're a user, a power user, or a developer.

Uniform Resources (URs)

URs allow for the interoperable transmission and storage of a variety of information, especially cryptographic data.

URs: An Introduction
crypto-request and crypto-response vs Signing via crypto-psbt
ur:crypto-request test vectors
ur:crypto-seed test vectors

One of the important aspects of URs was that they allowed for the introduction of Animated QRs:

We also have a more comprehensive UR overview page that includes links to research papers, references, code, and other material of interest primarily to UR developers.

Coming Soon

We are planning one more UR article in the near future, detailing how to use URs with PSBTs.

Please feel free to file an issue if there's more Crypto Commons specifications that you'd like to see with more extensive documents.
