调研方向

首先将项目范围缩小到所列工作流中的一个，然后阅读链接的 did:key、multibase、SchnorrSecp256k1Signature2019 和 BTCR v0 resources.md 材料。Issue 提到了参考 JavaScript 代码、测试向量、规范和示例，但没有指出仓库文件或测试。在开始之前，先定义一个单一的交付物及其验收标准。

描述

good first issue intern project

This would be a good group project for interns interested in internal standards and self-sovereign identity, and with different skills (writing specs, testing, coding javascript, coding C or rust, writing documentation, etc.)

Few of the emerging W3C DID (Decentralized Identifier) methods are using secp256k1 (the curve that bitcoin uses). In addition, none of that I know are actively implementing Schnorr signatures for k1, and even those in spec-only form are not making some of the choices that BIP40 made, or leverage Schnorr in sufficiently security reviewed libsecp256k1 library. Finally, no one in implementing DIDs currently are leveraging the multisig opportunities Schnorr, including musig2, FROST, adapter signatures, blinded signatures, etc.

In particular:

  • Write up use cases for what secp256k1 can offer leveraging k1 multisig to DIDs and Verifiable Credentials.
  • Suggest changes and test vectors for existing did:key method to support k1 and Schnorr.
  • Write reference code in javascript and other languages to transorm BIP340 keys into multibase & back, and register those with next update to the IETF internet-draft.
  • Update DIF (Decentralized Identity Foundation) JSON-LD SchnorrSecp256k1Signature2019https://github.com/decentralized-identity/SchnorrSecp256k1Signature2019) spec for BIP340 differences, and update test vectors.
  • Update reference javascript library for JSON-LD SchnorrSecp256k1Signature2019 and investigate other implementations.
  • Investigate JWT support of k1 Schnorr rather than ECDSA. Possibly submit IETF internet-draft or PR to JWT group to add k1 Schnorr.
  • Work toward a CBOR-LD version of SchnorrSecp256k1Signature2019
  • Create example DID objects and Verifiable Credentials leveraging SchnorrSecp256k1Signature2019
  • Investigate Ristretto255 versions of the above.
  • Present these at W3C CCG (Credentials Community Group) and DIF.

Related to this is beginning to be able to did:btcr 2.0 someday, see:
