December 1, 2023

Repository infrastructure -> 0.3.0

  • New monorepo https://github.com/Galactica-corp/galactica-monorepo integrating the previous repositories galactica-snap and zkKYC (PR#14)

  • Monorepo also containing two new packages galactica-types and galactica-snap-api

  • Improved continuous integration

    • Speeding up Github actions pipeline with caching

    • Integrating new monorepo packages

  • Integrated turbo build system for faster incremental builds on changes during development (PR#18)

Galactica ZK Vault Snap -> 0.6.1

  • Version audited by Sayfer for integration in the stable version of Metamask. Audit fixes (PR#33) including:

    • Simplified installation of test setup, improved notifications and error messages

    • Removed unused functions

    • Resolved and cleaned up TODO comments in the code

    • URL validation for custom Merkle proof sources

  • Option to renew zkCerts when a new one is imported with the same registry address and Merkle tree position (PR#12)

  • Improved security and privacy of ZKP disclosures by giving the user a complete and transparent list of disclosed statements in the confirmation question (PR#13)

  • Better structured and typed API interface using definitions from the new snap-api package. Check the docs for details. It simplifies sending calls from the front-end and changes parameter, return and error types. (PR#14, PR#20)

    • `getHolderCommitment`

      • Also returns an encryption

      • Together with the holder commitment in an object

    • `genZkKycProof`

      • Wasm, zkHeader and zkSections now in one prover object

      • Requires descriptions of fields disclosed in public input of resulting ZKP

      • Requires registry address field relevant for the zkCert that can be used

      • Renamed general description field of ZKP

    • `importZkCert`

      • Now takes encrypted zkCert as input

    • `exportZkCert`

      • Result is an encrypted zkCert

      • Optional expiration date and provider pubkey parameters to simplify selection

    • `updateMerkleProofURL`

      • New method to change the URL to query Merkle proofs from

    • All return values are objects

    • Throwing typed errors

  • ZkCerts are now encrypted outside the Snap storage with a public/private key pair generated in the Snap. Therefore the holderCommitment is returned with the public key for encryption to send it to the provider. (PR#17)

  • Possibility to update Merkle Proofs via function or node service to support revocable zkCert registries (PR#19)

  • Outsourced general type definitions to galactica-types and snap-api

  • Various small fixes and improvements

ZK-Certificates -> 0.9.5

  • Renamed from zkKYC to zk-certificates to represent generalized purpose

  • ZkKYC encryption after generation according to PR#17

  • Added zkCert registries with revocable entries to satisfy KYC guardiansโ€™ need. Implemented with sparse Merkle trees (PR#24 in zkKYC)

  • New smart contract example accepting repeatable zkKYC proofs (PR#25 in zkKYC)

  • Scripts and tooling to reissue and update expiration dates of zkKYCs (PR#28 in zkKYC)

  • Outsourced general type definitions to galactica-types (PR#30 in zkKYC)

  • Proper continuous integration and testing in GitHub Actions pipeline (PR#21)

  • Guardian registry improvements to identify guardians using a mapping of public EdDSA key to address and names (PR#23)

  • Improved EdDSA key generation and type handling (PR#32)
