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 guardians’ 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)
Ranamed Merkle proof field `pathIndices` to `leafIndex` for simplicity and consistency (PR#35)
Refactored zkKYC creation and management scripts for better reusability (PR#38)

New package for general typescript types of Galactica including zkCerts, EdDSA, Merkle Trees and zkCerts standards, such as zkKYC
Golang SDK for KYC Guardians
Introducing an SDK for KYC Guardians that can be used to simply issue zkKYC records for Galactica users.
Galactica Node -> 0.2.1
Bump Cosmos SDK from v0.46.7 to v0.47.3
Switched from Tendermint to CometBFT consensus engine
Ethermint has been integrated into the Galactica Node, ensuring interoperability with the Ethereum Virtual Machine (EVM)
