Galactica Monorepo v0.6.0

What's Changed

ZK-Certificates -> 0.11.0

• The guardian registry smart contract now links to a metadata URL with information and it allows guardians to use multiple accounts for issuing zkCerts (#61)
• New sybil-resistant airdrop smart contract based on zkKYC registrations with humanID (#64)
• New sybil-resistant faucet smart contract based on zkKYC (#66)
• Added a salt to the humanID for more privacy and tracking resistance (#67)
• Fixed non-deterministic poseidon hash of “” (#69)
• New script for debugging encrypted zkCerts (#70)
• New Zk circuit for country sanction list (#72)
• New Compliant ERC20 demo and smart contracts (#72)
• Added a multicall smart contract (#74)
• New smart contracts and ZK circuits for Twitter related proofs and how they are stored and managed in VerificationSBTs (#74)
• New smart contracts for basic zkKYC proofs in new Galactica passport front-end (#75)
• ZkCert hashes of key-value records are now alphabetically ordered. This ensures consistency, with future zkCerts and new content types. This changes the hashes of existing zkCerts and therefore requires updating the zkCert generation and ZK prover accordingly. To separate zkCerts with the hashing approach, we also created new zkCert registry instances on-chain. (#76)
• Script for whitelisting guardians based on compressed EdDSA public keys (#78)

Galactica ZK Vault Snap -> 0.8.1

• New method to benchmark ZK proof generation (#63)
• Allow snap to handle larger, more complex ZK provers by moving them out of the request payload (#65)
• Fixed compatibility issue with unknown zkCert types (#73)

Snap-API -> 0.3.0

• Adjusted to new methods and parameter types (#63, #65)

Galactica-Types -> 0.4.0

• New zkCert standards for Twitter, Rey and DEX certificates (#71, #73)
• Removed root field from merkle proof type to remove a potential source of inconsistency (#79)

Example and Test Front-Ends -> 0.4.0

• Integrated snap benchmark button (#63)
• Integrated CompliantERC20 demo (#72)

Galactica Monorepo v0.3.0 (for DevNet v2 Andromeda)

Changelog

Comparing current version for DevNet v2.0: Andromeda with the previous DevNet (corresponding with Snap v0.4.4).

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)
