vac:nes:

  • state-separation-architecture-poc:doc

    • Researched cross-call programs: Looked into Solana-style CPI for structure (A passes B’s program ID + B’s accounts, VM jumps to B), but also into Aztec-style privacy for execution (calls/args/who-called-whom can be kept private, with public outputs only where one can choose).
    • Analyzed how Aztec uses cross-call programs: had to go through all the documentation since there is few info about it. Apparently, Aztec use it unilaterally (private to public only).
    • Drafted a document explaining the before-mentioned approaches.

    • Implementation of privacy-preserving transactions on wallet. PR 115
