Developer Libraries

2018.06.26 13:00-14:00 Jack (Str4d) Grigg

The workshop was mainly a discussion on what kind of libraries and tools are needed in the ZCash ecosystem

The state of ZCash Libraries now:

  • Zcash libraries are mostly ported from Bitcoin ones

    • Libraries with t-address support
      • Bitcore
      • python-bitcoinlib
      • z-nomp

  • Shielded Addresses

    • Nothing!

  • Most of the codes are in Rust

    • Librustzcash
    • Libwallet-zcash
      • What functionalities do we want it to do?
    • Also used in Zcash Fullnode

  • Discussion on what do we need?

    • In-browser Signing / Creation of transactions
    • cross-language tools
    • Need for a curated list of dev tools
    • APIs for humans and machines

  • Back to where dev tools are required: -- Low friction - Convenience: --- Browser --- Docker --- Packages with every language (npm, pip)

  • Operations required for such libraries to do: -- Address creation --- ZIP32 -- Address (key) Management -- Signing --- Multi-signature Architecture -- Proving -- Payment detection -- UTXO Management -- Serialization
