This release (0.12.0) is considered stable and production-ready. It can safely be deployed in public and production environments.

This release includes PC1.5 and BLS support and uses the new storage model.

Key Changes & Highlights​

note

This change requires a chain-reset for our production environment (testnet-02)

  • Switch field/curves from Pluto-Eris to BLS12-381

    • Why: smaller and faster proofs. 10x smaller public params (500Mb->50Mb).

  • Switch to new storage model

    • Faster performance no longer tied to size of ledger state

  • PC1.5
