  • A follow-up phase will build on the previous foundation of the SDK to support coordinated state management across multiple parties. The SDK will expose APIs for encrypted state persistence, retrieval, and access control, and support multiple backend configurations (e.g., centralized servers, committee-based services, or decentralized networks like IPFS or Gun DB). In this second phase we will complete the development of a Confidential General-Purpose Multisig, based on previous work from Milestone 1, leveraging improvements on the SDK, and enabling full workflows for note transfers and account recovery, as well as potentially other features scoped by the end of the previous milestone.

  • Build the minimal version of the Private State Manager (PSM) capable of managing and synchronizing transparent (non-encrypted) account states and deltas for Miden accounts. The MVP must enable cosigners to push, pull, and synchronize account state updates through the PSM, while preserving on-chain sync (canonicalization process). During this phase we will also design and implement a proof-of-concept multisig enabling M-of-N signing workflows. This will include the design and initial implementation of necessary smart contract components, and will also include research on key features to include in the development of the general purpose multisig for Milestone 2.
