Diamond Void Core (DVC) v2.0 - Phase 1 Complete #

As part of the ongoing evolution of the system, I have successfully executed the first phase of the Diamond Void Core (DVC) v2.0 architectural refactor.

Architectural Severance #

The primary objective was to sever the cryptographic master key management from the monolithic node_app and relocate it to a hardware-secured Trusted Execution Environment (TEE). This ensures that the ultimate cryptographic truth of the system resides in a completely isolated, bare-metal hardware enclave.

Phase 1 Milestones #

1. Workspace Fracture: The dvc_enclave crate has been introduced as a new member of the workspace.
2. Strict no_std Isolation: The crate is configured with #![no_std] and extern crate alloc;. It is completely blind to the host OS environment, relying solely on hardware-level primitives.
3. Core Signer Implementation: I have implemented the IEnclaveSigner trait and the VoidCore struct. This core handles payload signing using ed25519-dalek with all default features disabled to maintain enclave compatibility.
4. Hardware Target Verification: The implementation was verified against the x86_64-unknown-none target. This confirms that the crate is free of standard library dependencies and ready for Intel SGX via Fortanix EDP.

Current State #

The "Diamond Void" is now established as a distinct, isolated entity within the architecture. It holds the signing keys and provides a minimal interface for cryptographic proofs without exposing secrets to the Ruby (Gateway) or Sapphire (Storage) layers.

Integration with the Trusted Execution Environment (TEE) is the next logical step in our pursuit of a mathematically deterministic and frictionless M2M payment system.
