Overview ¶
Package mpcvm re-exports the canonical Threshold (FHE / MPC) VM from github.com/luxfi/chains/mpcvm so existing callers that imported github.com/luxfi/node/vms/mpcvm pre-extraction keep working without source changes.
New code should import the canonical path:
"github.com/luxfi/chains/mpcvm"
This file is a thin alias wrapper kept for backward compatibility.
Index ¶
Constants ¶
const ( GPUBackendNone = mpcvm.GPUBackendNone GPUBackendCUDA = mpcvm.GPUBackendCUDA GPUBackendHIP = mpcvm.GPUBackendHIP GPUBackendMetal = mpcvm.GPUBackendMetal GPUBackendVulkan = mpcvm.GPUBackendVulkan GPUBackendWebGPU = mpcvm.GPUBackendWebGPU )
Backend constants re-exported. Matches the chains/mpcvm dlopen probe order: cuda → hip → metal → vulkan → webgpu.
Variables ¶
var ( ErrInvalidOperation = mpcvm.ErrInvalidOperation NewClient = mpcvm.NewClient )
var ErrGPUNotAvailable = mpcvm.ErrGPUNotAvailable
ErrGPUNotAvailable is the canonical "no plugin loaded" error. Callers `errors.Is(err, mpcvm.ErrGPUNotAvailable)` to distinguish a fallback-to-CPU condition from a hard launcher failure.
Functions ¶

Types ¶
type BlockError ¶
type BlockError = mpcvm.BlockError
type GPUBackend ¶
type GPUBackend = mpcvm.GPUBackend
func GPUBackendInstance ¶
func GPUBackendInstance() *GPUBackend
GPUBackendInstance returns the dlopen'd GPU plugin handle resolved at chains/mpcvm package init. nil means no plugin was loaded (CPU-only mode). The handle is shared across the whole process — both the node and chains paths see the same instance.
The name is GPUBackendInstance (not GPUBackend / Backend) because Go disallows a function named the same as a type alias in the same package, and `Backend` is already a domain term in the threshold state machine. Callers write:
if g := mpcvm.GPUBackendInstance(); g != nil && g.IsAvailable() {
_, err := g.CeremonyApply(desc, ops, ceremonies)
...
}
This mirrors the cevm pattern `cevm.AvailableBackends()` / `cevm.LibraryABIVersion()` — discovery via package-scope function, not via a global variable.
func SelectGPUBackend ¶
func SelectGPUBackend() (*GPUBackend, string)
SelectGPUBackend returns the resolved GPU plugin (or nil) and a single human-readable diagnostic string. luxd startup logs use this to surface "mpcvm-gpu backend=<name>" lines alongside the cevm backend selection, matching the cevm.go pattern at ~/work/lux/chains/evm/backend_cgo.go.
Calling this multiple times is cheap — the underlying probe runs once at package init via sync.Once in chains/mpcvm/backend.go.
type GPUBackendKind ¶
type GPUBackendKind = mpcvm.GPUBackendKind
type GPUCeremony ¶
type GPUCeremony = mpcvm.GPUCeremony
type GPUCeremonyOp ¶
type GPUCeremonyOp = mpcvm.GPUCeremonyOp
type GPUContribution ¶
type GPUContribution = mpcvm.GPUContribution
type GPUContributionOp ¶
type GPUContributionOp = mpcvm.GPUContributionOp
type GPUKeyShare ¶
type GPUKeyShare = mpcvm.GPUKeyShare
type GPUMPCVMRoundDescriptor ¶
type GPUMPCVMRoundDescriptor = mpcvm.GPUMPCVMRoundDescriptor
type GPUMPCVMState ¶
type GPUMPCVMState = mpcvm.GPUMPCVMState
type GPUMPCVMTransitionResult ¶
type GPUMPCVMTransitionResult = mpcvm.GPUMPCVMTransitionResult
