zeekayandHanzo Dev 85e1287852 mpcvm: an ownership claim is a signed fact about a token, not a copy of it
An entitlement-gated chain needs a credential its operator cannot forge. The
collection that confers the entitlement lives on another chain's EVM, so the
node cannot read it and must not be asked to: a check a node runs against data
its own operator supplies is not a control.

So M threshold-signs the fact instead. chains/ownership is the frozen wire
format both sides share -- the claim's field layout, the domain tag, the signed
payload, and one verification entry point. It is dependency-free and
non-internal because the verifier is a node in another module that must never
link the M-Chain VM.

Authorizes answers authenticity and node-binding together. There is no exported
way to ask only one, because a caller that checked the signature and forgot the
binding would let any node activate on a peer's entitlement.

The domain registers additively, reusing ComputeAttestationPayload rather than
defining a parallel digest, so equivocation detection and quorum verification
already apply. The claim's block is the epoch, which makes two facts about one
node at one block contradictory while re-attesting later is how ownership moves.

KAT vectors freeze the bytes; a test asserts M's payload and the verifier's are
byte-identical, since nothing else forces those two functions to agree.

Lux Chains

Independent VM plugin binaries for the Lux Network.

Each directory builds to a standalone binary that the Lux node loads as a plugin via --plugin-dir.

Build

make            # build all VMs
make evm        # build one VM
make test       # test all

Install

lpm install evm
lpm install dexvm

Or copy binaries to ~/.lux/plugins/<vmid>.

VMs

One row per directory in this repo. make derives its target list from the directory listing, so a VM that has no directory here has no binary — the table below and ls can never disagree.

Live means the VM has a chain registered on Lux mainnet 96369 (platform.getBlockchains).

VM Chain Live on 96369 Purpose
evm C-Chain ✅ EVM smart contracts
dexvm D-Chain ✅ Decentralized exchange
aivm A-Chain ✅ AI/ML inference
bridgevm B-Chain ✅ Cross-chain bridge — also owns all cross-chain messaging / relay / teleport (LP-6000); there is no separate teleportvm
graphvm G-Chain ✅ GraphQL data layer
keyvm K-Chain ✅ Key management
quantumvm Q-Chain ✅ Post-quantum consensus signing (Pulsar)
zkvm Z-Chain ✅ Groth16 over BLS12-381 (rolls N × ML-DSA-65 sigs into 192-byte proof)
identityvm I-Chain ❌ built, not deployed Decentralized identity
oraclevm O-Chain ❌ built, not deployed Oracle/off-chain data
relayvm R-Chain ❌ built, not deployed Cross-chain relay
mpcvm M-Chain ❌ built, not deployed MPC ceremonies (CGGMP21, FROST, Pulsar-general) — bridge custody for external wallets (LP-7100)
schain S-Chain ❌ built, not deployed S3-style object storage (on-chain metadata / off-chain blob). Declares its own VMID = ids.ID{'s','c','h','a','i','n'} in schain/factory.go and is not in the canonical luxfi/constants VM-ID registry

P-Chain (platformvm) and X-Chain (xvm) are in-process core VMs registered by luxfi/node, not plugins built here. Together with the eight ✅ rows above they are the ten chains live on 96369.

Not in this repo

Name Status
teleportvm / T-Chain Removed. LP-134 dissolves T-Chain with zero remainder: threshold signing → M-Chain, FHE → F-Chain, cross-chain messaging/teleport → B-Chain (bridgevm). LP-5013 and LP-7330 are deprecated by LP-134; see LP-7050 for the migration map. No teleportvm VM ID exists in luxfi/constants.
servicenodevm Never existed. The service-node registry was never built under this name; the S-Chain directory here is schain/ and is object storage, not a registry.
fhevm / F-Chain Unbuilt. luxfi/constants reserves FHEVMID = {'f','h','e','v','m'} and luxfi/node/node/vms.go lists it in OptionalVMs as a plugin named fhevm, so luxd will scan --plugin-dir for it — but there is no fhevm/ directory in this repo and no plugin binary anywhere, so that scan always comes up empty. The FHE runtime library lives at mpcvm/fhe/; it is a package inside mpcvm, not a standalone chain. F-Chain is a spec (LP-8200, LP-167) with no shipping VM.
