Verify() checked the signature against a.GroupPubKey — a field of the very struct being verified. That answers "was this signed by whoever signed it", which every attestation satisfies, including one an attacker minted with its own key and shipped alongside. B-Chain called it immediately before releasing funds, so a self-consistent forgery passed the one check standing between a request and a real transfer. The expected key is an argument now, because it is the whole check: a signature is evidence only when the verifier already knows whose signature it will accept. The caller has it — B-Chain holds the group public point from M-Chain's keygen and never holds a custody secret. A nil or empty expected key fails closed, which is the state of a chain whose keygen has not completed, and exactly when releasing funds would be worst. The attestation still carries its own key so a holder can see which group signed, but a disagreement with the key we trust is a refusal, not a preference for theirs.

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. |
