zeekay 0ff6430a7b bridgevm: a transfer is released only once its block is durable
Accept credited the daily volume, completed the requests, advanced
lastAcceptedID, dropped the block from the in-flight set and handed the
transfers to the release worker — which broadcasts on an external chain — and
only then wrote the block. Every one of those survived a failed write, so a
release could be in flight for a transfer no block records.

lastAcceptedID was never written at all. The tip lived in memory, reset to
genesis on every restart, and the daily volume that bounds the bridge limit
went with it.

The block now commits through the shared store, which writes it with its height
entry and the tip in one batch, and its effects — including the handoff to the
release worker — happen only afterwards. A proposal follows the engine's
preference, which the store now holds, rather than always the accepted tip.

The bridge's own state keeps its own lock. The transfers in flight, the signer
set, the chain clients and the release plumbing are not the chain's state, and
folding them into the chain's lock would say they were. The order is the
chain's lock, then the bridge's, then the registry's, and it is written down
where the locks are.

Still in memory only, and NOT changed here because it needs its own design: the
completed-bridge registry and the daily volume. A restart still forgets both,
which re-opens the daily bridge limit.

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

make's target list is named in the Makefile, and every name in it is a directory here that ships a plugin entrypoint (<vm>/cmd/plugin, or evm/main.go). dexvm/ is the exception in the table below: it is a library the EVM plugin embeds — it has no entrypoint of its own, so make builds no dexvm binary. The other directories here (fee/, ownership/, internal/, cmd/) are libraries and a tool, and are not VMs.

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)
fhevm F-Chain ❌ built, not deployed Confidential compute (LP-8200): ciphertext handles, access permits, threshold decryption. Records the public coordinates of encrypted values and holds none of the encrypted part — no ciphertext body, no FHE key, no share. Wraps the FHE runtime at mpcvm/fhe/
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.

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.

Plugin filenames

luxd resolves a CreateChainTx's vmID to an implementation by looking for a file of that name in --plugin-dir, so a plugin installed under any other name is invisible and its chain silently never starts. The filename is the CB58 of the vmID — n6sSsSfbpQBrU9sY4R29U6z8VrmnTo2CntW6da4rRS7qmnGdv for fhevm, qCURact1n41FcoNBch8iMVBwc9AWie48D118ZNJ5tBdWrvryS for mpcvm. Each VM pins its own in a test, because a vmID cannot change once a chain has been created with it.
