VM consolidation (one module, one place only):
- Removed per-VM go.mod/go.sum/VERSION from {aivm,bridgevm,dexvm,evm,
graphvm,identityvm,keyvm,oraclevm,quantumvm,relayvm,thresholdvm,zkvm}
- All VMs now compile under github.com/luxfi/chains root module
- aivm/, dexvm/, identityvm/, keyvm/, oraclevm/ factory.go + vm.go updated
for AccelHost wiring
cevm Go-side (evm/cevm/):
- cevm.go, cevm_cgo.go, cevm_nocgo.go: ExecuteBlockV4(backend, threads,
txs, ctx, state) with StateAccount snapshot
- cevm_secp256k1.go: BatchRecoverSenders Metal LDFLAGS
- cevm_secp256k1_metal_anchor_darwin.{c,go}: anchor to keep linker from
dropping libsecp256k1_metal.a
- cevm_secp256k1_nocgo.go: stub for non-cgo builds
- plugin.go, fetch-luxcpp.sh, luxcpp-SHA256SUMS, LUXCPP_VERSION:
pinned luxcpp consumption
- evm/cevm/parallel/parallel.go: BlockExecutor adapter calls
cevm.ExecuteBlockV4 with state snapshot built from txs+statedb
Quantum/ZK witness:
- quantumvm/quasar_witness.go, zkvm/zwitness.go
go.mod: removed dead `replace github.com/ethereum/go-ethereum => luxfi/geth`
directive (caused dual-path conflict after math semver bump; no remaining
ethereum/go-ethereum imports in source). go mod tidy clean.
Tests: TestBatchRecoverSenders PASS through Metal anchor (cevm package).

# fetch-luxcpp.sh — download pre-built luxcpp libs so external Go consumers
|
|
# can `go build` this package without a local luxcpp source checkout.
|
|
#
|
|
# Mirrors the layout assumed by cevm_cgo.go:
|
|
# ${SRCDIR}/../../../../luxcpp/cevm/lib/evm/gpu/ (headers)
|
|
# ${SRCDIR}/../../../../luxcpp/cevm/build/lib/ (libevm.*)
|
|
# ${SRCDIR}/../../../../luxcpp/cevm/build/lib/evm/ (libevm-gpu.*)
|

# ${SRCDIR}/../../../../luxcpp/cevm/build/lib/evm/luxcpp-gpu (libluxgpu.*)
|
|
# ${SRCDIR}/../../../../luxcpp/cevm/build/lib/cevm_precompiles
|
|
#
|
|
# In a source-tree build (~/work/lux/chains/evm/cevm/) ${SRCDIR}/../../../../
|
|
# resolves to ~/work/, so the libs live at ~/work/luxcpp/.
|
|
# In a module-cache build it resolves to $GOMODCACHE/github.com/luxfi/, so the
|
|
# libs must live at $GOMODCACHE/github.com/luxfi/luxcpp/. This script targets
|
|
# whichever location is "above" $SRCDIR.
|
|
#
|
|
# Idempotent: skips when libs already present.

|
# Verified: SHA-256 pinned in luxcpp-SHA256SUMS next to this script.

# Usage: ./fetch-luxcpp.sh
|

# Env:

# LUXCPP_VERSION — override version (default: contents of ./LUXCPP_VERSION)

This usually means the luxcpp release tarball for $PLATFORM-$ARCH is not

yet published. Workarounds:
|
|
1. Build from source: clone github.com/luxfi/luxcpp into $TARGET and
|
|
run its CMake build (see luxcpp/cevm/README.md).
|
|
2. Set LUXCPP_VERSION to a known-published tag.
