The primary-network chains answer to either case; one spelling beats two. /v1/chain/c/rpc, /v1/chain/p, /v1/chain/x across the estate. Co-authored-by: Hanzo Dev <[email protected]>

runtime/cpp
A shim. No C++ source lives here — make luxd RUNTIME=cpp configures
~/work/lux-cpp/node into its own build/ and copies the luxd target to
bin/cpp/luxd.
What it builds
A running Lux node: cevm executing C-Chain blocks, BLS quorum-certificate
consensus over a TCP mesh framed by ZAP, and JSON-RPC at /v1/chain/c/rpc.
Every validator executes each block itself and signs the root its own
execution produced, so a certificate is agreement about a result rather than
about a name.
That project also builds other networks' executables from the same source.
This repository builds luxd and names nothing else.
What it resolves
The node's own CMakeLists.txt finds these as siblings and adds them; this
shim does not resolve them a second time.
~/work/lux-cpp/consensus— the consensus engine~/work/luxcpp/cevm— the EVM that executes C-Chain blocks~/work/luxcpp—blst,bls_signature, and the ZAP codec
The build
make luxd RUNTIME=cpp
It needs a Conan toolchain for cevm's dependencies. CONAN_TOOLCHAIN names
it and the Makefile prints the conan install line to write one if it is
missing. Nothing is written back into the checkout except its own gitignored
build/.
Reading a chain back
An RLP export enters two ways — at startup and while the node runs — and both
are the same function, import_chain_data in that repo's src/import.cpp.
bin/cpp/luxd --chain-id 96368 --import-chain-data <file>.rlp
curl -s -X POST -H 'content-type: application/json' \
--data '{"jsonrpc":"2.0","id":1,"method":"admin_importChain","params":["<file>.rlp"]}' \
http://127.0.0.1:<rpc>/v1/chain/c/rpc
After an import the node does not act as a caught-up validator: the outer index is missing, so it refuses to build blocks until that is rebuilt from certified peer state. An import writes inner blocks directly and creates no outer envelope, so every consensus frontier below the imported tip is absent, and a node that proposed on top of it would be signing history it never verified.
