EVM-compatible chain secured by the Lachesis consensus algorithm.
Node with implemented OpenEthereum(Parity) transaction tracing API.
make galaxy
The build output is build/galaxy
executable.
Going through all the possible command line flags is out of scope here,
but we've enumerated a few common parameter combos to get you up to speed quickly
on how you can run your own galaxy
instance.
Before first launching of your mainnet node you will need appropriate genesis file:
wget https://github.com/Flag-Blockchain/chain-binary/raw/master/mainnet.g
Or for testnet node:
wget https://github.com/Flag-Blockchain/chain-binary/raw/master/testnet.g
Launching galaxy
readonly (non-validator) node for network specified by the genesis file:
$ galaxy --genesis mainnet.g
As an alternative to passing the numerous flags to the galaxy
binary, you can also pass a
configuration file via:
$ galaxy --config /path/to/your_config.toml
To get an idea how the file should look like you can use the dumpconfig
subcommand to
export your existing configuration:
$ galaxy --your-favourite-flags dumpconfig
New validator private key may be created with galaxy validator new
command.
To launch a validator, you have to use --validator.id
and --validator.pubkey
flags to enable events emitter.
$ galaxy --nousb --validator.id YOUR_ID --validator.pubkey 0xYOUR_PUBKEY
galaxy
will prompt you for a password to decrypt your validator private key. Optionally, you can
specify password with a file using --validator.password
flag.
This branch is for a transaction tracing node. It's not recommended to use this branch for an Galaxy validator.
trace_get
trace_transaction
trace_block
trace_filter
Building galaxy
requires a Go (version 1.15 or later) and a C compiler. Once the dependencies are installed, run:
make galaxy
The build output is build/galaxy
executable.
It's recommended to launch new node from scratch with CLI option --tracenode
as this flag has to be set to use stored transaction traces.
$ galaxy --genesis /path/to/genesis.g --tracenode
If you want to use tracing for pre-genesis blocks, you'll need to import evm history. You can find instructions here: importing evm history
Then enable JSON-RPC API with option trace
(--http.api=eth,web3,net,txpool,flag,sfc,trace"
)
After that, you have to connect your nodes. Either connect them statically or specify a bootnode:
$ galaxy --fakenet 1/5 --bootnodes "enode://verylonghex@1.2.3.4:5050"
For the testing purposes, the full demo may be launched using:
cd demo/
./start.sh # start the Galaxy processes
./stop.sh # stop the demo
./clean.sh # erase the chain data
