Go Ronin

Official Golang execution layer implementation of the Ronin protocol. It is a fork of Go Ethereum - https://github.com/ethereum/go-ethereum and EVM compatible.

Ronin consensus uses Proof of Staked Authority, a combination of dPoS and PoA, to increase the level of decentralization and allows the token holders to join the network as validators

Check out the whitepaper for more information.

Executables

The go-ethereum project comes with several wrappers/executables found in the cmd directory.

Command	Description
ronin	Our main Ronin CLI client. It is the entry point into the Ronin network (main-, test- or private net), capable of running as a full node (default), archive node (retaining all historical state) or a light node (retrieving data live). It can be used by other processes as a gateway into the Ronin network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. ronin --help and the CLI page for command line options.
clef	Stand-alone signing tool, which can be used as a backend signer for ronin.
devp2p	Utilities to interact with nodes on the networking layer, without running a full blockchain.
abigen	Source code generator to convert Ethereum contract definitions into easy to use, compile-time type-safe Go packages. It operates on plain Ethereum contract ABIs with expanded functionality if the contract bytecode is also available. However, it also accepts Solidity source files, making development much more streamlined. Please see our Native DApps page for details.
bootnode	Stripped down version of our Ethereum client implementation that only takes part in the network node discovery protocol, but does not run any of the higher level application protocols. It can be used as a lightweight bootstrap node to aid in finding peers in private networks.
evm	Developer utility version of the EVM (Ethereum Virtual Machine) that is capable of running bytecode snippets within a configurable environment and execution mode. Its purpose is to allow isolated, fine-grained debugging of EVM opcodes (e.g. evm --code 60ff60ff --debug run).
rlpdump	Developer utility tool to convert binary RLP (Recursive Length Prefix) dumps (data encoding used by the Ethereum protocol both network as well as consensus wise) to user-friendlier hierarchical representation (e.g. rlpdump --hex CE0183FFFFFFC4C304050583616263).
puppeth	a CLI wizard that aids in creating a new Ethereum network.

Running ronin

Going through all the possible command line flags is out of scope here (please consult our CLI Wiki page), but we've enumerated a few common parameter combos to get you up to speed quickly on how you can run your own geth instance.

Requirements

Running a full Ronin node:

• CPU: Equivalent of 8 AWS vCPU
• RAM: 16GB
• Storage: At least 1 TB high-speed SSD
• Network: Reliable IPv4 or IPv6 network connection, with an open public port

Running an archive Ronin node:

• CPU: Equivalent of 8 AWS vCPU
• RAM: 16GB
• Storage: At least 5 TB high-speed SSD
• Network: Reliable IPv4 or IPv6 network connection, with an open public port

Building the source

Building ronin requires both a Go (version 1.17 or later) and a C compiler. You can install them using your favourite package manager. Once the dependencies are installed, run

make ronin

or, to build the full suite of utilities:

make all

Init genesis

Before running a full node, init genesis block is necessary

ronin init genesis/mainnet.json --datadir /opt/ronin

Full node on the main Ronin network

$ ronin --http.api eth,net,web3,consortium --networkid 2020 --discovery.dns enrtree://AIGOFYDZH6BGVVALVJLRPHSOYJ434MPFVVQFXJDXHW5ZYORPTGKUI@nodes.roninchain.com --datadir /opt/ronin --port 30303 --http --http.corsdomain '*' --http.addr 0.0.0.0 --http.port 8545 --http.vhosts '*' --ws --ws.addr 0.0.0.0 --ws.port 8546 --ws.origins '*' 

This command will:

• Start ronin in full sync mode (default, can be changed with the --syncmode flag), causing it to download more data in exchange for avoiding processing the entire history of the Ronin network, which is very CPU intensive.

Configuration

As an alternative to passing the numerous flags to the ronin binary, you can also pass a configuration file via:

$ ronin --config /path/to/your_config.toml

To get an idea of how the file should look like you can use the dumpconfig subcommand to export your existing configuration:

$ ronin --your-favourite-flags dumpconfig

Programmatically interfacing ronin nodes

As a developer, sooner rather than later you'll want to start interacting with ronin and the Ronin network via your own programs and not manually through the console. To aid this, ronin has built-in support for a JSON-RPC based APIs which are the same as Ethereum that can be found at (standard APIs and ronin specific APIs). These can be exposed via HTTP, WebSockets and IPC (UNIX sockets on UNIX based platforms, and named pipes on Windows).

The IPC interface is enabled by default and exposes all the APIs supported by ronin, whereas the HTTP and WS interfaces need to manually be enabled and only expose a subset of APIs due to security reasons. These can be turned on/off and configured as you'd expect.

HTTP based JSON-RPC API options:

• --http Enable the HTTP-RPC server
• --http.addr HTTP-RPC server listening interface (default: localhost)
• --http.port HTTP-RPC server listening port (default: 8545)
• --http.api API's offered over the HTTP-RPC interface (default: eth,net,web3)
• --http.corsdomain Comma separated list of domains from which to accept cross origin requests (browser enforced)
• --ws Enable the WS-RPC server
• --ws.addr WS-RPC server listening interface (default: localhost)
• --ws.port WS-RPC server listening port (default: 8546)
• --ws.api API's offered over the WS-RPC interface (default: eth,net,web3)
• --ws.origins Origins from which to accept websockets requests
• --ipcdisable Disable the IPC-RPC server
• --ipcapi API's offered over the IPC-RPC interface (default: admin,debug,eth,miner,net,personal,shh,txpool,web3)
• --ipcpath Filename for IPC socket/pipe within the datadir (explicit paths escape it)

You'll need to use your own programming environments' capabilities (libraries, tools, etc) to connect via HTTP, WS or IPC to a geth node configured with the above flags and you'll need to speak JSON-RPC on all transports. You can reuse the same connection for multiple requests!

Note: Please understand the security implications of opening up an HTTP/WS based transport before doing so! Hackers on the internet are actively trying to subvert Ethereum nodes with exposed APIs! Further, all browser tabs can access locally running web servers, so malicious web pages could try to subvert locally available APIs!
