TrueChain Engineering Code

TrueChain is a truly fast, permissionless, secure and scalable public blockchain platform which is supported by hybrid consensus technology called Minerva and a global developer community.    TrueChain uses hybrid consensus combining PBFT and fPoW to solve the biggest problem confronting public blockchain: the contradiction between decentralization and efficiency.

TrueChain uses PBFT as fast-chain to process transactions, and leave the oversight and election of PBFT to the hands of PoW nodes. Besides, TrueChain integrates fruitchain technology into the traditional PoW protocol to become fPoW, to make the chain even more decentralized and fair.

TrueChain also creates a hybrid consensus incentive model and a stable gas fee mechanism to lower the cost for the developers and operators of DApps, and provide better infrastructure for decentralized eco-system. 

Building the source

Building getrue requires both a Go (version 1.14 or later) and a C compiler. You can install them using your favourite package manager. Once the dependencies are installed, run

make getrue

or, to build the full suite of utilities:

make all

The execuable command getrue will be found in the cmd directory.

Running getrue

Going through all the possible command line flags is out of scope here (please consult our CLI Wiki page), also you can quickly run your own getrue instance with a few common parameter combos.

Running on the Truechain main network

$ getrue console

This command will:

• Start getrue with network ID 19330 in full node mode(default, can be changed with the --syncmode flag after version 1.1).
• Start up Getrue's built-in interactive console, (via the trailing console subcommand) through which you can invoke all official web3 methods as well as Geth's own management APIs. This too is optional and if you leave it out you can always attach to an already running Getrue instance with getrue attach.

Running on the Truechain test network

To test your contracts, you can join the test network with your node.

$ getrue --testnet console

The console subcommand has the exact same meaning as above and they are equally useful on the testnet too. Please see above for their explanations if you've skipped here.

Specifying the --testnet flag, however, will reconfigure your Geth instance a bit:

• Test network uses different network ID 18928
• Instead of connecting the main TrueChain network, the client will connect to the test network, which uses testnet P2P bootnodes, and genesis states.

Configuration

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

$ getrue --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:

$ getrue --your-favourite-flags dumpconfig

Running on the Truechain singlenode(private) network

To start a getrue instance for single node, run it with these flags:

$ getrue --singlenode  console

Specifying the --singlenode flag, however, will reconfigure your Geth instance a bit:

• singlenode network uses different network ID 400
• Instead of connecting the main or test TrueChain network, the client has no peers, and generate fast block without committee.

Which will start sending transactions periodly to this node and mining fruits and snail blocks.
