INT is the world's first bottom up new-generation blockchain of things (BoT) communication standard and base application platform. The ecosystem is specifically designed for easy integration with any IoT protocol.
To both improve and encourage device interconnectivity, we have built an economy driven ecosystem by providing token-incentives through a decentralized TCP/IP based architecture of IoT. This new business model, molded by IoT devices, will support an entirely new ecosystem of the Internet of Things.
The latest INTChain version for Testnet is v4.0.01
Go 1.12.5+ is required for building and installing the INTChain software.
Install Go by following the official docs.
Remember to set your $GOPATH, $GOBIN, and $PATH environment variables, for example:
mkdir -p $HOME/go/bin
echo "export GOPATH=$HOME/go" >> ~/.bashrc
echo "export GOBIN=$GOPATH/bin" >> ~/.bashrc
echo "export PATH=$PATH:$GOBIN" >> ~/.bashrc
source ~/.bashrcVerify that Go has been installed successfully
go versionYou can install C compiler by your favourite package manager.
After setting up Go and C compiler correctly, you should be able to compile and run intchain.
Make sure that your server can access to google.com because our project depends on some libraries provided by google. (If you are not able to access google.com, you can also try to add a proxy: export GOPROXY=https://goproxy.io)
git clone --branch v4.0.01 https://github.com/intfoundation/intchain
cd intchain
make intchainIf your environment variables have set up correctly, you should not get any errors by running the above commands.
Now check your intchain version.
./bin/intchain versionintchain is the entry point into the INTChain network(main, test or private network). It can be used by other processes as a gateway into the INTChain network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports.
We've enumerated a few common command to let you run your own intchain instance quickly. If you want to look over all command line options, please use intchain --help
The most common condition is that users want to simply interact with the INTChain network: create accounts; transfer funds; deploy and interact with contracts.
./bin/intchain Then you can attach to an already running intchain instance with intchain attach, and you can invoke all official methods.
./bin/intchain attach <datadir>/intchain/intchain.ipcFor developers, you would like to deploy contracts for testing, but you do not want to do that with real money spending. In other words, instead of attaching to the main network, you want to join the test network with your node, which is fully equivalent to the main network.
./bin/intchain --testnetSpecifying the --testnet flag, will reconfigure intchain instance a bit:
- Instead of using the default data directory(
~/.intchain/intchainon Linux for example),intchainwill usetestnet(~/.intchain/testneton Linux). This means that attaching to a running testnet node requires the use of a custom endpoint(intchain attach <datadir>/testnet/intchain.ipc). - The client will connect to the test network, which uses different bootnodes, different network IDs and genesis file.
Starting your own private network is easy with init command method.
First, you need to create the genesis state of your network, which all nodes need to be award of and agree upon.
Init int genesis file and genesis validator
./bin/intchain --datadir <some directory> init_int_genesis "{799600000000000000000000000, 400000000000000000000000}"Init genesis file
./bin/intchain --datadir <some directory> init <datadir>/intchain/int_genesis.jsonStarting up a validator node with the genesis state.
./bin/intchain --datadir <some directory>Starting up a full node with the same genesis state without priv_validator.json file.
./bin/intchain --datadir <other custom data directory> --bootnodes=<validator node bootnode url above>You can create a new wallet, then get some INT from the exchanges or anywhere else into the wallet you just created, .e.g.
# create a new wallet
intchain account newOnce you generate a private validator, it will create a json file priv_validator.json under datadir and restart intchain.
intchain gen_priv_validator <address>intchain attach <datadir>/intchain/intchain.ipc
>int.blockNumberINTChain is a blockchain system based on IPBFT consensus mechanism, which requires regular replacement of validators to ensure system security.
Epoch is the update cycle of the validator, which is about 2 hours.
You can apply candidate to become a candidate.
