Travis

The first production version of the CyberMiles blockchain.

You MUST have GO language version 1.9+ installed in order to build and run a Travis node. The easiest way to get GO 1.9 is through the GVM.

bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)
source $HOME/.gvm/scripts/gvm
gvm install go1.9.2 -B
gvm use go1.9.2 --default

Installation

$ go get github.com/CyberMiles/travis
$ cd $GOPATH/src/github.com/CyberMiles/travis
$ git checkout master
$ make all

If the system cannot find glide at the last step, make sure that you have $GOPATH/bin under the $PATH variable.

For example:

export GOPATH=~/.gvm/pkgsets/go1.9.2/global
export GOBIN=$GOPATH/go/bin
export PATH=$GOBIN:$PATH

Initialize a Travis node

$ travis node init --home ~/.travis

Start a Travis node

$ travis node start --home ~/.travis

Start a Travis client and send transactions

$ travis attach http://localhost:8545

personal.unlockAccount("from_address")
cmt.sendTransaction({"from": "from_address", "to": "to_address", "value": web3.toWei(0.001, "cmt")})

Write a script to check all Travis client account balances

The following script can be pasted into the Travis client, at the > prompt.

function checkAllBalances() {
    var totalBal = 0;
    for (var acctNum in cmt.accounts) {
        var acct = cmt.accounts[acctNum];
        var acctBal = web3.fromWei(cmt.getBalance(acct), "cmt");
        totalBal += parseFloat(acctBal);
        console.log("  cmt.accounts[" + acctNum + "]: \t" + acct + " \tbalance: " + acctBal + " CMT");
    }
    console.log("  Total balance: " + totalBal + "CMT");
};

Run the checkAllBalances() script

checkAllBalances();

Example output

> checkAllBalances();
  cmt.accounts[0]: 	0x6....................................230 	balance: 466.798526 CMT
  cmt.accounts[1]: 	0x6....................................244 	balance: 1531 CMT
  Total balance: 1997.798526CMT
