POC for token reward of the voice recording

Before get started

The voice uploaded here is not earning the LANG token.

Install dependencies

For OS X, you can use brew as well

$ apt install nodejs // Recommand nodejs >= 8.x.x
$ npm install truffle ganache-cli -g

Run private blockchain network

There are two alternatives for run the test network.

Use ganache-cli

// Install ganache-cli if you don't have
$ ganache-cli

Use geth

$ cd $PROJECT_PATH

// init the network with genesis block
$ geth init ./genesis.json --datadir geth_data

// Run geth 
$ geth --datadir ./geth_data --networkid 15 --rpc --rpcapi="db,eth,net,web3,personal,web3" --verbosity 3

And open another window, type the following command

$ cd $PROJECT_PATH

// attach to the network
$ geth attach --datadir ./geth_data

// Unlock the first account
> web3.personal.unlockAccount(web3.personal.listAccounts[0], "1234", 15000);

// Start mining
> miner.start()

Run contract test

// Use ganache-cli if you want to test
$ truffle test --network dev

Compile & Migrate

// Compile the contract
$ truffle compile

// Ensure that you ran a geth network with http://localhost:8545 and network id should be 15
// Migrate contract to geth network with password
$ ACCOUNT_PASSWORD=1234 truffle migrate --network geth

Using network 'geth'.
