ipfs daemon

Open a terminal and run ganache, use the mnemonic to make default values work. Default connection is localhost:8545.

ganache-cli -m "hamster coin cup brief quote trick stove draft hobby strong caught unable"

Deploy contract on ETH network, standard setting can be found in /contract/truffle-config.js. Default contract address is 0x4d470146215d085c75767b717dbB8D3b4468F893.

cd contract;
truffle migrate --reset

Run Shuttle:

cargo run -- <FILE_NAME>

You can check that the value for the CID has changed by using truffle console query the contract.

➜ truffle console
truffle(development)> const c = await Registry.deployed()
undefined
truffle(development)> await c.getCID()
'QmNYAv3mGTrHS2Jch93JYVSv5yX3EDhvJUNyTYYtdbqgGs'
truffle(development)>

Using ganache-bin Before upload it should be empty on a new contract. After upload the CID should be the entry variable:
