@ -36,47 +36,46 @@ Let's go through each of these in detail.
For now, you're Alice:) Let's proceed.
Run `ganache-cli` locally:
```bash
ganache-cli
```
```javascript
const { Ocean, Logger } = require('@oceanprotocol/lib')
const config={
network: 'rinkeby',
privateKey:'8da4ef21b864d2cc526dbdb2a120bd2874c36c9d0a1fb7f8c63d7f7a8b41de8f',
}
const ocean = Ocean(alice_config)
const account = await ocean.accounts.list()[0]
const myToken = ocean.datatoken.create('localhost:8030',account)
const dt_address=myToken.getAddress()
console.log(dt_address)
const tokenAmount = 100
const transferAmount = 1
const blob = 'http://localhost:8030/api/v1/provider/services'
const alice = await ocean.accounts.list()[0]
const bob = await ocean.accounts.list()[0]
// create datatoken class
const datatoken = new DataTokens(contracts.factoryAddress, factoryABI, datatokensABI, web3)
// deploy datatoken
const tokenAddress = await datatoken.create(blob, alice)
```
## 2. Alice hosts the dataset
A locally providerService is required, which will serve just one file for this demo.
Let's create the file to be shared:
```
touch /var/mydata/myFolder1/file
````
Run the providerService:
(given that ERC20 contract address from the above is 0x1234)
Clone [provider-py](https://github.com/oceanprotocol/provider-py) and update your local environment variables:
```
ENV DT="{'0x1234':'/var/mydata/myFolder1'}"
docker run @oceanprotocol/provider-py -e CONFIG=DT
export PROVIDER_ADDRESS=your_provider_address
export PROVIDER_KEY=your_provider_key
export CONFIG='{"File": "https://raw.githubusercontent.com/oceanprotocol/barge/master/README.md"}'
```
## 3. Alice mints 100 tokens
```javascript
myToken.mint(100)
datatoken.mint(tokenAddress, alice, tokenAmount)
```
## 4. Alice transfers 1 token to Bob
```javascript
myToken.transfer(1,BobAddress)
const ts = await datatoken.transfer(tokenAddress, bob, transferAmount, alice)
const transactionId = ts['transactionHash']
```
## 5. Bob consumes dataset
