## Installation

```
pip install chainlogger
```

After installing via pip, you can include the Chain Logger on your projects as following

```python
import chainlogger as Logger

logger = Logger()
logger.set_provider('YOUR_PROVIDER_URL')
logger.set_abi('CONTRACT_ABI')
logger.set_eth_signer('YOUR_ETH_SIGNER_PROVIDER')
logger.set_contract('CONTRACT_ADDRESS')
logger.set_send_contract('CONTRACT_ADDRESS')
logger.set_web3()
logger.set_salt("MY_SECRET_SALT")
logger.set_account('YOUR_WALLET_ADDRESS')
```

## Registering vendor

```python
logger.register_vendor()

#Returns the txHash of the call
```

## Registering project

```python
logger.register_project()

#Returns the txHash of the call
```

## Registering a log

```python
logger.register_log(project_id, raw_data);

#Returns the txHash of the call
```

## Getting tx receipt for registerLog method

```python
logger.get_transaction_receipt(tx_id);
```

## Verifying data from blockchain

```python
logger.verify_data(hashed_data_from_blockchain, raw_input, salt)

#Returns boolean
```
