# Basic ETH Price Prediction Node
# Basic Price Prediction Node
This repository provides an example Allora network worker node, designed to offer price predictions for ETH. The primary objective is to demonstrate the use of a basic inference model running within a dedicated container, showcasing its integration with the Allora network infrastructure to contribute valuable inferences.
This repository provides an example Allora network worker node, designed to offer price predictions. The primary objective is to demonstrate the use of a basic inference model running within a dedicated container, showcasing its integration with the Allora network infrastructure to contribute valuable inferences.
## Components
- **Worker**: The node that publishes inferences to the Allora chain.
- **Inference**: A container that conducts inferences, maintains the model state, and responds to internal inference requests via a Flask application. This node operates with a basic linear regression model for price predictions.
- **Updater**: A cron-like container designed to update the inference node's data by daily fetching the latest market information from Binance, ensuring the model stays current with new market trends.
- **Updater**: A cron-like container designed to update the inference node's data by daily fetching the latest market information from the data provider, ensuring the model stays current with new market trends.
Check the `docker-compose.yml` file for the detailed setup of each component.
@ -17,14 +17,45 @@ A complete working example is provided in the `docker-compose.yml` file.
### Steps to Setup
1. **Clone the Repository**
2. **Copy and Populate Configuration**
2. **Copy and Populate Model Configuration environment file**
Copy the example .env.example file and populate it with your variables:
```sh
cp .env.example .env
```
Here are the currently accepted configurations:
- TOKEN
Must be one in ['ETH','SOL','BTC','BNB','ARB'].
Note: if you are using `Binance` as the data provider, any token could be used.
If you are using Coingecko, you should add its `coin_id` in the [token_map here](https://github.com/allora-network/basic-coin-prediction-node/blob/main/updater.py#L107). Find [more info here](https://docs.coingecko.com/reference/simple-price) and the [list here](https://docs.google.com/spreadsheets/d/1wTTuxXt8n9q7C4NDXqQpI3wpKu1_5bGVmP9Xz0XGSyU/edit?usp=sharing).
- TRAINING_DAYS
Must be an `int` >= 1.
Represents how many days of historical data to use.
- TIMEFRAME
This should be in this form: `10m`, `1h`, `1d`, etc.
Note: For Coingecko, Data granularity (candle's body) is automatic - [see here](https://docs.coingecko.com/reference/coins-id-ohlc). To avoid downsampling, it is recommanded to use with Coingecko:
- TIMEFRAME >= 30m if TRAINING_DAYS <= 2
- TIMEFRAME >= 4h if TRAINING_DAYS <= 30
- TIMEFRAME >= 4d if TRAINING_DAYS >= 31
- MODEL
Must be one in ['LinearRegression','SVR','KernelRidge','BayesianRidge'].
You can easily add support for any other models by [adding it here](https://github.com/allora-network/basic-coin-prediction-node/blob/main/model.py#L133).
- REGION
Must be `EU` or `US` - it is used for the Binance API.
- DATA_PROVIDER
Must be `Binance` or `Coingecko`. Feel free to add support for other data providers to personalize your model!
- CG_API_KEY
This is your `Coingecko` API key, if you've set `DATA_PROVIDER=coingecko`.
3. **Copy and Populate Worker Configuration**
Copy the example configuration file and populate it with your variables:
```sh
cp config.example.json config.json
```
3. **Initialize Worker**
4. **Initialize Worker**
Run the following commands from the project's root directory to initialize the worker:
```sh
@ -35,11 +66,11 @@ A complete working example is provided in the `docker-compose.yml` file.
- Automatically create Allora keys for your worker.
- Export the needed variables from the created account to be used by the worker node, bundle them with your provided `config.json`, and pass them to the node as environment variables.
4. **Faucet Your Worker Node**
5. **Faucet Your Worker Node**
You can find the offchain worker node's address in `./worker-data/env_file` under `ALLORA_OFFCHAIN_ACCOUNT_ADDRESS`. [Add faucet funds](https://docs.allora.network/devs/get-started/setup-wallet#add-faucet-funds) to your worker's wallet before starting it.
5. **Start the Services**
6. **Start the Services**
Run the following command to start the worker node, inference, and updater nodes:
