# What is
Welcome to Sirio Protocol, the first lending & borrowing platform on Hedera developed by the [Astrid Network](https://www.astrid.network/) team to leverage AI and high-permorning DLT. Sirio was created with the aim of contributing to the growth of the Hedera DeFi ecosystem, ensuring the best user experience for all users thanks to the features of the chain, an advanced experience using AI and a Data-Driven approach. Indeed, Sirio is the first protocol with a Machine Learning algorithm that allows calculating and predicting the liquidation risk associated with a loan, considering dozens of variables. Thanks to our Data-Driven approach, you will be able to see many Global and Individual data related to the protocol activity.
### What can you do on Sirio?
Sirio is a overcollateralized Lending & Borrowing protocol with an architecture inspired by Compound V2. However, we have decided to build it from scratch to ensure greater security, minimizing vulnerabilities. For this reason, the functions you can perform on Sirio are as follows:
* **Supplier:** You can deposit your assets on our platform, earning a passive interest rate. The interest rate is variable and depends on the demand and supply of the asset you deposit. For more information, we invite you to visit the documentation on the [Interest Rate Model](https://astrid.gitbook.io/sirio/architecture/interest-rate-model). Your assets are borrowed by borrowers, who will pay interest on them. You don't have to worry about the insolvency of borrowers: the assets that are borrowed are secured by the collateral they deposit.
* **Borrowers:** If you deposit assets (following the same procedures as suppliers), the value of these assets will make you eligible to borrow other assets. You can borrow assets for various reasons: to go long or short on a token listed on Sirio, to exploit arbitrage opportunities, to invest in a token in the short term without giving up your long-term investments.
* **Liquidators:** It can happen that loans are at risk of being under-collateralized. To ensure the integrity of the protocol and the safety of supplier funds, Sirio uses a liquidation mechanism, wherein, when a borrower is close to insolvency, a liquidator can repay a debt and receive a reward. For more information, you can visit the [Liquidation section](https://astrid.gitbook.io/sirio/architecture/liquidation-mechanism).
Ultimately, this is the flowchart behind the logic of our protocol:
