# 4. Mining

The CreDA Credit Oracle will rely on three key data streams to compute a user credit rating:

**1.Credit Mining**

* Public on-chain data across the blockchains
* Supports multiple blockchains including Ethereum, Arbitrum, ESC, BSC, HECO, Polygon, etc.
* Platform incentives for end users

**2. Enterprise Mining**

* Non-public on-chain and off-chain data provided by partners
* Incentivize third-party applications that connect with the Credit Oracle

 **3. Verification Mining**

* Validator election to verify on-chain and off-chain data used by the CreDA protocol
* Validator nodes can obtain verification mining rewards
