Radix DataFeed
The Morpher DataFeed provides real-time price feeds and market data for blockchain applications on the Radix network. This page introduces the data feed system and its key features.
What is a Blockchain Data Feed?
Blockchain data feeds are services that connect smart contracts with data from the outside world. They act as bridges between blockchains and external systems, allowing smart contracts to access real-world information such as:
- Price data for cryptocurrencies and traditional assets
- Sports results and event outcomes
- Weather data
- Random number generation
- Any other off-chain information
Pull vs Push Data Feed Models
- DApps or Smart contracts actively request data from the data feed
- Data is fetched on-demand
- More control over when and how data is updated
- Better suited for real-time or time-sensitive applications
- Push-based systems proactively send data to smart contracts
- Data is updated at predefined intervals or thresholds
- More efficient for data that changes at known intervals
- Less suitable for immediate or real-time data needs
The Morpher DataFeed Approach
The Morpher DataFeed on Radix is a pull-based data feed. This means:
- Data is fetched off-chain by your application
- The DataFeed signs this data cryptographically
- Users include the signed data in their transaction manifests
- Smart contracts verify the data on-chain using the DataFeed’s public key
This approach offers several advantages:
- Efficiency: Only fetch data when needed
- Cost-effectiveness: No continuous on-chain updates
- Freshness: Always get the latest data at transaction time
- Security: All data is cryptographically signed and verified
Available Networks
The Morpher DataFeed is available on both Radix Mainnet and Stokenet (testnet). For detailed information about network configurations, API endpoints, and component addresses, see the Networks and Endpoints page.
