AI Oracles in Blockchain, an Introduction
Imagine if smart contracts could perceive and interpret real-world events. That’s the potential unlocked by AI oracles.
Smart contracts, by nature, are limited—they can’t access external data or perform sophisticated computations. AI oracles serve as a connection between blockchain and the ever-changing, data-rich world beyond it.
The Oracle Problem in Blockchain
Smart contracts operate in isolated environments and can’t access external data like stock prices, weather conditions, or sports results. This restriction is called the ‘Oracle Problem’ and limits their use.
For instance, a smart contract set to release funds upon the arrival of a shipment would be useless without an oracle to track the shipment’s status.
AI oracles solve this by securely providing external data and computations to smart contracts. They act as intermediaries, collecting, validating, and delivering real-world data to the blockchain in a format that smart contracts can understand, enabling them to respond to real-world events.
Core Components of an AI Oracle
AI oracles consist of several crucial parts:
- Data sources: AI oracles pull data from multiple sources, like APIs, sensors, or other blockchains, depending on the application.
- Data aggregation and validation: Since relying on a single source can be unreliable, AI oracles combine data from various sources and validate it using methods like:
- Consensus mechanisms: Multiple oracles validate data independently, agreeing on its accuracy.
- Reputation systems: More trustworthy oracles are given higher ratings.
- Machine learning: Algorithms detect anomalies in the data.
- Verification layer: Cryptographic techniques ensure the data sent to the blockchain is secure and unaltered.
- Compute-enabled layer: AI oracles can process data off-chain, performing analyses or running AI models before passing the data to smart contracts.
- API interfaces: AI oracles offer secure APIs that let smart contracts access data or computations, enabling smooth interaction with the blockchain. With built-in dashboards and tools, developers can easily manage oracles, configure data feeds, and monitor performance.
- Blockchain integration: AI oracles securely write validated data onto the blockchain, ensuring it is accessible for triggering actions in smart contracts.
AI Oracle Designs
AI oracles come in different forms, each with its pros and cons:
- Centralised oracles: Controlled by one entity, they are simple but vulnerable to single points of failure.
- Decentralised oracles: Spread trust among many independent operators, making them more secure but also more complex.
- Hybrid oracles: These combine aspects of centralised and decentralised models, balancing efficiency and security.
Why AI Oracles Are Key to Blockchain’s Future
AI oracles greatly expand the capabilities of smart contracts by allowing them to access real-world data. This improves automation, trust, and transparency, and opens the door for innovative decentralised applications (dApps) across industries.
Example: AI Oracle in Supply Chain Management
AI oracles can provide real-time, verifiable data about goods in transit. For example, with perishable goods, IoT sensors in shipping containers can continuously monitor conditions. AI oracles collect this data and feed it to smart contracts. If conditions deviate, the smart contract can trigger alerts or even take corrective actions, like adjusting refrigeration.
This leads to several benefits: Improved product quality and safety, enhanced traceability, reduced fraud, and increased efficiency and cost savings.
AI Oracles in aelf
The AI-centric blockchain platform aelf integrates AI into its core framework. In 2025, aelf plans to introduce AI oracles, focusing not only on securing AI computations but also on ensuring that higher-level AI applications and data sources remain trustworthy.
Steps in aelf’s AI Oracle Implementation
- On-chain components: The on-chain components will reside on the aelf blockchain (with potential future deployment on other chains like Ethereum). including systems for managing nodes, tracking reputation, settling costs, and deploying AI services efficiently.
- Off-chain components: Using technologies like TLS Notary and Intel’s SGX, aelf will ensure secure, untampered data processing and communication within AI services.
Developer Tools for AI Oracles
aelf aims to make it easy for developers to use AI oracles by offering tools and frameworks to automate oracle generation and interaction. For simple AI tasks, much of the process will be automated, but more complex services will require developer input.
Conclusion
As blockchain technology advances, AI oracles will become increasingly important, bridging the gap between on-chain and off-chain data. Platforms like aelf demonstrate AI and blockchain interoperability, offering new possibilities for innovation while ensuring data integrity and trust.
