In the wave of rapid evolution of blockchain technology, the potential of decentralized applications (dApps) is limited by a fundamental challenge — how to safely and efficiently obtain real-world data off-chain. Traditional oracle solutions often struggle to meet demands due to centralization risks, data latency, or high costs, while Orally, based on a full-chain architecture, redefines the possibilities of decentralized oracles through modular design and deep integration with the ICP ecosystem.
Core Challenges and Orally's Solutions.
The closed nature of blockchain prevents it from actively obtaining off-chain data, while traditional oracle's single-point dependency may pose systemic risks. Orally addresses this 'oracle dilemma' through the following innovations:
Decentralized Data Aggregation: Multi-node consensus mechanism ensures the diversity and authenticity of data sources.
Zero Trust Verification: Based on ECDSA threshold signatures and Distributed Key Generation (DKG), the data signing process is completely decentralized, eliminating single-point control.
Dynamic Response: Achieved real-time data updates and anomaly alerts through ICP's random number generation (Random Tape) and heartbeat monitoring (Heartbeat System).
This technical framework not only addresses the 'data credibility' issue but also provides flexible support for different scenarios through modular design.
Six Core Modules: A complete link from data to action.
Orally's architecture consists of six functional modules, each named after a mythological character, symbolizing its unique mission:
Sybil (Data Oracle)
Functionality: Aggregates multi-source off-chain data (prices, weather, event results, etc.), directly connects to Web2 APIs through HTTP Outcalls, and verifies data authenticity with ICP node consensus.
Technical Highlights: Supports custom data sources, allowing developers to build exclusive data streams; DKG signatures ensure data integrity and provide on-chain verification proof via HTTP gateways.
Use Cases: Real-time price updates for DeFi platforms, dynamic NFTs adjusting attributes based on weather changes.
Pythia (Automation Engine)
Functionality: Trigger on-chain operations based on time or volatility conditions (e.g., automatic liquidation of collateral when price fluctuations reach a threshold).
Technical Highlights: Integrates Sybil data stream with ICP random number generator, supporting cross-chain automated tasks, and pays on demand to reduce Gas costs.
Use Cases: GameFi random drop mechanism, conditional liquidation of DeFi protocols.
Apollo (Request Responder)
Functionality: Provides on-demand data calling services for EVM contracts, supporting instant data queries and BLS random number generation.
Technical Highlights: Subscription-based billing model, data is efficiently transmitted via cross-chain messaging protocols (e.g., Hermes) after being pre-processed by Sybil.
Use Cases: Real-time disaster data underwriting for insurance contracts, predicting market outcome assessments.
Hephaestus (Data Forging Factory)
Functionality: Allows developers to upload Rust code for secondary processing of raw data (e.g., calculating financial metrics, filtering outliers).
Technical Highlights: Algorithms are automatically compiled into independent smart contracts, seamlessly integrated with Sybil, outputting structured data directly for dApp use.
Use Cases: Dynamic NFT attribute generation, DAO governance metric calculation.
Hermes (Cross-chain Messenger)
Functionality: Optimizes communication costs across multiple chains, supporting event triggers and data broadcasting.
Technical Highlights: Based on ICP chain key technology, achieving fully decentralized cross-chain signature verification without relying on third-party relays.
Use Cases: Cross-chain DEX liquidity synchronization, multi-chain DAO governance voting.
Cassandra (Decentralized Identity Verification)
Functionality: Log in to dApp using Web2 social accounts to generate on-chain identity credentials.
Technical Highlights: Zero-knowledge verification protects user privacy, credentials can be reused across dApps, lowering the user entry threshold.
Use Cases: DeFi social entry, building a chain game account system.
Empowered by ICP Technology: The cornerstone of the full-chain architecture.
Orally's underlying capabilities deeply integrate ICP protocol features:
ECDSA Threshold Signatures: Achieve cross-chain transaction signing through distributed key management, compatible with mainstream chains like Bitcoin and Ethereum.
HTTPS Outcalls: Directly calls Web2 API data, filtering out anomalous results through multi-node consensus (e.g., exchange rate Canister removes outliers to return the median).
Heartbeat System and Random Number: ICP execution layer timer ensures service stability, BLS signatures generate unpredictable random numbers to meet fairness requirements.
These features enable Orally to operate in a fully 'chainified' manner without relying on external validators, balancing security and economy.
From Concept to Implementation: The diverse application scenarios of Orally.
DeFi Infrastructure
Lending protocols obtain real-time collateral prices through Sybil, triggering automatic liquidation with Pythia to avoid risks of human intervention.
DEX uses exchange rate Canister to compare off-chain market data, preventing price manipulation.
Next Generation GameFi
Hephaestus processes in-game economic data, combining Apollo's random number generation for rare items, ensuring transparency and credibility of results.
Hermes enables multi-chain asset interoperability, allowing players to transfer NFT equipment across chains.
On-chain of physical assets
Real estate tokenization platform uses Sybil to access off-chain valuation data, dynamically adjusting Token prices.
Supply chain traceability system calls weather and logistics APIs, recording immutable transfer information.
Innovative Insurance Model
Crop insurance automatically compensates based on Sybil's weather data, Hephaestus calculates disaster impact indices, reducing manual review.
Conclusion: Redefining the flow of data value
Orally is not just a simple data pipeline, but has built a decentralized data ecosystem: from multi-source collection, trusted verification, intelligent processing to cross-chain access, each link is achieved through modular design for flexible combinations. This architecture not only solves historical problems in the oracle field but also opens up a new dimension for dApps to interact with the real world — whether it's the rapidly changing financial market or dynamic events in the physical world, all can be converted into on-chain programmable trigger conditions. Supported by ICP technology, Orally is becoming a key hub for the integration of Web3 and Web2, enabling blockchain to truly 'sense' reality and unleash the infinite potential of decentralized applications.
