In today's rapidly evolving blockchain technology landscape, the reliance of decentralized applications (dApps) on real-world data has evolved from 'nice to have' to 'indispensable'. However, the oracle problem acts as an invisible barrier, separating on-chain smart contracts from the off-chain data world. Orally was born — — this full-chain oracle network built on the Internet Computer Protocol (ICP) is redefining decentralized data services with its modular architecture, multi-chain compatibility, and data immutability.

One, Modular Architecture: Mythical Technology Matrix

Orally's five core modules, inspired by ancient Greek mythology, construct a technological matrix covering the entire data lifecycle:

  1. Sybil (Sybil Oracle)
    As a data aggregation hub, Sybil obtains data from hundreds of embedded price sources (covering cryptocurrencies, stocks, and commodities) through the decentralized consensus mechanism of ICP nodes. Its uniqueness lies in supportingcustom data source expansion — — Developers can freely access weather APIs, sports event data, or even AI model output. All data is signed via DKG (Distributed Key Generation) wallets, providing cryptographic assurance for cross-chain verification.

  2. Pythia (Delphic Oracle)
    An automated data engine that supports triggering data pushes at time intervals (e.g., every hour) or volatility thresholds (e.g., 5% change in ETH price). For example, DeFi protocols can set 'auto-liquidate when BTC price drops below $30k', while GameFi projects can call its BLS signature-based true random number generation function to ensure fairness in loot drop mechanisms.

  3. Apollo (Messenger of the Sun)
    A real-time response system for EVM chains. When a smart contract initiates a data request, Apollo coordinates Sybil to complete data fetching through ICP smart contracts and calls the fulfillData method on the target chain to complete the callback. Its subscription-based billing model is particularly suitable for high-frequency scenarios such as dynamic NFT metadata updates.

  4. Hephaestus (God of Fire and Forge)
    A data preprocessing hub that allows developers to upload custom algorithms written in Rust. For example, converting raw price data into moving averages or merging multiple social media sentiment indicators to generate a composite index. Verified algorithms will be automatically compiled into dedicated smart contracts, seamlessly connecting with Sybil.

  5. Hermes (Messenger of the Gods)
    A cross-chain communication protocol that uses chain key signing technology to achieve message passing between EVM chains. Its innovativeGas optimization algorithmcan reduce the cost of DEX calls on the Polygon chain to Ethereum chain data by 62%, providing infrastructure for multi-chain DeFi composability.

Two, Cracking the Oracle's Century-Old Problem

Orally completely solves the pain points of traditional oracles through a triple mechanism:

  1. Data Authenticity
    Each data packet is accompanied by an ECDSA threshold signature, distributedly generated by ICP subnet nodes. Even if 1/3 of the nodes are attacked, the signature process can still operate normally, eliminating the possibility of single-point tampering.

  2. Anti-Freezing Mechanism
    Real-time detection of data source status through a 'heartbeat monitoring system'. When the main API fails, the system automatically switches to a backup source within 3 block cycles and triggers on-chain audit records. Tests show that during simulated regional failures of Amazon AWS, Sybil maintained 99.97% data availability.

  3. Cost Revolution
    Utilizing ICP's HTTPS Outcall feature to directly access traditional Web APIs reduces data acquisition costs by 80% compared to traditional oracle middleware solutions. The Exchange Rate Canister (XRC) module has achieved full on-chain foreign exchange rate aggregation, consuming only 0.0001 ICP for a single data request.

Three, Practical Scenarios: From DeFi to the Metaverse

Orally's modular design showcases amazing potential in multiple fields:

  • Dynamic NFT Revolution
    A digital art platform integrates NASA solar wind data via Sybil, allowing NFT visuals to change in real-time with cosmic ray intensity. The Hephaestus preprocessing module converts raw data into 256-level color parameters, while Pythia triggers metadata updates every 15 minutes.

  • Insurance Protocol Automation
    An agricultural insurance dApp in Africa integrates satellite weather data; when Sybil detects continuous rainfall below 10mm for 15 days, Pythia automatically triggers insurance payouts, reducing claim processing time from 45 days to 9 minutes.

  • Cross-Chain Liquidity Management
    A DEX aggregator utilizes the Hermes module to synchronize liquidity depth data across 7 EVM chains in real-time. When the ETH/USDC price spread on the Avalanche chain falls below 0.3%, it automatically triggers cross-chain arbitrage instructions.

  • Metaverse Infrastructure
    GameFi projects request 3D scene descriptions generated by off-chain AI servers through Apollo, while Hermes transmits the data across chains to the NFT minting contract on the Flow chain, enabling cross-chain metaverse asset generation.

Four, ICP Technology Foundation

Orally's technical advantages stem from the deep integration of ICP's underlying capabilities:

  • Random Number Beacon
    Based on ICP's 'Random Tape' technology, each block generates unpredictable BLS signatures, providing Pythia with a true random number source that meets NIST standards.

  • Chain Key Revolution
    ECDSA threshold signatures allow a single Canister smart contract to manage cross-chain addresses, enabling the Hermes module to achieve multi-chain private key management without third-party custody.

  • Deterministic Execution
    The ICP timer system ensures that Sybil data updates, Pythia-triggered events, and other operations are completed within a 900ms cycle for global node synchronization, preventing MEV attacks.

Five, Security as a Service

Orally has built a five-dimensional defense system:

  1. Data Source Layer: Multi-source comparison + Outlier removal algorithms

  2. Transmission Layer: TLS 1.3 encryption + IPFS fragmentation storage

  3. Consensus Layer: Asynchronous BFT consensus of ICP nodes

  4. Signature Layer: Threshold ECDSA signatures

  5. Audit Layer: All data processing records are permanently on-chain

Stress tests show that the system can maintain end-to-end latency below 1.2 seconds while handling 120,000 query requests per second, achieving 100% data consistency.

As the integration of blockchain and the physical world accelerates, Orally is redefining the possibilities of oracles with a full-chain architecture. From precise pulses in DeFi to digital neurons in the metaverse, this network named after myths is weaving a web of data connecting reality and the virtual, the present and the future. When every smart contract can access the torrent of real-world data without boundaries, we are not only welcoming the evolution of technology but also the dawn of a new digital civilization era that is open and interconnected.
