Decentralized Oracle Redundancy System (DORS)

A robust and secure decentralized oracle system built on the Stacks blockchain using Clarity smart contracts. DORS provides reliable price feed data through a sophisticated stake-weighted consensus mechanism with multiple data source integration.

Overview

DORS solves the oracle problem in blockchain networks by implementing a redundant, stake-weighted system where multiple oracle nodes provide and verify data. The system ensures high reliability through economic incentives, round-based consensus mechanisms, and performance tracking.

Key Features

• Advanced Stake-Based Participation:

  • Minimum stake requirement: 1,000,000 microSTX
  • Stake-weighted voting power
  • Dynamic performance scoring

• Round-Based Consensus:

  • Time-windowed submission periods
  • Stake-weighted price aggregation
  • Outlier detection and filtering

• Performance Tracking:

  • Accuracy scoring system
  • Historical performance metrics
  • Weighted reputation scores

• Economic Incentives:

  • Rewards for accurate submissions
  • Penalties for deviation
  • Stake-based influence

Technical Architecture

Smart Contracts

The system consists of three main data structures:

;; Oracle Node Data
(define-map oracle-nodes 
    principal 
    {
        stake: uint,
        active: bool,
        accuracy-score: uint,
        total-submissions: uint,
        total-correct: uint,
        weighted-score: uint,
        last-submission-height: uint
    }
)

;; Price Round Data
(define-map price-rounds
    uint
    {
        final-price: (optional uint),
        submissions-count: uint,
        consensus-reached: bool,
        round-closed: bool,
        total-stake-weight: uint
    }
)

;; Round Submissions
(define-map round-submissions
    {round-id: uint, oracle: principal}
    {
        price: uint,
        stake-weight: uint,
        verified: bool,
        rewarded: bool
    }
)

Key Functions

1. Oracle Registration and Management

   • register-oracle: Register as an oracle node with required stake
   • calculate-stake-weight: Compute node's influence based on stake and performance

2. Price Submission System

   • submit-price-with-weight: Submit price data with stake-weighted influence
   • finalize-round: Process submissions and determine consensus price

3. Consensus Mechanism

   • Round-based submission windows
   • Stake-weighted median calculation
   • Automatic round progression

4. Performance Tracking

   • Accuracy score calculation
   • Historical performance metrics
   • Dynamic stake weight adjustments

Setup Instructions

Prerequisites

• Stacks blockchain environment (testnet or mainnet)
• Clarity CLI tools
• Minimum stake amount in STX
• Node.js and npm (for testing environment)

Installation

1. Clone the repository:

git clone https://github.com/your-username/dors.git
cd dors

2. Install dependencies:

npm install

3. Deploy the contract:

clarinet contract deploy oracle-system

Usage

To register as an oracle:

(contract-call? .oracle-system register-oracle)

To submit price data:

(contract-call? .oracle-system submit-price-with-weight u1000000)

To check round status:

(contract-call? .oracle-system get-round-status u1)

Testing

Run the test suite:

clarinet test

Security Considerations

• Minimum stake requirement prevents spam
• Time-windowed submissions prevent manipulation
• Stake-weighted consensus reduces attack vectors
• Performance tracking identifies malicious actors
• Economic penalties for bad behavior

Development Phases

Phase 1 (Completed)

• Basic oracle registration
• Simple price submission
• Administrative controls

Phase 2 (Current)

• Enhanced consensus mechanism
• Stake-weighted reporting
• Round-based submissions
• Performance tracking
• Economic incentives

Future Phases

1. Multiple data source integration
2. Advanced verification methods
3. Cross-chain compatibility
4. Governance mechanisms
5. Advanced economic models
