🚀 Overview

SpaceDAO is a groundbreaking, community-driven initiative that revolutionizes space applications through decentralized collaboration and consensus. Our mission is to mitigate risks associated with centralized control of critical decision-making information in the space industry. The Space Traffic Management (STM) dApp, powered by these smart contracts, enables:

• Cross-validation of Conjunction Data Messages (CDMs) by Space Situational Awareness (SSA) data providers
• Optimized spacecraft maneuvering based on consensus data
• Global orbital situation oversight for regulators and space lawyers

💼 Smart Contracts

1. SpaceDAOID.sol:

• Manages user permissions and identity
• Stores comprehensive user information
• Implements role-based access control

2. Confidence.sol:

• Handles confidence scoring for data providers
• Implements adaptive confidence adjustment algorithms
• Supports multiple confidence categories (LEO, MEO, HEO, GEO)

3. ConsensusCDM.sol:

• Manages the consensus process for CDMs
• Implements weighted voting based on provider confidence
• Handles data submission, validation, and fusion

🏗 Architecture

Our decentralized application follows a robust architecture:

   A[Frontend Vue.js App] -->|Interacts with| B[Web3 Provider]
    B -->|Sends transactions to| C[Arbitrum Network]
    C -->|Executes| D[SpaceDAOID Contract]
    C -->|Executes| E[Confidence Contract]
    C -->|Executes| F[ConsensusCDM Contract]
    D <-->|Interacts with| E
    E <-->|Interacts with| F
    F -->|Emits events| G[Event Listeners]
    G -->|Updates| A
