# Galactica Network Overview

## What is Galactica Network?

Galactica Network is a **Layer 2 blockchain built with the Arbitrum Orbit SDK**, designed to provide the core infrastructure for **compliant, privacy-preserving identity and reputation** in decentralized finance (DeFi), decentralized society (DeSoc), and real-world asset (RWA) applications.

Galactica leverages Arbitrum’s secure, scalable L2 architecture while introducing its own identity-centric execution environment - the **Identity Virtual Machine (IVM)** - purpose-built to power zkKYC, and programmable compliance across chains.

Core components of Galactica include:

* **ZK Certificates**\
  On-chain, non-transferable attestations (e.g. zkKYC) that verify zero-knowledge proofs of off-chain data, such as age, jurisdiction, or accreditation, without revealing the underlying information. These credentials are issued and validated through trusted Guardians.
* **Reputation Engine (Soul Scores)**\
  Galactica computes on-chain and off-chain signals into customizable reputation metrics, enabling trustless credit scoring, governance weighting, and airdrop eligibility all while preserving user privacy.
* **Contingent Transactions**\
  Smart contract actions can include dynamic identity and compliance checks, such as verifying if a user is over 18, in a permitted region, or above a minimum reputation threshold before allowing execution.

## 🔗 Key Integrations and What They Unlock

* **Alchemy**\
  Galactica runs on Alchemy’s high-throughput Supernode infrastructure, enabling sub-second zkKYC attestations, gasless transactions (via ERC-4337).
* **Hyperlane**\
  Galactica integrates with Hyperlane for permissionless cross-chain messaging, allowing zkKYC credentials to move securely between EVM and non-EVM chains.
* **The Graph**\
  Galactica identity data (SBT, zkProof, etc.) is indexed through The Graph’s decentralized infra, unlocking real-time compliance logic and credit flows across DeFi and RWA protocols.
* **Arbitrum Orbit**\
  As a chain built with Orbit, Galactica benefits from 100% on-chain validation, rapid finality, and seamless bridging for identity-linked assets and credentials.

## 🚀 Use Cases

 Galactica’s stack powers a wide range of applications:

* **Regulation-Ready DeFi**\
  Enable compliant access control and structured products using zkKYC, encrypted identity proofs, and on-chain attestations, integrated with partners like Syntetika and Hilbert Group.
* **Omnichain Identity & Airdrops**\
  Through Hyperlane and Orbit, Galactica makes it possible to **verify once, use everywhere**, distributing identity-bound tokens, gated airdrops, and cross-chain credentials with zero data leakage.

***

## 🧠 Final Word

Galactica is not just a chain - it’s the **identity and reputation layer for the multichain world**. Built on Arbitrum Orbit, scaled by Alchemy, indexed by The Graph, and connected by Hyperlane, Galactica brings together privacy, compliance, and composability to unlock the next era of decentralized applications.<br>
