8. IBC Integration

8.1 Inter-Blockchain Communication Overview

IBC enables Nonterritorial to communicate with other Cosmos chains without bridges or intermediaries:

┌─────────────────┐         IBC          ┌─────────────────┐

└─────────────────┘                      └─────────────────┘

8.2 IBC Use Cases

Token Transfers

• UNT can move to other chains for liquidity (controlled)

• Stablecoins can enter for fiat-denominated licensing

• Cross-chain payment settlement

Data Sharing

• Provenance data shared with archive chains

• Artist credentials verified across chains

• Exhibition metadata interoperability

Governance Coordination

• Cross-chain proposals affecting multiple networks

• Shared constitutional protections

• Ecosystem-wide parameter coordination

8.3 Supported IBC Connections

Phase 1 (Launch)

Chain	Purpose
Cosmos Hub	Ecosystem anchor, shared security option
Osmosis	Liquidity for UNT (controlled, non-speculative)

Phase 2 (Year 2)

Chain	Purpose
Stargaze	NFT interoperability (provenance only)
Juno	Smart contract interoperability

Phase 3 (Year 3+)

Chain	Purpose
Cultural Partners	Other sovereign cultural chains
Archive Chain	Long-term preservation network

8.4 IBC Security Considerations

• Light client verification ensures trustless communication

• Relayer incentives aligned with network operation

• Timeout parameters prevent stuck transactions

• Packet filtering for unwanted message types
