Peg Zones (Cosmos)

Peg zones are specialized blockchains within the Cosmos ecosystem designed to function as bridges between the Cosmos network and external, non-IBC blockchains like Bitcoin or Ethereum. These zones maintain a "peg" to external assets by holding reserves of those assets and issuing equivalent representations (pegged tokens) that can be traded on Cosmos chains with full IBC composability. A peg zone validates transactions on the external chain using a validator set and consensus rules specific to that blockchain, ensuring that pegged assets maintain one-to-one backing. This architecture enables Cosmos-based applications to access liquidity and assets from major blockchain ecosystems while preserving the interoperability benefits of IBC. Example: Gravity Bridge serves as a peg zone connecting Ethereum to Cosmos, allowing Ethereum-based tokens to be locked in a smart contract and represented as native Cosmos assets that can transfer via IBC to any connected zone with full security guarantees. Why it matters for cross-chain interoperability: Peg zones extend Cosmos's interchain vision to non-IBC networks, enabling capital efficiency and composability across the broader blockchain ecosystem by trustlessly bridging isolated chains through specialized consensus mechanisms and asset verification.
