INTEROPERABILITY AND CROSS-CHAIN FINANCE

Cross-Chain Bridge

A protocol that facilitates the transfer of tokens or data between two separate blockchain networks, enabling assets issued on one chain to be used on another.

EXAMPLE

A regulated cross-chain bridge with embedded KYC checks allows a tokenized bond issued on a permissioned bank chain to be posted as collateral on a public DeFi lending protocol.

Related Terms

Interoperability

The ability of different blockchain networks, protocols, and traditional financial systems to exchange data and value seamlessly. Institutional adoption depends on cross-chain interoperability solutions that connect permissioned and public blockchains.

Example

Chainlink's Cross-Chain Interoperability Protocol enables banks to move tokenized deposits between different blockchain networks while maintaining a single source of truth for regulatory reporting.

Permissioned Blockchain

A blockchain network where participation—reading, writing, or validating—is restricted to pre-approved entities. Permissioned chains offer privacy and regulatory control suited to institutional and consortium use cases.

Example

JPM Coin operates on a permissioned blockchain, ensuring only verified institutional counterparties can initiate or receive transfers.

Real-World Asset

A traditional financial or physical asset—such as a government bond, real estate, private credit facility, or trade receivable—that has been tokenized and represented on a blockchain for on-chain trading, settlement, or collateral use.

Example

BlackRock's BUIDL fund tokenizes U.S. Treasury exposure, allowing institutions to use the token as real-time on-chain collateral instead of wiring cash.
