Foundations: Interoperability / Bridge
What Is a Light Client Bridge?
A light client bridge tries to answer the hardest question in interoperability without trusting a custodian: how can one chain know what really happened on another? It does this by running a compact verifier of the source chain on the destination chain, so cross-chain actions are accepted only when they can be proved against source-chain consensus.

What is a Bridged Asset?
A bridged asset is a token on one blockchain that stands in for an asset that really originates on another. That sounds simple, but the important question is not what the token is called — it is what guarantees that the token is actually backed, redeemable, and still valid if something goes wrong.

What is a Canonical Bridge?
A canonical bridge is the asset pathway a chain treats as official. That sounds like a branding detail, but it changes the trust model: users are not just relying on a bridge operator, they are relying on the chain’s own protocol, contracts, and withdrawal rules.

What is Bridge Relay?
A bridge relay is the off-chain agent that makes cross-chain communication actually move. Chains may be able to verify foreign state, but without someone watching one chain, packaging the right proof or attestation, and submitting it to another, the bridge does not live.

What is Bridge Risk?
Bridge risk is the price of making separate blockchains behave like one system. Whenever a bridge moves assets or messages across chains, it must answer a hard question: who is trusted to decide that something really happened on the source chain, and what happens if that answer is wrong?

What is a Bridge?
A blockchain bridge exists because blockchains do not naturally share state. To move assets or instructions across chains, a bridge has to answer one hard question: how can chain B trust that something really happened on chain A?
