Results for “Interoperability vs Bridge”

Interoperability

Interoperability is the ability of separate blockchains to exchange information and assets. Blockchains are built in isolation with different rules, so they cannot talk to each other natively; bridges and similar systems are built to connect them.

What it means for you. Moving a token to another chain usually means a bridge issues a version of it on the other side, so what arrives can be a wrapped token whose value depends on that bridge. Bridge contracts have been hacked for very large sums, so check who runs a bridge and how it holds funds before using it.

Bridge

A bridge is a service that moves tokens or information from one blockchain to another. Usually it locks your tokens on the first chain and issues a matching wrapped token on the second, which can be redeemed back through the bridge.

What it means for you. The wrapped token you receive is only worth what the bridge can redeem, so a bridge hack or bug can leave it unbacked; very large sums have been stolen this way. Some bridges are run by a small group of operators who could block or take funds. Check that the destination chain and token address are correct before sending.
