A bridge is a blockchain protocol that is used to create an outline between minting and burning procedures to ensure a constant supply of tokens for the different platforms. Bridges can also be used as a transition among several Blockchain protocols.

Once you lock a token in a given Blockchain protocol, its equivalent counterpart is minted in the other Blockchain ensuring interoperability between them. This transfer is possible under the mint-and-burn protocol.

Developers can make the best use of Blockchain bridges with their faster processing speed backed by lesser overloaded Blockchain.
