Bridges building in blockchain

How to build a decentralized bridge between two blockchains?

What is a bridge?

A bridge is a mechanism that allows two blockchains with different governance processes to transact with each other. Bridges are needed for blockchain interoperability, which will allow the exchange of assets among different chains. Let’s say that you want to issue an asset on the Bitcoin blockchain and then transfer it to the Ethereum blockchain. In this case, you will need some kind of a bridge, because there are fundamental differences between these two chains.

Bridges are used to connect two separate networks together, allowing trustless and permissionless communication between the two. This is done by relaying transactions from one network to the other via a bridge node, which then performs some additional actions before broadcasting the transaction to the second network.

Bridges enable dApps on one blockchain to interact with smart contracts on another blockchain while remaining trustless and permissionless. They also help with token liquidity, allowing users to quickly trade assets between different blockchains without having to rely on their exchange of choice.
