A crypto bridge, otherwise known as a cross-chain bridge, connects two blockchains and allows users to send cryptocurrency from one chain to the other. Let's explore more in this article.
What is a Crypto Bridge?
With the help of a blockchain bridge, tokens or data can be transferred between two distinct blockchain ecosystems. The current lack of interoperability with blockchains is a significant issue.
Developers are often locked onto that platform once they create a decentralized application there and are unable to benefit from other blockchains' features.
For instance, many developers undoubtedly believed that Ethereum's well-documented scalability issues would have been resolved by this point. If they switch to a faster platform like EOS, they lose the advantages that Ethereum does have to offer, such as a large community, a widely accepted token standard, and the most widely utilized smart contract platform.
As a result, a developer can utilize a bridge to transfer their token between blockchain platforms, taking advantage of both. Tokens, data, and smart contracts might possibly move between many different platforms in a blockchain ecosystem that is genuinely interoperable.
Bridges typically employ a mint-and-burn protocol to maintain a steady token supply across all platforms. When a token leaves one blockchain, it is locked or burned, and a new token with the same value is created on the other blockchain. Conversely, when the token moves back to its original network, the “twin” token is burned or locked.
Types of Blockchain Bridges
The two notable categories of blockchain bridges include trust-based and trustless bridges.
Trust-based bridges also referred to as custodial or federation bridges, work like centralized platforms. These types of bridges would need a central entity for operations. Users have to depend on the members of the federation for verifying and confirming transactions. On top of it , the federation members receive hefty incentives for keeping their transactions operational rather than maintaining safety from fraud.
The second category of blockchain bridges, ie, trustless bridges, is actually decentralized bridges, which utilize machine algorithms for their operations. Trustless bridges work as a real blockchain network, wherein each associated network can contribute to validating transactions. Trustless bridges can also offer improved security alongside flexibility in cryptocurrency transfers.
Why Do We Use a Crypto Bridge?
Transferring assets from one blockchain to another has a wide range of advantages. First, the blockchain onto which you migrate assets may be less expensive and quicker than it. This is undoubtedly the case for Ethereum, where high transaction costs and sluggish throughput make it challenging for beginners to participate in decentralized banking (DeFi).
Investors could trade ERC-20 tokens for a fraction of the cost without giving up exposure to Ethereum tokens if they ported assets to a layer 2 network, a faster blockchain that sits atop the Ethereum blockchain, like Arbitrum or Polygon.
Bridges could be used by other investors to take full advantage of marketplaces that are restricted to a different blockchain. For instance, the DeFi protocol Orca, which supports a wrapped version of ETH, is only available on Solana.
The utilization of bridges is becoming easier. Many DeFi protocols contain built-in bridges that enable users to exchange tokens between protocols without leaving the site. As a result, converting tokens over bridges is made simpler.
