Cross-chain bridges: their compatibility with Blockchains

In recent years, the number of different layer 1 and layer 2 blockchains has increased exponentially. Each of these networks is unique, works according to its algorithms and differs from others in terms of its characteristics. That is why smart contracts and tokens from one blockchain cannot be directly transferred to another. Bridge Smart Contract Development Services came to be the solution to this compatibility problem. And we are going to tell you about it in this article.

Cross-chain bridges and their advantages

Chain bridges are decentralized services that allow you to transfer assets and data between different blockchains or layer 2 scaling solutions.

Here are some of the reasons why they are useful to users:

flexibility — users are not limited by the capabilities of a single blockchain, but can take advantage of others;

adaptability — bridges connect the main and sub-chains, spread a transaction load across the network and thus improve its scalability;

Efficiency — They allow users to transfer assets to the higher-performing blockchain and conduct faster transactions with cheap gas fees.

The presence of cross-chain bridges opens up new perspectives for decentralized finance (DeFi) and decentralized applications (DApps), allowing them to combine the use of different blockchains and get the best out of each.

Why is chain bridging an inevitable trend?

The Silk Road has been an important trade route for mankind throughout history. Thanks to the Silk Road, Cross chain bridge development new lands and cultures were discovered and were the engine of the development of Asia and Europe in many fields.

Especially today, when blockchains have developed to a certain point, and each blockchain owns a certain number of assets and users, not the dominance of Bitcoin and Ethereum as before.

As a user, having a cross-chain bridge will help us:

Join the search for opportunities more easily .many steps from transferring assets from BSC to Binance and then to FTX and depositing them in Solana, but it can be through a transaction through the bridge.

Develop cross-chain applications . For example, an Aggregator project helps users deposit tokens on one chain but farm on another ⇒ From there, optimize profits.

And much more potential is waiting to be discovered.

How does the cross chain bridge work?

Currently, the number of projects working on cross-chain bridges is increasing day by day, which shows the real demand of users for fast cross-chain asset transfer.

Although the number of Build a cross chain bridge is quite a lot, in general, the projects are applying a model that is lock-mint-burn.

How the bridge between blockchain works

Chain bridges often use the freeze and mint mechanism due to the impossibility of directly transferring an asset from one network to another.

For example, a user wants to transfer his Ethereum token to the Solana blockchain. To do so, he sends the token to a special address on the Ethereum network, where it is frozen. At that very moment, a copy of the token is created on the Solana network. Its value will be linked to the value of the original token. The process looks a lot like a transfer, even though the original token never actually left their network.

To “return” to the original blockchain, the copy of the token in Solana is burned and the asset is unfrozen in Ethereum.

How to transfer assets using the funds stored in a smart contract

Another way to transfer assets is through a cross-chain bridge with funds stored in smart contracts. Suppose a user wants to transfer ETH to the BSC network. To do so, it sends ETH to one bridge pool and receives bscETH — the equivalent of ETH on the BSC network — from another.

For example, on the THORChain platform, ETH will be replaced with a RUNE token of equivalent value in the first pool, and the second pool will replace RUNE with bscETH. The reverse exchange is carried out according to the same principle.

Perspectives for cross-chain bridges

There is no reason to believe that one blockchain will ever dominate or replace others, as blockchain technology is constantly evolving and we see new projects popping up every day. With many networks competing with each other, there is a growing need for Build a token bridge that can connect different blockchains. Therefore, this trend is still in force and still has a lot to give.

conclusion

In short, cross-chain bridges are useful tools for transferring assets and data between different blockchains and layer 2 scaling solutions. They have the ability to solve the compatibility problem, opening up new perspectives for users.
