What Are Bridges In Blockchain And How Do Cross
The centralized entity behind a custodial bridge could theoretically steal users’ funds. When using custodial bridges, go for established brands with long-term track records. It’s pegged to the value of the asset it represents and typically can be redeemed for it at any point.
However, this would incur transaction fees and expose you to price volatility.
A blockchain bridge is a protocol connecting two blockchains to enable interactions between them. If you own bitcoin but want to participate in DeFi activity on the Ethereum network, a blockchain bridge allows you to do that without selling your bitcoin. Blockchain bridges are fundamental to achieving interoperability within the blockchain space. A blockchain bridge also known as cross-chain bridge is a connection between blockchains that allows users to transfer tokens, assets and/or arbitrary data from one chain to another.

How Bridges Work?
Bridges provide flexibility – It enables user to transfer assets and valuable data from one blockchain to another. This enables users to access the benefits of different blockchain technologies and they aren’t limited to the capabilities of one particular chain. Coin Guides is a fast-growing cryptocurrency publication that helps users to understand the Blockchain Technology and Crypto Currency. We publish latest crypto news, coin mining guides, wallet setups, reviews, token guides, trading tips, online security and various other aspects of cryptocurrencies. Now bridges cover the gaps between different ecosystems so that growth is not limited to one single chain.
- Cross-chain bridges are becoming an important piece of DeFi ecosystem due to the growing list of blockchains.
- Likewise using bridges in blockchain users can easily transfer tokens and other crypto assets between two or more networks.
- They are needed because the parent and sidechain may have different consensus mechanisms.
- Additionally, Ethereum also levies high fees on transactions during heavy network traffic.
- Since it enables connection between the main chain and secondary chain it can distribute the transaction loads across their ecosystem.
- They allow users to access new protocols on other chains and enable developers from different blockchain communities to collaborate.
Additionally, Ethereum also levies high fees on transactions during heavy network traffic. By using a blockchain bridge, a dApp can be executed on Ethereum for smart contract functionality; and transactions can be executed on another blockchain for processing at a higher speed and a lower cost. A Trustless blockchain bridge works more or less like a public blockchain network, where anybody can join the platform without any permission. Just as the miners on Ethereum are incentivized with gas for validating transactions, users on the Trustless blockchain bridge are incentivized for affirming transactions. The Syscoin-Ethereum blockchain bridge is a famous example of the trustless bridge which enables trustless interoperability between Ethereum and Syscoin’s network. The development of the blockchain industry is driven by constant innovations.
So that they can use dapps interchangeably and leverage other DeFi services more efficiently. These bridges are also called as wrapped bridges that issues pegged tokens matched one to one on either blockchain. One of the most popular trust based bridge scenario is the initiative that enables hodlersof Bitcoin to transfer their BTC as Wrapped Bitcoin to Ethereum blockchain.
Benefits Of Blockchain Bridges
Some blockchain bridges can handle a large number of transactions, improving efficiency. For example, the Ethereum-Polygon Bridge is a decentralized two-way bridge that works as a scaling solution to the Ethereum network. As a result, users can benefit from faster transactions and lower transaction costs.
Cross-chain bridges are becoming an important piece of DeFi ecosystem due to the growing list of blockchains. All that growing list means the value continues to spread among blockchains. As far as the need for enhancing interoperability between blockchains is concerned, cross-chain technology is one of the most effective solutions to facilitate the same. While Blockchain has brought the much needed decentralization and disruption in possibly every field that exists today, there do exist some challenges with Blockchain that require introspection. One of them is the insufficiency of two blockchains operating together.
There are many decentralized cross-chain bridges – A new type of protocol that made possible for users to transfer assets between blockchain without the need of centralized third party service. Now users can move their assets across different blockchains in an automatic and in a permission-less way. Now that we’ve understood the benefits of bridges in blockchain lets see how cross chain swaps work. Another example of a blockchain bridge is the RSK token bridge that enables interoperability between Bitcoin and Ethereum for the transfer of assets. Assets on blockchain A will unlock only when the equivalent amount of minted tokens on blockchain B gets burned or locked again. This prevents users from using the assets on both blockchains at the same time.
Non-custodial bridges operate in a decentralized manner, relying on smart contracts to manage the crypto locking and minting processes, removing the need to trust a bridge operator. In this case, the system’s security is as good as the underlying code. Centralized cross chain bridge uses centralized system and they are based on a third party trust.
Bitcoin, Ethereum, and BNB Smart Chain are some of the major blockchain ecosystems, all relying on different consensus protocols, programming languages, and system rules. When you initiate a transfer of assets from one blockchain to another using a bridge the assets are in fact not relocated or sent anywhere. Instead the transfer functionality is leveraged through a two step process and is all handled by the smart contract. Most bridges in order to transfer asset between chains they lock up the assets on source chain and mint equivalent amount of wrapped assets on the destination chain. They can even conduct micro-transactions on chain quickly and without having to worry about high transaction costs. Ability to conduct fast, low cost transaction simply enhances the DeFi and DApp experience.
Finally, blockchain bridges could expose the underlying protocols to risks related to the disparity in trust. Because blockchain bridges connect different blockchains, the overall security of the interconnected networks is as strong as the What is a Blockchain Bridge weakest link. Aside from enabling cross-chain transfers, blockchain bridges provide other benefits. They allow users to access new protocols on other chains and enable developers from different blockchain communities to collaborate.
Unlike CEX in a decentralized system users don’t have to sign up and there is no collection of user data either. Instead of putting trust in a centralized authority; users place their trust in the mathematical truth. In blockchain system the mathematical truth is achieved when the computer nodes or when a program reaches a common agreement in accordance to the rule specified in the underlying blockchain’s codebase.
These centralized services that facilitate cross chain activity have some cons such as charge of high fee for transfers, need of KYC registration etc. But these days users no longer rely on these centralized services to perform token swaps. It basically locks up the BTC on Bitcoin and mints equivalent BTC tokens on Ethereum. When you want to transfer the BTC back to Bitcoin network the wrapped tokens on Ethereum will be locked or burned and locked BTC on Bitcoin will get unlocked for you. For example even Today from your Binance account you can swap and transfer your Ethereum ERC20 to Solana chain, to BEP20 , ARC20 Avalanche chain, Polygon networkand many other supported chains. Not only Binance but many exchanges do offer the possibility to swap tokens between blockchains.
Why Do We Need Blockchain Bridges?
There are the pioneer protocols like the Bitcoin and Ethereum networks, followed by a myriad of alternative layer 1 and layer 2 blockchains. Attackers have exploited the vulnerabilities of some blockchain bridges’ smart contracts. Massive amounts of crypto have been misappropriated by malicious actors from cross-chain bridges.
The development of Blockchain bridges is still at a premature stage and may take considerable time to grow into a full fledged bankable application. But given its useful, unique aspect of bridging multiple Blockchain ecosystems, it goes without saying that it will play a major role in the Blockchain universe in the future. On the lines of Public and Private blockchains, blockchain bridges are also divided into two categories namely Trustless blockchain bridge and Federated blockchain bridge. 1) A blockchain bridge is an interconnected link that enables communication and interaction between two blockchain systems.
As Web 3 continues to expand bridges become more crucial as they open doors across the ecosystem. Cross-chain interoperability is the way to create maximum value for users. Also in order to ensure scalability and connectivity among the DeFi ecosystem the need to connect blockchains becomes critical. While these are building a parallel DeFi ecosystem to Ethereum there is also an increase in the number of new blockchains being launched. They are side-chains, layer two protocols, sharding or parachains or EVM compatible blockchain that are mainly designed to provide scaling solutions.
Bridging The Gap Using Blockchain Bridges
With this approach users are allowed to move any digital assets from one network to another without any third party assistance. This cross chain functionality connects blockchains and layer one protocols to bridge assets so that token holders can interact with DApps across the ecosystem. Blockchain bridges help break up these silos and bring the isolated crypto ecosystems together. An interconnected network of blockchains can allow tokens and data to be exchanged between them smoothly.
In other words, blockchain bridges are a critical component of an interoperable future of the blockchain industry. A cross-chain swap is a completely decentralized mechanism of exchanging tokens from one chain for non-native ones on the other chain. It is performed through special smart contracts – An application or a program that connects two different networks and perform the exchange of tokens automatically when specific conditions are met. There are so many DeFi ecosystems currently such as Ethereum, Polkadot, Avalanche, Cosmos, Fantom, Polygon, Terra , Harmony, Near, Optimism and many others. Each of these platforms have different protocols, have different rules and governance models. Due to their distinct features many DeFi users simply want to move their digital assets from one chain to another.
Allowing traffic between many blockchains and layers is beneficial during high transaction volumes especially when the main chain gets congested. Cross-chain collateral – Using cross chain bridge users can simply reap the rewards of all chains. One of the most popular scenario is Bitcoin users benefiting from the functionalities of DeFi on the Ethereum blockchain.
You will then deposit the crypto to an address generated by Binance Bridge. After the crypto is sent to the address during the time window, Binance Bridge will send you an equivalent amount of wrapped tokens on the other blockchain. If you want to convert your funds back, you simply go through the reverse process. To understand what a blockchain bridge is, you need to first understand what a blockchain is.
