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. In other words, blockchain bridges are a critical component of an interoperable future of the blockchain industry. A specific blockchain bridge could not support and work with every blockchain network or asset in the decentralized applications industry. In addition, you can find a list of blockchain bridges focused on addressing unique user requirements.
- The bridges provide seamless transactions between popular blockchain networks.
- Bridges exist to connect blockchains, allowing the transfer of information and tokens between them.
- These work with smart contracts controlling the crypto locking and minting procedures.
- To use the Binance Bridge, for example, you will first select the chain you’d like to bridge from and specify the amount.
- They are called altcoins because they are considered alternative currencies to Bitcoin.
- This could either be in the form of censorship of access or transaction, bad faith on the part of the central point of control (rug pull) or the vulnerability to external attack.
Impermanent loss is a risk that occurs when participating in DeFi liquidity pools. It happens when the price of your deposited assets change from the time you deposited them. In both cases one side of the bridge was exposed through a technical vulnerability. This doesn’t just lead to the loss of assets held by the exposed end of the bridge but has https://www.xcritical.com/blog/what-is-a-blockchain-bridge-and-how-it-works/ significant knock-on effects. In February the Wormhole Bridge hack saw 120,000 Wrapped Ether (wETH) tokens, valued at $326million, stolen from the Solana side of a bridge to Ethereum. A centralised service verifying data is a single point of failure because it can censor a transaction or simply abuse the trust that you have to place in them.
Blockchain Bridges: What are They and Why We Need Them?
To evaluate trustless bridges based on other factors, we must break them down into generalized message passing bridges and liquidity networks. Blockchains have unique strengths, weaknesses, and approaches to building applications (such as speed, throughput, costliness, etc.). Bridges help the development of the overall crypto ecosystem by enabling blockchains to leverage the innovations of each other.
As compared to a trusted blockchain bridge, the trustless variant leverages algorithms and smart contracts over a blockchain network. Therefore, a trustless blockchain bridge does not need any central intermediaries or custodians. The conventional consensus mechanism or Proof of Work serves better security, although with additional expenses on energy consumption. Therefore, new blockchain networks have been evolving with the help of innovative consensus models, such as Proof of Stake.
Why do we need blockchain bridges?
Trustless bridges according to multiple opinions are probably the key solution to developing seamless interoperability for all existing blockchains out there. Users, that are aware of different chains see the different dAPPS that they would like to use, or NFTs that they want to acquire with a different token or coin, that exists on a different blockchain. Even if we are creators of a crypto project, we are in any way the users of a blockchain. To deploy a dapp on multiple chains, developers can use development platforms like Alchemy(opens in a new tab)↗, Hardhat(opens in a new tab)↗, Truffle(opens in a new tab)↗, Moralis(opens in a new tab)↗, etc. Typically, these platforms come with composable plugins that can enable dapps to go cross-chain. For instance, developers can use a deterministic deployment proxy offered by the hardhat-deploy plugin(opens in a new tab)↗.
The most important benefit of blockchain bridges is the ability to improve interoperability. They enable the exchange of tokens, assets, and data across different blockchains, whether between layer 1 and layer 2 protocols or various sidechains. For example, WBTC enables bitcoin users to explore the decentralized applications (dapps) and DeFi services of the Ethereum ecosystem. An interoperable blockchain sector is critical to the industry’s future success.

Blockchain bridges are critical to enhancing the blockchain industry’s interoperability and mass adoption. They have enabled some essential innovations, allowing users to exchange assets between many blockchain protocols. Blockchain bridges have grown significantly in the number of bridges, users, and total transaction volume.
You can find a few blockchain bridge projects making their way towards popularity. The bridges provide seamless transactions https://www.xcritical.com/ between popular blockchain networks. In addition, every bridge has a different approach to operations based on its time.
What is a Blockchain Bridge For?
For example, users cannot simply move their Bitcoin to the Ethereum blockchain. BNB Chain, also known as Binance Smart Chain, was the victim of an attack in October 2022 that resulted in losses estimated at $570 million. Blockchain bridge analysis vendor Chainalyis has estimated that 69% of cryptocurrency funds stolen in 2022 have been attributed to attacks on cross-chain bridges. Bridge services “wrap” cryptocurrency to convert one type of coin into another.
If you have ETH on Ethereum Mainnet and you want to explore an alt L1 to try out their native dapps. You can use a bridge to transfer your ETH from Ethereum Mainnet to the alt L1. Central to this discussion has been the term “Shibarium”, linked directly to Shiba Inu, it’s not some esoteric concept but a pivotal layer-2 blockchain rooted in the Ethereum foundation. This network, besides its value proposition for gaming and metaverse applications, offers an affordable settlement option for DeFi applications. Shiba inu has been grabbing headlines for more than two years now, and their latest venture? The mainnet went live just yesterday, marking a significant milestone for Shiba Inu and its community.
