Because the target blockchain smart contract cannot mint USDT itself, it must rely on pooled assets on either side of the bridge. For a user to send USDT from Ethereum to Solana, there must already be more USDT in the target chain’s smart contract than the total being sent. Blockchain bridges are important because they allow for interoperability between different blockchain networks.
There are architectural flaws in both trusted as well as trustless platforms that compromise the security of the blockchain bridge in various ways. Some crosschain protocols enable the same asset to move between different blockchains. Centralized stablecoins — like USDT or USDC, for example — are deployed on multiple networks.
In the end you will program the token balance function to process the bridging. After you have deployed both network bridges, start minting and burning the IToken. Please see our previous post for more on the benefits of porting tokens. Porting a token via a cross-chain allows greater exposure for a DApp or DeFi protocol. Blockchain Magazine, an independent platform, covers and publishes blockchain news, insights, analysis, research and review. Get familiar with the terms related to blockchain with Blockchain Basics Flashcards.
A blockchain bridge might seem like the most practical choice for extracting the actual value benefits of the blockchain ecosystem. However, bridges also present certain setbacks, which should be the priority of everyone in the blockchain landscape. Just like the web3 industry, blockchain bridges are still in the early stages of development. On top of it, the community of blockchain developers believes that the best design for a blockchain bridge has not been created yet.
Like any physical bridge, a blockchain bridge acts as the missing link between two blockchain ecosystems, making the transfer of information, data and tokens across them fairly easy. It’s a huge deal in the world of decentralized finance because it introduces connections between previously isolated networks. Seamless transfer of assets to and fro different blockchain networks can also help developers overcome conventional barriers in dApps development. As the popularity of blockchain applications such as DeFi apps, NFTs and DAOs continue to grow; bridges can offer seamless user experiences.
Today’s most widespread bridge implementations use a simple “mint and burn” approach to bridge assets. Assets are locked in a smart contract on the source chain before the target blockchain smart contract mints a wrapped version of that asset. For example, when using the Wormhole Ethereum/Solana https://www.xcritical.in/ Portal, you would deposit ETH on Ethereum and receive Wormhole Wrapped ETH on Solana. The internet is a revolutionary system partly because of its high interoperability. Blockchain bridges are critical to enhancing the blockchain industry’s interoperability and mass adoption.

One of the primary reasons for these hacks, as stated by CoinTelegraph, is open-source code and copy-pasting code. With open-source code, blackhat hackers can review a bridge’s code for vulnerabilities. If a bridge’s developer copy pastes code from another bridge, they may copy the same vulnerabilities. LogRocket is like a DVR for web and mobile apps, recording everything that happens in your web app or site. Federations allow trustworthy groups to validate occurrences on one chain on another. This is also a robust approach, but it relies on third parties or mediators, which can be a limitation in some cases.
- This is akin to a peer-to-peer network where each node acts as a “router” that holds an “inventory” of assets of both the source and destination chain.
- Therefore, blockchain bridges have become one of the inevitable necessities for the decentralized application ecosystem.
- Moreover, the decentralized nature of blockchain can make it difficult to enforce privacy laws and regulations, further complicating matters.
- The original asset is frozen, and you’ll get an equivalent token in exchange.
- As the cost to use the network has increased over the years in tandem with the demand for block space, the need for alternate networks became increasingly apparent.
Interoperability refers to the capacity of blockchains, which share the same underlying architecture, to communicate with one another in order to facilitate information sharing. It is the capacity to observe and access data stored in another blockchain. With interoperability, when information is delivered to another blockchain, a user on the other side may access it, and react effectively. Blockchain bridges help to minimize traffic on congested blockchains, such as the Ethereum ecosystem, and distribute it over other, less crowded blockchains, enhancing the Ethereum network’s scalability. In this guide, we’ll take a deep dive into how blockchains communicate, share data, and transfer assets.
A single chain’s throughput capacity bottleneck could hinder large-scale blockchain interoperability. There is usually a group of validators that monitor a “mailbox” address on the source chain and, upon consensus, perform an action on the destination chain. An asset transfer is typically done by locking up the asset in the mailbox and minting the equivalent amount of that asset on the destination chain. These are often bonded validators with a separate token as a security model. According to analysis from blockchain analytic firm Elliptic, the Wormhole attack occurred because Wormhole allowed the attacker to mint 120,000 worth of wrapped ethereum without having to stake any ETH.
The Avalanche team introduced an update for the bridge in June 2022 and included support for transferring assets between Bitcoin blockchain and Avalanche network. The definition of a blockchain bridge and the underlying rationale showcases a detailed impression of their importance. At the same time, you must what is a blockchain bridge and how it works have some doubts about the types of blockchain bridges and their work. Interestingly, an overview of the different variants of a blockchain bridge could shed further light on their work. Just like blockchain networks featuring distinctive defining parameters, blockchain bridges also have different traits.
It enables the protocol to punish node operators that approve fraudulent messages and even compensate users who might lose money. As we’ve established, blockchains cannot natively communicate with one another. Therefore, crosschain bridges need something between the source and target blockchains to pass the message across. If the user deposits 1,000 USDT on Ethereum, they will withdraw the 1,000 USDT a Solana user previously deposited — minus whatever fees the bridging protocol itself charges.
This allows Financial Transaction based on BlockChain technology or DTL which is executed with the help of BitCoin. This type of Version is permissionless as any participant will perform valid transaction of Bitcoin. It primarily focused on the development and creation of new cryptocurrencies. Due to that, it is vital for users to do their due diligence before interacting with any bridging ecosystem, which includes checking the documentation, the code and the maturity of the system. This is a means of protecting their crypto while the developers find a solution to overcome the limitations of current blockchain bridging protocols.
