The development of the blockchain industry is driven by constant innovations. There are the pioneer protocols like the Bitcoin and Ethereum networks, followed by a myriad of alternative layer 1 and layer 2 blockchains. To monitor contract activity across chains, developers can use subgraphs and developer platforms like Tenderly to observe smart contracts in real-time. Such platforms also have tools that offer greater data monitoring functionality for cross-chain activities, such as checking for events emitted by contracts(opens in a new tab), etc.
You have the Indian currency – the rupee, but you need pounds in England for daily transactions. Interoperability between blockchains is one of the biggest challenges to fully optimizing the utilities of the groundbreaking tech that blockchain is. Each blockchain is constrained by the boundaries of its area, despite being flexible and relatively effective as a standalone entity. Although every blockchain has some cons, for instance, Ethereum has scalability issues for which it needs ZK-rollups and layer1 scaling solutions. Avalanche and Solana L1s are designed with distinct architectures that prioritize increased throughput but sacrifice decentralization.

Web3 has now evolved into a distributed ecosystem due to the introduction of side chains. But both of these original chains (L1) and (L2) scaling solutions come with their unique features and trade-offs. As more blockchain technologies are developed, there is an increasing demand for asset transfers. Actors monitor events on the source chain and generate cryptographic inclusion proofs about past events that were recorded on that chain. There is a requirement for some actor to “relay” the block headers and proofs.
Will Central Bank Digital Currencies (CBDCs) Replace Fiat Currencies?
They are trustless, meaning that the bridge’s security and that of the underlying blockchain are identical. This can enhance the liquidity and accessibility of tokenized assets, opening up new opportunities for investment and trade. Tokenization involves representing real-world assets on the blockchain, providing increased liquidity, accessibility, and efficiency.
For example, a user who locks in their ether (ETH) on one blockchain will receive a “wrapped” ether (wETH) on another blockchain. This allows Billy to use a bridge to send wrapped bitcoin (wBTC), which works on the Ethereum blockchain, to Ethel in a more seamless fashion. Avalanche Bridge is a cross-chain bridge that transfers assets between different blockchain networks. It is designed to improve the scalability and interoperability of the Avalanche ecosystem and supports a broad range of assets.
One example is xDai Bridge, which connects the Ethereum mainnet to Gnosis Chain (formerly xDai blockchain), an Ethereum-based stable payment sidechain. XDai is secured by a set of validators different from those who maintain the Ethereum network. In blockchain bridge, another crypto’s tokenized version is often referred to as a wrapped token. It is originally linked to the digital assets it points to and can be unwrapped whenever you want. Blockchain bridge has a primary function to make interoperability possible. Interoperability defines how well digital and data assets stored on a blockchain network can communicate.
Shortly after the inception, different blockchain protocols with unique consensus algorithms surfaced which also increased the adoption of crypto. Now that most of the blockchain protocols are autonomous ecosystems with independent economies, cross-chain communication becomes an unavoidable need. blockchain bridge Though blockchain technology is un-hackable, there are still other risks that significantly disrupt user operations. Software breakdown, buggy source code, human errors, and cyber-attacks are some of the major risks that can potentially affect user experience across the web3 ecosystem.
Blockchain Bridges: Introduction and Functioning
Custodial bridges require users to place their trust in a central entity to properly and safely operate the system. Users should do extensive research to ensure that this entity is trustworthy. Blockchain bridges can be categorized according to their functions, mechanisms, and levels of centralization. Web3 games and other projects can now port their token across multiple chains and reduce network stress.

However, this would incur transaction fees and expose you to price volatility. To understand what a blockchain bridge is, you need to first understand what a blockchain is. Bitcoin, Ethereum, and BNB Smart Chain are some of the major blockchain ecosystems, all relying on different consensus protocols, programming languages, and system rules. Put simply, bridges unlock numerous use cases by allowing blockchain networks to exchange data and move assets between them. Bridges offer a way for isolated blockchain environments to connect with each other.
While most external validators today are trusted models, some are collateralized, of which a subset is used to insure end-users. Furthermore, if the collateral asset is different from the insured asset, there is also a dependency on an oracle price feed, so the security of the bridge could degrade to the security of the oracle. If not trusted, these bridges are also the least capital efficient because they need to scale collateral proportional with the economic throughput they are facilitating. 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. These networks usually leverage the security of the underlying blockchain; through the use of locking and dispute mechanisms, users are guaranteed that routers cannot run away with user funds.
Popular Blockchain Bridge Examples
This is certainly true for Ethereum, where high transaction fees and slow throughput make it difficult for newcomers to get involved in decentralized finance (DeFi). The frequency of these bridge hacks has become a warning signal for users and a significant threat to building trust in blockchain https://www.xcritical.in/ technology. As adoption of cryptocurrency accelerates, the industry is facing growing pressure to fix the flaws that have allowed these exploits. With the inception blockchain in 2008 via Bitcoin’s whitepaper release, people got to know about the innovation of a decentralised ecosystem.
In most cases, blockchain bridges leverage different mechanisms to overcome trust issues between chains. The off-chain actors enable trust and communications between different chains. 2021 was the year of the L1s – which resulted in many predicting a multi-chain future for crypto, as opposed to a winner take all stance that many had prior to the rise of these blockchains. However, with the drastic increase in the number and size of different blockchain ecosystems, there is now a need for key infrastructure to connect them.
Unidirectional blockchain bridges don’t allow users to transfer assets to their native blockchain. Such type of Blockchain Bridges ensures irreversible asset transfers across blockchain networks. For example, trusted blockchain bridge presents the concerns of censorship due to centralized control. On top of it, the custodial risks of exposing assets to malicious bridge operators could also affect users. At the same time, a trustless bridge would also present risks in the form of malware or bug risks in the smart contract code.
- Sidechain bridges help regulate assets between two independent blockchain networks without involving any intermediaries.
- Let’s say you want to exchange ETH on Ethereum Mainnet for ETH on Arbitrum(opens in a new tab).
- Now let’s move ahead and comprehend the mechanism of a blockchain bridge with the help of an example like bridging between BSC to ETH in the following section.
Connecting blockchains could potentially allow malicious actors to exploit the bridge and access assets or information stored on either chain. Cross-chain bridges connect two or more blockchain ecosystems, including main chains and side chains. An example is Ethereum as an L1 main chain, with Arbitrum as its official L2 side chain. The top four benefits of blockchain bridges include communication between blockchains, flexibility, efficiency, and scalability. Light clients & relays are also strong with statefulness because header relay systems could pass around any kind of data.
