That means the app is stuck using the features of that single blockchain. Put simply, that locks the project out of benefits of other blockchains. Put simply, each blockchain has its own language, and they aren’t all cross-compatible. Another key difference is that atomic swaps are most commonly conducted between two transacting parties, while bridges are for users sending assets to themselves on another blockchain. Every cross-chain bridge is created differently, with some being more vulnerable than others when it comes to security.

Therefore, bridge developers should audit the important parts of their software. It supports about 88 blockchains, including Optimism, Ethereum, and Arbitrum. Then they can keep the ETH in their Binance wallet or send it to another Ethereum-compatible wallet. 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.

How to Transfer USDC Cross-chain from Ethereum to Arbitrum

It is implemented using smart contracts, which facilitate the swap of assets in a decentralized and trustless manner. Blockchain bridges can enable interoperability between different blockchains, which allows users to access and explore the features and capabilities of another network. A blockchain bridge (or cross-chain bridge) is a mechanism that allows for the exchange of data and cryptocurrencies between two separate blockchains. Rather than having many siloed ecosystems, bridges allow for communication and interoperability between many different chains. Bridges are critical infrastructure for the future of decentralized finance, as they support the flow of liquidity in and out of ecosystems. Blockchain bridges are important because they allow for interoperability between different blockchain networks.

• From that point, you can convert the wrapped BTC, and an equivalent number of BTC will be transferred to my wallet on the new network.
• A blockchain bridge is a technology that connects two blockchains to allow them to interact.
• You can perform the same thing using a blockchain bridge without losing the asset and gaining trading access to all of the assets available on the BNB Chain.
• Centralised bridges provide a solution to interoperability by compromising on the trustless component of the trilemma through External Verification; aka off-chain.
• Trustless bridges operate without an intermediary or trusted third party.
• The advantages of a blockchain bridge can offer benefits to developers and investors alongside the blockchain networks connected by the bridge.

While bridges have a great amount of utility, it’s important to consider the potential risks that can arise from sending crypto assets between blockchains. They exist as isolated domains with unique operating logic, prioritising https://www.xcritical.com/ security and decentralisation. But there is a growing demand for users to move their information and assets between blockchains. Blockchain bridges, also known as cross-chain bridges, solve this problem.

With your WTBC on the Ethereum network, you could use it as you would any other of Ethereum’s tokens. This is because WBTC is essentially an ERC-20 token and operates seamlessly with Ethereum’s ecosystem. Once in the ecosystem, you can also swap or sell those tokens like any other asset on the Ethereum network. Trust is one of the things that blockchain technology epitomizes in reaching consensus.

People make use of blockchain bridges to wrap other cryptocurrencies to be used on other networks. For example, some devs will use a blockchain bridge to explore other blockchain systems to try out native dApps or to take advantage of better interest rates on other networks. Once you locked up your funds in the platform’s smart contract, you would receive wrapped bitcoin (WBTC) on the Ethereum network. For example, a chain anchoring verifiable credentials on Polkadot could be used for KYC (Know Your Customer) requirements by a gaming company built on Ethereum. Bridges allow applications to be even more decentralized, as they are no longer limited by their network of origin. The centralized entity behind a custodial bridge could theoretically steal users’ funds.

Advantages of Using a Blockchain Bridge

It was December 2008 when the concept of blockchain spread around the world with the release of the Bitcoin white paper. A whole new ecosystem has emerged and people’s interest in using programmable blockchains and cryptocurrencies has skyrocketed. Shortly thereafter, various new blockchains emerged based on various consensus protocols. A decentralized exchange (DEX) is a peer-to-peer marketplace that allows users to directly trade with each other.

Off-chain verification can be through a single traditional centralised entity such as Bitgo acting as a custodian to bridge Ethereum and Bitcoin. It can also be through systems that aspire to decentralisation, but that nonetheless ultimately fail the trustless requirement, such as ChainBridge and its system of off-chain relays. Though complicated, the core feature of blockchains is verifying the data they hold without trust. A one-way bridge means that users can only bridge assets to one destination blockchain and not back. The ability to port tokens from a congested or high-fee blockchain to a high-performance blockchain can be revolutionary.

Popular Blockchain Bridge Examples

The distinct traits of the blockchain networks separate them from one another and create distinct communities. For example, each blockchain network features a consensus model, which is an integral component for ensuring that all nodes can agree on specific transactions. The maturity and evolution of blockchain technology have led to the demand for blockchain https://www.xcritical.com/blog/what-is-a-blockchain-bridge-and-how-it-works/ bridge projects to improve interoperability among different blockchain networks. The following discussion offers a detailed introduction to a blockchain bridge and its working alongside the value advantages it presents for the blockchain community. In addition, you can also learn about the risks of a blockchain bridge and examples of projects.

Therefore, a trustless blockchain bridge does not need any central intermediaries or custodians. Blockchain technology has covered quite an extensive journey since its introduction to the world in 2008 with the Bitcoin whitepaper. The subsequent rise in the number of cryptocurrencies and development of blockchain networks with programmability, such as Ethereum, have created a completely new ecosystem. Blockchain promises the value of decentralization and freedom from the control of any individual or institution. However, majority of blockchain networks exist in the form of isolated communities with their own economies. Therefore, blockchain bridges have become one of the inevitable necessities for the decentralized application ecosystem.
