What is a cross chain bridge?
https://www.blockchainx.tech/bridge-smart-contract-development
An inter-chain bridge allows the exchange of information, cryptocurrencies, or NFTs from one blockchain network to another. It enables the flow of data and tokens across what would otherwise be isolated data sets on different blockchains .
With fiat currency, there are many established ways for people and businesses to exchange money, creating a globally available and interoperable financial payments system. Those systems include financial institutions, banks, and credit cards that handle foreign exchange. In the world of blockchains, a chain bridge serves a somewhat analogous purpose.
Trading between different blockchains for cryptocurrencies is possible without a cross-chain bridge, but it is expensive and takes more time. Without the use of a cross-chain bridge, users must first convert a cryptocurrency token into fiat currency, which often involves fees. They then use the currency to obtain the other desired type of cryptocurrency, incurring more fees and taking time.
One feature of a cross-chain bridge is that it allows users to exchange one cryptocurrency for another without first exchanging it into fiat currency. Cross-chain bridges are also not just limited to the transfer of cryptocurrency values. An effective cross-chain bridge can also enable the transfer of smart contracts and NFTs from one blockchain environment to another.
There are several approaches to enable transfers with a cross-chain bridge. A common approach is to use a wrapped token issued by the chain bridging provider's platform. With a wrapped token, the value of a token from a specific blockchain network can be encapsulated within another token. Wrapped tokens are generally based on the ERC-20 technical specification for an Ethereum network. For example, WBTC is a bitcoin token wrapped with an ERC-20 Ethereum smart contract.
Another approach to enable cross-chain bridge transfers is through the use of a liquidity pool. With a liquidity pool, a cross-chain bridge provider has an inventory – or pools – of multiple currencies where one can be traded for another.
Chain bridges can also be a lucrative target for hackers. In February 2022, cross-chain bridging platform Wormhole fell victim to an attack in which the threat actor stole 120,000 wrapped Ethereum tokens, worth an estimated $320 million at the time of the theft.
best cross chain bridges
For bitcoin , which is perhaps the best known cryptocurrency, the most common bridge is with the use of Wrapped Bitcoin (WBTC). Wrapped bitcoin is sometimes called a blockchain bridge, as it allows bitcoin to be an ERC-20 token, a token specification compatible with many other blockchains.
While bitcoin is well known, the bitcoin blockchain does not have the same smart contract features that are the foundation of the Ethereum-based blockchain. Smart contracts enable decentralized finance, decentralized applications, and NFTs. Users who wish to use bitcoin on other blockchain networks will first need to convert to Wrapped Bitcoin. This was originally run as a blockchain bridge by BitGo, and in 2022 it is supported and available through a growing network of partner exchanges.
Cross-Chain Bridge
This platform was developed by the Germany-based organization which changed its name to the Autobahn Network in March 2022. Cross-Chain Bridge has support for bridging both tokens and NFTs across multiple networks.
