One characteristic of a cross-chain bridge is that it enables users to exchange one cryptocurrency for another without first changing it to fiat currency. Cross-chain bridges aren’t limited to just cryptocurrency value transfer either. An effective cross-chain bridge can also enable the transfer of smart contracts and NFTs from one blockchain environment to another. There are many blockchain networks and cryptocurrencies that use different blockchain technologies, including Bitcoin, Ethereum, Avalanche, Polygon, Solana and Arbitrum. Enabling interoperability and exchange across different blockchain networks is an area where cross-chain bridges — sometimes also referred to as blockchain bridges — play an increasingly important role.
Blockchain bridges can be categorized according to their functions, mechanisms, and levels of centralization. Manual checkpoints are similar to a trusted model as it depends upon a third party, i.e., the officials, for its operations. As a user, you trust the officials to make the right decisions and use your private information correctly. If you’ve been attuned to crypto circles, particularly on platforms like Twitter and Discord, SHIB’s resurgence has been hard to miss. Perhaps the most intriguing aspect is Shibarium’s infrastructure, it is a proof-of-stake (PoS) blockchain, hinging on validators and delegators.
Empowering Cybersecurity with Blockchain
This means they cannot natively communicate, and tokens cannot move freely between blockchains. The main idea of blockchain bridge is to act as a way of interaction between different blockchains. Many blockchains lack interoperability, which means that they cannot communicate well with each other alone. Most commonly, there are no assets actually sent, yet the original asset is locked up in the protocol, while another new token representing the asset is minted on the corresponding blockchain. Blockchain bridges and related assets are also among the hottest crypto assets to trade today. PrimeXBT recently added Polkadot, alongside several other altcoins, next to Bitcoin, Ethereum, and Litecoin.
Through blockchain bridges, token transfers, smart contracts, data exchange, and other feedback and instructions can be exchanged between two independent platforms. Once a user sends https://www.xcritical.com/ crypto or assets from one network to another via a bridge, the assets are not really transferred. Rather, they are locked on the network via smart contracts or other mechanisms.
The Benefits of Blockchain Bridges for DeFi Users
Blockchain technology is a shared, immutable ledger that acts as a digital record for tracking transactions and assets made across a network of users. The asset is most commonly a cryptocurrency, however, the technology behind Ethereum smart contracts allow virtually anything of value to be tokenized and put on the blockchain. Contrary to their name, trustless bridges generally are considered a safer option. They are based on smart contracts rather than a centralized protocol, and users have full control of their funds.
One of the most popular Ethereum-Bitcoin bridges is Bitgo, which uses the centralised bridge approach. It acts as a single trusted Custodian bridging Bitcoin and Ethereum through a lock-mint/burn-release approach. Though complicated, the core feature of blockchains is verifying the data they hold without trust.
Why does blockchain technology needs bridges?
Here is an outline of the notable blockchain bridge variants you can use for transferring assets and information between blockchain networks. A blockchain bridge solves the problem of inter-network communication by offering a way to connect island-like blockchains with each other. 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.
The Cosmos Gravity bridge transfers funds and data back and forth between Ethereum and Cosmos. The Gravity module is implemented on the Cosmos chain and is responsible for minting tokens. A decentralized exchange (DEX) is a peer-to-peer marketplace that allows users to directly trade with each other.

Blockchain bridges utilize wrapped tokens to facilitate interactions between blockchains. While a bridge can alleviate congestion on a busy network, moving assets away to another chain doesn’t solve the https://www.xcritical.com/blog/what-is-a-blockchain-bridge-and-how-it-works/ scalability issue as users won’t always have access to the same suite of dapps and services. For example, some Ethereum dapps are not available on the Polygon Bridge, which limits its scaling efficacy.
- The vast majority of blockchain networks are autonomous communities with separate economies.
- Just like the web3 industry, blockchain bridges are still in the early stages of development.
- The Nodes are continually verifying new blocks of data based on that mechanism.
- Less Bridge is a trustless bridge that allows transferring coins and tokens between 6 blockchain networks including the most demanding Ethereum, Binance Smart Chain, Avalanche, Tron, Polygon, and fantom.
- For example, the Ethereum-Polygon Bridge is a decentralized two-way bridge that works as a scaling solution to the Ethereum network.
Such bridges benefit from high transaction speed, but are limited to just two chains so the goal of greater interoperability is sacrificed. Blockchain bridges enable users to explore various sources, services and applications on different networks. Consequently, when using a bridge to store assets on various chains, the limitations of your source chain do not truly limit you. The future acceptance of blockchain bridges is directly proportional to the development of cross-chain technology. The number of bridges, users, and overall transaction volume being handled across blockchain bridges has increased dramatically.
